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.

Why Men Are at Higher Risk?

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."

Cancer Types Most Linked to Abdominal Fat

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.

What This Means for Men's Health and Cancer Prevention?

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.

How To Reduce Cancer Risk In Men?

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.

When we think of perimenopause, irregular periods, hot flashes and mood changes usually come to mind. But the transition to menopause is not limited to the menstrual cycle. Behind the scenes, changing ovarian hormones—particularly fluctuating and eventually declining estrogen—can influence body composition, insulin sensitivity, cholesterol levels, bone health and cardiovascular risk.

For many women, these metabolic changes begin years before their final menstrual period.

Why does weight suddenly behave differently?

A common concern during perimenopause is: “I haven’t changed my diet, so why am I gaining weight around my abdomen?”

Ageing itself contributes to gradual loss of muscle mass and changes in energy expenditure. At the same time, the menopausal transition is associated with a shift in fat distribution, with a greater tendency to accumulate visceral or abdominal fat.

This matters because visceral fat is metabolically active. An increase in abdominal fat can be associated with insulin resistance, abnormal cholesterol levels and a higher risk of metabolic disease. So, the change in waist circumference may sometimes tell us more about metabolic health than the number on the weighing scale alone.

Blood sugars may raise up too

Estrogen interacts with several pathways involved in glucose and fat metabolism. During midlife, changes in body composition, reduced physical activity, sleep disturbance and hormonal changes can collectively make insulin sensitivity less favourable.

This does not mean every woman going through perimenopause will develop diabetes. However, women who already have risk factors—such as overweight or obesity, prediabetes, a history of gestational diabetes or a strong family history of type 2 diabetes—should be particularly mindful.

Cholesterol and heart health deserve attention

The menopausal transition can also be accompanied by unfavourable changes in the lipid profile, including changes in LDL cholesterol. Cardiovascular risk increases with age, and menopause is an important time to reassess risk factors such as blood pressure, glucose, cholesterol, smoking, physical activity and body composition.

Women often spend years focusing on reproductive health while overlooking these equally important metabolic markers.

Muscles and bones need attention as well

Midlife is also an important period for protecting muscle and bone. Declining estrogen after menopause accelerates bone loss, while ageing contributes to loss of muscle mass.

Resistance training therefore becomes especially valuable. Adequate protein intake, regular weight-bearing exercise, sufficient calcium and vitamin D, good sleep and avoiding smoking can support healthier ageing.

What should women do?

Perimenopause should not be viewed as a disease, nor should every symptom or kilogram gained in midlife automatically be blamed on hormones. Instead, it is an opportunity for a metabolic health check.

Women should discuss appropriate screening for blood pressure, blood glucose or HbA1c, lipid profile, weight and waist circumference monitoring , DEXA scan for bone health, depending on their individual risk factors.

Most importantly, don’t wait for menopause to start thinking about metabolic health. The perimenopausal years can be an important window to build muscle, improve fitness, optimise nutrition and identify metabolic risk early.

Perimenopause is more than a change in periods—it is a transition in whole-body health. Understanding these changes early can help women enter the next phase of life stronger, healthier and better prepared.

Loud habitual snoring is often dismissed as a nuisance or simply a part of sleeping. For some people, it may be an early warning sign of obstructive sleep apnoea, a condition in which breathing repeatedly slows or stops during sleep. When left unaddressed, sleep apnoea can quietly strain the heart and blood vessels, increasing the risk of blood pressure, irregular heart rhythms, heart attack and stroke.

Snoring happens when relaxed tissues in the throat vibrate as air moves through a narrowed airway. Not everyone who snores has a problem and occasional snoring is common. However loud and regular snoring, especially when a bed partner notices pauses in breathing, choking or gasping should not be ignored. It may indicate sleep apnoea, where the airway collapses repeatedly during sleep.

Each time breathing stops, oxygen levels drop. The brain briefly wakes the body up to restart breathing. Most people do not remember these interruptions but their body feels the effects. Over time, this cycle can disturb sleep, raise blood pressure, increase inflammation and put pressure on the cardiovascular system.

Risk factor & symptoms

Sleep apnoea is increasingly recognised as a risk factor for stroke. It can worsen hypertension. Contribute to atrial fibrillation, an irregular heartbeat that raises the likelihood of a stroke. The concern becomes greater in people who already have conditions such as diabetes, obesity, high cholesterol or a family history of heart disease.

For them, untreated sleep apnoea may add to the strain on the heart and blood vessels. A landmark study by the All India Institute of Medical Sciences (AIIMS) New Delhi estimates that roughly 104 million Indians suffer from Obstructive Sleep Apnea (OSA), with about 47 million cases classified as moderate to severe.

There are also signs that should prompt a conversation with a doctor. Waking up unrefreshed despite spending hours in bed, feeling excessively sleepy during the day, experiencing morning headaches, and struggling to concentrate or becoming unusually irritable can all be linked to poor-quality sleep caused by sleep apnoea. If snoring is accompanied by any of these symptoms a sleep study may be recommended to confirm whether it is snoring or a more serious breathing disorder.

