People receiving weight-loss drug Wegovy sustained weight loss for up to four years, shedding an average of 10% of their body weight in that time, as per a new study. Wegrovy is a brand that markets semaglutide injections, that have gained widespread attention for their weight-loss effects. The study also found that Semaglutide injections boost an individual's heart health, even when weight loss doesn't take place.

The study, called SELECT, was published in journal Nature Medicine. "At four years, we see ongoing benefits of semaglutide," said Cheng-Han Chen, MD, interventional cardiologist from Cardiologist, who was not involved in the research. Besides the weight loss, it also lead to a loss in cardiovascular outcomes.

The research was conducted on 17000 adults, who had obesity but did not have diabetes. Overall, people who received once-weekly injections of semaglutide lost on average 10.2% of their body weight over the course of four years. All of the study participants continued to lose weight for about 65 weeks, a year and three months, and then their weight remained at a stable level.

Were There Any Side Effects?

However, people's experience with the medication varied. Researchers found no unexpected safety issues with drug during trial. In fact, most the people who withdrew from the study were those who experienced the known symptsoms of the semaglutide injections like nausea, indigestion etc. This occurred mainly during the beginning of the study, as the dose of the medicine is increased to a maximally tolerated dose.

What Did The Results Say?

Of the people on the highest dose of Wegovy, 68% lost at least 5% of their body weight. This compared to 21% of people on the placebo. Additionally, of the total people on Wegovy about 23% lost at least 15% of their body weight. For those in the placebo group, only 1.7% lost that much body weight.

Semaglutide Shows Heart Benefits Beyond Weight Loss

Researchers found that even individuals who did not experience significant weight reduction while on the drug saw a reduced risk of major heart events. Recent analysis of the SELECT trial data revealed that semaglutide significantly lowers the risk of heart attack, stroke, and cardiovascular-related deaths in adults with obesity or those who are overweight. Notably, the results of this study lead the US FDA to approve Novo Nordisk's Wegovy for reducing heart-related risks in this group.

What Is Semaglutide?

Semglutide is the synthetic version of GLP-1—a natural hormone produced in the intestines that regulates blood sugar, appetite, and digestion. Now, every time you eat, your body produces various hormones, including GLP-1. These are called Post nutrition hormones, and help you absorb the energy you just consumed. GLP-1 travels to your pancreas, prompting it to produce insulin. It also travels to the hypothalamus in your brain, which gives you the feeling of being full or satiated. Ozempic imitates this hormone, thereby, silencing the food chatter in the brain. Interestingly, for some people this food chatter is really quiet ( people with low appetite) and for others it is an outburst, (people who generally binge eat.) So with Ozempic, silencing this self-talk in the brain, people tend to lose their appetite and eventually weight.

Are Their Any Side Effects Of Semaglutide?

Semaglutide, marketed under the brand name Wegovy, is primarily an antidiabetic medication used to treat Type 2 diabetes. It is also an anti-obesity drug used for long-term weight management. While it can be taken as a subcutaneous injection or orally, it has significant side effects. It primarily impacts your gastrointestinal tract and its side effects include constipation, nausea, abdominal pain, diarrhoea, and fatigue amongst others.

World Organ Donation Day 2026: Too Old Or Too Sick To Donate Organs? Doctors Bust Key Myths

Updated Aug 13, 2026 | 10:36 AM IST

SummaryA record 173,727 solid-organ transplants were performed worldwide in 2024, but demand continues to exceed supply. India performed 20,019 organ transplants in 2025, nearly four times the number in 2013.

Organ donation is one of the most generous gifts a person can give. Age, diabetes, hypertension or other medical conditions do not automatically rule out organ donation, doctors said on World Organ Donation Day.

Observed on August 13 every year, World Organ Donation Day aims to raise awareness about the need for organ and tissue donation and honour donors and their families.

Organ Donation After Brain Death

Dr. Umesh Gupta, Director and HOD, Nephrology and Kidney Transplant, Aakash Healthcare Multi-Speciality Hospital, Dwarka, told HealthandMe that organ donation can be considered when brain function is permanently lost and cannot be restored.

Brain death occurs when all functions of the brain and brainstem have permanently stopped.

