Drugs for weight loss - how do they work and are they effective?

If a healthy diet, regular physical activity and supplementation with weight loss aids are not enough, after consulting a doctor, you can start weight loss treatment with the use of prescription products. These are drugs in the form of oral tablets or capsules (e.g. bupropion, naltrexone, orlistat) and injections (e.g. liraglutide, semaglutide, tirzepatide).
