What Causes Stretch marks?
Stretch marks may appear similar in different people, but they’re all caused due to various underlying factors.
The most common causes of stretch marks or striae include:
This is one of the leading causes of stretch marks in women due to the rapid growth of the baby. According to statistics, 50% to 90% of pregnant women experience stretch marks during or after pregnancy.
Rapid Weight Gain or Weight Loss
The skin expands or contracts slowly to accommodate slow increase or decreases in weight. When rapid gain or loss of weight occurs, the skin is forced to stretch or contract faster than it usually does, causing the dermis to tear.
Corticosteroid lotions, creams, and pills weaken the skin’s ability to stretch, which leads to stretch marks.
During puberty, the body produces increased amounts of growth hormones, which may lead to a rapid weight gain causing the skin to stretch suddenly.
Stretch marks can also result from certain diseases, including Cushing’s syndrome, Ehlers-Danlos syndrome, Marfan’s syndrome, and other adrenal gland conditions. These adrenal gland disorders cause an increase in the amount of cortisone in the body, which results in the formation of stretch marks.
