Stretch marks are often associated with pregnancy, which is why they are more common in women, but they can appear whenever your body is going through rapid changes, such as during puberty or times of great weight loss or gain.
Stretch marks are a normal part of puberty for most girls and guys. When a person grows or gains weight really quickly (like during puberty), that person may get fine lines on the body called stretch marks. Stretch marks happen when the skin is pulled by rapid growth or stretching. Although the skin is usually fairly elastic, when it's overstretched, the normal production of collagen (the major protein that makes up the connective tissue in your skin) is disrupted. As a result, scars called stretch marks may form. If you're noticing stretch marks on your body, you're not alone. Most girls and women have them, usually on their breasts, thighs, hips, and butt. Many women get them during pregnancy. Stretch marks are more common in girls, but guys can get them, too. People who are obese often have stretch marks.
