Why are there stretch marks on the legs

Stretch marks, also known as obesity marks, are a relatively common skin pattern. They are especially likely to develop in pregnant women. This is mainly due to the orange peel phenomenon caused by the enlarged belly during pregnancy. If the legs are too fat, stretch marks may also appear. These are all normal physiological phenomena, but they will affect the beauty, so they can be removed through certain methods.

Why do stretch marks appear on the legs?

These are stretch marks. Some women are too fat, which causes a large amount of subcutaneous fat to accumulate in the skin, causing it to overstretch under mechanical action. Later, due to dieting and other reasons, the subcutaneous fat suddenly decreases, causing the already highly expanded skin to shrink, thus causing stripes that resemble stretch marks. However, similar skin patterns may occur if glucocorticoids are taken for a long time or if you are affected by certain diseases, such as diabetes or hyperadrenocortical disorder. It is caused by the rupture of elastic fibers in the dermis. The reasons for the breakage of elastic fibers are: 1. Rapid development during puberty, the production of elastic fibers is lower than the development speed of the body, and the elastic fibers are torn; 2. Excessive obesity, the elastic fibers are torn; 3. Certain endocrine diseases, excessive secretion of glucocorticoids, the decomposition and breakage of elastic fibers (glucocorticoids can promote the decomposition of protein fibers); 4. Oral use of certain glucocorticoid drugs, the decomposition and breakage of elastic fibers; 5. Long-term use of topical hormone drugs, the decomposition and breakage of elastic fibers; 6. Various other factors leading to the breakage and decomposition of elastic fibers. It occurs on the inner thighs, waist and abdomen, and appears as watermelon-like cord-like skin lines with alternating red and light white colors. There are usually multiple lines, and it is neither painful nor itchy. This disease is easy to diagnose based on the onset of adolescence, site of onset, and clinical manifestations.

What are the classifications of stretch marks?

Stretch marks are a type of stretch marks, also known as expansion marks, and the medical name is "skin expansion marks". It is a common phenomenon for pregnant women to develop stretch marks. Stretch marks usually appear on the abdomen of pregnant women. Some pregnant women also develop stretch marks on their hips, thighs, buttocks and breasts. During pregnancy, stretch marks appear in the middle and late stages of pregnancy. They are "active" stretch marks. At this time, because the abdomen expands rapidly and the skin is damaged, the skin appears red and purple and wavy. Postpartum stretch marks appear as white or silvery white, shiny scar lines, also called "static" stretch marks.

1. Stretch marks during pregnancy At this time, stretch marks are mostly light red or purple, and the shape of fine lines may change. The most likely site for stretch marks to appear is the abdominal wall, but other sites such as the lower back, inner thighs, and buttocks may also develop stretch marks. This is most obvious in first-time pregnant women. 2. Stretch marks after delivery will gradually fade into white or silvery white shiny scars, and the texture will no longer change. In fact, the growth of stretch marks varies from person to person. Depending on the physical condition of the pregnant woman, the time when stretch marks begin to grow will also be different. But generally speaking, pregnant women will start to see stretch marks when they are 5 to 6 months pregnant, usually appearing on the thighs and belly.
