Abnormal Vaginal Bleeding After C-Section: Causes and Solutions - Obstetrics and Gynecology

Vaginal bleeding


Five months ago, I had a cesarean section and did not breastfeed.
My menstrual cycle returned to normal after a little over two months, but I have been experiencing bleeding outside of my menstrual period.
Initially, the blood was light red and had a slight odor, but it has now changed to a dark brown color.
Occasionally, I feel a dull ache in my lower abdomen.
This has been ongoing for three to four months.
I have seen an obstetrician-gynecologist three times and a traditional Chinese medicine practitioner four times, but there has been no improvement.
Can you please tell me what might be wrong?

Hello, after giving birth, it is common to experience irregular menstruation.
If it does not improve, it is generally recommended to consult an obstetrician-gynecologist for menstrual regulation.
Wishing you good health.

More Info


Abnormal vaginal bleeding after a cesarean section (C-section) can be concerning, especially when it persists for several months. Given your history of a C-section five months ago, it’s essential to consider various potential causes for this bleeding, especially since you mentioned that your menstrual cycle had returned to normal after the initial postpartum period.


Possible Causes of Abnormal Bleeding
1. Hormonal Imbalances: After childbirth, your body undergoes significant hormonal changes. If you are not breastfeeding, your estrogen and progesterone levels may fluctuate, leading to irregular bleeding. This can manifest as spotting or bleeding outside of your regular menstrual period.

2. Retained Products of Conception: Sometimes, after a C-section, remnants of the placenta or other tissues can remain in the uterus. This can lead to ongoing bleeding and may require medical intervention to remove these retained products.

3. Infection: Postpartum infections can occur, particularly if there were any complications during the C-section. Symptoms may include unusual discharge, fever, and persistent abdominal pain. If there is an infection, it may require antibiotics for treatment.

4. Uterine Atony or Subinvolution: After delivery, the uterus should contract and return to its normal size. If it does not contract effectively, it can lead to prolonged bleeding. This condition is known as uterine atony or subinvolution.

5. Cervical or Vaginal Issues: Sometimes, the cervix or vaginal walls can sustain minor injuries during delivery or from other activities. These injuries can lead to bleeding, especially if there is irritation or infection.

6. Endometrial Issues: Conditions such as endometrial polyps or fibroids can develop and cause abnormal bleeding. These growths can be benign but may require monitoring or treatment if they cause significant symptoms.

7. Pelvic Inflammatory Disease (PID): If there is an infection in the reproductive organs, it can lead to PID, which may cause abnormal bleeding along with pain and other symptoms.


Recommended Actions
Given that you have already consulted with healthcare professionals multiple times without improvement, it may be beneficial to consider the following steps:
1. Further Evaluation: Request a comprehensive evaluation, including a pelvic ultrasound, to check for any retained products, fibroids, or other abnormalities in the uterus and ovaries.

2. Hormonal Assessment: A hormonal panel can help determine if there are any imbalances contributing to your symptoms.

3. Infection Screening: If not already done, tests for infections, including sexually transmitted infections (STIs), should be considered.

4. Consult a Specialist: If your current healthcare providers have not provided satisfactory answers, consider seeking a second opinion from a gynecologist who specializes in postpartum care or reproductive health.

5. Monitor Symptoms: Keep a detailed record of your bleeding patterns, any associated symptoms (like pain or discharge), and any changes in your overall health. This information can be invaluable for your healthcare provider.


Conclusion
Abnormal bleeding after a C-section can stem from various causes, and it’s crucial to identify the underlying issue to receive appropriate treatment. While some causes may resolve on their own, others may require medical intervention. Given your ongoing symptoms, I strongly encourage you to pursue further evaluation to ensure your health and well-being. Remember, your concerns are valid, and seeking clarity on your health is essential.
