Weight loss is usually considered a good thing, unexpected and extreme weight loss can be a sign of something in your body going very wrong. There could be some underlying issues that are causing your body to pull weight and nutrition from your muscles and body fat to keep you going. As you grow old, your limbs grow weaker, and same for your muscles, so you do lose some weight as you age, but losing a lot of it too quickly could be a sign of something much worse, Dementia. A recent study published in JAMA Network Open 2025 Cardiometabolic Trajectories Preceding Dementia in Community-Dwelling Older Individuals, has identified potential early indicators of dementia, including significant weight loss and specific digestive changes, appearing years before noticeable cognitive decline.

The study showed that people who later got dementia had their Body Mass Index, or BMI, go down faster than those who stayed healthy. BMI is a way to see if someone's weight is healthy for their height. This drop in BMI started happening many years before they were told they had dementia, sometimes as early as 11 years ago. Also, these people often started with a lower BMI to begin with. So, even though everyone's weight might change a little as they get older, the people who developed dementia had a much bigger and faster weight loss.

What Are Some Other Indicators Of Dementia?

Along with their BMI, the size of their waist also changed. People who ended up with dementia had smaller waist sizes, and this difference was noticeable about 10 years before they were diagnosed. This means that their bodies were changing in ways that showed up long before they or their doctors noticed any problems. So, not only was there weight loss, but also a loss of abdominal fat. This measurement is important because fat around the waist can be related to other health issues.

The study also found changes in their blood. Specifically, the "good" cholesterol, called HDL, went up in people who developed dementia. This increase happened about five years before they were diagnosed. It's tricky because HDL is usually seen as a good thing for your heart. But in this case, it seems like it might be a sign of changes happening in the brain. Scientists are still trying to understand why this happens.

Weight Loss Doesn’t Cause Dementia, Dementia Causes Weight Loss

When we see that people with dementia lose weight, it's easy to think that the weight loss is what caused dementia. But experts think it's the other way around. They call this "reverse causation." This means that the brain changes that cause dementia also cause people to lose weight. The brain changes can affect things like appetite, how the body uses food, and how people go about their daily lives. For example, people might forget to eat, have trouble making meals, or move around less.

While the study revealed a lot about different indicators of dementia and bodily changes, there are many limitations to the study. Everyone loses some weight as they get older. So, it's hard to know when weight loss is just a normal part of aging and when it's a sign of dementia. The study found that people with dementia lost weight faster, but it's still tricky to tell the difference in everyday life. Doctors need to look at other things, like memory tests, to figure out if someone's weight loss is a cause for concern.

If someone is losing weight without trying, and they're also having problems with their memory or thinking, it's important to talk to a doctor. It's not just about the weight loss; it's about the whole picture.

Every year, National Doctors' Day is observed on July 1 to commemorate the birth and death anniversaries of Dr. Bidhan Chandra Roy, a renowned physician, freedom fighter, and educationist.

The National Doctors' Day 2026 theme is "Behind the Mask: Who Heals the Healers?" This year's theme highlights the importance of supporting the mental, emotional and physical well-being of doctors who dedicate their lives to caring for others.

On the occasion of Doctors' Day, HealthandMe spoke to medical experts who highlighted the growing concern over violence against healthcare workers. They warned that such incidents not only endanger doctors but also weaken the entire healthcare system.

The experts stressed that violence affects patient care, lowers morale among healthcare professionals and erodes trust between doctors and patients.

Their concerns are supported by recent research highlighting the scale of workplace violence faced by doctors in India.

A 2026 study published in the National Medical Journal of India, researchers from the Institute of Human Behaviour and Allied Sciences (IHBAS), and Dr. Ram Manohar Lohia Hospital, and Atal Bihari Vajpayee Institute of Medical Sciences (ABVIMS) found that 80.2 per cent of doctors in India reported having faced or witnessed workplace violence.

Verbal abuse was identified as the most common form, followed by physical and sexual violence. The incidents affected doctors' mental health, with the impact lasting from several weeks to as long as a year.

The study also found that two-fifths of doctors sustained physical injuries, including 7.8 per cent who suffered grievous injuries.

More worryingly, only about one-third of doctors reported such incidents to hospital authorities or professional medical bodies. Even when complaints were made, no action was taken in nearly half the cases, suggesting gaps in institutional accountability.

