Wegovy® is an injectable prescription medicine to treat adults with metabolic dysfunction-associated steatohepatitis (MASH) with moderate to advanced liver scarring (fibrosis), but not with cirrhosis of the liver, along with a reduced calorie diet and increased physical activity. This indication is approved based on improvement of MASH and liver scarring (fibrosis). There is an ongoing study to confirm the clinical benefit of Wegovy® in adults with MASH.
What causes MASH?
MASH is short for metabolic dysfunction–associated steatohepatitis. When metabolism is altered, it can lead to the development of MASH. To learn more, explore common phrases related to MASH in the Glossary.
MASH and metabolic dysfunction
MASH is caused by metabolic dysfunction. That means your metabolism, or how the body processes food into energy, isn’t working properly. Normally, your liver helps process nutrients, including fats and sugars, from the food you eat. When metabolism is altered, your liver begins storing too much fat. This can lead to MASH, which can further progress leading to liver scarring (fibrosis).
What increases your risk for MASH?
MASH isn’t just a liver issue. Certain health conditions are associated with an increased risk for MASH, and these may be signs of metabolic dysfunction.
If you are living with any of the health conditions below, talk to your health care professional (HCP) about your personal risk for developing MASH with liver scarring.
Fatty liver or family history of cirrhosis
Type 2 diabetes or prediabetes
Obesity
High blood pressure
High triglycerides
(a type of fat)
Low HDL
(good cholesterol)
Persistently elevated liver enzymes (over 6 months)
PCOS (polycystic ovary syndrome)
HDL, high-density lipoprotein.
Actor portrayals.
Find a health care professional.
Screening helps detect MASH early. There are several ways to screen and test for MASH and liver scarring, including noninvasive options. If you think you're at risk for MASH or are already diagnosed, ask your HCP what the right next step is for you.