“Brain death is different from a coma or a prolonged unconscious state. In brain death, the person cannot regain consciousness or breathe independently. Mechanical support may continue to keep the heart beating and preserve the condition of organs for a limited period, which is why organ donation can be considered,” he said.

Depending on the donor’s medical condition, organs such as the heart, liver, kidneys, lungs and pancreas may be suitable for transplantation.

Who Can Donate Organs?

Age alone does not rule out organ donation. Eligibility is assessed individually by the transplant team.

Doctors evaluate:

  • Health and functioning of individual organs
  • Existing illnesses
  • Infections
  • Medical history
  • Other factors that could affect transplant safety
"The most important message is: do not decide for yourself that you are “too old” or “too unwell” to donate. Leave that decision to the transplant team," Dr. Saurabh Anand, Chief - Neuroanaesthesia and Neurocritical Care, Artemis Hospitals, told HealthandMe.

Can People With Diabetes or Hypertension Donate?

People with well-controlled diabetes or hypertension may still be eligible to donate certain organs or tissues, said Dr. Shailesh Chandra Sahay, Senior Director - Urology, Kidney Transplant, Robotic Surgery, Max Super Speciality Hospital, Patparganj.

Modern transplantation practices allow doctors to assess each organ individually rather than excluding a donor solely because of age or a particular diagnosis.

Every potential donor deserves a medical evaluation. An organ that may appear unsuitable to a person could ultimately give another patient a second chance at life.

Blood Group Is Important — But Not the Only Factor

Blood group compatibility is an important consideration in organ transplantation.

“A blood group O donor typically donates to O recipients, while AB recipients can receive organs from all ABO blood groups in many transplant settings,” Dr. Saurabh said.

However, compatibility involves more than blood type. Doctors also assess:

  • Tissue compatibility
  • Antibodies
  • Organ size
  • Recipient’s overall health

World Organ Donation Day 2026: Why Donation Matters

  • One deceased donor can potentially save up to eight lives through vital organ donation.
  • Tissue donation can improve the lives of many more people.
  • A record 173,727 solid-organ transplants were performed worldwide in 2024, but demand continues to exceed supply.
  • India performed 20,019 organ transplants in 2025, nearly four times the number in 2013.
  • As of March 3, 2026, 89,839 patients were on India’s national waiting list for major organs.
  • Only around 18% of transplants currently involve deceased-donor organs.
  • More than 4.8 lakh Indians have pledged to donate organs and tissues after death since September 2023.

Why Non-Smokers Too Are At High Risk Of Lung Cancer

Updated Aug 13, 2026 | 07:11 AM IST

SummaryLong-term exposure to second-hand smoke, air pollution, radon gas, asbestos, diesel exhaust, and certain workplace chemicals has been linked to an increased risk.

Lung cancer has long been associated with smoking, but this is no longer the complete picture. While tobacco remains the leading cause, an increasing number of people who have never smoked are also being diagnosed with the disease. This changing pattern highlights the need to look beyond smoking alone when considering lung cancer risk.

In non-smokers, lung cancer is often diagnosed later because neither patients nor families may initially suspect the disease. As a result, symptoms are sometimes mistaken for common respiratory illnesses, delaying evaluation and treatment.

Why Non-Smokers Are Also at Risk

While smoking continues to account for most lung cancer cases, several other factors can also contribute. Long-term exposure to second-hand smoke, air pollution, radon gas, asbestos, diesel exhaust, and certain workplace chemicals has been linked to an increased risk. A family history of lung cancer or specific genetic mutations may also make some individuals more susceptible, even if they have never used tobacco.

In urban areas, prolonged exposure to polluted air is becoming an important concern. Fine particulate matter can enter deep into the lungs, causing long-term inflammation and damage that may increase the risk of developing lung disease, including cancer.

Symptoms That Should Not Be Ignored

Early lung cancer may not cause noticeable symptoms. When symptoms do appear, they should not be ignored, particularly if they persist for more than a few weeks. Symptoms that should be evaluated by a doctor include:

• A persistent cough that does not improve

• Coughing up blood

• Chest pain

• Shortness of breath

• Unexplained weight loss

• Repeated chest infections

• Hoarseness of voice

• Persistent fatigue

These symptoms can occur due to several conditions and do not always indicate lung cancer. However, persistent or worsening symptoms should be assessed promptly to identify the underlying cause and begin appropriate treatment if needed.

