What Is Amniotic Fluid & Why Does It Matter?
Amniotic fluid is the transparent liquid that covers your baby inside the womb. Once you conceive, the fluid formation starts, and by the second trimester, it becomes one of the most crucial parts of your baby's environment.
This fluid helps your baby:
- Practice swallowing and breathing
- Stay active to keep your muscles and bones strong
- Stay protected from pressure or sudden movement
- Maintain a steady temperature
Why Do Doctors Examine Fluid Levels Through Scans?
Is it possible to detect fluid levels without a scan?
No. You might feel bloated, heavy, or notice a big womb, but these signs don't confirm actual fluid levels. That's why doctors use ultrasound scans, which are the safest and most accurate method for checking amniotic fluid.What do scans show that symptoms can't?
- Whether the fluid is too high (polyhydramnios)
- Whether the fluid is too low (oligohydramnios)
- Whether your baby is moving properly
- If the placenta is well-functioning
- How fluid changes as your pregnancy progresses
How Do Scans Measure the Fluid?
You may hear your physician talking about two common methods:
1. Amniotic Fluid Index or AFI
The scan divides your womb into four segments and measures each. A standard AFI is usually 8-18 cm.2. Single Deepest Pocket or SDP
This measures the deepest visible pocket of fluid. A normal SDP is 2-8 cm.These methods are painless and hardly take any time, and they offer valuable insights into your baby's health.

How can low fluid impact your baby?
Your baby might not have enough room to move due to low fluid. This can impact lung development, muscle growth, and overall comfort.What to expect now?

What If the Fluid Is Too High?
