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.
It is crucial to understand the relationship between diabetes and hypertension, and recognise the signs that may indicate they are interconnected. (Photo credit: AI generated)
In a country where diseases have become a daily topic of discussion, hypertension is gradually increasing behind closed doors. Also referred to as “the silent killer”, this ailment is notorious for making its presence known without symptoms, unlike many health conditions. By the time it is discovered, it may have already begun to affect vital organs.
One of the most prevalent comorbidities of hypertension is diabetes; together, the two create a difficult combination of chronic conditions affecting a patient's overall health. Diabetes causes high blood glucose (sugar) levels that, over time, damage blood vessels by reducing their ability to stretch or expand. When combined with the pressure caused by hypertension, these already compromised blood vessels can deteriorate rapidly, resulting in further damage.
The combined effects of diabetes and hypertension significantly increase the risk of heart-related complications, such as enlargement of the heart muscle, a reduced ability of the heart to pump blood effectively, and heart failure. Thus, the two conditions create a vicious cycle and emphasise the need for prompt diagnosis and treatment.
According to Dr Ameet Soni, AVP Medical Affairs, CORONA Remedies, “Hypertension and diabetes mellitus (DM) are two of the most common cardiometabolic disorders, often occurring together, and each exacerbates the impact of the other. When combined, these conditions significantly increase the risk of complications such as cardiovascular, cerebrovascular, and renal damage, particularly when symptoms are not identified early or when treatment adherence is inadequate. Minimising the risk of these complications depends on early identification, proactive risk assessment before diagnosis, and long-term adherence to treatment regimens for controlling blood glucose levels and blood pressure.”
According to Dr Manoj Chawla, Diabetologist, P.D. Hinduja Hospital and MRC, Khar, Mumbai, “These diseases are also termed ‘silent partners’, indicative of both their association and the silent damage they cause to bodily functions. The connection between these diseases in India is quite common owing to several factors, including a sedentary lifestyle, poor nutrition, obesity, excessive stress, and a lack of proper diagnosis. Individuals suffering from diabetes have twice the risk of developing hypertension compared with healthy individuals. Since both diseases are asymptomatic in many cases, patients may only discover them when complications arise. Early diagnosis of hypertension and diabetes is therefore vital. Tests such as blood pressure and blood glucose monitoring, weight management, proper nutrition, exercise, adequate sleep, and stress management all help to prevent these risks.”
Early detection and intervention are key to managing both conditions and reducing the risk of complications. If you are experiencing any of the symptoms mentioned above or have a family history of either condition, it is vital to consult your healthcare provider. Regular screenings, lifestyle modifications and adherence to prescribed treatments can help control both hypertension and diabetes, improving your quality of life and preventing long-term complications.

Parkinson’s disease is characterized by slowness of daily activities, rigidity, and tremors with gait issues, commonly seen after the age of 45-50 years.
It is two times more common in men than women, though clinical features, response to the treatment, and prognosis are different in women as compared to men. From subtle early signs to how the condition develops over time, gender can shape the Parkinson’s journey in important ways.
Women usually experience Parkinson’s disease at a later age, but with faster progression of symptoms as compared to men. There is a need for more research in this space; however, we will try to shed light on these differences in Parkinson's trajectories in men and women based on available evidence.
Estrogen, a group of primary female sex hormones, is neuroprotective and protects dopaminergic neurons in women; women also have a higher baseline reserve of dopaminergic neurons. Hence, Parkinsonism is less common in women.
In the post-menopausal period, once this estrogen-related neuroprotective effect disappears, Parkinson’s symptoms progress rapidly. Motor symptoms emerge later in women with tremors, rigidity, and gait disturbances being more common and severe. Freezing of gait and postural instability with falls are more common in women.
Non-motor symptoms like pain, fatigue, autonomic disturbances, sleep disorders, constipation, and mood disorders, including depression and anxiety, are more common and severe in women. Men with Parkinson’s disease have worse general cognitive abilities; however, women have worse visuospatial abilities.
Women with Parkinson’s receive less social support, lower quality care, attend medical appointments alone, and report more psychological stress. Women have a lower body mass index and higher bioavailability of levodopa, which makes them more susceptible to the side effects of levodopa, such as motor fluctuations and dyskinesia, which entail involuntary movements like fidgeting and writhing.
There is a clear need for personalized and tailored treatment. The different and distinctive clinical features in women, like later onset, higher tremors and rigidity, higher dyskinesia and motor fluctuations from drugs, and worse non-motor symptoms, require tailored, sex-specific treatment strategies rather than a “one-size-fits-all” approach.
Clinicians must give importance to the screening and management of non-motor symptoms in women, which are the main factors of their decreased quality of life. Women with this ailment go through longer delays in diagnosis and less access to specialists, highlighting a need for better healthcare access for women.

While HPV vaccines are most known for preventing cervical cancer, a top US doctor says they can also help curb the rising incidence of head and neck cancers.
According to Mikkael A. Sekeres, Chief of the Division of Hematology and Professor of Medicine at the Sylvester Comprehensive Cancer Center at the University of Miami, Human papillomavirus (HPV) — the same sexually transmitted virus that can infect the genital area and lead to cervical cancer — is now the greatest risk factor for head and neck cancer.
Writing in The Washington Post, Sekeres noted that HPV accounts for about 30 per cent of oropharyngeal cancer worldwide.
HPV is believed to be responsible for the recent rise in head and neck cancers, which include malignancies affecting the mouth and throat (oral cavity and pharynx), voice box (larynx), sinuses and nasal cavities, and salivary glands.
Sekeres said the US records about 60,000 new cases of head and neck cancers each year, while the global incidence is expected to rise by 30 per cent by 2030.
The expert noted that men develop oral cavity and pharynx cancers at approximately 2.5 times the rate of women.
Major risk factors include:

The Centers for Disease Control and Prevention (CDC) estimates that the high-risk HPV subtypes most associated with head and neck cancers are detectable in the mouths of 4 per cent of adults aged 18 to 69.
While a pap test detects early-stage cervical cancer in women, no such test exists for penile, anal, or head and neck cancers in men, which can worsen their survival rate.
Thus, Sekeres said: “The best way to prevent the most common types of HPV is through vaccination, with two doses of the vaccine recommended for children at age 11 or 12, or starting as early as 9 years and up to age 26 for those who missed it as a child".
He noted that although the vaccine is approved for use up to age 45, it is generally less beneficial after age 26 because many individuals may have already been exposed to HPV. However, doctors can help determine whether vaccination may still be beneficial for adults.
Earlier this year, the European Cancer Organization also urged broader HPV vaccination regardless of gender.
“HPV affects everyone, regardless of gender. It can lead to cancers of the cervix, mouth and throat, anus and penis. This is why universal protection is so important,” the organization said in a social media post.

A 2026 study published in JAMA Oncology found that boys and men who received the HPV vaccine between the ages of 9 and 26 were nearly 50 per cent less likely to develop cancers of the head and neck, esophagus, anus, or penis.
The findings, based on data of more than 510,000 boys and men, highlight the importance of vaccinating all children and adolescents against HPV, said Taito Kitano, first author of the study and a researcher at Nara Prefecture General Medical Center in Japan.
“Children, adolescents, parents and health care workers should be more informed about the expected benefits of the HPV vaccine, not just cervical cancer,” Kitano said.
