What is the normal amount of free pelvic fluid?

The pelvic cavity is a tissue of the uterus. Under normal conditions, there is a certain amount of fluid accumulation in this tissue. The content of this fluid is about 10mm and it is absorbed by itself during the menstrual period. Moreover, during the ovulation period and the menstrual period, the pelvic fluid accumulation will continue to increase. This is a normal physiological phenomenon. However, if there is too much pelvic fluid accumulation at other stages, it will cause infertility and pelvic inflammatory disease symptoms in women.

When female friends go to the hospital for a gynecological examination and see the term "pelvic free fluid" on the examination report, they usually have questions and don't know what it means. In fact, it refers to pelvic effusion.

How much pelvic fluid is normal?

Under normal circumstances, physiological pelvic fluid accumulation of less than 10 mm may occur during ovulation and early pregnancy. This is normal and can usually be absorbed by itself within one or two months.

Except during ovulation and early pregnancy, any accumulation of fluid is mostly pathological and requires active treatment. Patients with less effusion should be treated as early as possible. Most pelvic effusions are caused by inflammation, that is, by exudate from chronic pelvic inflammation. A few cases are caused by ectopic pregnancy rupture, corpus luteum rupture, pelvic abscess, chocolate cyst, and ovarian cancer.

Whether it is pelvic effusion is not determined by the amount, but mainly by whether it is physiological effusion or inflammatory effusion. Therefore, if pelvic effusion occurs, you should go to the hospital for examination in time to avoid delaying the disease and missing the best time for treatment.

Causes of pelvic effusion

Pelvic effusion refers to the presence of inflammatory exudate in the pelvic cavity. It can occur after the endometrium becomes inflamed. It is a slightly viscous fluid that exudes from the swollen cells of the endometrial tissue and is gradually wrapped by the surrounding tissue to form a cystic mass. If left untreated, it can grow slowly. If it is too large, medication cannot eliminate it and surgery is required to remove it. So what is the cause of pelvic effusion? Let’s take a look with the editor below~

1. Infection after gynecological surgery: When female friends undergo some artificial surgery, IUD insertion surgery, hysterosalpingography, etc., if the disinfection during the operation is not very strict, it is easy to cause infection problems for women after the operation. Moreover, if women do not pay attention to their personal hygiene after surgery, do not follow the doctor's instructions for recovery treatment, have sexual intercourse too soon after treatment, etc., these will cause bacteria to continue to grow and lead to pelvic infection in women, causing pelvic inflammation in women. Therefore, female friends must pay attention to personal hygiene during surgery to avoid infection.

2. Spread of inflammation in adjacent organs: Some female friends may suffer from appendicitis or peritoneal inflammation, and the female reproductive organs are nearby. If the inflammation is not treated in time, it can easily spread and eventually lead to inflammation in the female pelvic area.

3. Not paying attention to hygiene during menstruation: When women have their period, the endometrium will fall off, so the blood sinuses inside the uterine cavity will be open and there will be coagulated blood clots, which is very suitable for the growth of bacteria. Therefore, if female friends do not pay attention to their personal hygiene during menstruation, or do not use standard sanitary napkins, toilet paper, etc., or have sexual intercourse during menstruation, it provides a good opportunity for bacterial growth and infection, which will cause female pelvic inflammatory disease.

4. Postpartum and post-abortion infection: After childbirth and artificial abortion, women’s bodies have suffered a lot of damage, so their bodies are very weak, and their body resistance and immunity are relatively low. At this time, the female cervix is ​​also in a state of expansion. If you do not pay attention to personal hygiene at this time, all the bacteria in the vagina and cervix may continue to ascend and cause female pelvic infection.
