Treating blood in the stool depends on the cause of the problem, as explained by Healthline. Doctors stop immediate bleeding before diagnosing and addressing the cause to prevent additional bleeding, according to WebMD.
Treatments for blood in the stool may involve simple things that patients can do on their own, as WebMD notes. These include consuming foods that are rich in fiber to reduce constipation, which aggravates anal fissures and hemorrhoids. The patient may also sit in a warm or hot bath to relieve the fissures and stop the bleeding.
Doctors may prescribe medication and antibiotics to treat the cause of the bleeding, explains WebMD. Hemorrhoidal creams relieve hemorrhoids, stool softeners reduce constipation and antibiotics treat H. pylori bacteria, which all cause blood in the stool. Anti-inflammatory drugs may treat colitis, and other medications can suppress acid in the stomach.
In cases of moderate or severe bleeding, doctors perform a colonoscopy to determine the location of the bleeding in order to stop it immediately, according to MedicineNet, and if the cause is diverticular bleeding, a colonoscopy determines which diverticulum is bleeding so that surgeons can remove it. Other treatment options include snaring bleeding polyps or surgically removing parts of the colon that have been damaged by inflammatory bowel syndrome and cancer, as explained by WebMD.
Cauterization stops the bleeding caused by postpolypectomy and angiodysplasias ulcers or the bleeding from blood vessels inside the diverticula, explains MedicineNet. If doctors identify a bleeding blood vessel as the cause of blood in the stool, they may infuse medication through an angiographic catheter to constrict the blood vessel and stop the bleeding. He may also infuse microscopic coils through the catheter to embolize or plug the bleeding blood vessels.
