What are bile acid sequestrants drugs?
Bile acid sequestrants are medicines that help lower your LDL (bad) cholesterol. Too much cholesterol in your blood can stick to the walls of your arteries and narrow or block them. These medicines work by blocking bile acid in your stomach from being absorbed in your blood.
Where are bile acid sequestrants absorbed?
Bile acid sequestrants bind bile acids in the intestine and increase the excretion of bile acids in the stool. This reduces the amount of bile acids returning to the liver and forces the liver to produce more bile acids to replace the bile acids lost in the stool.
Why do bile acid sequestrants cause constipation?
Constipation can be an important side effect of cholestyramine, perhaps because the presence of free bile acids in the intestine helps determine the amount of water in stool, and cholestyramine binds the free bile acids.
Why do bile acid sequestrants increase triglycerides?
The bile acid sequestrants bind to these acids, reducing their supply. In turn, this stimulates the liver to produce more bile acids, which uses more cholesterol. Unfortunately, the resins can increase triglyceride levels. When the statins are not sufficient to lower high cholesterol, these drugs can be added.
What is the most common side effect of bile acid sequestrants?
Common side effects of bile acid sequestrants include: Constipation. Bloating. Heartburn.
What color is bile acid diarrhea?
Yellow/Pale Brown/Grey: Bright yellow diarrhea can signify a condition known as Giardiasis (see sidebar). Stool that is yellow or pale can also result from reduced production of bile salts, since a normal, brown-coloured stool acquires its hue from breaking down bile.

Why do bile acid resins increase triglycerides?
