Hair and nail changes in pregnancy

Hair and nail changes in pregnancy

Why pregnancy can change hair and nails Hair and nails are both keratinized tissues, so they respond to the shifting endocrine and metabolic environment of pregnancy. Rising estrogen tends to prolong the anagen, or active growth, phase of hair follicles. In practical terms, fewer hairs are pushed into the resting telogen phase at any one […]

Stretch marks and skin itching in pregnancy

Stretch marks and skin itching in pregnancy

What stretch marks in pregnancy are Stretch marks, also called striae gravidarum, are linear marks that commonly appear as the abdomen enlarges, although they may also develop on the breasts, hips, buttocks, and thighs. They are not a sign that anything is “wrong” with the pregnancy. Instead, they reflect the skin’s response to rapid expansion, […]

Melasma and darkening of skin during pregnancy

Melasma and darkening of skin during pregnancy

What melasma is and why pregnancy can trigger it Melasma is a common form of acquired hyperpigmentation, usually seen as symmetric brown or gray-brown patches on the cheeks, forehead, upper lip, nose, or chin. It is not an infection, and it is not dangerous in itself. The condition is multifactorial: pregnancy-related hormonal shifts, ultraviolet exposure, […]

Skin changes in pregnancy including acne and pigmentation

Skin changes in pregnancy including acne and pigmentation

Why the skin changes in pregnancy The skin is highly responsive to pregnancy physiology. Rising estrogen, progesterone, human placental lactogen, and other endocrine signals alter sebaceous gland activity, melanocyte stimulation, blood vessel tone, connective tissue remodeling, and immune responses. These effects overlap with mechanical stretching as the uterus, breasts, abdomen, and hips enlarge. In medically […]

Braxton Hicks contractions and abdominal tightening

Braxton Hicks contractions and abdominal tightening

What are Braxton Hicks contractions? Braxton Hicks contractions are intermittent, usually irregular contractions of the uterine muscle. They are sometimes called “practice contractions,” although the term can be misleading: the uterus is not rehearsing in a conscious way, but the myometrium, the smooth muscle layer of the uterus, can contract sporadically throughout pregnancy. Some people […]

Changes in libido and sexual desire during pregnancy

Changes in libido and sexual desire during pregnancy

Why libido can change in pregnancy Sexual desire is not controlled by one hormone or one emotion. It reflects a complex interaction between endocrine changes, vascular and pelvic tissue changes, nervous system arousal, fatigue, nausea, pain, sleep, self-image, relationship safety, cultural expectations, and previous sexual experiences. Pregnancy affects nearly all of these domains. Rising estrogen […]

Frequent urination and bladder changes in pregnancy

Frequent urination and bladder changes in pregnancy

Why urination becomes more frequent in pregnancy Frequent urination in pregnancy is not simply a matter of drinking more water. Several physiologic mechanisms act together. Early in pregnancy, hormonal changes influence the kidneys, blood vessels, and smooth muscle of the urinary tract. Human chorionic gonadotropin, progesterone, estrogen, and other mediators are part of the broader […]

Breast tenderness nipple sensitivity and early breast changes

Breast tenderness nipple sensitivity and early breast changes

Why breasts change so early in pregnancy Breast tissue is hormonally responsive throughout reproductive life. In early pregnancy, estrogen promotes ductal growth and vascularity, while progesterone supports lobuloalveolar development, the milk-producing glandular architecture. Human chorionic gonadotropin helps maintain the corpus luteum, which supports early progesterone production. The result can be a noticeable shift in breast […]