Why Early Diagnosis Makes a Difference

Finding lung cancer at an early stage improves the chances of successful treatment. Individuals with prolonged exposure to environmental or occupational risk factors, or those with a strong family history of lung cancer, should discuss their risk with a doctor. Imaging tests such as chest CT scans and, when indicated, molecular testing help identify the type of lung cancer and support treatment planning.

Looking Beyond Smoking

Not every case of lung cancer can be prevented, but reducing exposure to tobacco smoke, avoiding harmful occupational exposures, improving indoor air quality where possible, and seeking medical advice for persistent respiratory symptoms can help protect lung health. Greater awareness that lung cancer can affect both smokers and non-smokers may lead to earlier diagnosis, timely treatment, and better outcomes.

H1N1 Flu Rising in India: Why Heart Patients Need to Watch

Updated Aug 12, 2026 | 09:43 PM IST

SummaryAlthough H1N1 influenza primarily affects the respiratory tract, the infection can also put additional strain on the heart in some people, particularly those with a chronic history of cardiovascular disease.
H1N1 Flu Rising in India: Why Heart Patients Need to Watch

Influenza strain H1N1, formerly known as swine flu, is rising significantly in India, with deaths also being reported in some states.

H1N1 is a subtype of Influenza A and can cause sudden fever, cough, sore throat, headache, body aches and fatigue. These symptoms can overlap with those of other seasonal influenza strains, COVID-19 and respiratory syncytial virus (RSV), making it difficult to identify the infection based on symptoms alone.

H1N1 Cases and Deaths Reported in States

Delhi: According to official data, Delhi has reported 1,349 confirmed H1N1 infections. No official deaths have been reported.

Kerala: A total of 2,468 influenza cases were recorded in the state in July, with 24 deaths reported during the month. The total number of cases recorded in the state this year stands at 5,519, with 60 deaths reported.

Maharashtra: The state has reported 25 laboratory-confirmed H1N1 cases, including a major spike of 15 cases in July. One confirmed death was officially verified by the Nagpur Municipal Corporation (NMC) Death Audit Committee.

Gujarat: H1N1 activity is also being reported, with Ahmedabad currently seeing a rise in cases.

Although H1N1 influenza primarily affects the respiratory tract, the infection can also put additional strain on the heart in some people, particularly those with a chronic history of cardiovascular disease, experts told HealthandMe.

How H1N1 Can Strain the Heart

Fever, dehydration, increased levels of carbon dioxide in the body, decreased oxygen levels and the body’s inflammatory response can increase the workload on the heart during an H1N1 infection.

This added strain may be more concerning for people who already have cardiovascular disease, said Dr. Praveen Raman Mishra, Associate Consultant, Institute of Cardiac Sciences at ShardaCare – Healthcity.

Heart Problems Linked to H1N1

Some H1N1 influenza patients may experience cardiovascular complications, including:

  • Inflammation of the heart
  • Abnormal heartbeats
  • Worsening of heart failure
These problems may occur as the body responds to the infection and the heart faces increased demands.

Dr. Saurabh Gupta, Associate Director, Internal Medicine, Yashoda Medicity, added that H1N1 infection may cause fluctuations in heart rhythm or inflammation associated with the heart.

“In some circumstances when suffering from the H1N1 virus, although the initial symptoms of the virus may be those shared with the normal flu, such as temperature, aches and cough, those with pre-existing heart conditions should be more vigilant whilst they’re recuperating,” he told HealthandMe.

“As the infection puts more work on the body, you can find that previous heart problems are more noticeable,” he added.

Warning Signs to Watch For After H1N1

The experts noted that people recovering from H1N1 should seek medical attention if they develop symptoms such as:

  • Severe chest pain
  • Shortness of breath
  • A high or fluttering pulse
  • Sudden faintness
  • Severe weakness
According to Dr. Mishra, these symptoms could indicate a problem involving the cardiovascular system. Early evaluation is important because such complications can be treatable when detected promptly.

Who Should Be Particularly Careful?

People with a chronic history of cardiovascular disease may face greater strain on the heart during H1N1 infection.

Monitoring symptoms during recovery and seeking medical attention when concerning symptoms develop can help identify cardiovascular problems early.
