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.

As cervical cancer screenings ramp up across the world, a new JAMA study shows that a majority of women prefer clinic-based testing over at-home self-sampling tests in the US.

Researchers from the University of Texas MD Anderson Cancer Center, Houston studied 2,300 women with an average age of 45.5 years. Most were married or living with a partner (58.2 percent), had health insurance (91.9 percent), and had at least some college education (61.6 percent).

Out of those analyzed, over 60 percent preferred clinic-based testing, 20 percent preferred at-home self-sampling tests and over 18 percent were unsure. However, women who had experienced prejudice or discrimination in healthcare were nearly twice as likely to prefer at-home testing.

The study noted that out of the women who preferred at-home testing, nearly 55 percent said it was due to greater privacy, over 35 percent said it was because of a lack of time and over 33 percent noted it was due to fear of embarrassment.

Marginalized women, individuals with low income and individuals who do not trust the health care system were also more likely to prefer at-home self-sampling for cervical cancer screening or not know which option to choose.

To increase screening uptake, the researchers suggested that US officials should incorporate home-based self-sampling as an alternative to clinic-based testing, women’s education and empowerment should be enhanced and tailored interventions focusing on high-risk groups are needed to increase awareness and self-confidence in performing home-based self-sampling.

What Is Cervical Cancer?

Cervical cancer develops in a women's cervix (uterus opening) due to abnormal cell growth, primarily caused by persistent HPV infection, a common infection that's passed through sexual contact.

When exposed to HPV, the body's immune system typically prevents the virus from causing damage however, in a small percentage of people, the virus can survive for years and pave the way for some cervical cells to become cancerous.

Treatment involves surgery, radiation, and chemotherapy, with early detection significantly improving outcomes, though it remains a major cancer in low-income countries Cervical cancer can also be prevented through vaccination and regular screening (Pap/HPV tests).

Symptoms Of Cervical Cancer

Cervical cancer has no symptoms in the early days and therefore, is hard to detect until it has spread. However, the early-stage symptoms include:

• Vaginal bleeding after sex
• Vaginal bleeding post-menopause
• Vaginal bleeding between periods or unusually heavy/long periods
• Watery vaginal discharge with a strong odour or containing blood
• Pelvic pain or pain during intercourse
• Advanced Cervical Cancer Symptoms (when cancer has spread beyond the cervix)
• Painful or difficult bowel movements or rectal bleeding
• Painful or difficult urination or blood in the urine
• Persistent dull backache
• Swelling of the legs
• Pain in the pelvis or lower abdomen

Cervical Cancer: A Growing Crisis In India

As per the World Health Organization (WHO) Director-General Tedros Adhanom Ghebreyesus, about 42,000 new cases of cervical cancer is reported annually in India. This underscores the need for preventive measures such as vaccination and early screening. The country loses one women every eight minutes to cervical cancer.

The WHO Global Strategy to eliminate cervical cancer includes the 90-70-90 targets by 2030 -- vaccinating 90 per cent of girls against HPV, screening 70 percent of women, and ensuring treatment for 90 percent of those diagnosed with cervical disease.

In line with the global strategy to fight cervical cancer, Prime Minister Narendra Modi recently also launched a free HPV vaccination drive that will target health and well-being of adolescent girls in the country.

Union Health Minister JP Nadda has also announced that cervical cancer screenings using Visual Inspection with Acetic Acid (VIA) will now be available at Ayushman Arogya Mandirs and other health facilities for women between 30 and 65 years of age.

"Screening for cervical cancer is now available at 1,81,000 Ayushman Arogya Mandirs, also known as Health and Wellness Centers, across the country as a part of population based screening for early detection and treatment," said Nadda, while addressing a press briefing at the World Health Organization virtually.

Using VIA, a low-cost, point-of-care method, trained health workers will screen women for cervical cancer. Those who test positive will then be referred to higher centers for diagnostic confirmation and further evaluation.

Viagra, a popular erectile dysfunction medication, may be the world's only existing treatment against Alzheimer's disease, according to over 20 experts.

A panel of 21 experts recently combed through anonymous nominations, clinical evidence and found that out of 80 existing medications that show potential in treating the neurodegenerative disorder.

Out of those, Sildenafil (Viagra) ranked first, with Zostavax (a shingles vaccine) and Riluzole (a drug used to treat amyotrophic lateral sclerosis) coming in second and third.

"Each of the priority candidates has evidence supporting relevant underlying mechanisms of action, non-clinical studies, and clinical evidence from epidemiological studies and/or preliminary clinical trials," the researchers wrote in their paper.

"The tolerability of each of these compounds is also suitable for administration to a frailer population of older individuals as part of a well-monitored clinical trial program. We therefore recommend each of these therapeutic approaches as a high priority for clinical trials for the treatment or prevention of Alzheimer's disease."

The researchers found that Viagra may support brain health in several ways. Studies suggest it can promote the growth of nerve extensions (neurites) and reduce abnormal tau protein activity as well as improve blood flow and oxygen supply to the brain.

