Reason behind persistent red stool
Red diarrhea, characterised by the presence of bright red blood in the stool, is often a sign of bleeding in the lower gastrointestinal tract. This article explores the common causes, symptoms, and treatment options for red diarrhea, as well as shedding light on the meanings behind other stool colours.
Red diarrhea can be caused by a variety of conditions, including hemorrhoids, anal fissures, colon polyps or tumours, diverticular bleeding, inflammatory bowel diseases (IBD), and other factors such as excessive straining, arteriovenous malformations, ulcers, or low platelet count.
Hemorrhoids, swollen blood vessels around the anus, are a common cause of red diarrhea. They are often related to constipation, straining during bowel movements, or prolonged sitting. Anal fissures, small tears in the lining of the anus, can also cause bleeding and pain during bowel movements.
Colon polyps or tumours are abnormal tissue growths in the colon that can bleed, potentially leading to red diarrhea. Diverticular bleeding, the rupture of small pouches (diverticula) in the colon, can also cause red diarrhea. IBD, such as ulcerative colitis or Crohn’s disease, can cause inflammation and bleeding in the intestines, leading to red diarrhea.
Treatment for red diarrhea depends on the underlying cause. For hemorrhoids and anal fissures, treatment often includes dietary changes to prevent constipation, sitz baths, topical medications, or procedures to reduce vein swelling. Inflammatory conditions like IBS or IBD require medications such as antispasmodics, anti-inflammatory drugs, immune modulators, or enzyme supplements. For infections causing dysentery, antibiotics like metronidazole or tinidazole are used along with supportive care such as fluid replacement. In severe or persistent cases, hospitalization with intravenous fluids and monitoring may be necessary to treat dehydration or electrolyte imbalances.
Other stool colours can provide clues about digestive health and possible underlying issues. Black or tarry stools can indicate bleeding from the upper gastrointestinal tract, certain medications or supplements, or iron. Green stools may be due to rapid transit through the intestines, certain foods or dyes, or bile presence. Pale, clay-coloured stools can indicate bile duct obstruction or liver problems affecting bile secretion. Yellow, greasy, foul-smelling stools may signal malabsorption syndromes such as celiac disease or pancreatic insufficiency.
Preventing general diarrhea involves practicing good personal and food hygiene and only drinking safe drinking water. By doing so, one can help reduce the risk of infectious diarrhea. It is important to note that red foods, such as beets, cranberries, tomato products, can also mimic blood in stool, so dietary review is crucial when evaluating red diarrhea.
