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), notes that 36% of world's rabies deaths come from India, and a 2024 Lancet study notes that the country accounts for over one-third of global rabies deaths. When we spoke to Dr Aniket Mule, Consultant Internal Medicine at KIMS Hospital, Thane, he said that it is not just dog bites that lead to rabies, but it could happen from any rabies-susceptible animal. The first line of defense after you clear your wound immediately is to get the rabies vaccine. "Rabies vaccination is required for bites or scratches from any rabies-susceptible animal, including cats, monkeys, bats, foxes, and other wild mammals," he pointed out. As the country's apex court ruled and issued directives on stray dogs, focusing on public safety by ordering their removal, global health organizations, including WHO point out that this is not the right way to deal with rabies issue. Comprehensive methods including evidence=based strategies that center on mass dog vaccination is the key to the problem.

However, before this could be implemented, here's what you should know about dog bites and rabies.

What To Do After A Dog Bites Or Scratches You?

Dr Mule points out that even when there are minor scratches, without bleeding, you must get a rabies shot. "Rabies can be contracted through broken skin. Such exposures still require medical evaluation and, in most cases, rabies vaccination."

What Should One Do Immediately After Being Bitten Or Scratched?

• Wash the wound immediately for at least 15 minutes with soap and running water
• Apply an antiseptic such as povidone-iodine
• Do not apply home remedies like turmeric, chili or oil
• Seek medical care promptly for rabies vaccination and possible immunoglobin

Dr Mule points out that the rabies vaccine should be started as soon as possible. "Ideally within 24 hours of a bite or scratch. However, even if there is a delay of days or weeks, vaccination should still be started immediately as rabies has a variable incubation period," he says.

After the bite, the immediate medical attention involves rabies post-exposure prophylaxis or PEP, and with a tetanus booster. Some rabies vaccines also use saline water as the diluent to reconstitute the freeze-dried powder before injection.

The temperature of the vaccine matters. "Rabies vaccines are temperature-sensitive and must be stored between 2°C and 8°C. Exposure to heat or freezing can reduce vaccine potency. Poor cold-chain maintenance is a known reason for vaccine failure in rare cases," points out the doctor.

Cases Of Rabies Coming Back After Vaccination Course Has Been Done

Dr Mule points out that in order to avoid such things happening, one must ensure immediate wound washing, timely vaccination, and correct use of Rabies Immunoglobulin or RIG. Rabies can come back if these following things occur:

• Delay in starting vaccination
• Failure to administer Rabies Immunoglobulin (RIG) in severe (Category III) exposures
• Improper wound cleaning
• Incorrect injection site (gluteal region)
• Poor vaccine storage (cold-chain failure)

Dr Mule points out that the vaccine should be given intramuscularly in the deltoid or upper arms for adults, as gluteal or buttock injections could lead to inadequate absorption and reduce effectiveness.

How Many Doses Should One Get?

• For someone not previously vaccinated, the current standard is 4 doses on days 0, 3, 7, and 14 (intramuscular schedule).
• In some government programs or intradermal schedules, 3–4 doses may be advised.
• Previously vaccinated individuals require only 2 booster doses (days 0 and 3).

The exact schedule depends on vaccination history and the protocol followed.

Winter in India is often associated with sardio ke laddoo, but also with increasingly sedentary lifestyle, worsening air pollution, all of which leads to more time spending home than to going out, taking a stroll, working out and more. This is why as winter sets in, India also sees a quiet but consistent rise in non communicable diseases, or NCDs, conditions that now account for nearly two thirds of all deaths in the country. Heart disease, diabetes, thyroid disorders, fatty liver disease and arthritis continue to rise across age groups, driven by sedentary lifestyles, dietary excess and delayed diagnosis.

Winter can further aggravate these risks. Physical activity drops, calorie dense foods become routine, sunlight exposure reduces and metabolism changes. Studies and hospital data in India have repeatedly shown that heart attacks and strokes tend to spike during colder months. Blood vessels constrict, blood viscosity increases and cholesterol levels often rise. Blood sugar control also becomes more challenging, while joint pain and stiffness worsen for many.

Dr. Mayanka Lodha Seth, Chief Pathologist at Redcliffe Labs, says the problem is not seasonal food but seasonal neglect. “Traditional winter foods are not harmful on their own. The real risk comes from consuming them without understanding what is happening inside the body,” she explains. “Winter tends to mask symptoms while quietly worsening internal imbalances.”

