What reason is pregnant 3 months amniotic fluid little

First: fetal malformations such as congenital absence of kidney, renal hypoplasia, ureteral or urethral stricture and other malformations lead to oligohydramnios or anuria.

Second: prolonged pregnancy, prolonged pregnancy, placental dysfunction, inadequate perfusion, fetal dehydration, resulting in oligohydramnios. Some scholars believe that when the fetus is over mature, the sensitivity of renal tubules to antidiuretic hormone is increased, and the amount of urine is less, resulting in oligohydramnios. The incidence of oligohydramnios caused by prolonged pregnancy is 20% - 30%.

Third: oligohydramnios is one of the characteristics of intrauterine growth retardation (IUGR). Chronic hypoxia causes redistribution of fetal blood circulation, which mainly supplies the brain and heart, while renal blood flow decreases and fetal urine production decreases, resulting in oligohydramnios.
