Using BMI To Classify People As Obese Is Flawed Say Experts

Updated Jan 16, 2025 | 11:57 AM IST

SummaryBMI 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.
BMI Not the right way to measure obesity

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.

From Winter Dryness To Summer Sweat: How to Prevent Seasonal Dandruff Flare-Ups

Updated Apr 2, 2026 | 10:00 PM IST

SummaryWith the right proactive approach, seasonal changes do not have to mean persistent dandruff concerns. A balanced scalp care routine combined with effective active ingredients can help maintain scalp health and reduce visible flakes throughout the year.

As winter transitions into warmer summer months, many people notice a sudden worsening of dandruff. During colder months, dandruff often appears as dry, fine flakes due to scalp dryness. However, as temperatures rise and humidity increases, dandruff can become oily and sticky because of increased sweating and sebum production. This seasonal shift highlights that dandruff is not limited to a particular time of year; rather, changes in climate can disrupt scalp balance and trigger flare-ups. Dr. Anupriya Goel, MBBS, MD, DPD (UK) – Dermatology, answered this for us.

Why does dandruff recur?

Many people struggle to understand why dandruff keeps recurring. It is often treated as a temporary cosmetic concern, but in reality, dandruff is a chronic scalp condition that requires consistent care and appropriate treatment. The primary cause of dandruff is a yeast called Malassezia globosa, which naturally resides on the scalp. This microorganism feeds on sebum (the natural oils produced by the scalp). As it breaks down these oils, it releases by-products that can irritate the scalp, leading to inflammation, itching, and visible flaking.

Seasonal factors further aggravate this process. In winter, cold air, low humidity, indoor heating, and frequent hot showers can strip the scalp of its natural moisture and weaken the skin barrier, resulting in dryness and flaking. In contrast, summer brings increased sweat and oil production. The combination of humidity, sweat, and sebum creates an ideal environment for Malassezia to multiply, which can worsen dandruff symptoms.

What are the external factors responsible for dandruff?

Environmental factors such as pollution can also settle on the scalp and contribute to irritation. In addition, daily habits like wearing helmets for long hours, tying up damp hair, or not cleansing the scalp regularly can further disrupt scalp health. The transition period between seasons is often the most challenging, as the scalp has limited time to adapt to changing environmental conditions.

Because dandruff is often mistaken for a temporary issue, many people rely on occasional treatments or home remedies. However, effective management typically requires regular scalp-focused care using clinically proven active ingredients.

Treating dandruff

One such ingredient commonly used in anti-dandruff formulations is Piroctone Olamine, an antifungal agent that helps control the growth of Malassezia on the scalp. By reducing fungal proliferation, it helps address the underlying cause of dandruff and can assist in decreasing flaking, itching, and scalp irritation. It also helps cleanse the scalp by removing excess oil and buildup while being relatively gentle on the hair and scalp.

For optimal results, individuals experiencing recurrent dandruff may benefit from incorporating an anti-dandruff shampoo containing Piroctone Olamine into their regular hair care routine. Consistent use is important for maintaining scalp balance. During periods of increased sweating, such as in hot and humid weather, washing frequency may be increased as needed. Maintaining hygiene practices such as regularly cleaning helmets, pillowcases, and hair accessories can also help minimise recurrence.

In addition to controlling dandruff, well-formulated shampoos containing Piroctone Olamine are often combined with conditioning and moisturising ingredients that help maintain hair softness and scalp comfort while supporting long-term scalp balance.

Why Autism In Women Is Often Overlooked And Misdiagnosed

Updated Apr 2, 2026 | 06:30 PM IST

SummarySubtle presentation, masking behaviors, gender bias, and overlap with other conditions cause the overlooking of autism in women. Clinicians and the general public need to be more aware of autism in women for timely diagnosis and necessary support.

Autism in women is not often entirely recognized because this disorder does not always have to correspond to the “classic” picture characteristic of males.

The diagnosis is based on a male criterion with such behavior as obvious withdrawal from a group, overtly displayed repetitive behaviour, and limited interests. There can be mild social deficit or internalized anger and frustration that can pass unnoticed in clinical practice.

The Art of Masking

One of the most significant reasons behind underdiagnosis is masking (also called camouflaging). Masking is one of the most significant reasons for underdiagnosis. This is helpful in masking but also covers or conceals essential symptoms.

Masking causes mental exhaustion, anxiety, and burnout, but it does not address the underlying autism and leaves it undiagnosed.

