What happens if the uterus is not completely cleared after an abortion?
Incomplete uterine evacuation following induced abortion may lead to chronic abdominal pain, secondary intrauterine infection, and infertility. Specific complications are outlined below:
1. Chronic Abdominal Pain
When embryonic tissue is not fully removed from the uterus, persistent uterine contractions may occur. These contractions can cause chronic lower abdominal pain and may even result in chronic intrauterine bleeding, impaired intrauterine healing, or hemorrhagic shock.
2. Secondary Intrauterine Infection
Retained intrauterine tissue impedes the healing of injured endometrial tissue. Delayed or inadequate tissue repair increases susceptibility to local infection by pathogenic microorganisms—including bacteria and *Chlamydia*—thereby leading to secondary intrauterine infection. Common signs and symptoms include a sensation of heaviness or dull pain in the lower abdomen, irregular vaginal bleeding, and increased vaginal discharge.
3. Infertility
Incomplete uterine evacuation not only hinders proper healing and repair of the damaged uterine tissue but may also cause adhesions between the cervical canal and adjacent organs—including the fallopian tubes and ovaries—thereby reducing future conception rates and potentially resulting in infertility.
