The medical abbreviation IBS stands for Irritable Bowel Syndrome, which is a common functional gastrointestinal disorder. IBS is a chronic condition that affects the large intestine, causing symptoms such as abdominal pain, bloating, constipation, and diarrhoea. The exact cause of IBS is unknown, but it is thought to be related to abnormal muscle contractions in the intestine and sensitivity to certain foods or stressors.
IBS is a diagnosis of exclusion, meaning that other conditions that could be causing the symptoms must first be ruled out. Treatment for IBS may involve lifestyle changes such as changes to diet, stress management techniques, and regular exercise. Medications may also be used to manage symptoms such as pain, diarrhoea, or constipation.
