Crohn's disease cannot be prevented because the cause is unknown. However, you can take steps to reduce the severity of the disease.

• Medicines taken regularly may reduce sudden (acute) attacks and keep the disease in remission (a period without symptoms).
• Most experts recommend acetaminophen (Tylenol, for example) for pain relief rather than nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen. NSAIDs have been linked to flare-ups.³
• Do not smoke. Smoking makes Crohn's disease worse.
• Cut down on the amount of sugar and processed foods you eat, such as packaged sweets and snacks.
• Eat a healthy diet.
• Never use antibiotics unless they have been prescribed for you by a doctor.
• Get regular exercise.
