What does a small amount of pelvic fluid mean?

Pelvic effusion is divided into mild and severe pelvic effusion according to the severity of the disease. So what does a small amount of pelvic fluid accumulation mean? This means that there is less pelvic fluid accumulation, and whether treatment is given is also related to the amount of pelvic fluid accumulation. It is generally believed that if there is less pelvic fluid accumulation, the inflammation will be milder, and if there is more pelvic fluid accumulation, the inflammation will be more serious. If a small amount of pelvic fluid is detected, you can consult your doctor whether to use medication for treatment.

We know that under normal circumstances, the peritoneum can secrete a small amount of clear fluid to reduce friction between abdominal organs. Since the "rectouterine pouch" is the lowest part of the pelvic and abdominal cavity, fluid tends to flow into this lowest point, and the capacity of this "pouch" is very small. As long as there is 2-3 ml of fluid, "fluid effusion" can be detected in the rectouterine pouch through B-ultrasound examination. In addition, female lesbians generally ovulate once a month. When the follicle ruptures, the follicular fluid is discharged into the pelvic cavity and accumulates in the rectouterine pouch, forming a few milliliters at least and more than 10 milliliters at most. Similarly, every month when menstruation comes, menstrual blood can also enter the fallopian tube from the uterine cavity, and then "flow back" into the abdominal cavity. Therefore, generally speaking, it is normal for B-ultrasound to detect 20-30mm of "fluid accumulation" in the rectouterine fossa. These "effusions" may be normal abdominal secretions, follicular fluid after ovulation, or a small amount of backflow of menstrual blood.

Of course, when there is pelvic and abdominal inflammation, the inflammation may stimulate the pelvic and abdominal peritoneum to secrete fluid, and the "rectouterine pouch" may also accumulate fluid. The amount of fluid varies. Generally speaking, the more severe the inflammation, the more fluid accumulates. For example, in tuberculous peritonitis, there may be a large amount of ascites. Other relatively rare situations include: ectopic pregnancy rupture or internal bleeding during miscarriage, which may also cause pelvic and abdominal effusion. Women who are undergoing ovulation induction therapy may also develop ascites due to ovarian hyperstimulation. Certain malignant tumors may be complicated by ascites, etc. However, in the above pathological conditions, patients often have other discomfort symptoms. For example, in case of pelvic inflammatory disease, there may be lower abdominal pain, increased leucorrhea, abnormal menstruation, and even fever. Patients with tuberculous peritonitis often have low fever, night sweats, weight loss, abdominal distension, and endoscopic effusion. Patients with ectopic pregnancy often have abdominal pain, amenorrhea, irregular vaginal bleeding, and even syncope and shock. Patients with malignant tumors often have weight loss, abdominal distension, pelvic and abdominal masses, and even cachexia.

Therefore, when you find a small amount of "pelvic fluid" during B-ultrasound examination, don't panic. First, you can judge for yourself whether you have any other discomfort. If only a small amount of "fluid" is detected in the rectouterine pouch, there is no need to be overly nervous, and there is no need to "treat" immediately. You can repeat the B-ultrasound after 1-2 months for comparison. Generally speaking, a small amount of pelvic fluid accumulation is not a disease, and a small amount of pelvic fluid accumulation can be absorbed by itself. Among women with a small amount of "pelvic effusion", a considerable proportion are healthy women without any disease.
