Lipitor is a medication used to lower cholesterol levels in the blood [1]. According to Healthline, there is no evidence to suggest that Lipitor hinders weight loss [2]. However, Medical News Today states that some people may experience weight gain while taking Lipitor, but this is not a common side effect [3]. It is important to note that weight gain can occur due to various factors, including lifestyle changes, hormonal imbalances, and other medications, and it may not be directly related to taking Lipitor. Therefore, if you are concerned about weight gain while taking Lipitor, it is recommended to speak with your healthcare provider to determine the cause and discuss potential solutions.
