Overview

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder affecting the large intestine. It is characterized by recurrent abdominal discomfort associated with altered bowel habits. IBS does not cause structural damage to the intestines. Symptoms may fluctuate over time and vary in intensity. The condition is common and can significantly affect daily activities. It may present with diarrhea, constipation, or alternating patterns. IBS is considered a chronic condition requiring long-term management. Stress and dietary factors often influence symptoms. Although uncomfortable, IBS does not increase the risk of serious bowel disease. Early diagnosis helps improve quality of life.

What Happens During Allergic Rhinitis?

In IBS, the normal movement of the intestines becomes irregular. The bowel muscles may contract too strongly or too weakly. This disrupts normal digestion and bowel movements. Increased sensitivity of intestinal nerves may cause abdominal pain and bloating even without visible inflammation.

Diagnosis

Diagnosis is based on symptom patterns and exclusion of other conditions. Doctors use criteria such as recurrent abdominal pain associated with bowel changes. Blood tests and stool tests may be performed to rule out infections or inflammatory disorders. Colonoscopy may be recommended in certain cases.
