Today we are looking at two disorders of the gut, irritable bowel syndrome (IBS) and diverticular disease. Both are sadly more common than ever. Irritable Bowel Syndrome symptoms range from pain in the gut, bloating, constipation and diarrhoea. This may be related to food, gut function and movement, stress and depression. The cause of IBS is not known but there is inflammation and/or infection in the gut, changes in serotonin levels and a family history in some patients with IBS.
