What causes stretch marks?
Stretch marks are a result of skin stretching and an increase of cortisone in your system. Cortisone is a hormone naturally produced by your adrenal glands. However, having too much of this hormone can make your skin lose its elasticity. Stretch marks are common in certain circumstances: Many women experience stretch marks during pregnancy as the skin stretches in numerous ways to make room for the developing baby. This continual tugging and stretching can cause stretch marks.
Stretch marks sometimes appear when you rapidly gain or lose weight. Teenagers may also notice stretch marks after a sudden growth spurt.
Corticosteroid creams, lotions, and pills can cause stretch marks by decreasing the skin’s ability to stretch.
Cushing’s syndrome, Marfan’s syndrome, Ehlers-Danlos syndrome, and other adrenal gland disorders can cause stretch marks by increasing the amount of cortisone in your body.
