When was the last time you measured your waistline? If you assume that BMI is the only number to focus on when it comes to your health, think twice. New research has revealed a shocking revelation—your waist circumference might be a far better predictor of men's cancer risk than BMI.
The study finds that for each 4-inch increase in waist size, a man's risk of cancer increases by a staggering 25%. Meanwhile, BMI, commonly regarded as the gold standard for assessing obesity, raises cancer risk by only 19% for the same weight gain. So, if you've been dismissing that pesky belly fat, it's time to take notice.
But why is your waistline so important? The reason is visceral fat—the hidden, deep fat that accumulates around your organs. Unlike other body fat, visceral fat is a stealthy troublemaker, causing inflammation, insulin resistance, and abnormal blood fat levels—all of which combine to create a cancer-perfect storm.
Obesity has been associated with an increased risk of numerous health conditions, including cancer, for decades. The research, though, indicates that a specific measure of the body—waist circumference—may be an even more reliable forecaster of cancer risk in men than the more frequently employed Body Mass Index (BMI). This finding emphasizes the need to pay particular attention to the distribution of fat and not merely to the weight of the body.
BMI has been the go-to measure for years for gauging health risks related to obesity. New research, though, that appears in The Journal of the National Cancer Institute indicates that waist measurement is a better predictor of cancer risk in men. According to the research, four more inches (10 cm) around the waist will add 25% to a man's cancer risk. Conversely, a 3.7 kg/m² rise in BMI (from a BMI of 24 to 27.7) increased cancer risk by only 19%.
Why is waist circumference a better predictor, then? Unlike BMI, which measures weight relative to height, waist circumference actually measures abdominal fat—specifically, visceral fat. This type of fat encircles internal organs and is also linked to higher levels of inflammation, insulin resistance, and abnormal blood lipids, all of which are factors in cancer growth. BMI, however, does not measure fat distribution, so two individuals with the same BMI can have very different levels of health risk depending on where fat is deposited on their bodies.
Interestingly, the research identified a significant difference between men and women when it came to waist circumference and cancer risk. Although waist circumference and BMI were linked with obesity-related cancers in women, the relationship was weaker than for men. An increase of 12 cm (4.7 inches) in waist size or a 4.3 rise in BMI (from 24 to 28.3) raised the cancer risk in women by just 13%—a much lower percentage than for men.
Experts credit this difference to the way that fat is stored in the body. Men are more likely to carry fat around the abdomen, especially as visceral fat, which is more metabolically active and associated with cancer-producing biological alterations. Women, by contrast, store fat in peripheral sites such as the hips and thighs, where it is less likely to drive systemic inflammation and metabolic disturbances.
A possible reason is that men tend to depot fat more in the visceral regions, whereas women tend to carry more subcutaneous and peripheral fat," wrote the researchers. "This may render waist circumference a more robust risk factor for cancer in men and account for why waist circumference provides additional risk information beyond BMI in men but not women."
The research used the International Agency for Research on Cancer (IARC) data to define obesity-related cancers. These cancers are esophageal (adenocarcinoma), gastric (cardia), colorectal, rectal, liver, gallbladder, pancreatic, renal, and thyroid cancers, and multiple myeloma and meningioma. In men, abdominal obesity is especially significant in raising the risk of these cancers through high levels of insulin and markers of inflammation.
For women, the research proposes that both waist circumference and hip circumference may give a more accurate estimate of visceral fat and cancer risk. "Adding hip circumference to risk models could strengthen the link between waist circumference and cancer, especially in women," researchers observed.
With these results, doctors advise men to be more mindful of their waistline than only their BMI. Waist size is an easy method to gauge health risk, and its maintenance through lifestyle changes might be the key to cancer prevention.
Track Your Waist Size: Regularly measure your waist circumference and try to keep it in a healthy range (below 40 inches for men, according to medical advice).
Eat a Balanced Diet: A diet containing high fiber, lean protein, and healthy fats can assist in limiting visceral fat gain.
Exercise Consistently: Regular exercise with a combination of aerobic and strength training will help maintain a healthy waistline.
Control Stress and Sleep: Persistent stress and inadequate sleep tend to cause weight gain, especially in the midsection of the body.
Regular Health Screenings: Early identification of cancer risk factors through regular screening can greatly enhance long-term health status.

Epilepsy is one of the most common neurological disorders and a leading cause of disability worldwide. Research has suggested that associated conditions, such as stigma, anxiety, and depression, can sometimes be more debilitating than the seizures themselves.
Stigma related to epilepsy can exist at both societal and individual levels, with many patients experiencing feelings of shame, fear, discrimination, and social isolation.
Now, research led by AIIMS New Delhi has suggested that yoga may help reduce epilepsy-related stigma while also improving seizure control. The 2023 study, published in Neurology, found that yoga-based interventions may offer benefits for both mental well-being and disease management.
“Yoga has been clinically proven to reduce the ‘felt stigma’ associated with epilepsy. By alleviating anxiety and improving both mindfulness and overall quality of life, mind-body interventions empower individuals to feel more in control and less socially isolated,” lead author Dr. Manjari Tripathi, Head of the Department of Neurology at AIIMS, told HealthandMe.
According to Dr. Manjari, the study identified three key benefits of yoga for people living with epilepsy:

Dr. Rajesh Sagar, Professor of Psychiatry at AIIMS, told HealthandMe that yoga reduced the burden of epilepsy and improved the overall quality of life in epilepsy patients by reducing the perceived stigma. The overall quality of life was also improved in the yoga group.

