Common side effects of weight management medicines

Weight loss injections such as Mounjaro and Wegovy can be very helpful for suitable patients, but like all medicines, they can cause side effects.

Most side effects are linked to the digestive system. This is because these medicines affect appetite, fullness, stomach emptying and how the body responds to food. For many patients, side effects are mild and improve as the body adjusts. For others, symptoms can be more uncomfortable and may need extra support, a slower dose increase or a clinical review.

At Aster, we believe patients should know what to expect before starting treatment. Side effects are not something to panic about, but they should not be ignored either. The aim is to manage symptoms early, stay hydrated, eat enough and know when to ask for help.
