Final answer:
Medications, especially anti-inflammatory and immune-suppressing drugs, are effective in maintaining remission in Crohn's disease, supplemented by lifestyle changes and diet modifications.
Step-by-step explanation:
Medications are effective in inducing and maintaining remission in moderate to severe Crohn's disease. While no medications or surgical procedures can cure Crohn's disease, certain drugs such as anti-inflammatory or immune-suppressing drugs help alleviate symptoms and maintain remission.
Additionally, lifestyle changes including diet modifications and smoking cessation can control symptoms and reduce flare-ups. In some cases, surgery may be necessary to address complications such as bowel obstructions or abscesses.
