Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have symptoms of constipation and weakness which occurs due to eating a lot of dairy products, irritable bowel syndrome, some medications like antidepressants, acidity and lack of fibres in diet. Need not to worry. I would suggest you to consult gastroenterologist for proper examination. Doctor may order colonoscopy or other tests to look for blockages in your colon , barium studies and blood test for hormonal changes. Doctor may prescribe fiber supplement. You should take plenty of fluids and take diet rich in green leafy vegetables. For now drink lot of water , do light exercises and avoid fatty and heavy meals. You can start with the course of osmotic laxatives , stool softeners and medicine to reduce acidity. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
