A large amount of fluid in the pelvis usually excludes physiological factors, because the amount of pelvic fluid under physiological conditions is small and can be gradually absorbed. This symptom is often related to pathological factors, such as pelvic inflammatory disease, ectopic pregnancy rupture and bleeding, ovarian cysts, pelvic and abdominal cavity tumors. At this time, you should go to the hospital for systematic examination to clarify the cause and then treat it symptomatically. Common causes and treatments 1. Pelvic inflammatory disease: Inflammatory infection in the pelvis leads to congestion and edema in the fallopian tubes and ovaries, as well as increased secretions, resulting in effusion in the pelvis. At this time, the diagnosis can be confirmed by the results of posterior vault aspiration, ultrasound and laparoscopy. Oral antibiotics, such as cefoxitin and cefuroxime, can be administered under the guidance of professional doctors. If the effusion is not serious, Chinese herbal medicine can be chosen to regulate it, such as heat-clearing and detoxifying agents, and if it is serious, puncture and extraction is needed. Patients need to pay attention to personal hygiene, wash the vulva with flowing warm water in the morning and evening, and change the intimate clothing regularly. 2. ruptured bleeding of ectopic pregnancy: after the appearance of ectopic pregnancy, blood flows into the pelvic cavity thus forming pelvic effusion. At this time, you should go to the hospital and choose medication or surgery according to the development of embryo to avoid the rupture of the pregnancy sac, commonly used drugs such as mifepristone and methotrexate. Patients are advised to rest and not to exert themselves too much. 3. ovarian cysts: rupture and bleeding of ovarian cysts can also lead to a large amount of fluid in the pelvis, which should be treated immediately and, if necessary, surgically. 4. abdominopelvic tumors: due to increased vascular permeability, fluid filtration increases, resulting in pelvic fluid, which is usually treated by surgical excision, radiotherapy and other means. Attention Patients should maintain an optimistic attitude in the treatment process, relieve tension and anxiety, and have confidence in the treatment. Pay attention to increasing nutrition, avoiding spicy and fried foods, exercising properly, improving body resistance, combining work and rest, and avoiding excessive fatigue.
