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.

Heart Diseases Drop In US, But Still Is The Leading Cause Of Death

Updated Jan 24, 2026 | 09:46 AM IST

SummaryAn American Heart Association report shows U.S. heart disease deaths fell 2.7% from 2022 to 2023, the first decline in five years. Still, heart disease remains the leading killer, surpassing cancer and accidents combined. Experts stress prevention through healthy habits to cut deaths, costs, and long term risk nationwide significantly overall.

Fewer people are dying of heart disease, however, as per a new report from the American Heart Association (AHA), it is still the leading cause of death in the US. While the report noted a drop in rates of deaths by heart diseases for the first time in five years, the report also noted that it kills more American than any other condition. The report was published early Wednesday in the journal Circulation.

What Did The AHA Report Reveal?

The report found that annual rates of heart disease deaths have in fact decreased by 2.7% between 2022 and 2023. This means it went from 941,652 to 915, 973. However, cardiovascular diseases still killed more people in the US than cancer and accidents combined.

The report found that deaths caused by blockages in the coronary arteries, the blood vessels supplying the heart, fell by 5.9%, dropping from 371,506 to 349,470 over the same period. Coronary artery disease, a major cause of heart attacks, still claims two lives every three minutes. Other vessel-damaging chronic conditions also remain widespread.

The report found that the share of U.S. adults with high blood pressure edged up to 47.3%, while overall obesity rates dipped slightly to 50%. However, obesity is increasing among children and teenagers, rising from 25.4% to 28.1% in those aged 2 to 19.

Prevention remains the most powerful tool to reduce heart disease deaths, experts say. Because heart disease cannot be cured, waiting for symptoms often means focusing only on treatment rather than stopping the problem early. Early prevention, by contrast, has a much bigger impact on saving lives.

The report highlights four key lifestyle habits for heart health: eating a balanced diet, staying physically active, getting enough sleep and avoiding tobacco. It also stresses four important health measures: managing weight, cholesterol, blood sugar and blood pressure.

Together, these eight factors could prevent up to 40% of heart disease deaths and cut the risk of developing serious heart disease symptoms by as much as 74%. These same habits also benefit the brain, helping slow brain ageing and lower the risk of dementia, especially by keeping blood pressure under control.

Heart Health Is Also an Economic Issue

Cutting down cardiovascular disease in the U.S. would not only help people live healthier lives, it could also ease the strain on the economy, experts say. Heart disease carries a massive financial cost, with an estimated $414.7 billion spent each year on direct treatment and indirect losses between 2021 and 2022.

Even though the benefits of healthy habits are well known, getting people to prioritize heart health remains difficult. Only one in four U.S. adults meets national guidelines for both aerobic and muscle-strengthening exercise. Control of chronic conditions is also lacking, with less than half of Americans with type 2 diabetes managing their disease effectively.

Experts stress that regular physical activity, tailored to individual ability, can make a real difference. Simple, consistent movement and timely health checkups can go a long way in protecting both personal health and the wider economy.

Boys Need HPV Vaccination to Prevent Cancer, Experts Warn

Updated Jan 24, 2026 | 12:00 PM IST

SummaryExperts are warning that the Human Papillomavirus (HPV), a sexually transmitted virus, can cause a variety of cancers in men, some of which are on the rise, such as penile, head and neck. Studies have also shown a high incidence of HPV-associated cancers among men. About 25,000 HPV-associated cancer cases among men were reported in 2025.

Human Papillomavirus (HPV), a sexually transmitted virus, is most commonly known to cause cervical cancer and cancers affecting the vagina, vulva, anus and throat in women.

However, experts are now warning that it can also cause a variety of cancers in men, too, some of which are on the rise and young teenage boys should also receive the HPV vaccination for adequate protection.

The European Cancer Organisation noted in a LinkedIn post: "HPV affects everyone, regardless of gender. It can lead to cancers of the cervix, mouth and throat, anus and penis. This is why universal protection is so important.

"Yet, vaccination rates for boys remain much lower than for girls in many countries, creating an avoidable gap in protection that places countless young people at risk for cancers later in life."

According to Dr David Pfister, an oncologist at Memorial Sloan Kettering Cancer Centre, New York, the HPV vaccine protects men from penile, neck and head cancer. He also noted that while a pap test detects early-stage cervical cancer in women, no such test exists for penile, anal, or head and neck cancers in men, which can worsen their survival rate.

Dr Pfister explained: "Developing something like a pap test for throat cancer would be a game-changer. When you compare the throat to the cervix, the anatomy of sites like the tonsils and the base of the tongue have hard-to-reach crevices the virus can hide in.

"Until an effective and reliable screening test is developed, patients should stay up to date on their HPV vaccines, know how the disease is acquired, and take any suspicious symptoms like a lump in the neck or blood in the phlegm to their doctor or dentist."

