Expecting A Baby? Expect Some Changes In Your Skin, Hair, And Nails.

2001 SEP 6 --(NewsRx Network) -- During pregnancy, changes in the skin, hair, and nails are common. The correct diagnosis and treatment of these conditions during pregnancy are essential to ensure the health of both mother and baby.

"The body experiences profound adjustments during pregnancy, which make pregnant women susceptible to changes of the skin, hair, and nails," stated dermatologist George Kroumpouzos, MD, PhD, coauthor of "Dermatoses of Pregnancy" published in the July2001 issue of the Journal of the American Academy of Dermatology. "A careful history and thorough physical examination by a dermatologist can relieve anxiety about the nature of these skin conditions and the possible fetal or maternal risks associated with them."

Hyperpigmentation is common during pregnancy, affecting more than 90% of pregnant women. Hyperpigmentation is a skin disorder in which dark spots appear on the skin. This benign condition is attributed to an overproduction of melanin, a natural substance that gives color to the hair, skin, and iris. Normally hyperpigmented areas, such as the breasts and nipples, genital skin, and inner thighs, may become darker in pregnancy. Freckles, nevi, and scars may appear darker as well. This condition disappears in the months following pregnancy.

Melasma or chloasma, known as the "mask of pregnancy," has been reported in up to 70% of pregnant women. This common condition causes an increase of pigmentation that occurs almost exclusively in sun-exposed areas.

"Melasma presents in three facial patterns. The centro-facial pattern involves the cheeks, forehead, upper lip, nose, and chin," said Kroumpouzos, instructor in the department of dermatology, Harvard University, Boston, Massachusetts. "The malar pattern involves the cheeks and nose, and the mandibular pattern involves the side of the cheeks and jawline."

Melasma can also develop on the forearms. Dermatologists encourage the use of proper sunscreen to prevent this condition as well as treatment with topical corticosteroids, bleaching agents, chemical peels, or tretinoin. Most cases of melasma resolve after pregnancy.

"Pregnancy affects every area of the skin, including hair and nails. Undesirable changes may occur that leave pregnant women feeling anxious," said Kroumpouzos. "A discussion with a dermatologist can put a woman at ease regarding these changes."
