Irritable bowel syndrome (IBS) is a common gastrointestinal disorder characterized by abdominal discomfort or pain, along with changes in bowel habits. These changes can include diarrhea, constipation, or a combination of both. Symptoms may vary in intensity and duration, often triggered by stress, certain foods, or hormonal changes. While the exact cause of IBS remains unclear, factors such as abnormal muscle contractions in the intestines, heightened sensitivity to food, and bacterial imbalances in the gut may contribute. Diagnosis typically involves ruling out other conditions through medical history, physical examination, and sometimes additional tests. Management focuses on symptom relief and may include dietary modifications, stress management techniques, medication, and lifestyle changes. While IBS can significantly affect quality of life, it is not life-threatening or associated with an increased risk of serious diseases like cancer. However, it requires ongoing management and support from healthcare providers to help individuals effectively cope with symptoms.
