Lipitor is a medication used to lower cholesterol levels in the blood [1]. While it is generally considered safe and effective, like any medication, it may cause side effects in some people. One of the most common side effects of Lipitor is digestive problems, including nausea, diarrhea, and abdominal pain [2]. However, there is no evidence to suggest that Lipitor directly affects a person's appetite.

According to the Mayo Clinic, some people may experience a loss of appetite as a result of digestive issues caused by Lipitor [2]. However, this is not a direct effect of the medication on appetite. It is more likely a result of the medication's impact on the digestive system.

A study published in the Journal of Clinical Lipidology found that Lipitor did not have a significant impact on appetite in patients with high cholesterol [3]. The study followed 53 patients over a period of 12 weeks and found that while some experienced digestive issues, none reported changes in appetite as a result of taking Lipitor.

In conclusion, while Lipitor may cause digestive issues in some people, there is no evidence to suggest that it directly affects a person's appetite. If you are experiencing changes in appetite or any other side effects while taking Lipitor, it is important to speak with your doctor. They may be able to adjust your dosage or recommend alternative medications.
