Why do Some People with Obesity Remain Healthy?

Although obese individuals are at greater risk of diabetes, high blood pressure or high cholesterol, not all obese people develop metabolic diseases of this kind. With around a quarter of all obese individuals are healthy, scientists are trying to work out why some obese people become unhealthy while others do not.

Now, a comprehensive study by researchers from Zurich and Leipzig has provided a vital basis for this work. Specifically, the researchers have produced a detailed atlas with data from healthy and unhealthy overweight people, on their fat (adipose) tissue, and on the gene activity in this tissue’s cells. “Our results can be used to look for cellular markers that provide information on the risk of developing metabolic diseases,” explains Adhideb Ghosh, a researcher in ETH Professor Christian Wolfrum’s group and one of the two lead authors of the study. “The data is also of great interest for basic research. It could help us develop new therapies for metabolic diseases.”

The study appears in Cell Metabolism.

Investigating a large biobank

For this study, Ghosh and his colleagues used the Leipzig Obesity Biobank, an extensive collection of biopsies taken from obese individuals. Compiled by scientists from the University of Leipzig, these samples originate from obese patients who underwent elective surgery and consented to the collection of adipose tissue samples for research purposes. The collection also includes extensive medical information on the patients’ health.

Since the tissue samples were all taken from obese individuals with or without metabolic diseases, they allow comparison between individuals with healthy and unhealthy obesity. In samples from 70 volunteers, the researchers at ETH Zurich examined which genes were active, and to what extent, on a cell-by-cell basis for two types of adipose tissue: subcutaneous and visceral.

Scientists and medical experts assume that visceral fat, which lies deep in the abdominal cavity and surrounds the internal organs, is primarily responsible for metabolic diseases. By contrast, experts generally believe that fat located directly beneath the skin is less problematic.

For the study, it was vital that the adipose tissue cells were not all simply lumped together, as this tissue comprises not only fat cells (adipocytes) but also cells of other types. “In fact, the adipocytes are in the minority,” explains lead author Isabel Reinisch, a postdoc in Wolfrum’s group. A large part of adipose tissue is made up of immune cells, cells that form blood vessels, and immature precursor cells of adipocytes. Another cell type, known as mesothelial cells, are found only in visceral adipose tissue and mark its outer boundary.

Abdominal fat remodelled – and gender differences

As the researchers were able to show, there are significant functional changes in cells in the visceral adipose tissue of people with metabolic diseases. This remodelling affects almost every cell type in this form of tissue. For example, the genetic analyses showed that the adipocytes of unhealthy individuals could no longer burn fats as effectively and instead produced greater quantities of immunologic messenger molecules. “These substances trigger an immune response in the visceral fat of obese people,” explains Reinisch. “It’s conceivable that this response promotes the development of metabolic diseases.”

The researchers also found very clear differences in the number and function of mesothelial cells: in healthy obese individuals, there is a far greater proportion of mesothelial cells in the visceral fat and these cells exhibit greater functional flexibility. Specifically, the cells can switch into a sort of stem cell mode and therefore convert into different cell types, such as adipocytes, in healthy individuals. “The ability of fully differentiated cells to convert into stem cells is otherwise primarily associated with cancer,” says Reinisch. She was surprised, therefore, to find this ability in adipose tissue as well. “We suspect that the flexible cells at the edge of the adipose tissue in healthy obese individuals facilitate smooth tissue expansion.”

Finally, the researchers also found differences between men and women: a certain type of progenitor cell is present only in the visceral fat of women. “This could explain differences in the development of metabolic diseases between men and women,” says Reinisch.

Finding new biomarkers

The new atlas of gene activity in overweight people describes the composition of cell types in adipose tissue and their function. “However, we cannot say whether the differences are the reason why someone is metabolically healthy or whether, conversely, metabolic diseases cause these differences,” says Ghosh. Instead, the scientists view their work as providing the basis for further research. They have published all the data in a publicly accessible web app so that it is available for other researchers to work with.

