Striae Atrophicans

What are Striae Atrophicans?

Striae atrophicans, commonly known as stretch marks (striae), are long, narrow streaks that develop when the skin stretches rapidly. They occur due to tearing of the skin’s supporting fibers (collagen and elastin) in the deeper layer of the skin. Stretch marks are very common and are not harmful or contagious.

In the early stage, stretch marks are usually red, pink, purple, or brown (striae rubrae). Over time, they gradually fade and become white or silvery (striae albae).

Common Causes

Stretch marks may develop due to:

* Pregnancy
* Rapid weight gain or weight loss
* Growth spurts during puberty
* Bodybuilding or rapid muscle growth
* Long-term use of corticosteroid medications
* Hormonal disorders such as Cushing syndrome
* Genetic predisposition

Symptoms

* Long, thin lines or streaks on the skin
* Red, pink, purple, brown, or white discoloration
* Slightly depressed or wrinkled appearance
* Mild itching during the early stage
* Soft, smooth texture as they mature

Commonly Affected Areas

* Abdomen
* Thighs
* Hips
* Buttocks
* Breasts
* Upper arms
* Lower back
* Shoulders

Who is at Risk?

* Pregnant women
* Teenagers during puberty
* People with rapid weight changes
* Bodybuilders
* Individuals using long-term steroid medications
* People with a family history of stretch marks

Diagnosis

Diagnosis is usually based on a physical examination by a dermatologist. Additional tests may be recommended if an underlying hormonal disorder is suspected.

Prevention

* Maintain a healthy and stable body weight.
* Follow a balanced diet rich in vitamins and proteins.
* Keep the skin well moisturized.
* Avoid unnecessary long-term use of steroid medications unless prescribed.
* Stay physically active and maintain healthy skin care habits.

When to See a Dermatologist

Consult a dermatologist if stretch marks appear suddenly without an obvious cause, are widespread, associated with other symptoms such as weight changes or hormonal problems, or if you would like to discuss cosmetic treatment options to improve their appearance.