Stereotypes And Gender Bias

There is a strong societal stereotype that autism is a “male condition”. This bias is felt by parents, teachers, as well as health care professionals.

Sex bias is evident in that boys get referred for evaluation early. Girls are often tagged “shy,” “sensitive,” and “introverted.”

Their struggles are normalized instead of being explored for any issues. Gender bias is a significant contributor to delayed or wrong diagnosis.

Different Interests, Less Suspicion

A restricted interest is another hallmark of autism, but in women, it tends to be more socially acceptable. Their interests conform to the norms of society; they do not predispose clinical suspicion as opposed to more masculine interests like mechanical systems or numbers.

Overlap With Other Conditions

Autism in women being misdiagnosed as other psychiatric disorders is due to symptom comorbidity. Some of the common misdiagnoses are:

  • anxiety disorders,
  • major depressive disorder,
  • borderline personality disorder,
  • eating disorders.

In many cases, these are secondary to autism as a result of years of living with undiagnosed autism.

Social Expectations And Conditioning

From an early age, girls are often conditioned to be socially attentive, empathetic, and compliant. This societal conditioning pushes autistic girls to adapt and hide their difficulties.

These may include forcing themselves into socializing. Fitting in is deemed more important than comfort. They end up creating coping mechanisms that mask their difficulties.

While this may benefit outward functioning, it postpones the recognition of underlying neurodevelopmental differences.

The Consequences of Late Diagnosis

Delayed diagnosis or missed diagnosis has the following effects:

  • Chronic mental illness
  • Low self-esteem
  • Confusion about identity
  • Inadequate support services
However, a correct diagnosis, even if received in adulthood, can be transformative, offering clarity, validation, and access to appropriate interventions.

Endometriosis Taught Me To Always Listen To My Body, Says Model Padma Lakshmi

Updated Apr 2, 2026 | 05:00 PM IST

The World Health Organization estimates that 10 percent (190 million) of reproductive-age women worldwide suffer from endometriosis.

The chronic and complex menstrual disease that affects many women is characterized by severe pain during menstruation, heavy menstrual bleeding, chronic pelvic pain (pain that does not go away when the menstrual cycle ends), infertility, and abdominal bloating and nausea.

The incurable condition poses a significant challenge to women as it affects their personal and professional lives, relationships, and fertility, among others, due to persistent pain and fatigue.

The diagnosis also gets delayed, as endometriosis is often confused with PCOS, or Polycystic Ovary Syndrome, due to some overlapping symptoms like irregular menstrual periods. The symptoms may continue to persist or recur after treatment is initiated.

In a powerful statement resonating with millions worldwide, Indian American author and television host Padma Lakshmi has shared her experience with the condition.

Opening about her personal battle with endometriosis, the 55-year-old, Co-founder of Endometriosis Foundation of America, said that the condition made her understand how strong she is and called for greater awareness and self-advocacy among women.

"Endometriosis has taught me that I should always listen to my body. Pain is your body's way of telling you something is wrong,” said Lakshmi, in a media post on social media platform Instagram.

"Through my struggles with endometriosis, I've learned that, actually, I have a very high threshold for pain, that I may be stronger than I know, but that I shouldn't always need to be,” PopSugar quoted her as saying.

Lakshmi noted that it is now her life's mission "to advocate for my own health, and also to advocate for all women with endometriosis."

What Is Endometriosis?

Endometriosis happens when tissue similar to the lining of the uterus grows outside the uterus. These tissues commonly develop on the ovaries, fallopian tubes, or the pelvic lining.

Endometriosis affects many women and can impact their daily lives, including their ability to work comfortably. Many women continue their professional responsibilities despite experiencing severe discomfort, fatigue, and pain.

Raising awareness about the condition and encouraging supportive workplaces can help women manage both their health and career more effectively.

Since it is a progressive disorder, timely intervention remains key to managing it. In many cases, women live with symptoms for several years before receiving the correct diagnosis, which can delay treatment and affect their quality of life.

Treating Endometriosis

Treatment is particularly based on the severity of symptoms. Women will be advised lifestyle modifications such as regular exercise, stress management, and an anti-inflammatory diet. Non-steroidal anti-inflammatory drugs may help reduce discomfort.

Hormonal therapies may also be used to control symptoms. Some women will be advised to undergo laparoscopy to remove endometriotic cysts.

Minimally invasive surgery can help remove lesions and restore pelvic anatomy, which may also improve fertility in some cases. In advanced cases, surgery can be recommended to women.
