Excessive amniotic fluid generally does not require special treatment if it does not affect the fetus, but can be treated with medication or surgery if uncomfortable symptoms occur. About 1/3 of pregnant women with amniotic fluid overload have an unknown cause, called idiopathic amniotic fluid overload. Obvious amniotic fluid excess may be related to fetal structural abnormalities, pregnancy complications and complications, and other factors. If the patient has excessive amniotic fluid but the fetus is normal, special treatment is usually not necessary and temporary observation is sufficient. However, if the patient has excessive amniotic fluid and the fetus is abnormal, it is necessary to release an appropriate amount of amniotic fluid through amniocentesis, injecting isamoxanide and inducing labor. If the fetal lungs are not yet mature, dexamethasone needs to be given to promote the maturation of fetal lungs before considering termination of pregnancy. Specific medications need to be prescribed. The etiology of amniotic fluid is not clear, and may be related to factors such as fetal structural abnormalities, pregnancy comorbidities and complications. Pregnant women should seek prompt medical attention if they have excessive amniotic fluid, in order to identify the specific cause of the disease, and give targeted treatment under the guidance of the doctor.
