The effects of Lipitor (atorvastatin) on hunger can vary from person to person, but some individuals may experience changes in their appetite while taking the medication [1]. According to the prescribing information, Lipitor can cause changes in liver function, which may be associated with altered appetite and food cravings [2].

A few studies have investigated the relationship between statin medications, including Lipitor, and appetite changes. One study published in the Journal of Clinical Endocrinology and Metabolism found that statin use was associated with increased hunger and appetite in some patients [3]. However, the same study noted that the magnitude of the changes was generally small and may not be clinically significant.

Another study published in the Journal of General Internal Medicine found no significant difference in appetite or food intake between patients taking atorvastatin (Lipitor) and those taking a placebo [4]. Additionally, a review of statin medications published in the journal Circulation noted that some patients may experience gastrointestinal side effects, including changes in appetite, while taking statins, but these effects are generally mild and temporary [5].

It is essential to note that individual experiences with Lipitor and hunger may vary. If you are taking Lipitor and notice changes in your appetite or hunger, it is best to speak with your healthcare provider about your concerns. They can assess your individual situation and provide guidance on how to manage any potential side effects.