In particular, this atlas now makes it possible to find new markers that provide information on the risk of developing a metabolic disease. At present, the ETH researchers are also looking for these kinds of markers, which could help to improve the treatment of such diseases. For example, there is a new class of drugs that suppress the appetite and promote insulin release in the pancreas – but these medications are in short supply. “Biomarkers that can be derived from our data could help to identify those patients who are most in need of this treatment,” says Reinisch.

Study Identifies Risk Factors in Heavy Drinkers for Advanced Liver Disease

A new study finds that heavy drinkers with either diabetes, high blood pressure or a high waist circumference are as much as twice as likely to develop advanced liver disease.

The answer may lie in three common underlying medical conditions, according to a new study published in Clinical Gastroenterology and Hepatology from Keck Medicine of USC. The research found that heavy drinkers with either diabetes, high blood pressure or a high waist circumference are as much as 2.4 times more likely to develop advanced liver disease.  

“The results identify a very high-risk segment of the population prone to liver disease and suggest that preexisting health issues may have a large impact on how alcohol affects the liver,” said Brian P. Lee, MD, MAS, a hepatologist and liver transplant specialist with Keck Medicine and principal investigator of the study. 

Diabetes, high blood pressure and a high waist circumference (89cm for women; 101cm for men), which is associated with obesity, belong to a cluster of five health conditions that influence an individual’s risk for heart attack and stroke known as cardiometabolic risk factors.  

Cardiometabolic risk factors have been linked to the buildup of fat in the liver (also known as metabolic dysfunction-associated steatotic liver disease), which can lead to fibrosis, or scarring of the liver. These risk factors affect more than one in three Americans, and cardiometabolic health has been worsening among the population, especially among those under 35, according to Lee.  

Alcohol also causes fat buildup in the liver, and alcohol consumption has been on the rise since the COVID-19 pandemic, said Lee. Due to the prevalence of both cardiometabolic risk factors and drinking in the United States, Lee and his fellow researchers undertook the study to investigate which cardiometabolic risk factors predisposed the liver to damage from alcohol. 

They analysed data from the National Health and Nutrition Examination Survey, a large national survey of more than 40 000 participants, looking at the intersection of heavy drinking, individual cardiometabolic risk factors and the incidences of significant liver fibrosis. Significant liver fibrosis refers to liver scarring that can lead to liver failure.  

For the study, heavy drinking was characterised as 1.5 drinks a day for women (20 grams) and two drinks a day for men (30 grams). 

Researchers discovered that heavy drinkers with either diabetes or a high waist circumference were 2.4 times more likely to develop advanced liver disease and those with high blood pressure 1.8 times more likely. They found that the other two cardiometabolic risk factors – high triglycerides and low HDL (high-density lipoprotein) had less significant correlations to liver disease.  

While the study did not analyse why these three cardiometabolic risk factors are more dangerous for the liver, Lee speculates that these conditions share a common pathway to fat buildup in the liver that when combined with extra fat deposits in the liver from excessive alcohol, can cause significant damage.  

Lee stresses that the study does not imply it is safe for those without these three cardiometabolic risks to consume large amounts of alcohol. “We know that alcohol is toxic to the liver and all heavy drinkers are at risk for advanced liver disease,” he said.  

Lee hopes that the study results will encourage people to consider their individual health and risk profile when making decisions about alcohol consumption. He would also like to see practitioners offer more personalized health screenings and interventions for those who drink with cardiometabolic risk factors so that liver damage among this high-risk group can be caught early and treated.

What’s the Mechanism behind Behavioural Side Effects of GLP1RAs?

Photo by I Yunmai on Unsplash

Glucagon-like peptide 1 receptor agonists (GLP1RA) – medications for type 2 diabetes and obesity that have recently been making headlines due to a rise in popularity as weight loss agents – have been linked with behavioural side effects. A large population-based analysis in Diabetes, Obesity and Metabolism assessed whether certain genetic variants might help explain these effects.

GLP1RA mimic the GLP-1 hormone in the body that helps control insulin and blood glucose levels and promotes feelings of satiety. GLP-1 binds to GLP1R on cells in the brain and pancreas.