Remedies

The reassuring part is that sleep apnoea is treatable. Depending on its cause and severity, doctors may suggest weight management where relevant, avoiding alcohol and sedatives close to bedtime, treating congestion, changing sleep position, using an oral appliance or undergoing CPAP therapy, which keeps the airway open during sleep.

The message is not to worry about every snore but to take loud snoring seriously particularly when it comes with breathing pauses or daytime tiredness. Early diagnosis can improve sleep, energy and overall quality of life while helping reduce long-term risks to the heart and the brain.

Perimenopause is often described as a transition marked by hot flashes, mood swings and irregular periods. Because these changes are common, many women simply accept them as an inevitable part of ageing. But the years around menopause are also an important turning point for cardiovascular health.

The connection is partly hormonal. As ovarian function changes, oestrogen levels fluctuate and eventually decline. Oestrogen has several favourable effects on the cardiovascular system, including effects on blood vessels, cholesterol metabolism and vascular function. Its decline does not suddenly “cause” heart disease, but it can coincide with changes in blood pressure, cholesterol, body fat, glucose metabolism and vascular health that collectively increase cardiovascular risk.

When Menopause Symptoms Could Signal A Heart Problem

Not every symptom during perimenopause is cardiac. Hot flashes, night sweats, sleep disturbance, anxiety and palpitations are common. However, new, severe or unusual symptoms deserve attention—particularly in women who have cardiovascular risk factors.

Chest discomfort is one symptom that should never automatically be attributed to menopause. Women may experience coronary disease differently from the classic crushing chest pain often described in men. Pressure, tightness, burning or discomfort in the chest, upper abdomen, back, jaw or arms may occur. Breathlessness, unusual fatigue, nausea, sweating or light-headedness can also accompany cardiac problems.

Palpitations And Irregular Heartbeats: When To Seek Help

Similarly, repetitive palpitations should not simply be labelled as hormonal. Perimenopausal fluctuations, stress, poor sleep and hot flashes can increase awareness of the heartbeat, but persistent rapid or irregular heartbeats, particularly when associated with dizziness, fainting, chest discomfort or breathlessness, warrant evaluation.

Increase in Blood pressure is another important warning sign. Hypertension is often silent, and women may discover it incidentally during this period. Repeated elevated readings should be assessed rather than attributed to stress.

Oestrogen influences the endothelium—the inner lining of blood vessels—and contributes to healthy vascular function. During the menopausal transition, hormonal fluctuations and eventual oestrogen decline occur alongside changes in lipid metabolism and body composition.

LDL cholesterol may rise, while HDL and triglyceride patterns can also change. Fat distribution often shifts towards the abdomen, even without a dramatic change in overall body weight. Muscle mass may decline and insulin resistance can increase.

Blood pressure may also rise with age. Sleep disruption, reduced physical activity, stress and changes in diet can further compound these effects.

It is important, however, not to think of menopause as a single switch that suddenly transforms a woman from low-risk to high-risk. Traditional risk factors like obesity, diabetes, smoking etc can increase the risk profile. Menopause is better understood as a period when existing risk factors may become more apparent or begin to accelerate.

Prevention should begin before menopause

The menopausal transition provides an excellent opportunity for a cardiovascular “health audit.”

Know your numbers. Blood pressure, fasting glucose or HbA1c, lipid profile and weight/waist circumference should be assessed according to individual risk. A woman with diabetes, hypertension, kidney disease, premature menopause or a strong family history of premature coronary disease may require more intensive assessment.

Keep moving. Regular aerobic activity combined with resistance training is particularly valuable. Brisk walking, cycling, swimming or similar activities can be complemented by strength training two or more times a week. Physical activity helps control blood pressure, glucose, weight and cholesterol while preserving muscle mass.

Pay attention to diet. A heart-healthy dietary pattern should emphasise vegetables, fruits, legumes, whole grains, nuts, seeds and appropriate sources of protein, while limiting highly processed foods, excess sugar, refined carbohydrates, trans fats and excessive salt. Alcohol should be limited.

Do not smoke. Smoking substantially increases cardiovascular risk, and stopping at any age provides meaningful benefit.

Protect sleep and manage stress. Insomnia and night sweats are common during perimenopause, but persistent sleep deprivation can adversely affect blood pressure, glucose regulation, appetite and overall cardiovascular health. Treating significant sleep problems is therefore part of cardiovascular prevention—not simply improving.

Menopausal hormone therapy (MHT) should not be viewed as a treatment for preventing heart attacks. Its cardiovascular effects depend on factors such as age, timing relative to menopause, the formulation used, route of administration and a woman’s underlying cardiovascular and thrombotic risk.

For women with troublesome menopausal symptoms, the decision about MHT should therefore be individualised after discussing benefits, risks and alternatives with an appropriately qualified clinician. Hormone therapy should not be started solely for cardiovascular protection.

A new perspective on menopause

Perhaps the most important message is that perimenopause should not be regarded simply as a collection of symptoms to be endured. It is also an opportunity to identify cardiovascular risk.

The hormonal transition is natural. Cardiovascular disease is not inevitable. Recognising this window as an opportunity for prevention can help women enter the postmenopausal years with a healthier heart—and with a clearer understanding that caring for cardiovascular health is an essential part of healthy ageing.
