Detailed answer

Stretch marks, medically known as striae, can develop on the stomach. They are most commonly seen during pregnancy, when the skin stretches rapidly. However, stretch marks can also occur due to rapid weight gain or growth during adolescence. The stretching of the skin causes the collagen and elastin fibers to tear, resulting in the appearance of reddish or purplish streaks on the stomach. Over time, these marks may fade and become a lighter color. While stretch marks cannot be completely prevented or removed, various treatments and skincare products can help reduce their appearance and improve the texture of the skin.
