Stretch marks are not caused by any illness. Nevertheless, they may result from severe weightlifting, pregnancy, growth spurts in adolescence, abrupt weight gain in obesity, adverse drug reactions, or a quick rise in muscle mass. When your skin stretches or shrinks rapidly, a scar forms on it. Your stretch marks become more noticeable when the skin heals because of the alteration that produces the collagen and elastin that aid in the skin’s repair.
Stretch marks are a common skin concern, but they’re not a sign of illness. They appear as a result of rapid changes in the skin’s elasticity. Stretch marks, although not caused by any disease, often result from factors like pregnancy, sudden weight gain, growth spurts, or certain medications. When the skin undergoes rapid stretching or shrinking, collagen and elastin fibers can rupture, leading to the formation of stretch marks.
