I have been having abnormal stools and bowel habits for about 6 months. The bowel motions are not well formed, soft to loose, clay coloured and sticky, sometimes loose and explosive and of offensive odour. It gives me a sense of incomplete clearance and sticky bottom and I have to brush the toilet bowl every time. I go once daily or on alternate days. I feel well and have a good appetite. I eat good food with plenty of fibres and drink plenty of fluids, especially water. I lead an active life. My blood tests show normal results, including liver function tests. Normal colonoscopy and abdominal CT scan showing normal Liver and Pancreas. Any suggestion?
