Women may have a small amount of pelvic effusion after pregnancy, which is a normal physiological phenomenon and does not need special treatment. However, if more pelvic effusion is detected during pregnancy, it may be pathological effusion, which may affect the health of the fetus and cause abdominal pain or lumbosacral pain and other symptoms in pregnant women. At this time, under the guidance of the doctor, appropriate treatment methods can be selected according to the amount of fluid accumulation. If only a small amount of fluid accumulation is needed, avoid eating spicy food. Regular reexamination is required. If there is a large amount of fluid accumulation, you can take some drugs that do not affect the fetus as instructed by the doctor. You should carefully check during pregnancy and not use drugs at will, So as not to affect the fetal development.
