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.
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.
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.
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.

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

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.
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.
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.
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.
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.

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.
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.
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.
Some H1N1 influenza patients may experience cardiovascular complications, including:
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.
The experts noted that people recovering from H1N1 should seek medical attention if they develop symptoms such as:
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.
