Bitterness in the mouth of pregnant women is related to their daily diet as well as gastrointestinal and gallbladder disorders. During pregnancy, women are likely to eat fatty foods because of the need for increased nutrition, and if they consume too much fatty foods, they are likely to develop gallbladder disease. If the gallbladder excretes bile abnormally, and if it is accompanied by a weakened gastrointestinal function, food will accumulate in the gastrointestinal tract, resulting in esophageal reflux and bitter mouth symptoms. You can first go to the hospital for an ultrasound examination of the liver and gallbladder to determine whether there is chronic inflammatory disease of the gallbladder. If it is determined that cholecystitis is accompanied by abnormal bile excretion, timely treatment with anti-inflammatory drugs is required. If it is also determined that the gastrointestinal motility is reduced. Some gastrointestinal motility enhancing drugs can be used as appropriate. However, since a woman is pregnant, many drugs should not be used casually and must be chosen carefully. It is best to choose some Chinese medicines that do not affect the fetus, such as those that strengthen the spleen and stomach, help digestion, and improve the inflammation of the gallbladder. During the treatment period, it is important to pay attention to a light diet and not to eat fatty foods and spicy foods, otherwise it is likely to aggravate the inflammation of the gallbladder area. Therefore, if you want to improve the symptoms of bitter mouth, you should first eat a light diet and not eat particularly stimulating foods.
