Stretch marks
Striae; Striae atrophica; Striae distensaeStretch 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.
Considerations
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
Causes of stretch marks may include any of the following:

Home Care
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.
Weight gain
Unintentional weight gain is when you gain weight without trying to do so and you are not eating or drinking more.
When to Contact a Medical Professional
If stretch marks appear without a clear cause, such as pregnancy or rapid weight gain, call your health care provider.
What to Expect at Your Office Visit
Your provider will examine you and ask about your symptoms, including:
- Is this the first time that you have developed stretch marks?
- When did you first notice the stretch marks?
- What medicines have you taken?
- Have you used a cortisone skin cream?
- What other symptoms do you have?
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.

Striae in the popliteal fossa - illustration
Striae in the popliteal fossa. Striae or stretch marks result from stretching of the skin, or other influences such as Cushing syndrome. Most pregnant women experience striae at some point during their pregnancy. This picture shows striae in the popliteal fossa (the area on the back side of the leg at the knee joint). When the striae first appear they have a violaceous (red-purple) color, but over time they take-on a dull white appearance.
