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.

The word dialysis can stir up anxiety and fear for many. It's often seen as a sign of life never being the same again or it's considered a "last resort. I see many patients every day who assume that dialysis is their only choice. In fact, dialysis is a life saving therapy which takes over some of the functions of the kidneys which are unable to perform them properly. Knowing about the dialysis that it will require in the future, how dialysis works, and whether it can be delayed or avoided will help you avoid unnecessary anxiety and make informed decisions.
The kidneys are incredible organs that constantly filter out excessive fluid, toxins and waste products from the blood and help to keep the body's electrolyte balance, blood pressure and red blood cell production in check. As kidney function decreases substantially, these functions are disturbed and allow the build-up of harmful substances in the body. Dialysis mimics some of these filtering functions, and works to keep a patient healthy when their kidneys no longer do so.
Dialysis is not started just because of a laboratory value as is often thought. Many people think that dialysis is meant as a next step when kidney function drops below a certain percentage. But it depends on the results of kidney function tests, symptoms, and fluid overload, as well as electrolyte problems and patient clinical condition. Some people with an advanced stage of CKD may be able to do just fine and have no indication of needing dialysis for months; others might need urgent dialysis in case their kidneys are failing very quickly or they develop very serious complications that put their life at risk.
The most frequent indications for initiation of dialysis are: very high potassium levels, symptoms of fluid overload such as breathlessness, nausea and vomiting caused by accumulation of toxins, confusion, extreme tiredness, loss of appetite or condition where the dialysis cannot be managed with medication alone. In these cases, dialysis is not a choice but a lifesaver.

There are two types of dialysis: In hemodialysis, the blood is pumped through a dialysis machine that removes waste products and excess fluid from the blood and returns the cleaned blood to the body. It's typically done three times a week in a dialysis center, but a few patients have home dialysis as an option. The process is usually a four hour per session process.
Another option is peritoneal dialysis, which involves using the patient's own abdominal lining to filter the blood. The abdominal cavity is filled with a cleansing solution, waste products and excess fluid are carried in to the solution through a permanent catheter, and the solution is drained. This treatment is often available at home and can provide a patient with more flexibility and independence. Medical suitability, lifestyle, home support and patient preference will all influence the decision on whether to undergo hemodialysis or PD.

A major concern patients have is if they can avoid dialysis altogether. The answer is dependent on the cause of kidney disease and the timeliness of diagnosis. However, in many cases, the kidney disease is a progressive condition over many years and there is a chance to slow the progression of the disease with appropriate medical treatment and lifestyle changes. Well managed diabetes and hypertension, avoiding unnecessary pain killers like non-steroidal anti-inflammatory drugs (NSAIDs), healthy weight, salt reduction in the diet, smoking cessation and frequent visits to a nephrologist can have a huge impact on slowing the deterioration of the kidneys.
An early diagnosis is very important. Sadly, a major drawback about chronic kidney disease is that most of the time, people don't have any symptoms in the initial stages of the disease. People are often diagnosed when they have significant kidney damage already. Routine screening is particularly important for those with diabetes, hypertension, cardiovascular disease, obesity and a family history of kidney disease. A number of simple blood and urine tests can detect kidney disease before symptoms occur.
It is also crucial to differentiate acute kidney injury from chronic kidney disease. Acute kidney injury can occur if the kidneys become severely dehydrated, if the body be

“It’s only because I use my phone so much” We all know the excuse. It’s true that texting too much or using your hand in a certain way when holding your phone can be irritating and temporary. But not all your symptoms are the screen’s fault! Symptoms like tingling, burning or pins-and-needles may be due to a pinched or irritated nerve.
A familiar example of such a condition is carpal tunnel syndrome, wherein pressure gets on the median nerve at the wrist, causing finger and hand numbness and tingling of your thumb, index and middle finger as well as part of ring finger, which are usually felt mostly at nighttime, or when you’re using the phone for too long.
An alternative would be compression of the ulnar nerve leading to symptom production with the little and part of the ring finger. Remaining with a bent elbow for prolonged durations can lead to increased symptoms, for example if using a telephone.

The pain doesn't always come from the hand. We could have some irritation of the nerve from a little higher up, right to from the neck. Problems with the cervical spine can be referred around the neck, and down the arm and into the hand as pain, and tingling or numbness or weakness.
That’s why just cutting back on screen time won’t help if an nerve issue is also going on. A second common error is to let your numbness progress so much that the cause becomes obvious before looking for medical care. Initial symptoms often come and go after the amount of time your nerves are compressed and can be worse if your nerves are compressed while you sleep or play an activity. Eventually, if nerve compression worsen, your symptoms may occur more often and may be paired with a weakness of the hand, or problems with the more precise dexterity manoeuvres.
Warning signs People also need to be aware of early signs of damage like dropping objects; problems with buttoning a shirt; having weakened grip strength or feeling like your hand feels weak when you hold something tight; or an ongoing general weakness. Those should never be ignored. There can be a link with phones because you hold your hand in the one position when holding and looking at it for a while your wrist, your elbow, your neck. But the problem isn't necessarily the phone itself.
Whether it is a repetitive motion or it comes on from something that has already occurred such as finding out you have diabetes or even have an already injured and pinched nerve in your wrist or at your elbow or even at your shoulder. Some simple stretches, an altered grip, keeping your elbow bent at just about 90 degrees and trying not to bend your wrist way backward will all work to your benefit.
If numbness continues or weakness is increasing, pain is intense, or the sensations spread from the neck into the arm, you may need to see a physician for further examination, including possible nerve conduction studies, imaging, or blood tests based on their findings.
Not all sensations or tingling in your hand are "phone related", although it might seem obvious. A perceived annoyance can occasionally be the start of significant nerve compression requiring evaluation.

When people hear about oral cancer, they often think first of smoking or chewing tobacco. However, several other risks deserve attention, especially because people who have never used tobacco can still develop the disease.
One of the least understood risk factors is alcohol consumption. Although alcohol is commonly linked to liver disease, its impact on oral cancer risk is also important.
Alcohol can damage the tissue lining of the mouth through the production of acetaldehyde, a chemical compound that interferes with the cells' ability to repair themselves. It can also dry and irritate the lining of the mouth, making it more vulnerable to other carcinogens. This risk increases with consistent, regular alcohol use. In combination with tobacco, alcohol can further increase the absorption of carcinogens into oral tissues.

Areca nut is another important risk factor and is considered carcinogenic. It may be consumed as supari, gutkha or paan. Regular chewing can cause oral submucous fibrosis, a condition that causes progressive stiffness of the mouth and significantly increases the risk of oral cancer.
Human papillomavirus (HPV), particularly certain high-risk strains, is another recognised cause of throat and oropharyngeal cancers. Chronic irritation from sharp teeth, damaged dental crowns or ill-fitting dentures may also warrant attention.
Certain chronic inflammatory conditions of the mouth, such as oral lichen planus, can cause persistent lesions and require regular monitoring, particularly when symptoms or the appearance of the lesions change.
Sun exposure is another lesser-known risk, particularly for lip cancer. People who work outdoors without adequate protection can accumulate significant UV exposure over many years.
Most importantly, the mouth should be monitored whenever something unusual appears. A mouth ulcer that persists for more than two weeks, red or white patches, unexplained bleeding, difficulty swallowing, numbness, or a lump in the mouth or neck should be evaluated by a doctor.
Quitting smoking remains crucial for cancer prevention, but protecting against oral cancer requires looking beyond tobacco and recognising the less obvious risks as well.