Observational and epidemiological studies have shown that there may be neutral or protective effects of GLP1RAs on mental health symptoms. However, a study based on individuals taking GLP1RA suggests there is increased prescription of anti-depressants when used for treatment of diabetes. Early evidence in animal models suggest GLP1RA may decrease depressive and anxious symptoms, potentially presenting new treatment pathways; however, comparing these studies to human clinical evidence will not be possible for some time.

For the analysis, investigators examined common genetic variants in the GLP1R gene in 408 774 white British, 50 314 white European, 7 667 South Asian, 10 437 multiple ancestry, and 7641 African-Caribbean individuals.

Variants in the GLP1R gene had consistent associations with cardiometabolic traits (body mass index, blood pressure, and type 2 diabetes) across ancestries. GLP1R variants were also linked with risk-taking behavior, mood instability, chronic pain, and anxiety in most ancestries, but the results were less consistent. The genetic variants influencing cardiometabolic traits were separate from those influencing behavioral changes and separate from those influencing expression levels of the GLP1R gene.

The findings suggest that any observed behavioral changes with GLP1RA are likely not acting directly through GLP1R.

“Whilst it is not possible to directly compare genetic findings to the effects of a drug, our results suggest that behavioural changes are unlikely to be a direct result of the GLPRAs. Exactly how these indirect effects are occurring is currently unclear,” said corresponding author Rona J. Strawbridge, PhD, of the University of Glasgow, in the UK.

In Obesity or Not, Individuals Prefer High-calorie Food

Calorie content drives food preference despite similar taste in individuals with and without obesity

Higher calorie foods were preferred among individuals with and without obesity despite similar taste and texture, according to a study published December 17th in the open-access journal PLOS Biology by Albino Oliveira-Maia from the Champalimaud Foundation, Portugal, and colleagues.

Eating sends signals to the brain with information about a food’s energy content, which can influence food preferences irrespective of flavor. People with obesity often have impairments in areas of the brain where dopamine is released, which may drive reward-related eating and a preference for energy-dense foods rich in fat and sugars. Weight loss due to bariatric surgery has been associated to a normalization of reward-related eating with a shift of preferences toward healthier options, but the underlying mechanisms are not well understood.

In this study, after examining a large group of healthy volunteers, researchers compared food preferences in three groups: 11 individuals with obesity, 23 post-bariatric surgery patients, and 27 non-obese control subjects. They gave participants sweetened low-fat yogurt with and without maltodextrin (a carbohydrate that adds calories to the yogurt with no impact on taste or texture). Participants ate the yogurt at home, alternating between the maltodextrin-containing and -free yogurt. All three groups ate more of the maltodextrin-containing yogurt, despite rating both as equally pleasant. Somewhat unexpectedly, the effects of maltodextrin on yogurt consumption were similar in individuals with obesity relative to their non-obese counterparts.

The study also used radioactive iodine labelling and single photon emission computed tomography to visualise dopamine receptors in the brain. Consistent with previous studies, individuals with obesity had lower dopamine receptor availability than non-obese controls. Dopamine receptor availability was similar in the surgical and non-obese groups and was associated with more restrained eating. These results suggest that obesity-related brain changes can be reversed after bariatric surgery, potentially impacting the amount of food consumed but not necessarily the types of food preferred.

The authors add, “We were very intrigued that, while behaviour was guided towards eating yoghurts with higher energy-content, this did not seem to be a result of explicit choices, since consistent changes in pleasantness of flavours enriched with carbohydrates were not found. Importantly, this behaviour was maintained in patients with obesity and after weight-loss surgery, even though there were important differences in their brain dopaminergic system.”

Treatment for Children with Obesity has Lasting Effect

Photo by Patrick Fore on Unsplash

When children with obesity undergo weight-loss treatment, the effects have repercussions later in life and the risk of serious health problems and premature death is lower as they reach young adulthood. However, this is not the case for depression and anxiety, a study from Karolinska Institutet published in JAMA Pediatrics reports.

