Causes of pregnancy response

The pregnancy response is a physiological phenomenon and generally does not require special treatment. The etiology of hyperemesis gravidarum is unknown so far, and may be mainly related to the hormonal mechanism of the body and the imbalance of mental state. The effect of hormone refers to the highest hCG level in the early pregnancy when the vomiting of the pregnancy is the most severe; the hCG concentration in the blood of patients with twin pregnancy or vesicular placenta is significantly increased, and the number of hyperemesis is also significantly increased, all suggesting the disease Closely related to hCG. In addition, if the adrenocortical function is low, its secretion of corticosteroids is insufficient, which causes water and sugar metabolism disorders in the body, and nausea and vomiting, and other gastrointestinal symptoms. When ACTH or corticosteroids are used, the symptoms can be significantly improved. Decrease is also related to pregnancy hyperemesis. Some people think that vitamin B6 deficiency may also be one of the reasons for the onset of vomiting. Those who have a history of severe dysmenorrhea will have an increase in hyperemesis gravidarum.

A few pregnant women have a particularly severe reaction with persistent vomiting, or even inability to eat or drink water. In addition to vomiting food, there is mucus foam, and there may also be bile or bloody substances. Due to frequent vomiting, pregnant women are dehydrated. If the condition continues to worsen, severe symptoms such as convulsions, coma, jaundice, and even death will occur. Once the illness occurs, you need to go to the hospital in time.

Clinical manifestations of pregnancy response

Dizziness, fatigue, loss of appetite, sour food or aversion to greasy, nausea, morning sickness, etc.

Pregnancy response test

A positive pregnancy test can be diagnosed with associated symptoms. For patients with hyperemesis gravidarum, blood biochemical examination and urine ketone levels can provide clinical basis.

Diagnosis of pregnancy response

According to the medical history, clinical manifestations and laboratory tests, it is first to determine whether pregnancy. If it is confirmed that pregnancy, vomiting caused by other diseases of the digestive system or nervous system must also be ruled out. Such as: meningitis, brain tumors or uremia cause vomiting.

Hyperemesis gravidarum also needs to be differentially diagnosed with important diseases such as thyroid disease, gastrointestinal disease, and mental and psychological problems.

Pregnancy response therapy

Mild nausea and vomiting are common symptoms in early pregnancy. A small diet and frequent meals can often be relieved by taking vitamin B6.

Patients with hyperemesis gravidarum should be hospitalized and fasted for 2 to 3 days. According to the test results, the amount of water loss and electrolyte disorders should be clarified, and calories, water and electrolytes should be supplemented as appropriate. Most pregnant women with hyperemesis gravidarum improve after treatment and can continue to conceive. If conventional treatment is ineffective, persistent jaundice, persistent proteinuria, elevated body temperature, sustained above 38 ° C, tachycardia (120 beats per minute), and associated Wernicke syndrome are life-threatening pregnant women, and pregnancy termination should be considered.

Currently, the United States Drug and Food Administration (FDA) has approved several drugs for the treatment of pregnancy reactions and hyperemesis gravidarum, including metoclopramide and chlorpromazine. The use of these drugs during pregnancy has not resulted in the birth of a newborn Increased risk of defects.

Lifestyle adjustments may also reduce pregnancy reactions: eat less often, but avoid fasting; eat light foods and try not to eat foods that are too salty, greasy, or have a special smell; foods such as biscuits, bread, and soda crackers can reduce morning sickness Discomfort; add water to avoid dehydration; keep indoor air fresh, often open windows to ventilate, and go to places with less smell; eat or not eat cold, non-digestible food; reduce the amount of exercise and workload, ensure adequate rest, etc.

Impact of pregnancy response on the fetus

In general, in the early stages of pregnancy, because the embryo is small and grows slowly, there is not much nutrition required. A mild pregnancy reaction has little effect on the pregnant woman and the fetus. However, the severe pregnancy reaction lasts longer. Will adversely affect the health of pregnant women and the growth and development of the fetus. Because as the fetus grows up, more and more nutrients are needed, and the severe pregnancy reaction will prevent pregnant women from insufficient nutrition. The mother can only use the proteins and fats stored in her body to supplement the fetus's needs. Weight loss, weight loss, and decreased resistance. Particularly severe reactions may also threaten the lives of pregnant women and fetuses due to dehydration or acidosis.
