What are the causes of hyperemesis gravidarum? How to treat vomiting with good results

Hyperemesis gravidarum occurs in the early stages of pregnancy and can usually be cured after 20 weeks of pregnancy. The differential diagnosis of hyperemesis gravidarum includes nausea and vomiting without complications, such as pregnancy, gastric ulcer, gastroenteritis, viral hepatitis, pyelonephritis, kidney stones, ovarian distortion, hyperthyroidism, diabetes ketoacidosis, migraine, etc. What is pregnancy induced vomiting? About 50% -80% of pregnant women feel nauseous, and 50% feel nauseous. Persistent vomiting is associated with pre pregnancy weight and dehydration, with pregnancy ketosis reaching up to 3%. Pregnancy related diseases are the most common cause of liver dysfunction during pregnancy, with pregnancy specificity. Severe nausea and vomiting during pregnancy may require hospitalization, with patients often experiencing dehydration and malnutrition. The cause of severe vomiting during pregnancy is not yet clear. There are many theories, ranging from psychological tendencies, including conversion disorders, to the evolution of protecting mothers and fetuses from potentially harmful foods. Some hormone levels seem to also play a role, as nausea and vomiting symptoms peak when levels of chorionic gonadotropin and estradiol are high. In addition, smokers with lower levels of estradiol also have a lower incidence of vomiting. The risk factors of hyperemesis gravidarum include past medical history, hyperthyroidism, mental illness, hydatidiform mole pregnancy, diabetes, multiple pregnancy, multiple pregnancy, body mass index increase, and daily intake of high saturated fat before pregnancy. A study also identified female fetuses as a risk factor for hyperemesis gravidarum, and Helicobacter pylori infection is also associated with hyperemesis gravidarum. 2. Pregnancy vomiting treatment includes both non drug and drug interventions, and early pregnancy vomiting treatment is superior to other treatments. Nausea or vomiting almost occurs before 9 weeks of pregnancy. When nausea or vomiting begins for the first time after 9 weeks, other situations should be considered. For patients with hyperemesis gravidarum, there are also patients who inhibit thyroid stimulating hormone levels. The treatment of hyperthyroidism should not have evidence of thyroid diseases, such as goiter, thyroid antibodies. The use of vitamins or doxorubicin alone as first-line drugs is safe and effective. Clinicians should encourage low incidence and severity of nausea and vomiting during pregnancy, and encourage women to take prenatal vitamins for one month before fertilization. Supportive treatment is recommended for thyroid examination in pregnant women with transient thyrotoxicosis, vomiting, or abnormal pregnancy. Patients who cannot tolerate oral fluids and clinical symptoms of dehydration for a long time should receive intravenous injection of hydrates. Strongly consider correcting ketosis and vitamin deficiency, including long-term vomiting of glucose and vitamins. Starting enteral catheter feeding as a first-line treatment, supporting nutrition for women with severe vomiting during pregnancy, unresponsive to medication, and unable to maintain weight. Inserting a peripheral central catheter can only serve as the ultimate measure for women with severe vomiting during pregnancy, as this intervention can lead to serious complications and may lead to pregnancy.
