The arrival of the next generation is the most awaited part of the establishment of a new family, and pregnancy undoubtedly brings hope and joy to the family. However, pregnancy vomiting brings pain and anxiety to the pregnant mother. The biggest concern is that the lack of nutrition caused by the inability to eat during early pregnancy and the frequent vomiting will not affect the development of the baby and how to deal with it in order to minimize the loss and protect the baby’s intelligence and health, which is probably the concern of most families. It is worth mentioning that the clinical attitude of pregnant women towards pregnancy vomiting is often divided into three main categories: one is difficult to tolerate the distress and distress, many seek help or even terminate the pregnancy; another is to refuse any treatment for fear of drugs affecting the fetus, resulting in adverse consequences of the progress of the disease; the third is optimism and positive response, a reasonable diet and with the necessary treatment to achieve a good end. Of course, the most ideal than the third kind of people, to achieve the ideal state, it is necessary to have certain health care knowledge. First, learn what pregnancy vomiting is. Most pregnant women begin to experience loss of appetite, nausea and vomiting on the 40th day of pregnancy, the cause of which is not well understood and occurs in about 70-85% of pregnant mothers. 50% of pregnant women may experience nausea and vomiting at the same time, 25% of pregnant women only have nausea and the other 25% may not have any symptoms. This is considered by some scholars to be a normal defense reaction of the fetus. During the 20-60 days of pregnancy, the embryo is in its prime stage of cell differentiation and organ formation, during which exposure to harmful substances can cause abnormal development of the embryo and even deformities, miscarriage and fetal death. Pregnant women are also particularly sensitive during this period, with a very acute sense of smell, and the smell and taste of certain foods can cause nausea. Some researchers have also found that at this time, the food stays in the stomach of pregnant women for a longer period of time, once there is a trace of harmful substances, then “a vomit as soon as possible”, in order to protect the embryo healthy growth, not to occur abnormalities. Therefore, the morning sickness of pregnant women is actually a detoxification, a positive reaction to avoid harmful substances. Mothers are worried that due to the pregnancy reaction to eat less, pregnant women lose weight and lose body mass, will not starve the baby? The answer is no. This is because the embryo needs very few nutrients during the 3 months, plus the mother’s good health before pregnancy is sufficient to store enough nutrients to meet the nutrition of the embryo during early pregnancy. However, if pregnancy vomiting is accompanied by rapid weight loss, especially when the decline exceeds 15% of body weight, accompanied by dehydration, electrolyte disorders and metabolic acidosis, and even liver and kidney function damage, it will develop into severe pregnancy vomiting, and should be promptly referred to the hospital. In order to prevent the development of vomiting during pregnancy, pregnancy vomiting caused by the damage to the pregnant woman and the fetus, appropriate intervention is still necessary, from the following aspects: for mild vomiting, can be given a certain amount of psychological guidance, to relieve the mind concerns. The current study concluded that there is a relationship between severe vomiting in pregnancy and psychological disorders, so it is very important to maintain a good and optimistic state of mind. Special emphasis is placed on the role of family members in this regard, and positive and healthy psychological cues are an important factor in helping pregnant women get through the first step. In addition, more researched auxiliary treatment methods abroad include acupressure on the internal acupuncture point, ginger juice, massage, music therapy, etc., all of which can be used as a good way to reduce symptoms. 2, reasonable dietary nutrition: early pregnancy meals should be light and palatable, eat less and more meals, ensure enough carbohydrate-rich food to prevent constipation. Take a moderate amount of multivitamins can also effectively relieve the symptoms. Some pregnant women like to eat sour food is a certain scientific reason, can improve the symptoms of gastrointestinal discomfort after pregnancy, reduce nausea, vomiting, can also increase appetite, increase nutrition. However, pregnant women should also eat sour food should be scientific. Such as artificial pickles, vinegar products, some nutrients are basically destroyed, and some pickled foods are prone to produce carcinogens such as nitrites, which is not good for the health of the mother and fetus. It is best to choose more tomatoes, prunes, pomegranates, cherries, grapes, oranges, apples and other fresh vegetables and fruits, not only delicious, but also nutritious. 3, moderate exercise, such as outdoor walking, breathing more fresh air in the suburbs, suitable health exercises for pregnant women, can improve the mood, strengthen the body and reduce early pregnancy reaction. Finally, a small summary: pregnancy vomiting is a normal physiological phenomenon, and it is impossible to count on drugs to cure it. Adjustment of the mentality, balanced diet with the appropriate complementary therapies can alleviate, but the symptoms are serious enough to reach severe pregnancy vomiting should promptly go to the hospital for medical treatment. It is important to emphasize that the severity of personal complaints and symptoms are not proportional, but directly related to the tolerance of the individual, and can be understood by going to the hospital for the corresponding indicators and laboratory tests.
