Irritable bowel syndrome (IBS) is a common disorder affecting the large intestine that can cause symptoms such as cramping, abdominal pain, bloating, gas, diarrhea and constipation.
The condition can develop at any age, but research carried out by Bupa has revealed that most people experience their first symptoms between the ages of 20 and 30.
Additionally, it has been found that women have double the chance of reporting symptoms compared to men, and symptoms are unlikely to develop for the first time after the age of 50.
