How Colesevelam (Welchol) works
Colesevelam (Welchol) is a bile acid sequestrant. It works by attaching to bile acid in your intestines to prevent it from being absorbed into your body. This causes your liver to turn the cholesterol in your body into bile acid to replace what couldn't get absorbed. As a result, the amount of cholesterol in your body drops.
Colesevelam (Welchol) can also help lower blood sugar in adults with Type 2 diabetes. It's not exactly known how it works. But it's thought to work by raising the levels of a protein called glucagon-like peptide 1 (GLP-1) that releases insulin.
