Weight loss medications have been around for decades, but the latest generation of drugs has created a frenzy like never before. Initially developed to manage diabetes, medications such as Ozempic, Wegovy, Mounjaro, and Zepbound have been repurposed for weight loss, with some users reporting dramatic results. These GLP-1 receptor agonists work by mimicking gut hormones that help regulate appetite and insulin levels. As their popularity reaches stratospheric levels, questions are now being asked: Are the drugs a breakthrough, or is the situation more complex?
These medications work by making people feel fuller sooner and for a longer period of time. Research indicates that people on Wegovy (semaglutide) lose about 12% of their weight, while those on Zepbound (tirzepatide) lose about 18%. Besides losing weight, these drugs also appear to have other health benefits like lowering blood pressure, decreasing the risk of heart attacks and strokes, and even potentially treating neurological disorders like Alzheimer's and Parkinson's.
Although these medications have promising outcomes, they do carry potential risks. The most prevalent side effects are nausea, vomiting, fatigue, diarrhea, and constipation. Although most individuals adapt to the medication with time, some develop severe reactions. There have been lawsuits filed against pharmaceutical firms by patients who suffered serious gastrointestinal disorders like stomach paralysis and bowel blockages.
The other increasing concern is the psychological one. Patients are urged to stay on the drugs even in the face of adverse effects, which makes them have terrible experiences that degrade their quality of life. Consequently, a large percentage of users drop the medication within several months. A recent survey in the journal Obesity revealed that 19% of people put on these medications were still on them after a year.
GLP-1 medications have been approved by the FDA only for obese patients (BMI of 30 or higher) or those with weight-related conditions such as hypertension. Yet, high demand has resulted in off-label prescribing on a large scale, with people getting them even if they do not qualify. This demand has created national shortages, and the FDA has permitted compounding pharmacies to make generic versions.
Even though they work, access is not an option for most. Insurance only covers them minimally, and Medicare will only pay for weight loss medication if it is for diabetes. With the average cost being $1,300 per month, people from low-income communities, statistically with higher obesity rates, can't afford these drugs.
Although these drugs are beneficial for one's health, their use in cosmetic weight loss has also come into limelight. Social media is full of sensationalized "before and after" pictures, which create unrealistic hopes. But the so-called "Ozempic face" has been a harsh reminder that weight loss is not necessarily translated into a healthier and younger looks.
Do You Have to Take These Weight Loss Medications Forever?
One of the most contentious issues with GLP-1 medications is the long-term commitment they necessitate. Recent studies suggest that those who stop taking these medications tend to regain the weight lost. The human body, evolved over time, is programmed to store fat effectively—rendering long-term weight loss a life-long struggle for many.
While lifestyle changes like diet and exercise are crucial aspects of weight control, they're usually not enough by themselves for people with obesity. The question is: Are these drugs a short-term solution, or are they a lifetime solution? And more so, should patients be required to continue taking them for the rest of their lives to keep the weight off?
GLP-1 drugs have unquestionably revolutionized the weight loss scenario, giving hope to millions. Yet, they are far from a silver bullet. The cost, access concerns, side effects, and long-term dependence are all valid issues. Although they do possess undeniable advantages, their efficacy and sustainability are based on the patient's capacity to follow the regimen and accept possible risks.
Before they decide, people need to balance the pros against the cons and seek the advice of healthcare professionals to see whether these drugs fit into their health agenda. As science continues to develop, the future of GLP-1s is potentially even brighter—but for now, they are both a revolutionary solution and a highly contentious issue in the battle against obesity.
While pharmaceutical manufacturers continue to innovate and perfect weight loss drugs, future research will be what decides their long-term effect. US pharma major Eli Lilly launched the much-awaited diabetes and obesity management drug Mounjaro in India on Thursday at one-fifth of the US price. With obesity rates rising in India, the market for weight loss drugs has grown exponentially in the country. Novo Nordisk's oral semaglutide tablet, Rybelsus, launched in India in January 2022, has already captured nearly 65 per cent of the anti-obesity drugs market, which includes other weight-loss medications such as dulaglutide, orlistat, and liraglutide.

In a landmark decision, the U.S. Food and Drug Administration (FDA) has approved the use of the SAPIEN 3 transcatheter aortic valve replacement (TAVR) platform for patients with severe aortic stenosis who show no symptoms. This is the first-ever approval of TAVR therapy for asymptomatic patients, marking a significant shift in how this life-threatening condition may be treated going forward.
Aortic stenosis is a narrowing of the aortic valve opening, which restricts blood flow from the heart to the rest of the body. In severe cases, the heart must work harder to pump blood, which can eventually lead to heart failure. While some patients experience chest pain, breathlessness, or fainting, others show no outward symptoms despite the seriousness of the condition.
The danger lies in the unpredictability—many asymptomatic patients may suddenly deteriorate, experiencing life-threatening events without warning. Until now, clinical guidelines advised “watchful waiting” for these patients, meaning treatment was delayed until symptoms appeared.
Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure that replaces the narrowed aortic valve without the need for open-heart surgery. The SAPIEN 3 is a next-generation TAVR device developed by Edwards Lifesciences. It is inserted via a catheter, usually through the femoral artery in the leg, and guided to the heart, where it expands and takes over the function of the diseased valve.
SAPIEN 3 is already widely used in patients with symptomatic severe aortic stenosis. With this new FDA approval, its use extends to a new, broader population of asymptomatic patients.
The decision was largely based on findings from the EARLY TAVR trial, a randomized clinical study that enrolled over 900 patients with severe aortic stenosis who had no symptoms. Participants were divided into two groups: one received TAVR using the SAPIEN 3 valve, while the other was monitored with watchful waiting.
After a median follow-up of 3.8 years, the trial found that:
The FDA’s approval of the SAPIEN 3 platform for asymptomatic severe aortic stenosis patients could lead to changes in clinical guidelines, encouraging earlier evaluation and treatment.
“There is an urgent need to change practice and TAVR guidelines,” said Dr. Philippe Genereux of Morristown Medical Center, who was involved in the EARLY TAVR trial. He emphasized that patients who seem stable can become symptomatic without warning, and early TAVR offers an opportunity to improve outcomes and ease the burden on the health care system.

