Nausea in late pregnancy is a sign of a violation of its normal course, and is often accompanied by vomiting and the general unfavorable state of the expectant mother.
Nausea in the morning is one of the main symptoms when suspected of gestosis (a complicated pregnancy).
Nausea on the 20th week of pregnancy can be both a manifestation of late toxicosis, and a symptom of beginning gestosis, which requires observation by a doctor. Gestosis, as a complication of pregnancy, causes considerable discomfort - and the future mother, and yet unborn baby. Clinically, it is manifested by increased blood pressure, swelling, shortness of breath, nausea, vomiting, intolerance to transport.
Nausea on the 25th week of pregnancy is a reliable sign of the onset of gestosis, as the toxicosis ends already at the 16-20th week of pregnancy, together with the completion of maturation and the beginning of the functioning of the placenta.
Nausea, exciting the second trimester of pregnancy, suggests the obstetrician-gynecologist on the need for careful monitoring of pregnancy, the appointment of drugs that facilitate the course of this condition. Nausea in the second half of pregnancy is an unfavorable factor during pregnancy and indicates both a violation in the mother's body, and possible problems in the development of the fetus. From the side of the mother in the role of problems can act: hormonal disorders, diseases of the gastrointestinal tract and other obshchematic pathology. On the part of the fetus, this symptom can be manifested as a violation of the protective function of the placenta, a violation of the hormone synthesizing function of the amnion, chorion and placenta.
In the presence of a pregnant woman's complaints of intense nausea, vomiting and general malaise in the second half of pregnancy, the expectant mother necessarily requires hospitalization and follow-up to avoid complications and termination of pregnancy.
