Who Gets Stretch Marks?
About 90% of pregnant women get stretch marks. Growth spurts and sudden or excessive weight gain cause stretch marks in young people. They affect 70% of adolescent females and about 40% of young males. Young women commonly get them on their breasts, thighs, hips, abdomen and buttocks. Young people often develop stretch marks from participating in certain body-altering sports such as weightlifting or from the use of dangerous bodybuilding steroid drugs.
