How does pregnant one leg swell to return a responsibility?
First: after pregnancy, the blood volume of pregnant women gradually increased from the 6th week of pregnancy, reached the peak at the 34th week, and maintained at this level until two weeks after delivery. Blood volume can be increased by about 40% compared with non pregnancy period, so after the increase of blood volume, interstitial fluid will also increase.
Second: as the increase of blood, the increase of plasma is more than the increase of blood cells, so the blood components will be relatively diluted, and the relative concentration of plasma albumin is also lower than that during non pregnancy. Plasma albumin is the main component to maintain plasma osmotic pressure. The plasma osmolality during pregnancy is lower than that during non pregnancy. This makes the water in the blood flow easy to penetrate into the interstitial fluid, resulting in lower limb edema.
Third: after pregnancy, the uterus increases, so that the pelvic pressure increases, so that the lower extremity venous blood flow is affected. This is also one of the important causes of lower limb edema. If the edema during pregnancy is lighter after rest or sleep, it is physiological and need not be worried.
matters needing attention
1. Rest. People who are engaged in long standing and sedentary work will have serious edema. Expectant mother had better work every 1 hour, rest 10 ~ 15 minutes, change posture, exercise legs. 2. Raise your legs. Raising legs for 15-20 minutes before going to bed (or during lunch break) can accelerate blood return and reduce venous pressure. It can not only relieve edema during pregnancy, but also prevent varicose veins of lower limbs and other diseases.
