Wegovy may also be used for other conditions as determined by your health care provider.
How does Wegovy work (mechanism of action)?
Wegovy works for weight loss by reducing appetite and slowing down the movement of food through your body. Weight loss from Wegovy can lead to improved cardiovascular risk factors, such as decreased blood pressure, improved cholesterol levels, and better control of blood sugar. In people with MASH, fat builds up in the liver causing inflammation. Weight loss helps reduce fat in the liver, potentially reducing inflammation and scarring.

Upcoming Surgery or Procedure. Tell your health care provider that you use Wegovy before any planned surgeries or procedures that require anesthesia or deep sedation. Wegovy causes your stomach to empty more slowly which can increase the risk of food getting into your lungs (aspiration) during surgery or procedures.
