Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. According to the Mayo Clinic [2], statins such as Lipitor can cause digestive problems, including diarrhea, constipation, and nausea. However, the medication does not affect the digestion of all fats.

Lipitor works by blocking an enzyme in the liver that is responsible for producing cholesterol [2]. This reduces the amount of cholesterol in the bloodstream, which can lower the risk of heart disease. The medication does not affect the digestion of fats in the small intestine.

A study published in Circulation Research [3] found that atorvastatin treatment did not affect the absorption of dietary fat in rats. The study suggests that the medication may not affect the digestion of fats in humans either.

In conclusion, while Lipitor can cause digestive problems, it does not affect the digestion of all fats. The medication works by blocking the production of cholesterol in the liver and does not affect the digestion of fats in the small intestine [2]. A study published in Circulation Research suggests that atorvastatin treatment does not affect the absorption of dietary fat in rats [3].
