There is no clear evidence on which foods are effective in improving pelvic fluid. Pelvic fluid is a manifestation, not just a disease. The most important thing is to identify the cause of pelvic fluid rather than treating it as a manifestation. Pelvic fluid can be categorized into physiological and pathological according to the cause. Physiologic pelvic fluid is small in amount, not accompanied by other discomforts, and is related to ovulation, small amount of menstrual blood reflux, etc. It is mostly seen in women of childbearing age, and the peritoneum also secretes a small amount of fluid to lubricate the pelvic and abdominal cavities, so it generally does not require any special treatment, and is regularly reviewed. Pathological pelvic fluid can be seen in acute and chronic pelvic inflammatory disease, ectopic pregnancy, rupture of corpus luteum, pelvic peritoneal tuberculosis or malignant tumors, etc., according to the onset of the urgency and other accompanying symptoms, combined with the examination and auxiliary examination can be identified; some diseases of other organs and systems such as cirrhosis of the liver, cardiac failure can cause venous reflux obstruction, the fluid in the blood vessels leak into the pelvic and abdominal cavities and result in pelvic effusion. There are many possible causes of pelvic fluid, and when pelvic fluid is found, one should consult a doctor in time to improve the relevant examinations for appropriate treatment.
