A new report published in The Lancet Diabetes & Endocrinology challenges the conventional definition of obesity, and urges a shift from the reliance on Body Mass Index (BMI) to a more nuanced approach. This is supported by over 50 global medical experts. The report also recommends splitting the term "obesity" into two categories: "Clinical obesity" and "Pre-clinical obesity". This aims to improve diagnosis and treatment for over a billion people worldwide living with obesity.

Clinically Obese

This applies to individuals whose obesity has progressed to a disease state, manifesting in organ damage, heart disease, type 2 diabetes, or other health complications. These individuals could also experience symptoms like breathlessness, joint pain, or impaired daily functioning. Treatment also involves medical interventions, including weight-loss medications or surgery.

Pre-Clinic Obese

Whereas the term "pre-clinic obese" refers to those who are overweight but not yet exhibiting health issues. While they may be at risk of developing obesity-related conditions, their organ function and overall health remain intact. What they need is preventive care, which includes dietary guidance, counselling, and regular monitoring to avoid and reduce future health risks.

What does the study say?

The study, led by Professor Francesco Rubino from King's College London emphasizes that obesity is not one-size-fits-all condition. This means it should rather be treated as a spectrum as some individuals maintain normal organ function despite being classified as obese. There are others who may face severe health complications too. However, the current method of calculating obesity based on BMI often leads to misdiagnosis or inadequate care.

The report also states that BMI, while is useful for analyzing population trends, is a flawed unit of measuring individual health. Therefore, there is a need to redefine obesity, and healthcare professionals can provide more precise care by distinguishing those who need immediate medical intervention and those who require preventive strategies.

Limitations of BMI, Why It Falls Short?

BMI is used to classify individuals as underweight, healthy weight, overweight, or obese based on their height and weight. It is calculated by dividing weight in kilograms by health in meters squared. However, there are reasons while it falls short.

•Muscle vs Fat: Athletes or muscular individuals often have high BMIs despite the low body fat

•Fat Distribution: BMI does not measure fat around the waist or organs, which could be more dangerous to one's health.

•Individual Health Variation: It also overlooks the specific health conditions such as heart diseases or diabetes, or any other, while evaluating a person's category in terms of weight.

Scope Of Study

By redefining obesity, the study could transform the approach to diagnosis and treatment. It can focus on individual health risks rather than BMI alone. Healthcare providers can also offer tailored care. This also will ensure hat weight-loss medications like Wegovy or Mounjaro are prescribed only to those who genuinely require it.

As per Professor Louise Baur from the University of Sydney, a Children's obesity expert said that this redefinition allows both adults and children to receive more appropriate care while reducing over-diagnosis and unnecessary treatments.

The World Health Organization (WHO)'s Montreal meeting focused on wearable technology like smartwatches and activity trackers as a reliable source of health tracking. The meeting discussed that wearables could in fact generate objective real-time data, which helps governments design targeted and evidence-based health interventions.

Physicians in the Montreal meetings discussed that wrist-worn devices are more reliable than traditional self-reported surveys. This is because the self-reported surveys could underestimate the levels of physical inactivity.

“Metrics such as step count, moderate-to-vigorous physical activity and sedentary time directly correlate with cardiovascular disease, diabetes and mental health outcomes. Having population-level data allows for early and preventive strategies,” said Dr Venkat Nani Kumar, consultant in internal medicine.

WHO Montreal Meeting: How Have Doctors Reacted The Shift To Wearables?

Doctors in India have welcomed this shift to wearable devices as a better way to generate data and make policies. Dr Kiran Madhala, professor at Gandhi Medical College, Secunderabad, said WHO’s shift reflects rapid advances in artificial intelligence and digital health tools, calling it a progressive step towards improved monitoring of physical activity worldwide.

City-based doctors also underlined the need for inclusive validation of devices. “Wearables must recognise varied movement patterns and step equivalents, especially in ageing populations,” a physician said, while stressing the importance of data privacy and ethical use of health information.

WHO Montreal Meeting: What Are Wearable Health Devices?

As per a 2022 study published in JMIR MHealth and UHealth, wearables refer to devices that are worn by individuals. In health care field, they assist with individual monitoring and diagnosis. Wearables are “seamlessly embedded portable computers...worn on the body," notes another 2018 study published in Telematics Informatics.

A 2018 study published in the journal Sensors noted that wearable health devices are increasingly helping people to better monitor their health status both at an activity/fitness level for self health tracking and at a medical level providing more data to clinicians with a potential for earlier diagnostic and guidance of treatment.

Blood Pressure Monitor

This is a blood pressure monitor that consists of a cuff that is placed in upper arm with a digital display that provides real time reading of systolic and diastolic blood pressure.

Glucose Monitoring Device

This device estimates your glucose levels in every few minutes. It can be worn in upper arm, with a phone sensor connected to measure readings. It also includes real time glucose alarms to make informed decisions.

Wearable ECG Monitor

ECG patches are interconnected with smartphones, where one can see their readings. They not only measure electrocardiograms, but also detect any abnormalities.

Fitness Tracker

Smartwatches or fitbits that could be worn on your wrist. They help track real time data of your health, steps, heart rate, calorie consumptions, and even sleep patterns. It can also help keep track of oxygen levels.

Integrated Activewear

These activewears come with microscopic sensors to safeguard wearer's body or assist them in reaching their fitness objective.

Epilepsy affects more than 15 million people in India, yet it remains one of the most misunderstood neurological conditions. Despite being a treatable brain disorder, fear, stigma and long-standing myths continue to delay diagnosis and care, especially in smaller towns and rural areas. Doctors say this lack of awareness often causes more harm than the condition itself.

