Victoza activates GLP-1 receptors, which prompts the pancreas to release more insulin when blood sugar rises and reduces glucagon, a hormone that signals the liver to produce glucose. It also slows how quickly food leaves the stomach, lowering after-meal blood sugar spikes and reducing appetite.
These actions target the metabolic drivers behind MASLD and MASH: insulin resistance, chronically elevated blood sugar, and excess body weight. As insulin resistance improves and the liver produces less glucose, fat tends to build up less in liver cells, and the inflammation that drives disease progression may ease.
For patients with MASLD or MASH, these metabolic changes can support treatment goals such as better blood sugar control, gradual weight loss, and a lower risk of disease progression. Victoza is not used on its own — providers pair it with dietary changes, physical activity, and regular monitoring, such as Liver Function Tests (LFTs), to support these outcomes.
