Does pregnancy urticaria affect the fetus?

Urticaria is a localized edema of the skin and mucosa due to temporary increase in vascular permeability. Most patients cannot find the exact cause. It can be caused by food, infection, drugs, respiratory tract inhalants or skin contacts, physical factors, mental and endocrine factors, systemic diseases, etc. The impact of urticaria on the fetus varies from person to person. If the pregnant woman belongs to acute urticaria, and the condition of urticaria is serious, accompanied by symptoms of anaphylactic shock such as palpitation, irritability and decreased blood pressure, it may cause fetal distress, and in severe cases, it may show fetal abortion or stillbirth, especially in the first trimester of pregnancy. If pregnant women show gastrointestinal tract mucosal involvement, nausea, vomiting, abdominal pain, diarrhea and other manifestations, or show laryngeal bronchial edema, dyspnea asphyxia, can also cause fetal dysplasia, intrauterine distress and other symptoms. If urticaria is caused by infection, such as virus, bacterial infection, showing urticaria at the same time will show high fever, chills and other systemic poisoning symptoms, fetal development is also affected. If pregnant women only scattered on the skin show different sizes of wheals, and will soon subside, the impact on the fetus is limited. once pregnant women show urticaria, it is recommended to go to a regular hospital for treatment under the guidance of a doctor.
