Stretch marks can appear when there is rapid stretching of the skin. They are often associated with the abdominal enlargement of pregnancy. They can be found in children who have become rapidly obese. They may also occur during the rapid growth of puberty in males and females. Striae are most commonly located on the breasts, hips, thighs, buttocks, abdomen, and flank.

Stretch marks appear as parallel streaks of red, thinned glossy skin that over time become whitish and scarlike in appearance. The stretch marks may be slightly depressed and have a different texture than normal skin.

Striae may also occur as a result of abnormal collagen formation, or a result of medications or chemicals that interfere with collagen formation. They may also be associated with prolonged administration of cortisone compounds, diabetes mellitus, Cushing disease, and post-pregnancy.

There is no specific care for stretch marks. Advertised creams and salves to prevent stretch marks during pregnancy are of little value. However, the marks often will disappear after the cause of the skin stretching is gone. Avoiding rapid weight gain helps in the case of stretch marks associated with obesity.

If striae or stretch marks appear without obvious cause such as pregnancy or rapid weight gain, call your health care provider.