Poultry-related outbreak has been on going in the US, especially with the ever on going bird flu. Recently, yet another outbreak has been associated with backyard poultry which has sickened at least seven people in six states. This is the new salmonella outbreak. The health officials have confirmed its news this Monday.
As per the Centers for Disease Control and Prevention (CDC), two cases were identified in Missouri, and one each in Florida, Illinois, South Dakota, Utah and Wisconsin.
The CDC noted that most people started falling sick in February and March of this year. All of them had the same strain of salmonella, which is a version that has been traced to hatcheries in the past. The health officials confirmed that investigation with regards to this recent outbreak is on going.
As per the US Food and Drugs Administration (FDA), Salmonella are a group of bacteria that can cause gastrointestinal illness and fever called salmonellosis. It can be spread by food handlers who do not wash their hands and/or the surfaces and tools they use between food preparation steps. It can also happen when people consume uncooked and raw food. Salmonella can also spread from animal to people.
FDA notes that people who have direct contact with certain animals, including poultry and reptiles can spread the bacteria from the animal to food if hand washing hygiene is not practiced.
Pets too could spread the bacteria within the home environment if they eat food contaminated with Salmonella.
Salmonella bacteria leads to infections in around 1.35 people in the United States, every year. However, the source does not always remain poultry. As per the CDC website Salmonella outbreaks previously have been linked with cucumbers, pet bearded dragons or gecko, eggs, small turtles, poultry, charcuterie meat, cantaloupes, diced onions, cookie dough, and flour.
The biggest concern with backyard poultry is that even if the chickens look clean and healthy, they could still carry salmonella bacteria. A backyard poultry associated outbreak which ended last year caused 470 cases, which were spread across 48 states and including one death.
FDA notes that most people infected with Salmonella will begin to develop symptoms 12 to 72 hours of the infection, which lasts for about four to seven days. Most people recover without treatment.
As per the CDC, each year, around 450 people diet in the United States due to acute salmonellosis.
Children who are younger than five and the elderly, and people with weakened immune system could be more at risk to have severe salmonellosis infections.

United States is experiencing its deadliest flu season for children in 15 years, according to a federal report released Friday. The Centers for Disease Control and Prevention (CDC) has reported 216 pediatric deaths so far this flu season—surpassing last year's 207 fatalities and marking the highest number since the 2009-2010 H1N1 pandemic.
The season is not yet over, making this already grim milestone even more concerning. In fact, the final death toll for the 2023-2024 flu season won’t be confirmed until later this year. "This number that we have now is almost certainly an undercount,” said Dr. Sean O’Leary of the American Academy of Paediatrics. “When the season is declared over, and they compile all the data, it’s almost certain to go up.”
O’Leary, who is also a pediatric infectious diseases specialist at the University of Colorado, pointed to declining flu vaccination rates among children as a key factor in this season’s severity. Over the past five years, the flu vaccination rate for children in the U.S. has dropped from about 64 per cent to just 49 per cent.
While flu vaccines do not always prevent infection, they are highly effective at reducing hospitalisations and deaths. "Flu vaccinations may not prevent people from coming down with symptoms, but research shows they are highly effective at preventing hospitalisations and deaths," O’Leary said.
This flu season has proven severe not only for children but for the general population as well. CDC estimates indicate at least 47 million illnesses, 610,000 hospitalisations, and 26,000 deaths so far. Among 5,200 adults hospitalised with the flu, 95 per cent had at least one pre-existing condition. In contrast, among 2,000 hospitalised children with more detailed health data, only about 53 per cent had underlying health issues such as asthma or obesity.
The CDC report did not include information on how many of the children who died had received the flu vaccine. Additionally, the agency did not provide a spokesperson to discuss the current season’s trends.
There is, however, a positive sign: flu activity has been declining since February. Last week, all 50 states reported low or minimal flu activity. The season also saw an unusual mix of circulating strains, with both H1N1 and H3N2 Type A viruses contributing significantly to infections. Earlier CDC data suggested that the flu vaccines offered this season were relatively effective in preventing hospitalisations and deaths.
The CDC continues to advise that everyone aged 6 months and older receive an annual flu vaccine.
The broader decline in childhood vaccinations is being fueled by online misinformation and the politicisation of vaccines, especially since the COVID-19 pandemic. Robert F. Kennedy Jr., who recently assumed the role of U.S. health secretary, has echoed antivaccine rhetoric, further influencing public opinion.
According to O’Leary, other factors may also be impacting flu vaccination rates. Pediatric clinics are often short-staffed and no longer holding as many after-hours vaccination events. Additionally, while more Americans are getting vaccinated at pharmacies, some drugstores do not offer flu shots for children.
"My hope is that this season will be a bit of a wake-up call for folks—that we actually do need to vaccinate our kids against influenza," O’Leary said.
