The goal of this clinical trial is to learn if statins work to prevent strictures in adults with Crohn's disease. The main question it aims to answer is:
* Can statins reduce the formation of strictures in participants with stricturing Crohn's disease?
Researchers will compare statins to a placebo (a look-a-like substance that contains no drug) to see if statins work to prevent strictures from forming. Participants will:
* Take statins or a placebo every day for 6-12 months
* Visit the clinic for lab tests twice after starting either statins or placebo
* Complete questionnaires about symptoms and medications
* Respond to monthly check-ins (via phone call) during participation
