Hi.. Thanks for contacting HCM for health query. You have a month of diarrhoea ,almost every day this month and the last stool was green and you are worried whether you have a threatening problem. Madam do not worry. Green stools are because of bilious nature means movement of bowel is more and green stool can occur after taking food rich in greens. But since diarrhoeal episode is for a month kindly get a personal opinion from a physician and undergo investigation like motion complete,ultrasound scan abdomen,complete blood count,thyroid profile etc..and follow his advice Till then include natural probiotics like curd,replinish yourself with plenty of fluids like tender coconut water and fresh fruit juices with no added sugar
