Blood in the stool can be concerning, whether it’s discovered while wiping after a bowel movement or from a test ordered by your doctor. In some cases, it may indicate a serious medical condition.
But it’s important to keep in mind that not all cases of bloody stool are cause for alarm. The presence of blood in the stool (otherwise known as hematochezia) can be the result of many different conditions, ranging from minor to serious.
In some cases, it could be caused by an infection, an ulcer, a polyp, or an inflammatory bowel disease. It can also be caused by something as benign as a hemorrhoid or an anal fissure due to straining during a bowel movement.
In some cases, the cause may be unknown. If you discover blood in your stool, it’s important to talk to your doctor. Your doctor can help you determine the cause and the most appropriate treatment.
Depending on the cause, treatment may include antibiotics, dietary changes, medications, or surgery. Your doctor will likely ask you several questions about your health, your symptoms, and your lifestyle.
It’s important to answer honestly and thoroughly, so your doctor can get a clear picture of what’s going on. It’s also important to provide your doctor with a sample of your stool that can be tested for blood, so they can assess the cause and determine the best course of treatment.
Blood in Stools: Possible Causes
Blood in the stool can be a cause for concern, but it’s important to remember that not all cases of bloody stools are serious. If you discover blood in your stool, it’s important to talk to your doctor for an accurate diagnosis and to get the proper treatment.
The most common causes of blood in the stool include:
- Anal fissures – A fissure is a tear in the lining of the rectum or anus. These can be caused by straining during a bowel movement or from chronic constipation.
- Gastrointestinal (GI) infections – Bacterial, viral, and parasitic GI infections can all cause bloody stools.
- Ulcers – Peptic ulcers can be caused by a bacterial infection, long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), or a result of other conditions such as Crohn’s disease or inflammatory bowel disease.
- Colorectal cancer – While colorectal cancer is rare in young people, it is still a possible cause of blood in the stool.
- Hemorrhoids – Hemorrhoids are swollen veins in the anus or rectum and can be caused by straining during bowel movements, chronic constipation, pregnancy, or obesity.
- Polyps – Polyps are noncancerous growths in the lining of the large intestine.
When to See a Doctor
If you find blood in your stool, you should see your doctor as soon as possible to determine the cause and receive treatment if necessary. Your doctor may order blood tests, a stool sample, or a colonoscopy to help diagnose and treat the condition. If you experience other symptoms such as abdominal pain, cramping, diarrhea, or weight loss, you should see your doctor for further evaluation.
Preventing Blood in the Stool
The best way to prevent blood in the stool is to practice good bowel habits. This includes eating a high-fiber diet, drinking plenty of fluids, and getting regular exercise. Pay attention to changes in your stools and discuss any concerns with your doctor.
Blood in the stool can be concerning, but it doesn’t always signal a serious health problem. By understanding the possible causes and taking steps to maintain good bowel habits, you can help prevent and treat any issues that arise.
