Thanks for contacting healthcare magic. I understand your problem.. Gastroenteritis may cause this type of symptoms. Low fiber intake in diet cause stringy stool. If this problem is long standing than think about irritable bowel syndrom. Intestinal infection by bacteria or viral or parasitic infection cause fluid stool. Celic disease may ruled out. Proper history and investigation helpful for diagnosis. Stool examinationtest is helpful for checking any infection present or not.. Consent a gastroenterologist for further diagnosis. I hope my guidance is helpful to you.. Take care. Thank you.
