Is pelvic effusion 4.3*1.8 normal?

Pelvic fluid effusion of 4.3cm*1.8cm may be normal or abnormal.

1. Normal: During menstruation, a small amount of menstrual blood will flow backwards and accumulate in the pelvic cavity. During ovulation, the follicle ruptures and causes the follicular fluid to accumulate in the pelvic cavity. The peritoneum will secrete a small amount of serous fluid to reduce the friction between organs, which will also cause pelvic effusion after flowing into the pelvic cavity. These factors are normal physiological phenomena and usually do not require treatment measures. They may be gradually absorbed.

2. Abnormality: If pelvic effusion persists and is accompanied by lumbar pain or abnormal secretions, abnormal factors need to be considered, which may be related to pelvic inflammatory disease, ectopic pregnancy, corpus luteum rupture, peritoneal tuberculosis and other causes.

If you experience obvious discomfort, you need to go to the hospital as soon as possible to find out the cause. Treatment targeting the cause can help improve the symptoms. During treatment, you need to actively follow the doctor's instructions to use the medicine and don't give up halfway.
