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.

When one hears about plastic surgery, he or she usually associates it with beauty operations designed to improve one's appearance.

Reconstructive plastic surgery is a very particular field of medicine that addresses problems with the restoration of patients' form and functions who suffer from trauma, cancer, birth defects, burns, and complicated wounds. For many people, reconstructive surgery is far from beautification. It is all about getting back to an independent life.

Reconstructive Surgery After Trauma and Cancer

Injuries that can occur following accidents on the road, incidents at industries, electric burns, and animal bites often lead to severe destruction to the skin, muscles, tendons, nerves, blood vessels, and bones. In addition, cancers of the breast, head and neck, mouth, skin, and limb regions are often treated with extensive surgical excisions to provide complete clearance from the disease.

Though these operations are necessary to save lives, they might lead to considerable impairment and deformities in the patients. Reconstructive plastic surgery helps solve these problems.

Advanced Techniques in Modern Reconstruction

Today's reconstruction surgery uses sophisticated methods, including microsurgical free tissue transfer, perforator flaps, local and regional flap reconstruction, split-thickness and full-thickness skin grafting, nerve grafting, tendon reconstruction, and vascular anastomosis.

The application of microsurgery, in particular, has greatly improved the possibilities for performing reconstruction surgeries through transferring viable tissue from one region of the body to another with the re-establishment of blood supply from blood vessels of just one to three millimeters in diameter using a surgical microscope.

Restoring Function After Cancer Surgery

One of the biggest breakthroughs in the field of reconstructive surgery has been in the area of post-cancer treatment. Women who have undergone surgery due to breast cancer have the option to undergo either immediate or delayed breast reconstruction surgery through implants or through autologous tissues to help restore their self-image and mental well-being.

Similarly, patients who have undergone surgery due to oral, jaw, or facial cancer can improve their functionality and social standing through microvascular surgery.

Burn Reconstruction and Functional Recovery

The other significant factor to consider is the importance of reconstructive surgery in the treatment of burns. Severe burns typically lead to contracture scars and limited movement of joints.

Excision, skin grafting, flaps, and scar revision surgeries are key in improving function, aesthetics, and reducing disability. Reconstruction of hands following injuries or burns allows people to carry out their daily tasks and work.

Restoring Hope Beyond Surgery

Reconstruction is not limited to the surgical theater but is best done using a multi-disciplinary team comprising plastic surgeons, oncologists, trauma surgeons, physiotherapists, occupational therapists, psychologists, dietitians, and rehabilitators. Rehabilitation, scar management, physiotherapy, and follow-up are just as important after surgery as the surgery itself.

Reconstructive plastic surgery is thus much more than a field of surgery; it is a specialty whose goal is to restore hope. Through a blend of surgical skills and compassion, it gives people an opportunity to transcend the physical and psychological effects of injuries or cancers. For many people, it changes the experience of survival into that of recovery.

With the onset of the monsoon, the risk of several water-borne, mosquito-borne, and bacterial infections increases significantly due to stagnant water, flooding, poor sanitation, and contaminated food and water.

Many of these diseases can start with mild symptoms similar to the flu, but if they're diagnosed early, you can get the appropriate medical care in time, avoiding serious complications.

Early Symptoms Of Various Monsoon Diseases

One of the important ways to prevent monsoon infections and diseases is to identify warning signs early, Dr. Amit Saraf, Director, Department of Internal Medicine, Jupiter Hospital, told HealthandMe.

Leptospirosis

Leptospirosis gained attention after its cases surged in Kerala recently. The infection has also been reported in Maharashtra, Gujarat, Tamil Nadu, and Karnataka. The bacterial infection typically spreads via contact with water or soil that has been contaminated by the urine of animals infected with leptospirosis, especially during floods.

Initial signs and symptoms include:

• High fever

• Chills

• Intense muscle pain (especially in calves)

• Headache

• Red eyes

• Nausea

• Vomiting

“Wearing protective footwear, avoiding wading in floodwaters, and covering any open wounds will help minimize the risk of infection,” Dr Saraf recommended.

Typhoid

• High fever

• Headache

• Weakness

• Loss of appetite,

• Abdominal pain

• Constipation or diarrhea

• Body aches

Dr. Saraf said: “It can cause serious gastrointestinal issues if not treated. Safe drinking water, good hand hygiene, and freshly cooked food are important preventive measures.”

Cholera

Cholera is a water-borne bacterial disease that commonly occurs during monsoons. It often begins with excessive watery stools, vomiting, leg cramps, and rapid dehydration. Dehydration can quickly become an immediate danger of cholera.

The doctor said: “Prevention includes drinking clean water, eating hygienically prepared food, and practicing proper sanitation and handwashing.”