The study shows that children and adolescents who respond well to obesity treatment are less likely to develop obesity-related diseases, such as type 2 diabetes, hypertension and dyslipidaemia as young adults.  

The treatment studied involved support for children with obesity and their families designed to motivate healthy diets, exercise and sleep habits – what is known as “behavioural lifestyle therapy”.  

“The results are very good news,” says the study’s last author Emilia Hagman, principal researcher at the Department of Clinical Science, Intervention and Technology, Karolinska Institutet. “Whether or not the treatment of obesity in childhood has long-term health benefits have been debated, since weight-loss is hard to maintain.”

Higher risk of dying as young adults

The study shows that children with obesity who respond to treatment also run a lower risk of premature death. A previous study, published in PLOS Medicine by the same research group, has shown that children with obesity have a much higher mortality risk in early adulthood, and were much more likely to die from suicide and somatic conditions. Just over a quarter of deaths were obesity-related.

“This emphasises the importance of providing early treatment, as we know that timely intervention increases the likelihood of success and helps mitigate the long-term health risks associated with obesity,” says Dr Hagman.

Depression and anxiety are not affected

However, the risk of depression and anxiety was not affected by the treatment outcomes in childhood, the JAMA Pediatrics paper shows. No matter the outcome of obesity treatment in childhood, the risk of anxiety and depression was unchanged in young adulthood.

“It has been believed that weight loss could decrease symptoms of depression and anxiety, but we can now show that it’s not the case,” says Dr Hagman. “Even though there’s a link between the two comorbidities, they must be treated in parallel.”

The study included over 6700 individuals who had received treatment for obesity during childhood identified via the BORIS register (the Swedish Childhood Obesity Treatment Register) and who were then followed up as young adults in the Swedish Patient Register, the Prescribed Drugs Register and the Cause of Death Register. A control group from the general population was also used, matched by age, sex and place of residence.

GLP1 analogues, which have become popular obesity drugs in recent years, were not part of the study as they were yet approved when the study participants were being treated for obesity. As Dr Hagman points out, it is still uncommon for this type of drug to be administered to children.

“I’m in favour of their use as these drugs eases feelings of hunger, which is something that some children struggle with” she says. “That said, lifestyle therapy is still the foundation of all treatments for childhood obesity.”

The research group will now be trying to identify therapy options that are most effective for different individuals and the health/risk markers that are significant for future health.

Millions of Diabetes and Heart Disease Cases Linked to Sugary Drinks, New Study Finds

Photo by Breakingpic on Pexels

A new study from researchers at Tufts University, which appears in Nature Medicine, estimates that 2.2 million new cases of type 2 diabetes and 1.2 million new cases of cardiovascular disease occur each year globally due to consumption of sugar-sweetened beverages.

In developing countries, the case count is particularly sobering. In Sub-Saharan Africa, the study found that sugar-sweetened beverages contributed to more than 21% of all new diabetes cases. In Latin America and the Caribbean, they contributed to nearly 24% of new diabetes cases and more than 11% of new cases of cardiovascular disease.

Colombia, Mexico, and South Africa are countries that have been particularly hard hit.  More than 48% of all new diabetes cases in Colombia were attributable to consumption of sugary drinks. Nearly one third of all new diabetes cases in Mexico were linked to sugary drink consumption. In South Africa, 27.6% of new diabetes cases and 14.6% of cardiovascular disease cases were attributable to sugary drink consumption.

Sugary beverages are rapidly digested, causing a spike in blood sugar levels with little nutritional value. Regular consumption over time leads to weight gain, insulin resistance, and a host of metabolic issues tied to type 2 diabetes and heart disease, two of the world’s leading causes of death.

“Sugar-sweetened beverages are heavily marketed and sold in low- and middle-income nations. Not only are these communities consuming harmful products, but they are also often less well equipped to deal with the long-term health consequences,” says Dariush Mozaffarian, senior author on the paper and director of the Food is Medicine Institute at the Friedman School.