Why Violence Against Doctors Happens

According to Dr Ishwar Gilada, Secretary General People's Health Organisation, India, several factors contribute to violence against doctors.

These include "high patient expectations, poor clinical outcomes, inadequate communication between doctors and patients, an overburdened healthcare system, high out-of-pocket medical expenses, weak security, misinformation, 'Mr. Google' providing false information, and limited accountability for perpetrators".

Dr. Tejinder Singh, Senior Consultant, Medical Oncology, Apollo Cancer Centres, Apollo Hospitals, Navi Mumbai added that anger and frustration arising from a patient's condition can sometimes fuel violent behavior, but emphasized that respect and meaningful dialogue are essential.

Impact On Patients And The Healthcare System

The experts said violence against healthcare workers has consequences that extend far beyond individual doctors.

Dr. Rajeev Jayadevan, former President of the Indian Medical Association (IMA) Cochin and Convener of the Research Cell, Kerala told HealthandMe that healthcare workers—including doctors, nurses, technicians and other staff—cannot give their best to patients if they are working under the threat of violence.

Dr. Gilada told HealthandMe that violence affects emergency care, lowers doctors' morale, increases attrition among healthcare professionals and encourages defensive medicine, where doctors order more tests to safeguard their own interests. He also warned that such incidents contribute to an erosion of trust between doctors, patients and the healthcare system.

Dr. Tejinder described violence against doctors as violence against the healthcare system itself, saying it creates a harmful atmosphere that ultimately affects patient care.

Not Every Poor Outcome Is Medical Negligence

Dr. Rajeev said there is often a perception that a poor outcome for a patient is the fault of the doctor or the hospital. He stressed that many adverse outcomes are part of the complex disease process within the body and can occur despite the best possible treatment.

Dr. Tejinder told HealthandMe that doctors are also human and that medical science cannot guarantee that every patient's problem can be cured, even when doctors do their best.

What Is The Solution?

The experts proposed multiple measures to reduce violence against healthcare workers.

Dr. Gilada called for stronger legal protection, saying the Healthcare Protection and Clinical Services Act (Prevention of Violence Act) 2025 should be passed into law. He also recommended improving doctor-patient communication, strengthening hospital systems and increasing public awareness through collaboration among healthcare agencies, patients, communities, government bodies and law enforcement agencies.

Dr. Rajeev said hospitals should establish effective grievance redressal systems so that patients' concerns can be addressed before they escalate into violence. He also said healthcare establishments should be declared peaceful zones where violence is prohibited.

Dr. Tejinder urged patients and families to maintain open dialogue with doctors, emphasizing that doctors and patients ultimately share the same goal—the well-being and betterment of the patient.

Preventive healthcare through early screening, healthier lifestyles and greater public awareness is crucial to reducing the burden of both communicable and chronic diseases, doctors said ahead of National Doctors' Day.

National Doctors' Day is observed in India on July 1 to honor the contributions of medical professionals.

Shift Focus On Prevention

Speaking at an event organized by the Illness to Wellness Foundation, Rajesh Bhushan, former Secretary, Ministry of Health and Family Welfare, said India has made significant strides in expanding access to healthcare and strengthening its treatment infrastructure.

"The next phase of our healthcare journey must focus equally on prevention," Bhushan said.

He stressed that preventive healthcare should become a national priority, supported by regular screening, early diagnosis, healthier lifestyles and greater public awareness.

"Preventive healthcare is not only a public health priority but also an economic imperative for building a healthier and more productive nation," he added.

India Faces A Double 9-0

Prof. (Dr.) Nirmal Kumar Ganguly, former Director General of the Indian Council of Medical Research (ICMR), said India is battling both infectious diseases and a rapidly growing burden of lifestyle-related illnesses.

"One of the biggest health challenges India faces today is the growing burden of obesity, which is the root cause of many major non-communicable diseases. Preventive healthcare is the most effective way to address both communicable and non-communicable diseases."

India continues to report a high burden of communicable diseases such as tuberculosis, malaria, dengue, cholera, typhoid, HIV/AIDS, hepatitis B and hepatitis C, which together account for about 27.5% of the country's disease burden.

At the same time, non-communicable diseases—including obesity, diabetes, hypertension and cancer—are rising rapidly. Around 60% of all deaths in India are caused by NCDs, with nearly 70% of their risk factors linked to unhealthy lifestyles.

