Skin pattern

Introduction As the volume of bones and muscles or fat increases too fast, beyond the prolonged speed of the skin, the elastic fibers of the dermis are pulled apart to form such a pattern. The formation of Stretch marks is mainly caused by hormones during pregnancy. The swelling of the abdomen causes the elastic fibers and collagen fibers of the skin to be damaged or broken by different external forces. The skin becomes thinner and thinner, and the skin of the abdominal wall appears. Some pink or fuchsia wavy patterns of different widths and lengths. After delivery, these patterns will gradually disappear, leaving a white or silvery shiny scar line, which is Stretch marks. Some women are too obese, causing a large amount of subcutaneous fat to accumulate in the skin under the action of mechanical action. After the diet, such as weight loss, the subcutaneous fat suddenly decreases, causing the skin that has been highly dilated to shrink, resulting in It looks like stripes like stretch marks. However, if you are taking long-term glucocorticoids or certain diseases, such as diabetes, adrenal hyperfunction, etc., skin-like patterns may occur.

Cause

First, the adrenal cortex of the human body can secrete a glucocorticoid, which can break down the elastic fiber protein in the skin into sugars, which can denature the elastic fibers. At the same time, it can also inhibit the proliferation of fibroblasts, resulting in skin elasticity. The fiber breaks. In addition, rapid growth and growth, accelerated bone growth, will also promote excessive skin stretching, leading to the breakdown of the skin's elastic fibers, resulting in a similar stretch pattern of stretch marks.

Second, some women are too obese, resulting in a large accumulation of subcutaneous fat in the abdominal wall and thighs and buttocks, causing the skin of these parts to stretch excessively under mechanical action, and then subcutaneous fat is suddenly reduced due to dieting and other reasons. , causing the skin that has been highly expanded to shrink, causing stripes like stretch marks.

Third, long-term use of glucocorticosteroids or affected by certain diseases, such as diabetes, adrenal hyperfunction, etc., may have skin patterns like stretch marks.

Whether it is men, women and children, it is possible to have obesity lines. People who are obese or lose weight because of weight loss may develop obesity in obesity.

There are also several irregular stripes on the shoulders, neck, arms, abdomen, buttocks, thighs, etc.

The human abdomen has many layers from the outside to the inside. They are the skin, the elastic fibers of the skin, the subcutaneous fat layer, the rectus abdominis muscle muscle group and the tendon, the preperitoneal fat layer and the peritoneum. Under normal circumstances, the skin elastic fiber and the rectus abdominis maintain a certain elastic force, and freely expand and contract within a certain limit. When a woman is pregnant for more than 3 months, the enlarged uterus protrudes into the pelvic cavity, develops into the abdominal cavity, and the abdomen begins to swell. Due to the enlarged uterus, the skin elastic fibers and the abdominal muscles begin to elongate. Especially after 6 months of pregnancy, it is more obvious. When the limit is exceeded, the skin elastic fibers are broken, and the rectus abdominis tendon is also separated to varying degrees. As a result, irregular longitudinal cracks of pink or magenta appear on the skin of the abdomen. After the birth, although the broken elastic fiber is gradually repaired, it is difficult to return to the previous state, and the crack on the original skin gradually fades, and finally becomes silvery white, that is, stretch marks.

Differential diagnosis

Obesity: It starts to be red, gradually darkens over time, and finally turns into white stripes. If you don't get fat any longer, you can become a narrow white stripe. If some drugs that increase skin elasticity and promote collagen growth during weight gain or during pregnancy may reduce or avoid growth lines to a certain extent, there is currently no good way to reinforce them. This situation has no effect on health, so there is no need for treatment.

Stretch marks: The formation of stretch marks is mainly caused by hormones during pregnancy. The bulging of the abdomen causes the skin's elastic fibers and collagen fibers to be damaged or broken due to external forces. The skin becomes thinner and thinner, and the skin on the abdominal wall will appear. A wavy pattern of pink or fuchsia with different widths and lengths. After childbirth, these patterns will gradually disappear, leaving a white or silver-white shiny scar line, that is, stretch marks.
