According to the sources provided, Lipitor (atorvastatin) may cause digestive issues, but its effect on appetite is not mentioned. The first source, Drug Patent Watch [1], lists gastrointestinal disorders as a possible side effect of Lipitor, including nausea, diarrhea, and abdominal pain. The second source, Mayo Clinic [2], also notes gastrointestinal symptoms, such as constipation, diarrhea, and indigestion, as potential side effects of the drug. However, neither of these sources mentions any effect on appetite.

The third source, a study published in the Journal of Pharmacy and Bioallied Sciences [3], discusses the effects of atorvastatin on the liver and kidneys. The study found that atorvastatin may cause liver and kidney damage in rare cases, but again, there is no mention of any effect on appetite or digestion.

It is important to note that everyone's experience with medication can be different, and it is always best to consult with a healthcare provider if you have concerns about side effects or any other issues related to your medication.