Dengue

Dengue is one of the most common viral diseases spread by Aedes mosquitoes. Often reported in various Indian states during the monsoon, dengue presents with flu-like symptoms. Dengue usually begins with high fever, severe headache, pain behind the eyes, extreme muscle and joint pain, nausea, skin rash, and fatigue.

Malaria

Malaria, a common monsoon disease, is spread by infected mosquitoes and characterized by the following symptoms:

• Recurrent fever

• Shivering or sweats

• Headache

• Muscle pain

• Weakness

• Nausea

• Vomiting

Dr Saraf said, “Early diagnosis is important to prevent severe diseases. The best ways of preventing mosquito bites are by using mosquito repellents, mosquito nets, and the elimination of breeding sites.”

Chikungunya

Mosquito-borne viral diseases are reported to be the highest during the rainy season. One of them is Chikungunya. The infection is usually marked by sudden high fever and severe joint pain in the limbs. Other early symptoms may include headache, muscle pain, fatigue, and skin rash.

“The infection is usually not deadly but can cause joint pain for weeks or months. Preventive measures include mosquito control and avoidance of mosquito bites,” the expert advises.

Gastrointestinal Infections

During the monsoon period, gastrointestinal infections are also more common as food and water sources are more likely to get contaminated. Early signs of gut infections may include diarrhea, vomiting, cramps, nausea, bloating, fever, and dehydration.

The majority are due to bacteria, viruses, or parasites. The expert said that the risks can be minimized by maintaining food hygiene, drinking boiled or purified water, washing fruit and vegetables before cooking and consuming, and refraining from eating street foods and drinks.

Many people associate allergies with outdoor pollution, dust, or seasonal changes. However, doctors are increasingly seeing another factor contributing to allergic reactions: the indoor environment.

Allergies Worsening Even When You Stay Indoors?

Over the last two years, there has been a definite increase in patients coming in with respiratory issues. Many people who develop asthma-like symptoms later in life often ask, “Doctor, we hardly go out. How can we develop these problems?” The answer often lies in the indoor pollutants and allergens that go unnoticed in everyday life.

Most people spend nearly 90% of their time indoors — at home, in offices, malls, cars, and other climate-controlled spaces. While staying indoors may feel safer than being exposed to outdoor pollution, it can sometimes mean longer exposure to allergens trapped inside. These may trigger a runny nose, itchy eyes, cough, sinus congestion, asthma, rashes, or hives.

Many indoor irritants are invisible. Common sources include dust mites, pet dander, fungi, chemical vapours from cleaning products, air fresheners, mosquito repellents, and cooking smoke. Poor ventilation or inadequate air exchange allows these allergens to remain trapped for long periods. In many urban homes, indoor air quality can sometimes be worse than outdoor air.

Primary Indoor Irritants That Trigger Allergies

Smoke is one of the most overlooked indoor triggers. Incense sticks, dhoop, and agarbattis, which are part of daily routines in many homes, generate smoke and fine particulate matter that can irritate the airways. Cooking smoke can also be harmful, especially when food is fried, roasted, or cooked with heavy spices. Mosquito coils are another common source. In short, any form of indoor smoke can affect respiratory health, particularly in people who already have allergies or asthma.

Dust is another major concern. Many households practise dry dusting every day, but this can push dust particles back into the air and worsen symptoms in those with dust allergy or asthma. Wet mopping, wet wiping, or vacuum cleaning are safer alternatives.

Air conditioning is another factor. AC filters that are not cleaned regularly can become clogged with dust, pollen, and fungal spores, which keep circulating indoors. Closed rooms with little fresh air make this worse. If anyone in the family smokes or uses vaping products, these are well-established indoor pollutants that can significantly impact respiratory health.

Modern interiors can add to the problem. Fabric sofas, heavy curtains, carpets, and excess furniture increase the surface area where dust collects, and dust mites thrive. Plug-in mosquito repellents, strong floor cleaners, aerosol sprays, room fresheners, smoking, and vaping indoors are also important for indoor pollutants.

How To Tackle It?

Lifestyle changes after the pandemic have worsened exposure. Work-from-home routines, online classes, longer screen time, and reduced outdoor activity mean people spend more hours in closed spaces with limited fresh air.

Small steps help - open windows when outdoor air quality allows, let sunlight in, wash bed linen and curtains regularly, clean AC filters, avoid dry dusting, check damp areas for mold, reduce incense smoke, mosquito coils, and strong fragrances, and air out stored clothes before use.

Pollution remains a concern, but it is no longer the only culprit. The way we live indoors today is quietly shaping our respiratory and immune health. Recognizing these hidden triggers early can prevent allergies from becoming a long-term lifestyle problem.