As countries develop and incomes rise, sugary drinks become more accessible and desirable, the authors say. Men are more likely than women to suffer the consequences of sugary drink consumption, as are younger adults compared to their older counterparts, the researchers say.

“We need urgent, evidence-based interventions to curb consumption of sugar-sweetened beverages globally, before even more lives are shortened by their effects on diabetes and heart disease,” says Laura Lara-Castor, NG24, first author on the paper who earned her PhD at the Friedman School and is now at the University of Washington.

The study’s authors call for a multi-pronged approach, including public health campaigns, regulation of sugary drink advertising, and taxes on sugar-sweetened beverages.  Some countries have already taken steps in this direction. Mexico, which has one of the highest per capita rates of sugary drink consumption in the world, introduced a tax on the beverages in 2014. Early evidence suggests that the tax has been effective in reducing consumption, particularly among lower-income individuals. 

“Much more needs to be done, especially in countries in Latin America and Africa where consumption is high and the health consequence severe,” says Mozaffarian. “As a species, we need to address sugar-sweetened beverage consumption.”

GLP-1 Receptor Agonists also Protect the Kidneys, Study Shows

GLP-1 agonists significantly reduced kidney deterioration and failure, regardless of diabetes status

The biggest and most comprehensive analysis of glucagon-like peptide-1 (GLP-1) receptor agonists on kidney and cardiovascular outcomes shows they have significant benefits in people with and without diabetes.1 Findings appear in The Lancet Diabetes & Endocrinology.

Originally developed to treat diabetes, GLP-1 receptor agonists mimic the action of glucagon-like peptide 1, a hormone which stimulates insulin production and lowers blood sugar levels. More recently, they have emerged as effective treatments for obesity – slowing digestion, increasing satiety and reducing hunger. 

But while the benefits of GLP-1 receptor agonists for the treatment of type 2 diabetes, obesity and cardiovascular disease are well known, their impact on chronic kidney disease (CKD) has been less certain.

Researchers conducted a meta-analysis of 11 large-scale clinical trials of GLP-1 receptor agonists involving a total of 85 373 people (79.4% with type 2 diabetes and 20.6% with overweight or obesity and cardiovascular disease but without diabetes). Seven different GLP-1 receptor agonists were investigated among the trials. 

The results showed that compared to placebo, GLP-1 receptor agonists reduced the risk of kidney failure by 16% and the worsening of kidney function by 22% (defined by a drop in estimated glomerular filtration rate – a measure of how much blood the kidneys filter clean every minute – of at least 50%). The combined reduction in the risk of kidney failure, worsening kidney function, and death due to kidney disease was 19%. 

The analysis also confirmed previous findings that GLP-1 receptor agonists protect cardiovascular health, with a 14% reduction in the risk of cardiovascular death, non-fatal heart attack, and non-fatal stroke, compared to placebo. Death by any cause was 13% lower among patients treated with GLP-1 receptor agonists.

Lead author Professor Sunil Badve, Professorial Fellow at The George Institute for Global Health and UNSW Sydney said the study expanded current knowledge about this class of drugs in key areas, including benefits in people with CKD, and in people with and without diabetes. 

“This is the first study to show a clear benefit of GLP-1 receptor agonists on kidney failure or end-stage kidney disease, suggesting they have a key role in kidney-protective and heart-protective treatment for patients with common medical conditions like type 2 diabetes, overweight or obesity with cardiovascular disease, or CKD,” he said.

“These results are particularly important for patients with chronic kidney disease. It is a progressive condition eventually leading to kidney failure requiring dialysis or kidney transplantation and is associated with premature death, mostly from heart disease. It has a significant impact on patients’ quality of life and incurs substantial healthcare costs.” 

CKD is estimated to affect one in ten people worldwide, equivalent to around 850 million people.2 It is the tenth leading cause of death and is projected to become the fifth most common cause of death by 2050.3 Diabetes, cardiovascular disease and obesity are independent risk factors for CKD and represent a major global health burden.4

New Study Investigates How Jetlag can Disrupt Metabolism

Photo by Andrea Piacquadio: https://www.pexels.com/photo/young-man-in-sleepwear-suffering-from-headache-in-morning-3771115/

A new study from the University of Surrey and the University of Aberdeen has found that disruptions to our body clock, such as those experienced during jetlag, impact our metabolism – but to a lesser extent than sleepiness and the primary clock in the brain. 