Previous research also shows that the compound can reduce levels of amyloid-beta (Aβ42) in the hippocampus and lower markers of brain inflammation. Additionally, it can also protect neurons from amyloid-beta damage.

Scientists are yet to determine the exact mechanism behind how Viagra can help protect the brain from Alzheimer's-related damage.

What Is Alzheimer’s Disease?

Alzheimer's disease is one of the most common forms of dementia and mostly affects adults over the age of 65.

About 8.8 million Indians aged 60 and above are estimated to be living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.

Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.

Amyloid protein molecules stick together in brain cells, forming clumps called plaques. At the same time, tau proteins twist together in fiber-like strands called tangles. The plaques and tangles block the brain's neurons from sending electrical and chemical signals back and forth.

Over time, this disruption causes permanent damage in the brain that leads to Alzheimer's disease and dementia, causing patients to lose their ability to speak, care for themselves or even respond to the world around them.

While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.

There is no cure for this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.

Can You Detect Alzheimer's Early On?

The US Food and Drug Administration has approved the use of a blood test which can help diagnose Alzheimer’s disease in adults aged 55 and above.

The blood test, known as Lumipulse, can detect amyloid plaques associated with Alzheimer’s disease and has proven to be a “less invasive option” that “reduces reliance on PET scans and increases diagnosis accessibility.”

FDA Commissioner Martin A. Makary said of the landmark decision, "Alzheimer’s disease impacts too many people, more than breast cancer and prostate cancer combined.

"Knowing that 10 percent of people aged 65 and older have Alzheimer's, and that by 2050 that number is expected to double, I am hopeful that new medical products such as this one will help patients."

It remains unclear when this test will be available for commercial use across the world.

Flo Health, a popular women's health app, has developed new digital tools which could shorten the time for endometriosis diagnosis by more than four years and reduce costs by thousands of dollars per patient across the US.

As of now, endometriosis affects an estimated 190 million of reproductive-age women worldwide, according to the World Health Organization. There is no cure for the chronic condition and access to early diagnosis and effective treatment can take years. Currently, the average time for a diagnosis is between four to 12 years.

However, a new npj Digital Medicine study suggests that Flo Health's Symptom Checker, specifically for endometriosis, alongside standard care could reduce the average time to diagnosis from 7 years to approximately 3 years with about 70 percent accuracy.

The research also found that using the checker allowed women to save $5,196 USD over a 40 year timespan, resulting from reduced medical costs and less productivity loss.

Anna Klepchukova, Chief Medical Officer at Flo Health, emphasized that the goal of such technology is to bridge the gap between symptom onset and clinical intervention.

“Endometriosis can deeply disrupt women’s lives, yet many spend years searching for answers within a system that hasn’t always been designed to connect the patterns they experience over time.

"This research explores how digital tools may help women better recognize their symptoms and bring clearer insights into conversations with their health care providers. While these tools aren't diagnostic, they support earlier awareness and more informed decisions, ultimately changing the trajectory of their care and their lives," she said.

What Is Endometriosis?

Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus, causing pain and other symptoms. According to Dr Anuradha Kapur, Principal Director (Obstetrics & Gynecology) & Head of Unit at Max Smart Super Speciality Hospital, Saket, symptoms can vary widely: “Many experience painful periods, pain during intercourse, bloating, and fatigue.

Others may have irregular bleeding, pain during bowel movements, and even asymptomatic cases,” she notes. Endometriosis is complex and can be difficult to diagnose, especially in asymptomatic cases or when symptoms overlap with other conditions like PCOS.

How Endometriosis Affects Life

Endometriosis can disrupt daily routines, impacting work and relationships due to fatigue and persistent pain. Dr Sonam Simpatwar, a reproductive medicine specialist at Central Railway Hospital, Byculla, Mumbai, highlights the importance of staying alert to symptoms, especially for those with risk factors like family history or high estrogen levels.

“Symptoms can be subtle, and many women may not experience severe signs until they face issues like infertility,” she noted.

For some, managing endometriosis involves lifestyle changes, pain management, and treatments ranging from hormonal therapies to surgical options. Regular gynaecological check-ups are crucial for catching signs early and avoiding long-term complications.

The PCOS and Endometriosis Connection

PCOS, or Polycystic Ovary Syndrome, is often confused with endometriosis due to some overlapping symptoms like irregular menstrual periods.

However, as Dr. Kapur explains, “PCOS doesn’t cause endometriosis. They are distinct conditions with different causes—PCOS results from hormonal imbalances, while endometriosis involves abnormal tissue growth outside the uterus.”

Although they don’t directly cause one another, patients with both conditions face unique challenges, including a higher risk of infertility, irregular cycles, and persistent pain.

Managing PCOS can be equally challenging, particularly because it’s closely tied to insulin resistance and weight. Lifestyle changes, such as a balanced diet and regular exercise, are often recommended, but these suggestions can sometimes become oversimplified, leaving patients feeling body-shamed or unsupported.
