My grandmother is facing continuously loose stools. Not on daily basis but 2-4 days a week(4-5 times a day). She got admitted in a multi speciality hospital and inspected by gastro doctors but nothing was found abnormal . All diagnosis done ,including endoscopy. Everything found to be normal. They said she is fine completely. Unable to find the cause of it.. recently my father (her son) and my grandfather (her husband) passed away. Can it also be a mental health problem??