Led by Professor Jonathan Johnston at the University of Surrey and Professor Alexandra Johnstone at the University of Aberdeen, the research involved a controlled experiment where participants experienced a 5-hour delay in their bedtime and mealtimes.  

The study, published on iScience, highlights that the time shifts lead to: 

  • Reduced energy spent processing meals. 
  • Changes in blood sugar and fat levels. 
  • Slower release of breakfast contents from the stomach. 

These metabolic effects were temporary, however, and mostly recovered within 2-3 days of the 5-hour time delay. This was in marked contrast to the main clock in the brain, plus feelings of sleepiness and alertness, which had not recovered within 5 days of the 5-hour time delay. 

Our research underscores the importance of maintaining a consistent sleep schedule, particularly in our fast-paced world in which long trips and shift work are ever so common. Even a small time shift can impact many aspects of metabolism, but it now seems that metabolic consequences of jetlag recover far more quickly than impairment of sleep and alertness. Understanding the impact of circadian rhythms on our health can help us make informed choices about our lifestyle. By optimising our sleep and eating patterns, we can improve our overall wellbeing.

Long-term Study Finds Link between Earlier Diabetes Diagnosis and Dementia Risk

Photo by Nataliya Vaitkevich on Pexels

People diagnosed with type 2 diabetes at a younger age are at a higher risk for developing dementia than those diagnosed later in life, according to a study led by researchers at the NYU Rory Meyers College of Nursing. The findings, published in PLOS ONE, show that the increased risk is especially pronounced among adults with obesity.

“Our study suggests that there may be cognitive consequences to earlier onset type 2 diabetes, and it points to the need for strategies to prevent dementia that consider both diabetes and obesity,” said Xiang Qi, assistant professor at NYU Meyers and the study’s first author.

Type 2 diabetes is a known risk factor for dementia. Although the underlying mechanisms are not fully understood, scientists think that some of the hallmarks of diabetes, such as high blood sugar, insulin resistance, and inflammation, may encourage the development of dementia in the brain.

While type 2 diabetes was once a disease of older adults, it is increasingly prevalent among younger individuals: one in five people with type 2 diabetes worldwide is under 40 years old.

To understand how the timing of a type 2 diabetes diagnosis relates to dementia risk, the research team analyzed data from 2002 to 2016 in the Health and Retirement Study, a longitudinal study conducted by the University of Michigan Institute for Social Research. The PLOS ONE study included 1213 US adults aged 50 and over with type 2 diabetes confirmed by blood tests, without dementia at baseline. Following participants for up to 14 years, 216 (17.8%) developed dementia based on follow-up telephone interviews.

The researchers found that adults diagnosed with type 2 diabetes at younger ages were at increased risk for developing dementia, compared to those diagnosed at 70 years or older. Adults diagnosed with diabetes before age 50 were 1.9 times as likely to develop dementia as those diagnosed at 70 and older, while those diagnosed between 50–59 years were 1.72 times as likely and those diagnosed between 60–69 years were 1.7 times as likely.

Using linear trend tests, the researchers found a graded association between age at diagnosis and dementia risk: for each year younger a person is at the time of their type 2 diabetes diagnosis, their risk for developing dementia increases by 1.9%.

“While we do not know for sure why an earlier diabetes diagnosis would increase the risk for dementia, prior studies show that people diagnosed with type 2 diabetes in mid-life may experience more vascular complications, poor blood sugar control, and insulin resistance – all of which are known risk factors for cognitive impairment,” said Bei Wu, the Dean’s Professor in Global Health and vice dean for research at NYU Meyers and the study’s senior author.

In addition, obesity appeared to influence the relationship between type 2 diabetes and dementia. Individuals with obesity who were diagnosed with type 2 diabetes before age 50 had the highest dementia risk in the study.

