What is the common name for stretch marks on the skin?

Stretch marks on the skin are commonly referred to as striae. This term specifically describes the streaks or lines that can develop when the skin is stretched rapidly due to factors such as weight gain, pregnancy, or growth spurts. Striae most frequently appear on areas of the body like the abdomen, thighs, hips, and breasts. They initially present as red, purple, or dark brown streaks, depending on an individual’s skin tone, but can fade to a lighter color over time.

The other terms listed relate to different skin conditions. Bed sores refer to pressure injuries that develop in areas of skin that are under pressure, typically in immobile patients. Xanthomas are lipid (fat) deposits that occur on the skin and are generally associated with cholesterol disorders. Urticaria, also known as hives, consists of raised, itchy welts on the skin due to an allergic reaction or other causes. Understanding these distinctions highlights the specificity of the term striae in relation to skin stretching and its common occurrence.