How Does HPV Spread And Is It Life-Threatening?

HPV is primarily spread through skin-to-skin contact during sexual activity. While many HPV infections clear on their own, high-risk types of HPV can become life-threatening if they persist and lead to cancers, especially when detected late.

Regular screenings such as pap tests and vaccinations against high-risk types are crucial for prevention.

When Should You Get The HPV Vaccination?

The HPV vaccine is approved and recommended for:

  • Girls aged nine to 45 years
  • Boys aged nine to 26 years
For children aged nine to 14, two doses of the vaccine are generally sufficient, administered several months apart. However, individuals aged 15 and above require three doses for full protection. Even if the vaccine is missed at age 9, catch-up vaccinations are available up to age 26, and in some cases beyond, depending on medical advice.

The age limit for getting vaccinated is based on the assumption that most people have had sex and may have potentially been exposed to multiple strains of HPV by adulthood. If you’ve already been exposed to the virus, the vaccine will not be of benefit.

The HPV vaccine does not require a booster shot, according to the Cleaveland Clinic.

Are HPV-Caused Cancers On The Rise In India?

Yes, according to Apollo Diagnostics, about 365.71 million women over age 15 live in India and are at risk of developing cervical cancer. Moreover, over 130,000 Indian women are diagnosed with cervical cancer cases annually and nearly 75,000 die of the disease.

Recently, doctors have also observed a rise in HPV-linked neck and head cancers in young Indians, in their 20s and 30s. Studies have also shown a high incidence of HPV-associated cancers among men. About 25,000 HPV-associated cancer cases among men were reported in 2025.

Another study conducted in two Indian cities among 300 HIV-positive men who have sex with men found an anal HPV prevalence of 95 percent.

Could You Be Overdoing Iron Supplements? Four Signs Doctors Say Not To Ignore

Updated Jan 24, 2026 | 02:00 AM IST

Summary Taking too much iron can be harmful. NHS warns of four key symptoms that may signal excess intake, how much iron adults need, and safe supplement advice.

Britons who regularly take a commonly used supplement are being urged to cut back if they notice four particular symptoms, as excessive intake can be dangerous and, in some cases, life-threatening. Vitamins and minerals are essential for keeping the body functioning properly. While most nutrients should ideally come from a healthy, balanced diet, many people choose to top up their intake with supplements.

Iron is one such supplement. This mineral plays a key role in making haemoglobin, the substance in red blood cells that carries oxygen around the body. When iron levels are too low, it can lead to iron deficiency anaemia. This condition may cause symptoms such as constant tiredness, low energy, shortness of breath, and heart palpitations. To avoid this, some people turn to iron supplements.

Could You Be Overdoing Iron Supplements?

The NHS has issued guidance on its website, warning that taking “too much” iron can cause side effects. These include:

  • Constipation
  • Feeling sick
  • Being sick
  • Stomach pain

If these symptoms appear, it may be a sign that your iron intake needs to be reduced. In children, taking too much iron can be particularly dangerous and may even be fatal.

The NHS states: “Very high doses of iron can be fatal, particularly if taken by children, so always keep iron supplements out of the reach of children.” For adults, a high dose of iron is classed as more than 20mg.

How Much Iron Do You Need?

  • 8.7mg a day for men aged 19 and over
  • 14.8mg a day for women aged 19 to 49
  • 8.7mg a day for women aged 50 and over
  • Women who continue to have periods after the age of 50 may need the same amount of iron as women aged 19 to 49

The Department of Health and Social Care (DHSC) says that “most people” should be able to meet their iron needs through a varied and balanced diet. But for those who do take supplements, the NHS advises: “Do not take too much as this could be harmful.”

It adds that taking 17mg or less of iron supplements each day is “unlikely” to cause harm. The guidance continues: “But continue taking a higher dose if advised to by a GP.”

Good sources of iron include:

  • Liver (but this should be avoided during pregnancy)
  • Red meat (though the DHSC advises limiting red and processed meat due to a possible link to bowel cancer)
  • Beans, such as red kidney beans, edamame beans, and chickpeas
  • Nuts
  • Dried fruit, including dried apricots
  • Fortified breakfast cereals
  • Soybean flour

Symptoms Of Iron Deficiency Anaemia

  • Tiredness and low energy
  • Shortness of breath
  • Noticeable heartbeats, also known as heart palpitations
  • Skin that appears paler than usual
  • Headaches
  • Ringing, buzzing, or hissing sounds in the ears or head, known as tinnitus
  • Food tasting unusual
  • Itchy skin
  • A sore tongue
  • Hair loss, with more hair coming out during brushing or washing
  • Craving non-food items such as paper or ice, a condition called pica
  • Difficulty swallowing, known as dysphagia
  • Painful open sores at the corners of the mouth
  • Changes to the nails, including spoon-shaped nails
  • Restless legs syndrome
