Skin Changes in Pregnancy

Pregnancy causes changes in skin, including spider angiomata (estrogen-related), hair growth, stretch marks (striae gravidarum), hyperpigmentation, and melasma. Rashes and acne are also common.

Maternal Insulin Resistance

During pregnancy, hormones like human placental lactogen (hPL) and elevated cortisol lead to reduced maternal responsiveness to insulin.

Gestational Diabetes Risk Factors

Family history, personal history of metabolic syndrome, and obesity increase the risk of gestational diabetes. Some ethnicities have higher prevalence.

Fetal Macrosomia

Excessive fetal growth, particularly in the shoulders and abdomen, frequently observed in pregnancies complicated by maternal diabetes.

Immune System Changes in Pregnancy

Pregnancy alters the immune system to accommodate the fetus (an allograft), modulating away from cytotoxic T-cell activity and decreasing NK cells.
