Dietary influences are the most common cause of stool colour variation: Green stools : leafy vegetables (spinach, kale), green food colouring Red or reddish stools : beetroot, tomatoes, red food dyes, cranberries Orange stools : foods high in beta-carotene (carrots, sweet potatoes), rifampicin (an antibiotic) Dark brown to black : iron supplements, bismuth subsalicylate, liquorice, blueberries Pale or light-coloured : primarily caused by reduced bile flow into the intestine Medications and supplements frequently alter stool appearance: Iron supplements commonly cause dark green or black stools Rifampicin and rifabutin can produce orange-red discolouration Bismuth subsalicylate causes black stools Some vitamins and herbal supplements contain pigments that pass through the digestive system Medical conditions that may affect stool colour include: Pale/clay-coloured : biliary obstruction, hepatitis, cirrhosis, pancreatic disorders Black/tarry : upper gastrointestinal bleeding (peptic ulcers, gastritis) Bright red : lower gastrointestinal bleeding (haemorrhoids, diverticular disease, colorectal pathology) Yellow/greasy : malabsorption syndromes, coeliac disease, chronic pancreatitis Green : rapid intestinal transit, certain infections Patients commencing GLP-1 therapy often simultaneously modify their diet significantly, increasing vegetable intake and reducing processed foods as part of weight management efforts
