Stretch marks (striae) are stripe-like skin marks that develop as a result of rapid weight gain or loss, when the skin is stretched, and as a result of some diseases.
Striae gravidarum, stretch marks in pregnancy, occur in about 90% of all pregnant women. They are primarily due to the rapid rate at which the skin is being stretched, combined with the influence of hormones.
Pruritic urticarial papules and plaques of pregnancy (PUPPP) is the most common skin condition of pregnancy. Typically, women affected by PUPPP develop red, itchy bumps on the belly near stretch marks (striae) during their third trimester. PUPPP usually gets better within a few weeks after delivery, does not affect the health of your baby, and has no long-term consequences for you.
Acanthosis nigricans is a skin disorder in which the skin becomes abnormally darkened and thickened. The skin is often described as "velvety" because it remains soft despite thickening. These skin changes are most often found in body creases, such as the armpits and the back of the neck.Acanthosis nigricans is commonly seen in obese individuals and in those with some endocrine problems, such as diabetes. It is also associated with polycystic ovarian disease in women, though acanthosis nigricans can occasionally be found in people who have more serious underlying health problems or who are taking certain medications. Treatment of the underlying medical condition, including weight loss, usually resolves the skin lesions.
Lichen planus (LP) is a disease of the skin and, less often, the scalp, fingernails, toenails, and/or inside the mouth or genitalia (mucous membranes). Lichen planus can resolve on its own without treatment or be chronic, even with aggressive treatment. The cause of the inflammation that leads to lichen planus is unknown.
Psoriasis is a noncontagious, lifelong skin condition that affects about 2–3% of the population of the United States. People with psoriasis have thickened, red, and often scaly patches on their skin. Psoriasis is very likely to run in families, but it can also be triggered by certain situations, such as emotional stress, injury to the skin, infection, as well as taking certain medications. The exact cause of psoriasis is unknown, but it seems to be caused by errors in how the immune system functions.
When you become pregnant, body changes are guaranteed. Your physique, moods, and energy levels will alter as your baby develops. Pregnant women also may encounter changes on their skin. A dark line extending vertically down the abdomen (linea nigra) is one example. Another common example is striae, also known as stretch marks.
Of all the common skin conditions caused by pregnancy, pruritic urticarial papules and plaques of pregnancy, or PUPPP, is probably the one that women find the most frustrating. Similar to linea nigra and striae (stretch marks), PUPPP is benign and harmless to the mother and unborn child. However, this fact doesn't lessen the discomfort and often annoying effects on the skin caused by PUPPP.
A balanced diet is crucial for overall health. But do certain foods also have specific benefits for managing psoriasis? Many people with the disease believe so. However, research has yielded mixed results. Here’s what’s known about diet and psoriasis—and what’s not.