According to the World Health Organization (WHO), nearly 50 million people worldwide live with epilepsy, making it one of the most common neurological disorders. The WHO also estimates that up to 70 per cent of people with epilepsy can live seizure-free if properly diagnosed and treated. Yet, in low- and middle-income countries, almost three-fourths of patients do not receive the treatment they need.

What Really Happens During a Seizure

Dr Madhukar Bhardwaj, Director and Head of Neurology at Aakash Healthcare, explains that epilepsy occurs due to a sudden disturbance in the brain’s electrical activity. “A seizure happens when the brain’s electrical signals stop working normally for a short time,” he says.

This can cause a wide range of symptoms, from jerking movements and falling unconscious to staring spells or brief confusion. “Some seizures last just a few seconds and may go unnoticed, while others can be severe,” Dr Bhardwaj adds.

Breaking Dangerous and Persistent Myths

Despite medical clarity, myths around epilepsy remain deeply rooted. Dr Bhardwaj points out that many people still believe epilepsy is caused by ghosts, black magic, or divine punishment. “Others think it spreads by touch or that people with epilepsy cannot study, work or get married,” he says.

One of the most dangerous misconceptions is putting an object into a person’s mouth during a seizure. “This is completely false and can seriously injure the patient,” Dr Bhardwaj warns. Doctors stress that epilepsy should be treated like any other chronic condition, such as diabetes or high blood pressure, not as a social taboo.

Understanding the Real Causes of Epilepsy

Dr Neha Kapoor, Associate Director and Head of Neurology at Asian Hospital, says epilepsy does not have one single cause. “In many cases, we are unable to find an exact reason,” she explains. However, known causes include genetic factors, head injuries from accidents, brain infections like meningitis, strokes, and other forms of brain damage.

In children, epilepsy may result from lack of oxygen at birth or abnormal brain development before birth. Dr Kapoor also clarifies a common misunderstanding: “Stress, lack of sleep, and alcohol can trigger seizures, but they are not the root cause of epilepsy.”

Why Epilepsy Often Goes Undiagnosed

Not all seizures look dramatic, which leads to frequent delays in diagnosis. “Not all seizures involve shaking,” says Dr Praveen Gupta, Chairman at Marengo Asia International Institute of Neuro and Spine (MAIINS). “Some look like daydreaming or sudden confusion, which is why epilepsy is often missed.”

Dr Gupta notes that many patients reach specialists very late due to fear and misinformation. “With timely treatment, most people with epilepsy can live completely normal lives,” he says.

Advanced Treatment and Surgical Options

Nearly 70 per cent of epilepsy patients can control seizures with regular medication, according to doctors. For those who do not respond to medicines, known as drug-resistant epilepsy, advanced treatment options are now available in India.

“Epilepsy surgery is being used successfully,” Dr Gupta explains. “We carefully identify the part of the brain causing seizures and treat it safely. This can greatly reduce or even stop seizures.” He adds that modern surgical and neuro-robotic techniques are changing outcomes and offering renewed hope.

Addressing Sexual Health and Quality of Life

Epilepsy can also affect aspects of life that are rarely discussed, including sexual health. Dr Vineet Malhotra, Principal Consultant at SCM Healthcare, says seizures, stress and some anti-seizure medications may impact energy levels, hormones and sexual desire in men.

“However, these issues are manageable,” Dr Malhotra says. “With counselling, lifestyle changes and medication adjustments, patients can lead healthy, active and fulfilling lives.”

Doctors agree that awareness, early diagnosis and breaking myths are key to ensuring epilepsy is treated as what it truly is, a manageable medical condition, not a social label.

Atrial fibrillation (AFib) is an irregular and often very rapid heart rhythm, also called an arrhythmia and can create blood clots in the heart, which can increase your risk of having a stroke by five times.

When a person has AFib, the normal beating in the upper chambers of the heart (the two atria) is irregular and blood doesn't flow as well as it should from the atria to the lower chambers of the heart (the two ventricles).

In this case, the risk of developing blood clots in your heart increases, which can not only cause a heart attack but also damage vital organs such as your brain. An AFib may happen in brief episodes, or it may be a permanent condition.

Common symptoms include palpitations (the feeling that your heart is racing, pounding, fluttering or like you have missed heartbeats), chest pain, finding it harder to exercise, tiredness, shortness of breath, dizziness or feeling faint.

The death rate from AFib as the primary or a contributing cause of death has been rising for more than two decades.

Over 454,000 people with AFib are hospitalized in the US each year, out of which 158,000 die of the cause. It is estimated that 12.1 million people in the US will have AFib in the US will have AFib by 2050.

Who Is At Risk Of Having AFib?

• Advancing age.
• High blood pressure.
• Obesity.
• European ancestry.
• Diabetes.
• Heart failure.
• Ischemic heart disease.
• Hyperthyroidism.
• Chronic kidney disease.
• Moderate to heavy alcohol use.
• Smoking.
• Enlargement of the chambers on the left side of the heart.

Treatment for AFib includes medications to control the heart's rhythm and rate, therapy to shock the heart back to a regular rhythm and procedures to block faulty heart signals.

A person with atrial fibrillation also may have a related heart rhythm disorder called atrial flutter. The treatments for AFib and atrial flutter are similar.

How To Improve Your Heart Health

Experts recommend following the below to reduce yor risk of stroke or developing AFib and maintaining heart health:

• Don't smoke or use tobacco.
• Aim for at least 150 minutes of moderate physical activity or 75 minutes of vigorous physical activity (or an equal combination of both) each week. Eat a heart-healthy diet.
• Stay at a healthy weight.
• Get quality sleep.
• Manage stress levels
• Get regular health screening tests.
• Eat a fiber, nuts and fish-rich diet
• Limit salt intake
• Reduce saturated fat intake
