Clinical trials included adults up to their mid-70s, and weight loss benefits were seen across age groups. There’s limited evidence directly comparing older versus younger adults, but no major differences in effectiveness have been noted, though older people may be more sensitive to side effects. Who was included in the trials The large clinical trials of semaglutide, such as the STEP programme, included adults with overweight or obesity up to about 75 years old. This means w

Wegovy is made as a biologic medicine, meaning it uses recombinant technology to produce semaglutide, a protein-based drug. Mysimba and Orlistat, by contrast, are small-molecule tablets made by chemical synthesis. These differences influence regulation and supply but not day-to-day use for patients. What makes Wegovy a biologic Wegovy (semaglutide) belongs to a group of medicines known as biologics. These are typically large, complex molecules produced in living cells using r

Both contain semaglutide and improve blood sugar by enhancing insulin release and reducing glucagon. Ozempic is specifically licensed for diabetes at lower doses, while Wegovy provides the same benefits at higher doses alongside more pronounced weight reduction. How semaglutide works on blood sugar Semaglutide, the active ingredient in both Wegovy and Ozempic, belongs to the GLP-1 receptor agonist family. It lowers blood sugar by stimulating insulin release when glucose level

Yes — trials show Wegovy users lose more weight earlier than with Saxenda, thanks to its stronger appetite effect and weekly dosing. That said, both require steady use over months for results to build. The two medicines at a glance Wegovy and Saxenda belong to the same family of medicines, GLP-1 receptor agonists. They help people feel fuller sooner, reduce appetite, and support healthier eating. The difference lies in the active ingredient and how they are dosed: Wegovy cont

Wegovy mimics the hormone GLP-1, acting on the brain to reduce appetite and slow digestion. Contrave (naltrexone/bupropion) affects brain reward and craving pathways, which can reduce emotional eating but doesn’t directly target satiety hormones. How Wegovy works Wegovy (semaglutide 2.4 mg weekly) is a GLP-1 receptor agonist. It mimics a natural gut hormone called GLP-1, which signals to the brain that you are full, slows down stomach emptying, and enhances insulin release wh

Both Wegovy (semaglutide 2.4 mg) and Trulicity (dulaglutide) improve blood sugar, but semaglutide generally produces greater reductions in HbA1c and body weight. NICE recommends semaglutide more widely for people needing weight-focused management. Two GLP-1 medicines, one key difference Wegovy and Trulicity both belong to the GLP-1 receptor agonist family of medicines. They mimic the hormone GLP-1, which reduces appetite, slows digestion, and stimulates insulin release when b

The most common side effects with Wegovy are gastrointestinal, such as nausea and diarrhoea, and these often lessen over time. Other medicines have different risks: Orlistat can cause oily stools, Mysimba may raise blood pressure, and phentermine (not used in the UK) carries cardiovascular risks. Understanding risk in context All weight-loss medicines come with benefits and risks. Doctors weigh these carefully before prescribing, taking into account a person’s health conditio

Yes, Wegovy has strong evidence in people with type 2 diabetes, cardiovascular disease, and sleep apnoea, where weight loss can improve outcomes. Other drugs may be chosen if semaglutide is unsuitable, but few have shown the same range of benefits across multiple health conditions. Why certain conditions matter Weight-related health problems often go beyond the number on the scales. People with obesity are more likely to develop type 2 diabetes, cardiovascular disease, and sl

No, even though both contain semaglutide, they are licensed for different uses and come in different devices and doses. Doctors may...

The SELECT trial showed semaglutide 2.4 mg (Wegovy) reduced the risk of major heart problems in people with overweight or obesity and cardiovascular disease. Orlistat, while useful for modest weight loss, has not shown the same scale of cardiovascular benefits in large outcome studies. Two very different medicines Wegovy and Orlistat are both prescribed for weight management, but they work in completely different ways. Wegovy (semaglutide) is a GLP-1 receptor agonist that red

In the UK, coverage depends on NHS commissioning rather than insurance, and NICE now recommends Wegovy within specialist services. Saxenda has more limited NHS use. In private healthcare or in other countries, coverage varies by insurer, but newer guidance tends to prioritise Wegovy because of its stronger results. The UK context: NHS commissioning, not insurance Unlike in the United States, where health insurance policies determine which drugs are covered, the UK relies on t

Yes, NICE guidance states that Wegovy can be offered to adults with a BMI over 35 and at least one weight-related condition, or sometimes with a BMI over 30 if criteria are met. Other drugs, like Saxenda or Mysimba, have similar but slightly different BMI thresholds, while diabetes drugs like Trulicity are prescribed on blood sugar criteria instead. Wegovy and its eligibility rules In the UK, NICE sets out clear criteria for who can be prescribed Wegovy. It is recommended for

Trials such as STEP-1 and SELECT showed Wegovy not only reduced weight but also improved blood pressure, cholesterol, and markers of heart health. Other medicines, like Saxenda, also improve some metabolic measures but to a smaller extent, and drugs like Orlistat mainly affect fat absorption rather than broad cardiometabolic outcomes. Why metabolic health matters Weight management is not just about the number on the scales. Many of the health risks linked to excess weight — i

In STEP trials, people using Wegovy started to see weight changes within the first 4–8 weeks, with maximum effects building over about a year. Ozempic, studied mainly for diabetes, also showed early improvements in blood sugar and weight within weeks, but average weight loss was smaller because of its lower doses. Early signs of progress One of the most common questions people ask is how soon results can be seen. In clinical trials of Wegovy (semaglutide 2.4 mg), participants
