Is It Normal to Have Black Stool After Colonoscopy?
After undergoing a colonoscopy, it’s not uncommon to experience black stool. This usually happens because the doctor uses a substance called methylene blue during the procedure to stain polyps or other abnormalities in your colon. As you pass this substance through your digestive tract, it can temporarily turn your stool black.
The black color should fade within a few days as the methylene blue is eliminated from your system. However, if your stool remains black for more than a few days or if you experience other unusual symptoms, such as abdominal pain, fever, or nausea, it’s important to see your doctor promptly.
Possible Causes of Black Stool
Black stool can be caused by a variety of factors, including the consumption of certain foods and medications. However, it can also be a sign of more serious conditions, such as:
Upper Gastrointestinal Bleeding
Black stool can be a sign of upper gastrointestinal bleeding, which can be caused by a variety of conditions, such as ulcers, gastritis, and esophageal varices. In this case, the blood turns black as it passes through the digestive tract.
Ingesting a Black Substance
Consuming foods or medications that are black in color can also cause your stool to turn black. Some common examples include:
- Blackberries
- Licorice
- Iron supplements
Melena
Melena is a medical condition characterized by the passage of black, tarry stools. It is caused by upper gastrointestinal bleeding, and it can be a sign of a serious underlying condition.
What to Do If You Have Black Stool
