Pelvic fluid of 16mm may be caused by physiological fluid, such as follicular fluid or intestinal lubricating fluid, which does not cause any symptoms or other reactions and does not require special treatment. However, if pelvic effusion is accompanied by recurrent lower abdominal pain, it may be caused by chronic pelvic inflammatory exudation, which needs to be treated in a timely manner, usually by taking oral Chinese medicine, such as gynecomastia net capsule or vajra capsule, etc. At the same time, it can be combined with physiotherapy, which can accelerate local blood circulation and promote the absorption of effusion and inflammation, which can be cured in most cases. The patient with pelvic effusion must pay attention to a light diet during treatment, avoiding spicy and irritating foods, and strictly prohibiting sexual intercourse and tub bathing during treatment.
