Atopic eczema can worsen during pregnancy and then produce a red, scaly rash, sometimes with itchy nodules. So-called polymorphic pregnancy rash is also relatively common, and blisters and small raised red rashes appear on the abdomen at the end of pregnancy. It itches. This goes away 1-2 weeks after birth. Itching that starts in the palms of the hands and soles of the feet in mid- or late pregnancy can be caused by a build-up of bile (intrahepatic cholestasis). Only itchy marks can be seen in the skin. Severely itchy blisters and fluid-filled blisters that occur at the end of pregnancy can be caused by gestational pemphigoid. The two last-mentioned conditions can increase the risk of disease in the fetus and must be followed up by a doctor. In addition, pregnancy can affect the skin (for example, darkening of the skin), hair and nails.
During pregnancy, hormonal changes occur that affect the immune system. This happens to prevent the mother's immune system from affecting the fetus. This means that a pregnant woman can more easily get infections and autoimmune diseases, such as lupus.
In case of rash and itching during pregnancy, you should first try a moisturizer. The use of prescription cortisone creams or allergy medicines (antihistamines) must be assessed on a case-by-case basis by the patient's doctor.