The researchers note that this greater understanding of the connection between diabetes onset, obesity, and dementia may help inform targeted interventions to prevent dementia.

“Our study highlights the importance of one’s age at diabetes diagnosis and suggests that specifically targeting obesity – whether through diet and exercise or perhaps medication – may play a role in staving off dementia in younger adults with diabetes,” said Wu.

How Organisations Can Support Mobile Workforces with Diabetes – From Prevention to Management

Photo by Nataliya Vaitkevich on Pexels

As global mobility surges, managing chronic conditions like diabetes during travel has become a significant concern. Diabetes remains one of the fastest-growing global public health issues1,affecting approximately 422 million people worldwide and causing 1.5 million deaths annually.2 International SOS, the world’s leading health and security services company, has reported a significant year-on-year increase in diabetes-related assistance cases over the past three years, with a 28% increase in 2022 and a 32% increase in 2023.

Meanwhile, year-to-date 2024 data indicates a further uptick.3 With World Diabetes Day approaching on 14 November, organisations are urged to support diabetes prevention and management strategies. This year’s theme, ‘Breaking Barriers, Bridging Gaps’4 highlights the need for equitable, comprehensive and affordable diabetes care.

Dr Katherine O’Reilly, Regional Medical Director at International SOS, emphasises the importance of comprehensive health strategies: “It is important for organisations to understand the unique challenges that employees with diabetes face, particularly when travelling. By recognising these specific needs, companies can provide the necessary support and resources to help their employees manage their condition effectively. This ensures that employees can maintain their health and productivity, even when they are on the go. With thoughtful planning and the right resources, organisations can help their employees navigate the complexities of diabetes, fostering a supportive and inclusive work environment.”

People with diabetes face a double burden: a higher risk of life-threatening conditions like heart attack, stroke, and kidney failure, compounded by the psychological toll of diabetes distress. Individuals with diabetes are two to three times more likely to experience depression compared to those without the condition.5 These challenges can significantly impact employee wellbeing, leading to increased absenteeism, reduced productivity, and higher healthcare costs for employers.

According to The International Diabetes Federation (IDF), the global healthcare costs for individuals living with diabetes are expected to exceed $1054 billion by 2045.6 Furthermore, the prevalence of diabetes is projected to rise, with 643 million people affected by 2030, and 783 million by 2045.With this rising prevalence, it is crucial for organisations to implement strategies that help their workforce manage and prevent this chronic condition. Minor adjustments can reduce absenteeism, increase productivity, concentration and energy levels, and reduce the chance of on-the-job injury.

Dr Katherine O’Reilly continues, “Early diagnosis is crucial. Raising awareness about diabetes symptoms can prompt people to get screened, enabling early detection and intervention to prevent or delay its onset.  This proactive approach can prevent undiagnosed diabetes from causing severe health complications, affecting various organ systems, including eye damage, heart and kidney disease, nerve damage and poor wound healing. By prioritising employee health, organisations can enhance productivity and foster a more engaged and resilient workforce. This approach also promotes a positive work environment and supports overall employee wellbeing.”


International SOS offers five tips for organisations to support employees in managing and preventing diabetes:

  1. Education and awareness: Increase awareness about diabetes symptoms to encourage early diagnosis and effective management, thereby preventing severe health complications.
  2. Provide comprehensive health solutions: Offer resources such as dietary guidelines, exercise programmes and regular health screenings to help employees manage their diabetes.
  3. Supportive culture and policies: Develop and implement policies allowing for flexible work schedules and access to medical care while travelling. Foster a culture that prioritises health and wellbeing by accommodating regular meals and exercise, and ensuring employees have time to rest and recover from travel.
  4. Promote a healthy lifestyle: Offer guidance on maintaining a healthy diet and regular exercise. Provide resources such as a list of healthy meal options and tips for finding nutritious food in different locations.
  5. Facilitate health monitoring and provide adjustments: Ensure employees have scheduled breaks to take medication, check blood sugar levels and eat regular meals. Provide a private space for insulin administration and other medical needs.
