Due to the excessive stretching of pregnant women's abdominal skin, the elastic fibers in the skin are broken, and some pink or purple wavy lines with different widths appear on the abdominal skin. After delivery, these patterns will gradually disappear, leaving white or silvery shiny scar lines, that is, stretch marks.

Why do unmarried women have similar stretch marks? According to analysis, it is related to the following reasons:

1. Glucocorticoids in human body can decompose elastic fibers in skin and denature them. At the same time, it can also inhibit the proliferation of fibroblasts and lead to the rupture of skin elastic fibers. In addition, in adolescence, due to the rapid growth of the body, the rapid growth of bones, excessive stretching of the skin, and the rupture of elastic fibers of the skin, wrinkles similar to stretch marks appear. According to foreign reports, 70% of women under the age of 20 have dry lines. Men can account for 40%; Girls who are not fat account for about 35%; Boys have 15%. Obviously, these skin patterns have nothing to do with pregnancy.

2. Because some women are too obese, subcutaneous fat accumulates on the abdominal wall, thighs, arms and breasts, which makes the skin in these parts over-inflated. Later, due to measures such as dieting and weight loss, subcutaneous fat decreased rapidly, and the originally highly expanded skin contracted, resulting in wrinkles that looked like stretch marks.

3. Some people take glucocorticoids for a long time to treat diseases, and some people suffer from certain diseases, such as diabetes, huge ovarian tumor resection, and a large number of patients with ascites subsided, and their skin also has stretch marks.

Therefore, stretch marks are not a "patent" for pregnant women, and others can have similar dermatoglyphics. As long as it is not caused by disease, there is no need to panic.
