Bleeding caused by diverticulosis typically heals on its own, but in instances where a significant amount of blood loss has occurred, it may be necessary to have a blood transfusion or medicinal injections, according to WebMD. In more severe cases, surgery may be necessary to remove the infected areas of the colon that are causing the issue.
When a patient develops pouches in the wall of the large intestine, this leads to a condition called diverticulosis, according to WebMD. When these pouches rupture, they can bleed, causing sudden blood in the stools. While the condition often heals itself, any evidence of blood in stools should be treated and examined by a medical professional, especially since alarge amount of blood loss is possible and itcan cause the patient to experience lightheadedness ordizziness.
Diverticulosis can occur when excess pressure is exerted on the intestinal wall. The issue can be prevented by consuming a high fiber diet. Diets low in fiber cause the stools to be hard and small, making the colon exert more pressure to move the stools through the intestinal tract. Small, hard stools also sit in the intestines for a longer period of time, increasing pressure against the intestinal wall. A high fiber diet produces bulkierstools that move more easily and quickly through the colon.
