Based on the information provided, there is no direct evidence linking Lipitor specifically to worsening digestive issues over time. However, it is known that Lipitor, a type of statin medication used to treat high cholesterol, can cause various side effects, including digestive problems [2][3].

The Mayo Clinic article [2] explains that some people taking statins may experience side effects such as constipation, diarrhea, and stomach pain or cramps. These symptoms are typically mild and do not worsen over time. If digestive issues do worsen, it is essential to consult a healthcare provider, as this could be a sign of an underlying condition unrelated to Lipitor.

It is also important to note that alcohol consumption can exacerbate statin-related side effects, including digestive problems [3]. Therefore, limiting alcohol intake may help alleviate these symptoms.

In summary, Lipitor can cause digestive issues, but there is no evidence to suggest that these problems worsen over time. If digestive problems worsen or persist, it is recommended to consult a healthcare provider. Additionally, limiting alcohol consumption may help alleviate these side effects.
