![]() ![]() In contrast, the presence of excess amniotic fluid is referred to as polyhydramnios. When there is not enough amniotic fluid the condition is referred to as oligohydramnios. The ratio of amniotic fluid to fetal volume increases until about 30 weeks of gestation and then appears to decline. During the first half of pregnancy, the amniotic fluid volume is closely correlated with fetal weight. 1 There are certain medical complications involving the amount of amniotic fluid during gestation. After this point, the amniotic fluid volume declines at a rate of 8 per week. ![]() At birth, there is about 1L of amniotic fluid. And by the 28th week, it plateaus to 800 mL. In humans, it increases from approximately 25 mL to 400 mL from the 10th week to the 20th week of gestational age. The volume of the amniotic fluid increases as the fetus develops and grows. Thus, the amniotic fluid is initially composed of water and electrolytes and later (about 12th -14th week) it contains proteins, lipids, carbohydrates, phospholipids, and urea. By 16th week of gestational age, the fetus contributes to the amniotic fluid through excreting urine. When your water breaks (a sign of labor ), your amniotic sac breaks and amniotic fluid leaks from your vagina. The amniotic sac forms around 12 days after you become pregnant. The fetus grows inside an amniotic sac filled with amniotic fluid during pregnancy. It is formed from the maternal plasma and then passes through the fetal membranes. Amniotic fluid is a water-like substance surrounding the fetus in your uterus. ![]() The amniotic fluid is contained within the amniotic sac. It is said to be protective since it provides an environment that cushions the baby from injury and plays an important role in fetal development. It protects your baby and helps in its development. The amniotic fluid, also called pregnant female’s water(s) is the fluid surrounding the developing fetus within the amniotic sac. Amniotic fluid is the liquid that surrounds and cushions your baby in the womb. The protective fluid surrounding the developing fetus within the amniotic sac of a pregnant female ![]()
