Reasons of Free Fluid in the Pelvic Cavity

Q: My daughter’s age is 7. Ultrasound detected a small pocket of anechoic free fluid in pelvic cavity. Doctor gave some medicine and told nothing to worry. She took medicine for 5 days only. Is the fluid destroyed by that medicine?


Free fluid in the pelvic cavity may be caused by inflammation of any organ in the pelvic region. This may be the intestines or any reproductive organ (ovary/uterus.)

Another cause of fluid includes trauma in the pelvic region. 

Perhaps your doctor wants to give it time. Most of the inflammations reduce by themselves. The medicines may be for symptomatic treatment only. 

The medicine cannot dry the fluid. Our body itself dries it up with time. 

Take Care,

      As you may read above, free fluid in the pelvis is caused due to inflammation of some pelvic organ. This is commonly some infection.

      Investigations are required to detect the exact cause. If infection is detected, appropriate antibiotics are given.
