What is a subchorionic bleed?

A subchorionic bleed is a type of bleeding that occurs between the chorion (the outermost layer of the placenta) and the uterine wall. It is a relatively common complication of pregnancy, affecting up to 25% of women. Subchorionic bleeds can range in size from small, barely detectable bleeds to large, painful bleeds that can lead to miscarriage.

Most subchorionic bleeds are small and do not cause any symptoms. However, some women may experience the following symptoms:

* Vaginal bleeding

* Abdominal pain

* Back pain

* Nausea

* Vomiting

* Diarrhea

* Fatigue

* Dizziness

* Lightheadedness

In most cases, subchorionic bleeds resolve on their own within a few weeks. However, some bleeds can be more serious and may require treatment. Treatment for subchorionic bleeds may include:

* Bed rest

* Pelvic rest

* Avoidance of strenuous activity

* Medications to stop the bleeding

* Blood transfusions

* Surgery

In rare cases, subchorionic bleeds can lead to miscarriage. However, most subchorionic bleeds do not cause any harm to the baby and do not affect the outcome of the pregnancy.

If you are experiencing any of the symptoms of a subchorionic bleed, it is important to see your doctor right away. Early diagnosis and treatment can help to prevent serious complications.
