Bowel movement issues


Hello doctor, I would like to ask if it is normal for menstrual blood to stick to the toilet bowl during bowel movements, or could it possibly indicate a gastrointestinal issue? (Attached is an image)

Dr. Zhang Shuhao reply Surgery


You can wait until the menstrual period ends to see if there is any continued bleeding, observing the amount and color of the bleeding, as well as any accompanying pain or abdominal symptoms.
If the bleeding persists, it is recommended to consult a gastroenterologist or a colorectal specialist for examination.

More Info


Seeing menstrual blood on the toilet walls during a bowel movement can be concerning, but it is not uncommon. Menstrual blood can sometimes be expelled in ways that may seem unusual, especially if you are experiencing a heavier flow or if you are straining during a bowel movement. Here are some important points to consider regarding this situation.

1. Menstrual Flow: During menstruation, the body sheds the lining of the uterus, which is composed of blood and tissue. If you are on your period and notice blood on the toilet walls, it could simply be a result of the menstrual flow. This is particularly true if you are using the restroom while menstruating, as the blood can mix with other bodily fluids and may splatter.

2. Bowel Movements: Straining during a bowel movement can increase the likelihood of blood being expelled from the vagina. If you are experiencing constipation or difficulty passing stool, this could lead to increased pressure in the pelvic area, which might cause menstrual blood to be expelled more forcefully.

3. Hormonal Changes: Hormonal fluctuations during your menstrual cycle can also affect the consistency and flow of menstrual blood. Some women may experience heavier bleeding or clotting, which can lead to more noticeable blood during bowel movements.

4. Potential Gastrointestinal Issues: While it is less likely, if you are experiencing other gastrointestinal symptoms such as pain, diarrhea, or changes in bowel habits, it may be worth consulting a healthcare professional. Conditions such as endometriosis can cause menstrual blood to appear in unusual places, including the rectum, especially if there are adhesions or lesions present.

5. When to Seek Medical Attention: If you notice any of the following, it is advisable to seek medical attention:
- A significant increase in menstrual flow or changes in your cycle.

- Severe pain during menstruation or bowel movements.

- Blood that appears to be coming from the rectum rather than the vagina.

- Any other unusual symptoms such as fever, chills, or significant changes in your health.

6. Consulting a Healthcare Provider: If you are concerned about the amount of blood or any associated symptoms, it is always best to consult with a healthcare provider. They can perform a thorough evaluation, which may include a pelvic exam, ultrasound, or other diagnostic tests to rule out any underlying conditions.

In summary, while it is not unusual to see menstrual blood on the toilet walls during your period, especially if you are straining, it is important to monitor your overall symptoms. If you have any concerns or experience significant changes in your menstrual cycle or bowel habits, do not hesitate to reach out to a healthcare professional for guidance. They can provide you with the necessary support and treatment options to ensure your health and well-being.
