Pregnancy reaction

Introduction In the early pregnancy (about six weeks after menopause), the increase of chorionic gonadotropin (HCG) in pregnant women, decreased gastric acid secretion and prolonged gastric emptying, leading to dizziness, loss of appetite, acid or food, or disgusting greasy nausea, morning vomiting, etc. A series of reactions, collectively referred to as pregnancy reactions. These symptoms generally do not require special treatment. After 12 weeks of gestation, as the level of HCG in the body decreases, the symptoms naturally disappear and the appetite returns to normal. But to remind pregnant women that not all vomiting is an early pregnancy reaction. Because hormones and HCG work together to cause pregnancy reactions in early pregnancy, each person will have different physical changes in pregnancy response according to differences in physical fitness. Popularly speaking, it is not the same individual, and the degree of reaction is different. Symptoms in the early stages of pregnancy generally occur during the period from 6 weeks of menopause to 3 months of pregnancy.

Cause

Pregnancy reaction may be mainly related to the imbalance of hormonal mechanism and mental state in the body. The role of hormones refers to the highest level of hCG in the first trimester of pregnancy when the vomiting of pregnancy is the most serious; the concentration of hCG in the blood of patients with twin pregnancy or blister block is significantly increased, and the incidence of hyperactivity is also significantly increased. Close relationship with hCG. In addition, if the adrenal cortical function is low, the secretion of corticosteroids is insufficient, so that the water and carbohydrate metabolism in the body is disordered, gastrointestinal symptoms such as nausea and vomiting appear, and the symptoms can be significantly improved when ACTH or corticosteroid treatment is used, so the adrenal function is also considered. Lowering also has a certain relationship with pregnancy vomiting. It is believed that vitamin B6 deficiency may also be one of the causes of the disease. It can cause vomiting and worsen the history of severe dysmenorrhea.

After the diagnosis of pregnancy-induced hyperemesis, it is necessary to determine the severity according to clinical manifestations. For severe cases, the following tests are required:

First, the blood: check the blood routine and hematocrit to help understand whether there is blood concentration, if possible, the whole blood viscosity and plasma viscosity can be checked for carbon dioxide binding or blood gas analysis to understand the blood pH, alkali reserve and acid and acid balance. It is also necessary to measure serum bilirubin liver and kidney function.

Second, urine: daily calculation of urine volume, urine specific gravity, ketone body for urine three-biliary test.

Third, ECG examination: This examination is particularly important to avoid, can help to find out whether there is hypokalemia or hyperkalemia and myocardial condition.

Differential diagnosis

In the diagnosis of whether the symptoms of vomiting are normal pregnancy reactions, according to the history, clinical manifestations and related examinations to determine whether pregnancy, determine the pregnancy, according to its clinical manifestations, and through differential diagnosis to exclude hydatidiform moles and other diseases, you can confirm the diagnosis. In addition to the clinical manifestations, the above tests can be performed to identify the severity of the condition.

According to the history and clinical manifestations, it is first clear whether pregnancy, if it is definitely a pregnancy, it is also necessary to exclude vomiting caused by the digestive system or other diseases of the nervous system. However, there was a case that had been pregnant in April, but continued to be vomiting, extremely wasting and withered, accompanied by hypokalemia, and was diagnosed as pyloric obstruction caused by gastric cancer by gastrointestinal angiography and gastroscopy. Improved after surgery. Therefore, in critically ill patients who cannot be explained by hyperemesis in pregnancy, they must be carefully identified with surgical diseases.
