Detailed answer

Stretch marks, also known as striae, are caused by rapid growth or stretching of the skin. They can occur in both males and females due to various reasons such as pregnancy, weight gain, weightlifting, puberty, or genetic predisposition. Anemia, on the other hand, is a condition characterized by a deficiency of red blood cells or low hemoglobin levels. While anemia can cause certain skin-related symptoms like pale skin, it does not directly cause stretch marks. It's important to note that each individual's skin is unique, and the presence of stretch marks does not indicate any specific medical condition like anemia.
