Overview

Both IBS and Crohn's Disease can cause abdominal pain, diarrhea, and changes in bowel habits, making them difficult to distinguish without medical evaluation. While IBS is a functional disorder that doesn't cause physical damage to the digestive tract, Crohn's disease is an inflammatory condition that can cause tissue damage and complications.

Disease Summaries

IBS: It is a condition with recurring episodes of abdominal discomfort, diarrhea, and constipation. IBS (irritable bowel syndrome) is diagnosed when no clear cause can be found despite investigations. The exact cause of IBS is unknown, but stress and certain foods are known to cause flare-ups.

Crohn's Disease: It is an inflammatory condition of the gut. It is part of a group of diseases known as inflammatory bowel disease or IBD. It can affect anywhere from the mouth to the anus (end of the bowel).The exact cause is not well known.

Treatment Approaches

IBS Treatment Approaches

Treatment involves dietary modifications to identify and avoid trigger foods, stress management techniques, and medications to control specific symptoms like diarrhea or constipation. Probiotics and fiber supplements may be helpful for some patients. Psychological support through cognitive behavioral therapy can help manage stress-related symptoms.

Crohn's Disease Treatment Approaches

Treatment includes anti-inflammatory medications, immune system suppressors, and biologics to control inflammation and prevent flare-ups. Nutritional support and dietary modifications play a crucial role in management. Surgery may be needed for complications, and lifestyle changes such as stress management and smoking cessation are important for maintaining remission.
