Hi.... Welcome to healthcare magic. As per your complain you have problem of loose stool that may be because of infection in digestive tract or lack of high fiber foods and water intake in diet or food intolerance. Do a stool sample examination test to detect any infection present or not.. If infection is present than start proper antibiotics under doctor s suggestion. Lactose intolerance or celiac disease may ruled out. Consult a gastroenterologist for further diagnosis. Detail history and investigation give exact idea about problems. I hope my guidance helpful to you.. Take care. Thank you.
