Pregnancy Induced Skin Diseases

Due to hormonal changes during pregnancy, the skin around the nipple and genital becomes dark and a dark line develop in the middle of the abdomen (called LINEA NIGRA).
There may be purplish to pink streaks of stretch marks as the abdomen enlarges when the baby grows in the womb because of the stretching of the skin. These are called STRIAE GRAVIDARUM.

Some women also develop pigmentation on the face (MELASMA These are all physiological skin changes that occur during pregnancy.
The physiological skin changes tend to remain for sometime after delivery; but they usually fade, often not completely, with time.

Pigmentation can be lightened with bleaching cream; but the stretch marks usually lighten in color but rarely disappear. Creams advertised to prevent stretch marks generally do not work. Most skin diseases during pregnancy are harmless to the baby. However, Rubella (German measles), Syphilis and Genital Herpes Simplex Infection can be harmful to the baby in the womb.

What skin diseases are specifically seen during pregnancy The following skin diseases occur only during pregnancy and they usually clear after delivery:

Polymorphous Eruption of Pregnancy

One in 300 pregnant women develop this itchy skin disease. The rash usually starts on the stretch marks on the abdomen which spread to affect the rest of the body. The skin disease is not harmful to the baby in the womb and always disappears 6 weeks after delivery. Rarely, it starts after delivery of the baby but would clear after 6 weeks.

Herpes Gestationis

This skin disorder appears as tiny blisters which usually start on the umbilicus. It is very rare. Except for occasional premature birth, there is no serious risk to the baby in the womb. It tends to recur during subsequent pregnancies.

Hairfall during and after pregnancy

Significant hairfall can occur shortly after delivery. This condition is called Telogen Effluvium. Complete recovery will take place 3 to 6 months after delivery without any treatment.
