Physiological and biological skin changes in pregnancy.

Area of Science:

• Obstetrics and Gynecology
• Dermatology
• Maternal-Fetal Medicine

Background:

• Pregnancy profoundly impacts all maternal organ systems, including the skin.
• Skin changes during pregnancy can be either normal physiological adaptations or pathological conditions known as dermatoses of pregnancy.
• Accurate identification of these skin changes is vital for obstetric and dermatologic care.

Purpose of the Study:

• To review the physiological skin changes that occur during pregnancy.
• To provide guidance for differentiating normal pregnancy-related skin alterations from pathological dermatoses.
• To emphasize the importance of this knowledge for ensuring maternal and fetal health.

Main Methods:

• This is a review article.
• It synthesizes current knowledge on pregnancy-related dermatological changes.
• The focus is on physiological alterations and their clinical significance.

Main Results:

• Physiological changes include alterations in skin pigmentation, hair growth cycles, nail structure, and connective tissue elasticity.
• Vascular and hematological changes, such as increased vascularity and altered blood counts, are common.
• Modulation of glandular function, including sweat and sebaceous glands, is also observed.

Conclusions:

• Understanding the spectrum of physiological skin changes in pregnancy is essential for dermatologists and obstetricians.
• Distinguishing normal adaptations from pathological dermatoses ensures appropriate management and promotes optimal outcomes for mother and fetus.
• This knowledge supports comprehensive care during pregnancy.
