Hello dear, The symptoms as mentioned in your post suggest that you are having Constipation, the cause of which is not certain. Along with intake of bananas, you should take fiber rich diet & maintain adequate hydration. Causes of Constipation include: 1. Functional cause- due to decreased gastric motility 2. Irritable bowel syndrome- constipation predominant type. 3. Less consumption of fiber rich foods 4. Less fluid intake 5. Prolonged use of certain medications. 6. Hormonal & Metabolic causes, etc. Though symptomatic relief can be obtained by intake of Laxatives, their regular use is not advised due to the risk of dependance & other unwanted side effects. However, as long as the underlying cause is not treated, symptoms will keep recurring. So, kindly consult a Gastroenterologist & get a proper physical examination done. Investigations like Ultrasound scan of abdomen, Colonoscopy & contrast studies will be helpful to rule out any pathology in the Gastrointestinal tract.
