Introduction
In general, whether swelling at five months of pregnancy is dangerous depends on the nature of the swelling and accompanying symptoms. If any discomfort occurs, it is advisable to seek medical attention promptly. Avoid prolonged standing or sitting; when seated, elevate the feet to promote blood return. Wear loose, comfortable clothing and low-heeled shoes to reduce pressure on the lower limbs, and maintain a diet low in salt.

Generally, whether swelling during the fifth month of pregnancy is dangerous depends on the nature of the swelling and accompanying symptoms. If discomfort occurs, it is recommended to seek medical attention promptly. The specific analysis is as follows:

If a pregnant woman only experiences mild swelling in the ankles or lower legs around the fifth month, with symptoms more noticeable in the evening and subsiding after rest, and without elevated blood pressure, proteinuria, dizziness, or other discomforts, this is usually physiological swelling. During pregnancy, increased blood volume and uterine compression of the lower limb veins can impede blood return, leading to such swelling. This condition is not dangerous and does not affect maternal or fetal health; proper lifestyle adjustments are sufficient.

However, if the swelling spreads to the thighs, abdomen, or even the face, fails to improve with rest, and is accompanied by high blood pressure, increased foaming in urine, blurred vision, or similar symptoms, it may indicate gestational hypertension or kidney disease, which poses greater risks. Abnormal swelling suggests metabolic disturbances, and without timely intervention, it could impair placental blood supply and endanger both mother and baby.

To manage swelling, avoid prolonged standing or sitting. When seated, elevate your feet to promote circulation. Wear loose, comfortable clothing and low-heeled shoes to reduce pressure on the lower limbs. Limit dietary salt intake, consume diuretic foods such as winter melon and celery, and ensure adequate protein intake. Monitor weight daily, attend regular prenatal checkups to measure blood pressure and perform urine tests, and seek medical care immediately if swelling worsens.
