Weight loss injections are one of the most searched topics in skin, hair and aesthetics right now, and we get asked about them every week across our Delhi clinics. Brands like Mounjaro and Ozempic have made GLP-1 medicines a regular topic of conversation since they became available in India. If you are wondering how they actually work, how much weight people lose, what they cost, and whether they are right for you, here is a straightforward guide written in plain language. These are prescription medicines, so the most important point up front is simple: they should only ever be used under proper medical supervision after a personalised assessment.
Most of the injections people ask about belong to a group called GLP-1 medicines. Mounjaro contains tirzepatide and also acts on a second hormone called GIP, while Ozempic and Wegovy contain semaglutide. In simple terms, these medicines mimic hormones your gut naturally releases after eating. They help you feel full sooner, reduce appetite and food cravings, and slow how quickly the stomach empties. Many people describe a noticeable drop in what some call food noise, the constant background thinking about the next meal. They are taken as a small weekly injection and work best alongside sensible eating and regular activity, not instead of it.
This is the question we hear most, and an honest answer matters more than a flashy number. In clinical trials, people on tirzepatide at higher doses lost on average around 15 to 22 percent of their body weight over roughly 72 weeks, when combined with diet and lifestyle changes. Semaglutide trials have shown averages closer to 10 to 15 percent over a similar period. Those are averages from studies, not promises. Real results vary a lot from person to person depending on starting weight, dose, consistency, diet, activity and individual biology. Some people respond strongly, others more modestly. Anyone guaranteeing you a fixed number of kilos is overselling it.
Cost is a fair concern because this is usually an ongoing treatment rather than a one off. As a general guide for Mounjaro in India, vials have been priced around ₹3,500 for the 2.5 mg strength and about ₹4,375 for 5 mg, which works out to roughly ₹14,000 to ₹17,500 per month at starting doses. Higher doses and pen versions can cost more. Prices change over time and vary by pharmacy and dose, so treat these as ballpark figures to plan around rather than a fixed quote. During a consultation we can talk through the realistic monthly commitment for your situation so there are no surprises.
There is no single right answer for everyone. A head to head trial comparing tirzepatide and semaglutide suggested tirzepatide produced greater average weight loss, but the better choice for you depends on your health history, how you tolerate the medicine, availability, cost and your doctor's judgement. Some people tolerate one better than the other. This is exactly the kind of decision that should be made with a qualified doctor rather than from a social media post.
The most common side effects are digestive: nausea, vomiting, diarrhoea, constipation and reduced appetite, especially in the early weeks or after a dose increase. These often settle as the body adjusts, and starting low and increasing slowly is designed to reduce them. Less commonly, more serious issues can occur, which is why these medicines are prescription only and need a proper medical history first. They are not suitable for everyone. A careful assessment helps flag anything that makes them a poor fit for you.
This is an important and honest point. For many people, appetite returns when the medicine stops, and some weight can come back if eating and activity habits have not changed alongside it. That is why we see these injections as one tool within a wider, medically supervised plan that builds sustainable habits, rather than a quick fix you take forever without thought. The goal is lasting change, and the medicine is there to support it.
It can be tempting to buy these injections online or copy a friend's dose, but that carries real risks: wrong dosing, unsuitable candidates, fake products and unmanaged side effects. A supervised program means a proper health check first, the right starting dose, monitoring as you go, and support with nutrition and lifestyle so the results have a chance to last. Our team focuses on safe, realistic and personalised care rather than one size fits all promises.
Weight loss injections can be a genuinely useful tool for some people when used correctly and under medical guidance, but they are not magic and they are not for everyone. The best next step is an honest consultation where we assess your health, explain your options clearly, and recommend what genuinely suits you.
