What is amniotic fluid?

Amniotic fluid is a clear, slightly yellowish liquid that surrounds and protects a developing fetus within the amniotic sac during pregnancy. It plays a crucial role in fetal development by cushioning the fetus against external pressure, allowing for movement, and aiding in the development of muscles, limbs, lungs, and the digestive system.

In the early stages of pregnancy, amniotic fluid is primarily composed of water from the parent. As the fetus grows, particularly after the 10th week of gestation, fetal urine becomes a significant component of the fluid. The fetus continuously swallows and inhales the fluid, which helps in the development of the gastrointestinal tract and lungs, and then excretes it, maintaining a dynamic balance.

The volume of amniotic fluid increases throughout pregnancy, reaching approximately 800 milliliters by the 28th week of gestation. It then decreases to around 400 milliliters at 42 weeks. Maintaining an appropriate amount of amniotic fluid is essential, as both excessive and insufficient levels can lead to complications.

Overall, amniotic fluid is vital for protecting the fetus and facilitating proper development throughout pregnancy
