Why does pelvic fluid accumulate?

The pelvic cavity is a very important part of women. It belongs to the internal reproductive organs and contains important reproductive organs such as the uterus, fallopian tubes, and ovaries. It can be said that the vast majority of female infertility is related to pelvic diseases. Therefore, when pelvic effusion occurs, especially if one has not given birth to a child, one is more worried that it will affect one's fertility. So, why does fluid accumulate in the pelvic cavity? Let’s take a look below.

1. Causes of physiological pelvic effusion

Some normal women will have a small amount of pelvic fluid during menstruation or ovulation. This is because the pelvic cavity is anatomically located at the lowest part of the abdominal cavity. When there is a small amount of exudate, transudate or ruptured bleeding in the pelvic and abdominal organs, the fluid will first accumulate in the pelvic cavity, thus forming pelvic effusion. For example, during menstruation, a small amount of menstrual blood can flow back into the pelvic cavity, causing pelvic effusion; the accumulation of follicular fluid in the pelvic cavity during ovulation in the middle of the menstrual period can also cause pelvic effusion; for patients with constipation, abnormal intestinal peristalsis can cause a small amount of intestinal fluid to leak out, leading to pelvic effusion.

(1) Not paying attention to hygiene during menstruation

When menstruation comes, the endometrium will fall off, the blood sinuses inside the uterine cavity will be open, and small blood clots will be present, which is very suitable for the growth of bacteria. If you do not pay attention to personal hygiene during menstruation, use unclean sanitary napkins, toilet paper, etc., or have sexual intercourse during menstruation, it provides a good opportunity for bacteria to grow and infect, causing pelvic inflammatory disease in women.

(2) When inflammation of adjacent organs spreads, women are more likely to develop pelvic inflammation when they suffer from appendicitis or peritoneal inflammation. When suffering from vaginitis and cervicitis, the inflammation will spread upward and eventually lead to pelvic inflammatory disease.

After childbirth and abortion, the body is weak and the immunity is low. The cervix is ​​in a dilated state. If personal hygiene is not paid attention to, the bacteria in the vagina and cervix may ascend and cause female pelvic infection.

(4) Infection after gynecological surgery

Artificial abortion surgery, IUD insertion (removal) surgery, salpingography (hydration), etc., if the disinfection is not strict during the operation, it is easy to get infection after the operation. If you do not pay attention to personal hygiene after surgery, do not follow the doctor's instructions for recovery treatment, or have sexual intercourse too early after treatment, it will cause bacteria to grow and lead to pelvic infection in women.

(5) Others

Ovarian and fallopian tube tumors, liver and kidney diseases can all cause pelvic effusion accompanied by ascites and even pleural effusion. Ectopic pregnancy and corpus luteum rupture can cause bloody pelvic effusion. In tuberculous pelvic inflammatory disease, the surface of the peritoneum and pelvic organs are covered with miliary tuberculosis lesions, and a large amount of exudate accumulates in the pelvic cavity.
