General treatment: Drinking a lot of water, it is generally recommended to drink more than 2,000 milliliters of water per day, and you can also drink more soups and other foods, such as soybean milk, chicken soup and so on. 2. Intravenous supplementation: Intravenous supplementation with saline, glucose water and balancing fluids can help promote the production of amniotic fluid and increase the amount of amniotic fluid. 3. Saline injection: If the amount of amniotic fluid is too low, saline can be injected through abdominal amniocentesis if necessary, but it is not used in most cases because it is a traumatic operation. Pregnant women with low amniotic fluid must actively cooperate with the doctor to take treatment or treatment, to avoid the impact on the fetus.
