Blood on the surface of the stool is common with hemorrhoids or injuries to the rectal or anal area. This can also be accompanied by painful bowel movements. Alopecia, or hair loss, is not likely to be related to blood on the stool but may be present at the same time due to unrelated causes. Contact your doctor if you have bleeding in the stool so you can determine the cause.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
An anal fissure is a small tear or cut in the skin lining of the anus. Pain and/or rectal bleeding during bowel movements are common symptoms of anal fissures. Treatment includes increasing liquid intake, using stool softeners, prescription medications, and surgery.
Hemorrhoids (piles) are swollen veins in the rectum and anus. Causes include pregnancy, obesity, diarrhea, low-fiber diet, and prolonged sitting on the toilet. Treatment varies depending upon the severity of the hemorrhoids. Some treatment options include over-the-counter creams and suppositories, stool softeners, warm sitz baths, and hemorrhoidectomies.
Constipation is defined medically as fewer than three stools per week and severe constipation as less than one stool per week. Constipation usually is caused by the slow movement of stool through the colon. There are many causes of constipation including medications, poor bowel habits, low fiber diets, laxative abuse, and hormonal disorders, and diseases primarily of other parts of the body that also affect the colon.
Drug interactions occur frequently. Get facts about the types of drug interactions, what substances or other things that may interact with drugs such as OTC drug and prescription drugs, vitamins, food(s) (grapefruit), and laboratory tests.
