What causes mild abdominal pain in the late stages of pregnancy?

In general, mild abdominal pain during the late stages of pregnancy may be caused by uterine enlargement, false labor contractions, fetal head descent, fetal movement, or signs of impending labor. If discomfort occurs, it is recommended to seek medical attention promptly. A detailed analysis is as follows:

1. Uterine Enlargement

As the pregnancy progresses into the later stages, the fetus gradually grows and the uterus expands accordingly. This expansion may stretch surrounding nerves, muscles, or ligaments, causing pregnant women to experience a mild, dull pain. This is a normal physiological phenomenon. Avoid standing or sitting for prolonged periods; change body positions appropriately.

2. False Labor Contractions (Braxton Hicks Contractions)

False labor contractions commonly occur in late pregnancy. During these episodes, the uterine muscles become sensitive and may contract in response to stimulation, leading to mild abdominal pain. This type of pain is usually irregular, varies in intensity, and lasts for a short duration. It can typically be relieved with adequate rest.

3. Fetal Head Descent

In late pregnancy, the fetal head gradually descends into the pelvis in preparation for delivery. During this process, the fetal head may compress nerves or tissues within the pelvis, causing abdominal pain. Maintain sufficient rest and avoid strenuous physical activity.

4. Fetal Movement

As the fetus grows and develops, movements become more frequent and stronger, which may cause pregnant women to feel mild abdominal discomfort. Pay attention to fetal movements, monitor them regularly, and ensure that fetal activity remains normal.

5. Signs of Impending Labor

In late pregnancy, if a pregnant woman experiences mild abdominal pain accompanied by regular uterine contractions, increasing pain, or increased vaginal discharge, these may be signs of approaching labor. In such cases, she should go to the hospital promptly for delivery and follow the doctor’s recommendations regarding the appropriate mode of childbirth.

In daily life, pregnant women should undergo regular prenatal checkups, maintain good dietary hygiene, avoid raw, cold, spicy, or greasy foods, and refrain from intense physical activity.
