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.

Irritable Bowel Syndrome (IBS) is a common but often overlooked gastrointestinal disorder; as a result, IBS is very prevalent, with less than 15% being diagnosed.
Individuals frequently experience recurrent symptoms such as bloated abdomen, abdominal pain, gas, diarrhea, or constipation, and normalize these symptoms over time or attribute them to "something they ate" or everyday stresses. Therefore, IBS remains undiagnosed for many years.
Why Diagnosis Is Often Delayed
One reason for this delay in being diagnosed is that the symptoms occur intermittently. It is also important to note that the presentation of these symptoms is inconsistent and unpredictable; there may be episodes where the IBS can last many days, and then completely resolve, thus providing a false sense of relief. Therefore, many individuals choose to delay consulting with a physician due to their belief that the symptoms they are experiencing are not serious.
Stigma Around Digestive Health
Another contributing factor is that there is still a degree of reluctance or discomfort associated with discussing problems related to the gastrointestinal tract openly; this only further complicates under-reporting statistics.
A ‘Functional’ Disorder Adds to Confusion
Finally, IBS is a functional disorder. Therefore, routine diagnostic testing will not reveal any visible abnormalities. Many patients may assume that the symptoms they are experiencing are not "real" or are not significant enough to warrant seeking medical attention, even though the discomfort they experience can be quite significant and affect their daily lives.
If you continually ignore symptoms of IBS, it will hurt your quality of life, productivity, and mental health. If you have persistent discomfort, you are likely to develop anxious feelings about eating, socializing, and travelling. Furthermore, if you don't manage your symptoms, you may experience a combination of untreated IBS with one or more other illnesses that are either gastrointestinal or metabolic; consequently, establishing the correct diagnosis for your IBS will be increasingly difficult as time goes on.
It is of the utmost importance to identify and respond to early warning signs of IBS as quickly as possible. A thorough evaluation can rule out other illnesses and provide a pathway for appropriate management, including dietary modifications, stress management techniques, and, if necessary, medical treatment.
Once you address your IBS, you will experience better control of your symptoms and eliminate the long-term consequences of IBS, both physically and psychologically.
Colorectal Cancer is not only one of the most common and deadly cancers, but is also one of the most preventable ones.
Unlike many other cancers, patients have a clear window of opportunity to stop it before it even begins. Almost always, these cancers start as small growths called polyps or precancerous lesions on the inner lining of the colon or rectum.
There is a long interval of time before polyps develop into cancer. During this time, they can be removed if they are identified. If a doctor removes a precancerous polyp during a routine screening, they would not only have nipped the cancer in the bud, but would have also prevented it from occurring.
However, there is a persistent taboo surrounding discussing bowel movements and other risk factors, and public understanding of its symptoms and crucial screening procedures frequently lags.
Dr Jeremy Clark, a consultant general surgeon specializing in colorectal diseases at Nuffield Health in Brighton, has underscored five critical warning signs the public must recognize, The Independent reported.
1. Blood in stool
“Passing blood when you go to the toilet is a worrying feature that you should flag to your GP,” Clark said, adding that the color can vary from bright red to almost black.
“If you see blood in the stools, particularly darker-colored blood or blood that’s actually mixed in with the stools, just once, and it’s significant, that should be reported to your doctor straight away. Don’t wait for that to keep on happening,” he added.
2. Changes in Bowel Habits
Dr. Clark stated that although more constipation may not be a risk factor, any sudden changes in bowel movements that last for a couple of weeks and do not go back to normal must be checked.
“If your bowels go from working once a day like clockwork, and then suddenly you’re going two or three times a day, and the bowels are a bit looser, that’s something that needs to be looked into,” the expert added.
3. Abdominal pain
Dr Clark highlighted that bowel cancers can cause abdominal pain, even in the initial days.
4. Bloatedness
The feeling of being 'quite often’ bloated may also indicate that something is going wrong in the bowel, Dr. Clark said.
5. Unexplained weight loss
Bowel cancers can impact digestion and cause weight loss

Dr Clark said that as these symptoms are common with other conditions, such as hemorrhoids or irritable bowel syndrome (IBS), people often ignore or easily dismiss these symptoms. He urged patients not to ignore and visit their doctor if they notice any of these symptoms.

What Is Colorectal Cancer?
The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.
It is a disease of the large bowel and a type of cancer that originates from the rectum or colon. A person's colon, cecum, rectum, and anus make up the large intestine.
According to experts, if you are above 45 years of age or have high-risk factors, you need to take the initiative to be screened.
The FIT (Fecal Immunochemical Test) is a simple, non-invasive at-home stool test kit that can collect a small sample of your feces, which can then be tested.
“If it comes back as positive, that means there is blood in your stools which needs to be investigated,” Clark said, adding that the next step is typically the Colonoscopy – the gold standard.
In most cases, a few careful habits are enough to prevent eye health from getting worse. (Photo credit: AI generated)
Summer can be difficult for the eyes, often in ways people do not immediately notice. Most of the attention during this season goes to drinking enough water, avoiding heat, and protecting the skin. Eye care usually comes much later, often only after discomfort begins. Long hours in the sun, dry surroundings, heat, and outdoor exposure can all leave the eyes feeling uneasy, especially over repeated days.
“During the summer season, we commonly see an increase in patients presenting with ocular surface discomfort, including dryness, itching, redness, burning sensation, and watering. Prolonged exposure to heat, ultraviolet radiation, dust, and air-conditioned environments can disturb the normal tear film and aggravate underlying allergic or dry eye conditions. In some cases, repeated eye rubbing and poor hygiene may also increase the risk of secondary irritation or infection. Timely preventive care and early attention to persistent symptoms are important to avoid worsening of these seasonal eye concerns,” says Dr Niteen Dedhia, Medical Director, Ojas Maxivision Super Specialty Eye Hospitals.
A common experience during summer is that the eyes simply do not feel as comfortable as they usually do. There may be a slight burning sensation, or the eyes may feel tired much earlier in the day, especially after being outdoors or spending hours in cooled indoor spaces. With the body losing fluids more quickly in hot weather, the eyes can also feel the effects. Many people do not immediately connect this discomfort to dehydration, but it plays a bigger role than expected. Added screen time indoors only makes this more noticeable.
During summer, the eyes are exposed to many small everyday irritants. Dust on the roads, dry wind, pollution, and even sweat can all add to the discomfort. In some people, this shows up as itching, mild redness, or watering that keeps returning. Rubbing the eyes may feel like the easiest response, but it often makes the irritation worse. If this continues for days, even a minor problem can start feeling quite troublesome.
Spending time in strong sunlight can be more exhausting for the eyes than most people realise. It is not just the brightness — by the end of the day, the eyes may feel heavy, watery, or unusually sensitive to light. Many people wear sunglasses, but not every pair is suitable for eye protection. Dark lenses may reduce glare, but that does not always mean they are blocking harmful rays. This is one reason discomfort can continue even when someone feels they have protected their eyes properly.
Managing summer eye discomfort does not require anything complicated. Staying well hydrated throughout the day helps more than most people expect. Using good-quality sunglasses, limiting time in the harsh afternoon sun, and simply rinsing the eyes after coming back from outside can ease a lot of irritation. Clean habits also matter in day-to-day care. Using your own towel, avoiding frequent hand contact with the eyes, and stepping away from screens occasionally can all help reduce strain and irritation.
