Striae; Striae atrophica; Striae distensae
Stretch marks are irregular areas of skin that look like bands, stripes, or lines. Stretch marks are seen when a person grows or gains weight rapidly or has certain diseases or conditions.
The medical name for stretch marks is striae.
Stretch marks can appear when there is rapid stretching of the skin. The marks appear as parallel streaks of red, thinned, glossy skin that over time become whitish and scar-like in appearance. Stretch marks may be slightly depressed and have a different texture than normal skin.
They are often seen when a woman's abdomen gets larger during pregnancy. They can be found in children who have become rapidly obese. They may also occur during the rapid growth of puberty. Stretch marks are most commonly located on the breasts, hips, thighs, buttocks, abdomen, and flank.
Causes of stretch marks may include any of the following:
There is no specific care for stretch marks. Marks often disappear after the cause of the skin stretching is gone.
Avoiding rapid weight gain helps reduce stretch marks caused by obesity.
If stretch marks appear without clear cause, such as pregnancy or rapid weight gain, call your health care provider.
Your provider will examine you and ask about your symptoms, including:
If the stretch marks are not caused by normal physical changes, tests may be done. Tretinoin cream may help reduce stretch marks. Laser treatment may also help. In very rare cases, surgery may be done.
