Hand edema in the seventh month of pregnancy may be related to high estrogen levels, increased blood volume during pregnancy, and uterine compression of the abdominal veins.
1. High estrogen level: Estrogen level rises in pregnant women’s bodies after pregnancy, and high estrogen level can lead to sodium retention in the body, resulting in edema of the hands.
2. Increase in blood volume during pregnancy: blood volume increases by 20-30% during pregnancy compared to non-pregnancy period, and the increased blood volume can lead to an increase in the negative pressure of the circulatory system, resulting in the exudation of tissue fluids, inducing tissue edema, which can lead to edema in the hands in the seventh month of pregnancy.
3. uterine compression of the abdominal veins: in late pregnancy, the uterus increases in size can produce pressure on the intra-abdominal veins, resulting in blood reflux obstruction, the phenomenon of seven months pregnant with swollen hands.
Swollen hands in the seventh month of pregnancy may also be associated with hand infections, hand trauma, rheumatoid arthritis and other causes, should be timely to the hospital, clear cause to give targeted treatment.
