Post-Coital Bleeding: Causes, Symptoms & When to See a Doctor

Bleeding after intercourse can have various causes, and it's crucial to consult a healthcare professional for a proper diagnosis. Some reasons why you might bleed after intercourse include:

1. Recent Physical Trauma:

- Injuries from forceful or rough intercourse can result in tearing or small abrasions to the tissues of the vagina or cervix, leading to bleeding.

2. Pregnancy-Related Changes:

- During early pregnancy, increased blood flow and dilation of blood vessels in the cervix can make them more prone to bleeding.

- Implantation bleeding, which occurs when a fertilized egg implants in the uterine wall, can also cause light bleeding around the time of a missed period.

3. Sexually Transmitted Infections (STIs):

- Certain STIs, such as chlamydia or gonorrhea, can cause irritation, inflammation, and bleeding after intercourse.

4. Hormonal Imbalances:

- Low estrogen levels or irregular hormone profiles can affect the health of the vaginal tissues, making them thinner and more susceptible to bleeding.

5. Gynecological Conditions:

- Uterine fibroids, cervical polyps, vaginal dryness, or conditions like vaginitis can also contribute to post-intercourse bleeding.

6. Menopause:

- After menopause, decreased estrogen levels may cause vaginal dryness and thinning of the tissue, leading to easier bleeding during intercourse.

7. Medications:

- Certain medications or hormonal treatments like contraceptive pills can affect the sensitivity of the vaginal tissue.

8. Uterine or Cervical Abnormalities:

- Changes in the uterus or cervix, such as a displaced intrauterine device (IUD), a condition called cervical ectropion, or cancerous changes, can also cause bleeding after sex.

If you experience bleeding after intercourse, it's important to consult a healthcare provider promptly. They can conduct examinations, tests, or scans to determine the cause and provide appropriate treatment or recommendations. Self-diagnosis and treatment should be avoided to ensure your health and safety.
