What causes pelvic fluid accumulation and intrauterine fluid accumulation?

Under normal circumstances, pelvic effusion and intrauterine fluid accumulation may be caused by physiological factors, pelvic inflammatory disease, vaginitis, endometritis, or congenital abnormalities of the reproductive system. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Physiological Factors

Women may experience increased secretions in the uterine cavity during ovulation, leading to fluid accumulation after ovulation, which can result in small amounts of fluid in the pelvic and uterine cavities. This is a normal physiological phenomenon. Maintaining a positive mindset and healthy lifestyle habits can help alleviate discomfort.

2. Pelvic Inflammatory Disease (PID)

Poor personal hygiene during menstruation may lead to bacterial infections, causing pelvic inflammation and resulting in pelvic effusion. The inflammation may also cause hydrosalpinx (fluid accumulation in both fallopian tubes), with fluid refluxing into the uterine cavity, leading to intrauterine fluid accumulation. Patients are advised to follow medical instructions and take medications such as Fuyankang tablets, Gynecological Qianjin tablets, or Jingteng capsules for treatment.

3. Vaginitis

Unhygienic sexual activity may trigger bacterial infection in the vagina, leading to vaginitis. Due to inflammatory stimulation, surrounding tissues may become affected, causing ascending infection, fluid exudation, and resulting in pelvic and intrauterine effusion. Symptoms may include lower abdominal pain and increased vaginal discharge. Patients should take medications such as Ornidazole tablets, Levofloxacin tablets, or Miconazole Nitrate Vaginal Tablets under medical supervision to relieve symptoms.

4. Endometritis

After childbirth or abortion, retained placental tissue or incomplete involution at the placental attachment site may lead to endometritis, causing inflammatory secretions from endometrial cells to accumulate in the uterus, forming intrauterine fluid collection. Inflammation may also cause irregular shedding of the endometrium, leading to accumulation of inflammatory exudates and resulting in pelvic effusion. Common accompanying symptoms include lower abdominal pain, increased vaginal discharge, and backache. Patients may be prescribed medications such as Ceftriaxone Sodium for Injection, Cefoxitin Sodium for Injection, or Metronidazole Injection under a doctor’s guidance to alleviate symptoms.

5. Congenital Abnormalities of the Reproductive System

Congenital abnormalities such as imperforate hymen, transverse vaginal septum, or vaginal atresia may obstruct normal fluid drainage, leading to hematometra (blood accumulation) in the uterine cavity, which can cause pelvic and intrauterine effusion. Patients are advised to visit the hospital for evaluation and consider surgical treatments such as resection of vaginal septum, vaginoplasty, or hymenotomy.

Patients are encouraged to maintain good dietary and personal hygiene habits, drink plenty of water, exercise regularly, and maintain emotional stability, all of which contribute to recovery and overall health.
