Atorvastatin, commonly known by the brand name Lipitor, is a medication primarily used to lower cholesterol levels in the blood. While the sources provided do not directly address the impact of Lipitor on abdominal fat, it is important to note that one of the side effects listed by the Mayo Clinic is weight gain. Weight gain can sometimes manifest as an increase in abdominal fat. However, it is essential to consult a healthcare provider for personalized information on how Lipitor may affect abdominal fat in individual cases.