Researchers conducted a randomized clinical trial involving 160 adults with epilepsy who were followed for six months. Participants were assigned either a structured yoga program or a sham yoga intervention, while both groups also received epilepsy-related psychoeducation.
The yoga program included loosening exercises , breathing techniques, meditation, and positive affirmations.
While the impact on seizure frequency was reduced compared with the control group, the researchers cautioned that larger studies are needed to conclusively determine the effect of yoga on seizure control.
Further, mood disturbances have been common among people with epilepsy and often remain inadequately addressed, particularly in developing countries.
According to the researchers, yoga may offer a scalable and accessible option for helping patients manage these challenges alongside conventional treatment.
Dr. Rajesh further told HealthandMe that yoga has well-established benefits for mental health.
“Yoga is important in mental health care, and it has been found that the three important things, which are pranayama, that is, breathing techniques, asanas, that is, physical posture, and dhyana, that is, meditation, have a positive effect on anxiety and even depression, and also improve sleep".
He added that yoga can help reduce stress, improve mood, lower anxiety levels, and enhance sleep quality.
“There is substantial evidence from around the world showing that yoga can benefit people living with certain mental health disorders,” he said.

Every morning, millions begin their day with a quick breakfast and blood pressure (BP) medication swallowed mechanically. But what happens when BP remains uncontrolled despite medicines? Uncontrolled hypertension is one of the most underestimated health threats. Often called the silent killer, it quietly damages the heart, brain, kidneys, and blood vessels.
The BP reading on the cuff captures only a visible measurement. BP that remains above goal over time despite treatment is concerning. Hypertension affects approximately 1.4 billion adults worldwide. Studies suggest that almost 54% of Indian patients have uncontrolled hypertension even while taking ≥2 medications. Thus, treatment does not necessarily mean control.
Global organizations recommend stricter BP targets, aiming for readings below 130/80 mmHg or even 120 mmHg if tolerated. Studies show that each 10 mmHg reduction in systolic BP can decrease the risk of major cardiovascular events by 20%, stroke by 27%, heart failure by 28%, and death by 13%.
On the other hand, uncontrolled hypertension increases the risk of heart attacks, strokes, heart failure, end-stage kidney disease, type 2 diabetes, and death.
In persistently uncontrolled hypertension that other causes cannot explain, a hidden culprit called aldosterone is an under-recognized driver. Normally, aldosterone balances sodium and water to regulate BP.
However, in patients with uncontrolled hypertension, aldosterone production may remain abnormally high, causing sodium and fluid buildup, increasing BP.
Approximately 30% of patients with hypertension may have aldosterone dysregulation, and patients with resistant hypertension, obesity, type 2 diabetes, sleep apnea, and hypokalemia are at greater risk. Nearly 10–20% of patients with hypertension are treatment resistant, increasing their risk. In these patients, aldosterone dysregulation could be an important cause.
It is time to look beyond the cuff, as uncontrolled hypertension is a chronic, progressive, and often silent condition with serious consequences. Improving patient outcomes requires greater urgency, earlier intervention, better treatment optimization, and stronger awareness of underlying drivers such as aldosterone.
It is time to identify and treat the root causes of uncontrolled hypertension, so that patients can regain lasting BP control.

Inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, affects millions of people worldwide. The lifelong condition commonly begins in adolescence or early adulthood and can require repeated hospital treatment, long-term immunosuppressive medication, and, in some cases, surgery.
Despite advances in treatment, many patients cycle through multiple therapies without achieving lasting disease control, impacting their lives and costing healthcare systems millions.
Now, a team of UK researchers from the Universities of Oxford, Newcastle, and Cambridge has identified an important driver of inflammatory bowel disease (IBD).
The findings, published in the New England Journal of Medicine, suggest that inflammatory bowel disease is not a single condition but a group of biologically distinct diseases driven by different underlying mechanisms.
"Understanding what drives the inflammation provides a clear explanation for disease in this group of people and opens the door to new treatments that target the autoantibodies themselves or cells that produce those autoantibodies," said Professor Holm Uhlig, a pediatric gastroenterologist and director of the Centre for Human Genetics, Nuffield Department of Medicine, University of Oxford.

The researchers analyzed more than 4,900 patients with IBD and discovered that:
Antibodies that block interleukin-10 (IL-10), a cell-to-cell messenger that normally acts as one of the body's key controls on inflammation, effectively remove the immune system's natural "brake" on inflammation, allowing inflammatory responses to continue unchecked.
The researchers found high levels of anti-IL-10 neutralizing autoantibodies in the blood of about 3.5% of IBD patients, including those with Crohn's disease and ulcerative colitis, but not in healthy individuals. This could equate to 15,000–20,000 people with IBD in the UK carrying these autoantibodies.

The researchers also found that the presence of these antibodies was strongly linked to carriage of a particular genetic variant known as HLA-DRB1*01:03.
The link between HLA-DRB1*01:03 and a severe form of inflammatory bowel disease was first identified by Oxford researchers 30 years ago.
The new findings show that people carrying this variant are far more likely to develop antibodies that block IL-10, helping explain how the gene contributes to disease.
The researchers say the findings support the development of a blood test to identify this subgroup of patients, helping clinicians move quickly toward more appropriate treatment.
As per the Centers for Disease Control and Prevention (CDC), IBD refers to a group of lifelong diseases that affect your intestines. The main types of IBD are ulcerative colitis and Crohn's disease.
Ulcerative colitis affects the large intestine, while Crohn’s disease can inflame any part of the digestive tract. Both are lifelong conditions of unknown cause that trigger abdominal pain, diarrhea and other complications, with no known cure.