With India already home to over 100 million people living with diabetes and a similar number estimated to be prediabetic, preventive testing becomes crucial. Doctors recommend five key tests that can offer a clearer picture of health before winter indulgence begins.

Blood Sugar Levels

Diabetes is one of the fastest growing NCDs in India, and a large proportion of cases remain undiagnosed. Winter diets high in sugar and fat can trigger frequent glucose spikes. Testing fasting blood sugar and HbA1c helps identify early risk and prevents long term complications affecting nerves, kidneys and the heart.

Lipid Profile

High cholesterol is a major contributor to cardiovascular disease, which remains India’s leading cause of death. Reduced activity in winter often pushes lipid levels higher. A lipid profile helps assess heart risk and guides dietary and lifestyle moderation before damage sets in.

Liver Function Test

Non alcoholic fatty liver disease is increasingly common in India, even among younger adults. Excess sugar and fat intake during winter can worsen liver fat accumulation. Early liver testing can flag reversible changes before they progress to chronic liver disease.

Thyroid Function Test

Thyroid disorders affect millions in India, especially women, and often go unnoticed. Symptoms like weight gain, fatigue and cold intolerance are frequently brushed off as winter sluggishness. A simple thyroid test helps distinguish seasonal lethargy from hormonal imbalance.

Vitamin D and Vitamin B12 Levels

Vitamin D deficiency is widespread due to limited sun exposure in winter, while Vitamin B12 deficiency remains common because of dietary patterns. Both deficiencies are linked to low immunity, muscle pain, bone weakness and worsening joint discomfort.

Dr. Seth adds, “Preventive diagnostic testing allows people to make informed choices. It helps them enjoy winter foods in moderation without unknowingly worsening an underlying condition.”

As NCD related healthcare costs continue to rise in India, early testing offers both health and financial protection. Winter comfort does not have to come at the cost of long term health. Staying informed may be the most effective preventive step this season.

Flu season is hitting hard this year, and the symptoms could feel relentless. People are suffering from rising fever, hacking cough, blocked and stuffy nose and sore throat. While many people get relief from Tamiflu, which is a prescribed antiviral medication that is used to treat or even to prevent illness, there are other alternatives available too.

Dr Ari Brown, a Texas based pediatrician and the author of Baby411 book series told CNN health that one of the most common complaints that she gets to hear from Tamiflu is vomiting. A 2023 study published in the Pediatric Infectious Disease Journal notes that 18% of people experienced vomiting with Tamiflu, as compared to 5% with Xofluza, an alternative.

“I’ve also had a few pediatric patients experience moodiness with Tamiflu, which is reported in the literature,” she said.

Tamiflu is usually gives to treat flu in people ages 2 weeks and older and to reduce the chance of getting the flu in people 1 year and older. The medicine could be administered in both form, liquid and capsules and usually taken twice daily for five days straight. This is prescribed for when flu is to be treated. However, when used for prevention, it is typically taken once for 10 days.

What Are The Other Alternatives Available For Flu Treatment?

Xofluza: It is administered as a single dose tablet and is approved for ages 5 and older. This medicine can also be used to treat or to prevent the flu. While it costs nearly $200 for those without insurance, eligible patients can use coupons to lessen costs. Dr Brown points out that this medicine could have side effects like diarrhea and vomiting. However, the study aforementioned notes that for this, only 5% patients had vomiting symptoms, when compared with Tamiflu.

Dr Brown also said that Xofluza can stop viral shedding in one day, while Tamiflu could take up to three days. "Both antivirals will help reduce the duration of misery by couple of days," she pointed out.

Dr Brown also pointed out that overall, "Xofluza is rising in popularity over Tamiflu." “One dose. Fewer side effects. More insurances are covering the cost of it now and manufacturer coupon makes it less expensive than in previous years," she said.

Rapivab: This is another prescribed medication that is approved to treat flu. This could be administered for people ages 6 months and older. It has to be given by a health care provider, as it is given once as an intravenous infusion. It could cost up to $1,000 without insurance and most common reaction in adults is diarrhea.

Relenza: This flu medication is inhaled in powder form. It is administered through an inhaler device, which is to be used twice a day for five days straight. The prescribed drug is approved to treat flu in ages 7 and older and for preventative use, in ages 5 and older. It could cost about $90 without insurance.

It may have side effects like dizziness, allergic reaction, or irritation of the nose. It is not recommended for people who have breathing issues or have asthma.
