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.
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.
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.
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.
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.

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.

People with hemophilia face an increased risk of poor bone health due to recurrent joint and muscle bleeds, joint damage and reduced physical activity. Experts told HealthandMe that preventing bleeds from childhood, alongside adequate nutrition, appropriate exercise and regular assessment, can help protect bone health throughout life.
Globally, an estimated 836,000 people have hemophilia, including approximately 284,000 with severe hemophilia. In India, the World Federation of Hemophilia (WFH) reported nearly 28,000 diagnosed and registered patients as of 2026, including more than 24,000 with Hemophilia A. However, the estimated prevalence could be as high as 1,36,000, suggesting many cases remain undiagnosed or misdiagnosed.
Childhood and adolescence are critical for building peak bone mass, making early intervention important for long-term musculoskeletal health, said health experts.
Hemophilia is an inherited bleeding disorder caused by a deficiency of clotting factor VIII (Hemophilia A) or factor IX (Hemophilia B). It primarily affects males, while women are often carriers.
Repeated bleeding into joints can cause chronic pain, joint damage, deformity and reduced mobility. Muscle bleeds can further restrict movement, limiting participation in physical activities that help maintain bone strength.
“Bone health begins in childhood, but protecting it is a lifelong commitment. In people living with hemophilia, recurrent joint and muscle bleeds, reduced physical activity and other risk factors can contribute to poor bone health and an increased risk of osteoporosis,” Dr. Varun Bafna, associate professor in the Department of Hematology at Chhatrapati Shahu Maharaj Government Medical College, Kolhapur, told HealthandMe.
Prophylaxis involves preventive treatment to reduce bleeding episodes rather than treating bleeds only after they occur. Regular factor prophylaxis can help prevent recurrent joint bleeds, preserve joint function and support mobility.
“Regular factor prophylaxis helps prevent repeated joint bleeds and preserve joint function. That protection can support mobility, an important contributor to bone health,” Dr. Hitha B, associate professor and haematologist in the Department of Medicine at Government Medical College, Kozhikode, told HealthandMe.
She advised patients to discuss breakthrough bleeding or difficulties accessing treatment with their healthcare team so their treatment plan can be reviewed.
Dr. Bafna said consistent prophylaxis can also support muscle strength and safer participation in physical activity.
“Prophylaxis is not just about preventing bleeding today; it is an important part of protecting long-term musculoskeletal health and quality of life at every age,” he noted.
Experts recommend an individualized approach based on age, joint health, mobility and other risk factors. Key measures include:
Hematologists, physiotherapists and other healthcare professionals can help patients and families integrate preventive treatment, rehabilitation, nutrition and appropriate physical activity into an individualized care plan.
Early intervention and consistent care can help preserve joint function, mobility and quality of life as people with hemophilia grow older.

A stroke rarely announces itself loudly. A sudden wobble, a blurry eye or a slightly lopsided smile is easy to ignore. But in a stroke, minutes decide how much of the brain survives.
On World Stroke Day, doctors want everyone to know one simple tool: BE FAST.
Dr. Abhinav Gupta, Director of Neurology at Sarvodaya Hospital, Greater Noida West, and Dr. Atampreet Singh, Senior Director and Head of the Institute of Neurosciences at ShardaCare, Healthcity, told HealthandMe, “Knowing the early warning signs of a stroke can shorten the road to full recovery,” they said.
The problem, they added, is that “a stroke’s symptoms can be easy to dismiss as minor inconveniences, like being tired or having weak muscles.”
BE FAST was developed by Intermountain Healthcare as an adaptation of the American Stroke Association’s FAST model, according to a Frederick Health handout. The doctors break it down like this:

Time is not a symptom. It is a reminder to hurry. Duke Health, citing the American Stroke Association, says to call for help even if the symptoms go away. Weill Cornell Medicine, citing the same group, says never to drive yourself to hospital.
The Frederick Health handout adds that you should note when the symptoms began. UChicago Medicine estimates that about 1.9 million brain cells die every minute in a stroke caused by a large blocked artery.
India’s biggest problem is delay in seeking medical treatment.
An ICMR study of 34,792 stroke cases at 30 hospitals between 2020 and 2022 found that only 5.3% of patients reached hospital within the first hour, according to South First. Nearly four in ten waited more than 24 hours. Down To Earth, reporting on a Lancet Neurology study, says India had over 1.25 million new stroke cases in 2021, up 51% since 1990.
If you see even one sign, don’t wait for the others. Call 112, India’s single emergency number, which also covers the 108 ambulance service, according to Factly. Say what you see and when it began.

Many people track their steps, sleep and heart rate with a precision that once seemed unusual. The feet behind those steps rarely get the same attention, hidden as they are inside shoes all day.
A crack, an ache or a patch of numbness is easily put down to the weather, age or an ill-fitting pair of sandals. Yet some complaints reach a clinic only after they begin to interfere with everyday life.
Cracked heels are a good example, because they are so common that most people treat them as a cosmetic matter and reach for a moisturiser. That is usually reasonable, although a deep fissure that bleeds or keeps reopening gives bacteria a way into the skin and is worth having examined.
Heel pain often has a musculoskeletal cause and tends to respond to rest and supportive footwear, but pain that lingers for weeks points to something more specific. Numbness gives the least warning of all, since it can arise from nerve compression, poor circulation, nutritional deficiencies or diabetes, and because it does not hurt, an injury can go unnoticed for days.
When a wound does develop, understanding whether it is actually healing becomes just as important as recognising the early warning signs. Researchers who monitor wounds over time know that appearance alone does not always tell the full story.
A 2025 case report in the Journal of the Foot & Ankle followed two adults with long-standing diabetes and neuropathic plantar ulcers for twelve weeks, with wound area quantified by digital planimetry. One wound, treated with a graft of decellularised human dermis, shrank by 80 percent by week four and had fully epithelialised by week eight.
The other, managed with gauze-based moist wound care, reduced by 7.8 percent at week two, grew by 21.6 percent between weeks three and five, and reached a 68.6 percent reduction by week twelve without closing. No adverse events were recorded in either patient during the twelve weeks.
The report is descriptive, and two patients cannot settle questions about any treatment. The lesson that carries beyond the clinic is more modest, since progress is easier to judge when it is tracked against a timeline.
For readers, the message is to pay attention not just to how serious a symptom looks, but also to how long it has lasted and whether it is changing. Cracks that repeatedly reopen, persistent heel pain and spreading numbness deserve medical attention.
For people with diabetes, any new foot wound should be assessed promptly rather than waiting to see whether it improves on its own.
