What causes abdominal pain during the fifth month of pregnancy?

Generally, abdominal pain at five months of pregnancy may be caused by physiological reasons or pathological factors, such as uterine fibroids or threatened miscarriage. The specific analysis is as follows:

1. Physiological Causes

At five months of gestation, the fetus gradually grows larger and the uterus expands accordingly. These physiological changes can stimulate surrounding nerves and muscles, increasing physical strain and load, which may lead to abdominal pain during the fifth month of pregnancy.

2. Pathological Causes

1) Uterine Fibroids

If a woman already has uterine fibroids before pregnancy, they may exert pressure on the uterus, reducing the available space within the uterine cavity and restricting fetal development, potentially causing abdominal pain. Pregnant women are advised to strengthen health monitoring, undergo regular prenatal checkups, and closely observe any changes in the size or condition of the fibroids.

2) Threatened Miscarriage

In cases where the pregnant woman is of advanced maternal age or exposed to significant environmental pollution, oocyte quality may be affected, leading to genetic mutations in the fetus, premature rupture of membranes, and ultimately threatened miscarriage, resulting in this symptom. Treatment under medical supervision may include medications such as dydrogesterone tablets or progesterone capsules. If abdominal pain worsens and fetal malformations are confirmed, termination of pregnancy may be considered.

Besides the above, abdominal pain could also be caused by fetal demise. During the fifth month of pregnancy, women should avoid prolonged physical activity and ensure adequate rest.
