What causes lower abdominal pain after miscarriage?

Generally, "lower abdominal pain" refers to discomfort in the lower abdomen. After a miscarriage, lower abdominal pain may be caused by uterine contractions, physical recovery, constipation, postoperative infection, cervical adhesion, or other reasons. If discomfort occurs, it is recommended to seek medical attention promptly. Specific causes are analyzed as follows:

1. Uterine Contractions

After a miscarriage, the uterus undergoes a series of recovery processes. It contracts to reduce bleeding and help expel any remaining tissue from the uterine cavity. In most cases, pain caused by uterine contractions does not require special treatment and can be relieved through rest and application of heat packs.

2. Physical Recovery

Following a miscarriage, hormonal levels in the body change, and the uterus gradually returns to its non-pregnant state. Mild pain may occur during this physiological adjustment process. Maintaining a healthy diet and adequate nutritional intake can help accelerate recovery.

3. Constipation

Reduced physical resistance and medication side effects after a miscarriage may lead to constipation. Slowed intestinal motility can cause abdominal pain, possibly accompanied by symptoms such as nausea. Treatment under medical guidance may include medications such as Bifidobacterium Tristrain Live Capsules, Lactobacillus tablets, or Enteric-coated Clostridium butyricum capsules.

4. Postoperative Infection

After a miscarriage, the uterus and vagina remain in an open state and are susceptible to bacterial or other pathogenic infections, which may cause abdominal pain along with symptoms such as fever, increased vaginal discharge, and foul odor. Treatment under a doctor's advice may include medications such as Metronidazole tablets, Azithromycin capsules, or Cefradine capsules.

5. Cervical Adhesion

Injury or infection to the cervical canal after a miscarriage may lead to cervical adhesion, preventing menstrual blood from being discharged normally and causing abdominal pain. This may be accompanied by symptoms such as amenorrhea (absence of menstruation) or reduced menstrual flow. Under medical guidance, cervical dilation surgery may be performed to separate the cervical muscle and connective tissues, allowing menstrual blood to flow out normally.

In daily life, adjusting diet, increasing dietary fiber intake, maintaining external genital cleanliness and dryness, avoiding sexual intercourse and tub baths, ensuring adequate rest, and engaging in mild physical activities such as walking can help promote physical recovery.
