This article contains information from modern sources on the topic of early toxicosis, which most often occurs in the trimester, and in some cases can continue until the third trimester of pregnancy. On the occurrence of literature data, it can be said that diseases such as early toxicosis, the appearance of vomiting and nausea in pregnant women, the threat of diseases in pregnant women, neurological disorders, fetal asphyxia, rupture of the esophagus and retinal hemorrhage in the mother, as well as other complications. The pathogenesis of early toxicosis has many theories, for example, the theory of the influence of chorionic gonadotropin or the mechanical theory of the development of vomiting during pregnancy, but none of them can fully explain all cases of the disease. In this case, we can conclude that early toxicosis is multifactorial.Clinically, vomiting of pregnant women can occur in mild, moderate and severe severity, and in the latter case, the so-called vicious circle is often formed, which includes severe electrolyte disorders, neurological disorders, and alkalosis. Treatment of a mild form of vomiting of pregnant women is carried out on an outpatient basis, and moderate and severe – in a hospital. Conclusion. Based on the sources, the treatment of early toxicosis is based on an integrated approach. Undoubtedly, the basis for each degree will be diet, replenishment of water and electrolyte balance, as well as symptomatic treatment. Data are given on the use of both homeopathic remedies and drug therapy, as well as psychotherapeutic assistance to pregnant women.