Prevention Can Improve Quality Of Life

Prof. (Dr.) G. C. Khilnani, Chairman, PSRI Institute of Pulmonary, Critical Care & Sleep Medicine, said preventive healthcare should become part of everyday life through regular health check-ups, balanced nutrition, physical activity, vaccination, good hygiene and timely medical consultation.

Dr. Yash Gulati, Padma Shri awardee and Senior Consultant Orthopaedic and Joint Replacement Surgeon at Apollo Hospitals, New Delhi encouraged people to treat preventive healthcare as a lifelong commitment rather than an occasional health check-up.

"Every step taken towards prevention today reduces the burden of disease tomorrow."

How To Prevent Diseases

Doctors said adopting a prevention-first approach can significantly reduce the risk of both communicable and chronic diseases. They recommended:

• Going for regular health screenings to detect diseases early.
• Exercising regularly, including walking, yoga or other physical activities.
• Eating a balanced diet rich in fruits, vegetables, whole grains and fiber.
• Maintaining a healthy weight to reduce the risk of obesity, diabetes and heart disease.
• Getting adequate sleep and manage stress through meditation or relaxation techniques.
• Staying up to date with vaccinations to prevent infectious diseases.
• Maintaining good hygiene, including frequent handwashing and access to safe drinking water.
• Seeking timely medical advice instead of waiting for symptoms to worsen.

Aarogya Setu started as a contact-tracing and tracking app during the COVID-19 pandemic. But it underwent a significant transformation since its initial launch. Now, years after its launch, the Centre has launched Aarogya Setu 2.0.

Aarogya Setu 2.0 Aims To Solve Everyday Healthcare Problems

Instead of focusing only on infectious diseases, Aarogya Setu 2.0 now acts as a comprehensive healthcare app that provides a range of healthcare services. Its features are designed to change the way you obtain medical services in hospitals and other healthcare facilities.

It can help users store, retrieve, and manage their medical records, access various services, and simplify everyday healthcare tasks. Apart from data and records storage, the app can help users locate the nearest hospitals, manage their prescriptions, and track their insurance coverage seamlessly. The revamped platform is designed to address common challenges patients face while navigating India's healthcare system.

Here's a closer look:

Finding Closest Hospitals

One of the most useful features Aarogya Setu 2.0 provides is access to the locations of the closest hospitals and healthcare facilities. In times of emergencies, this feature could prove to be lifesaving as it could save valuable time when immediate medical attention is needed.

The app has also enabled searching for PM-JAY empanelled hospitals. This feature is integrated with Pradhan Mantri Jan Arogya Yojana, allowing users to search for empanelled hospitals offering cashless treatment. Users can easily find authorized hospitals and access free or subsidized care.

Retrieving Medical History During Doctor Visits

Patients often struggle to recall their medical history, including details like previous illnesses, surgeries, allergies, medications, or vaccinations during a consultation. It often hinders the diagnostic process as the doctor does not have a comprehensive picture of the patient’s health.

The platform provides users with easy access to their health records, making it simpler to share relevant information with their healthcare providers whenever needed.

Avoiding Repetitive Diagnostic Tests

Patients are often compelled to undergo the same diagnostic tests and scans simply because their previous reports get misplaced. This not only increases healthcare costs but also causes inconvenience. Easy access to past laboratory reports can help patients avoid unnecessary repeat tests.

Simplifying Insurance And Cashless Treatment

Medical insurance paperwork often involves submitting hospital documents, prescriptions, diagnostic reports, and discharge summaries. Since many of these records are scattered across different hospitals or stored as paper documents, patients may spend considerable time collecting them.

With digital health records stored in one place, users may find it easier to retrieve documents required for insurance claims or cashless hospitalization, potentially reducing paperwork and delays.

Making Healthcare More Portable

Aarogya Setu 2.0 allows users to securely store and access digital health records through integration with India's digital health ecosystem. Having previous prescriptions and reports readily available can help both patients and healthcare providers make informed decisions.

This is particularly useful for individuals who relocate frequently and suffer from chronic conditions such as diabetes, hypertension, asthma, thyroid disorders, or kidney disease that need long-term monitoring.

Changing cities usually means changing doctors and hospitals. In the absence of a complete medical history, one is more likely to incur additional healthcare costs of retaking the tests.
