Why is there blood in your bowel movement?
Blood in your bowel movement (a stool) can have various causes, ranging from minor and temporary issues to more serious conditions. Here are a few possible reasons for finding blood in your stool:
1. Hemorrhoids: Hemorrhoids are swollen and enlarged veins in the rectum or anus. Straining during a bowel movement can cause these hemorrhoids to bleed. Blood from hemorrhoids is usually bright red and may be visible on toilet paper or in the toilet bowl.
2. Anal Fissure: An anal fissure is a small tear or crack in the skin around the anus. It can occur due to constipation, diarrhea, or straining during a bowel movement. Anal fissures often cause bright red blood streaks on the stool or toilet paper.
3. Diverticular Disease: Diverticular disease is a condition where small pouches develop in the colon. When these pouches become inflamed or infected (diverticulitis), they can bleed and cause blood in the stool. The blood may be bright red or dark red, and it can be associated with abdominal pain, fever, and changes in bowel habits.
4. Inflammatory Bowel Disease (IBD): IBD is a group of conditions that cause inflammation in the digestive tract. Crohn's disease and ulcerative colitis are the two main types of IBD. Blood in the stool associated with IBD can be bright red or dark red, and it may be accompanied by abdominal pain, diarrhea, weight loss, and fever.
5. Colorectal Cancer: Colorectal cancer is a type of cancer that can occur in the colon or rectum. Blood in the stool is one of the signs of colorectal cancer, but it's important to note that not all blood in the stool is due to cancer. Blood from colorectal cancer can be dark red or black, and it may be mixed with stool or mucus. Other symptoms may include changes in bowel habits, abdominal pain, unintended weight loss, and fatigue.
6. Other Causes: Blood in the stool can also be caused by certain medications (such as aspirin or other nonsteroidal anti-inflammatory drugs), stomach ulcers, or infections in the digestive tract.
It's essential to see a doctor if you notice blood in your bowel movement, especially if it persists, is accompanied by other symptoms, or if you have risk factors for certain conditions like colorectal cancer. The doctor can evaluate your symptoms, perform tests, and determine the underlying cause of the bleeding.
