When our skin stretches or shrinks rapidly, few marks are developed that are called stretch marks. Sudden changes cause collagen and elastin, which support our skin, to crack. When the skin is healed, stretch marks may appear.

Not everyone develops these narrow bands on their skin. Fluctuating hormone levels seem to play a role. You have a high chance of getting stretch marks if people in your family get stretch marks.

These lines are mainly visible during or after pregnancy or after a sudden change in your weight. They also happen to adolescents who are fastly growing. Stretch marks aren’t harmful, and they often fade over time.

You may have stretch marks anywhere but these are most common on your abdomen, breasts, upper arms, thighs and buttocks.
Stretch marks usually appear as a band of parallel lines on your skin. These lines have a special color and texture than your normal skin and they turn from purple to bright pink to light gray. After touching the stretch marks with your fingers, you may feel a small ridge or indentation on your skin. Sometimes, stretch marks feel itchy or painful.

Common Reasons:

Rapidly gaining weight (this affects both men and women) :

When the body expands faster because of weight gain, skin must stretch to complete the body’s growth. When skin stretches too far, it tears. The tearing of the dermis—or the center layer of your skin—results in what we commonly see as stretch marks.
Understandably, the skin is stretched too much because weight gain can cause stretch marks.

However, weight loss also causes stretch marks. When losing weight, the skin should be relaxed and not stretched. However, rapid weight loss often ends up in excess skin, and excess skin can subdue other skin areas and cause it to stretch and tear.
Often stretch marks develop during weight gain but are not visible until the load is reduced. In this case, the weight gain creates stretch marks, but the stretch marks made visible by the weight loss are visible on the body.

During pregnancy:
The stretch marks in the supporting layers of tissues under your skin are literally tiny tears as you tighten with limitations during pregnancy.Whether you get plenty of combinations to try with their genetics: chances are, if your mom keeps them, you can, of course, but if she travels with smooth skin intact during her pregnancy, you’ll probably imitate. Rapid pregnancy weight gain also can cause you to be more at risk of getting stretch marks. And darker-skinned women are less likely to possess stretch marks than those that are fair-skinned (plus they are not as visible on dark skin). Applying light therapy can help to deal with such skin conditions.

During Puberty:
Stretch marks are a common part of puberty
in many girls and boys. When a person gains weight really fast (during adolescence) then that person can get fine lines on the body that are called stretch marks.

If you see stretch marks on your body, you are not alone. Most ladies and girls have them, usually on their breasts, thighs, hips, and butt. Many women get these marks in their pregnancy time. Stretch marks are mostly common in girls but boys can get them too.

Marfan syndrome:
The signs and symptoms that people with Marfan syndrome experience vary. Some patients may have partial types of syndrome and they may suffer from mild symptoms while others with full syndrome may be affected more severely.

Although skin scratches are not necessary to diagnose morphine syndrome, it is often present in patients. Skin features appear as lines or stretch marks that develop with significant weight change or pregnancy. They tend to look at sites like shoulder, buttocks, buttocks, and lower back trembling. It can happen at any age. These stretch marks do not appear to be a health problem and do not require any treatment.

Breast implantation:
Many candidates for breast augmentation may also be concerned that the difficulty of continuing the procedure may cause stretch marks. Excessive stretch marks are formed when the skin tissue is overly stretched, resulting in reddish, white, or purple ribbon spots, which appear in the affected area. Rapid weight loss / gain-like changes cause the skin’s inner layer (dermis) to tear when the skin is under extra pressure and produce visible underlying connective tissue in the thin top layer of skin.

Whether a patient develops stretch marks after breast augmentation depends on a variety of individual factors. The most common of these components are the patient’s risk of developing stretch marks, the scale of the implants used in the procedure (larger implants make the skin more stretched) and the techniques used in the growth procedure.

Stretch marks, however, are most ordinarily seen in situations where the skin is stretched, then relaxes. Some examples are pregnancy followed by parturition, or gaining many weights followed by weight loss. Fortunately, with breast augmentation, we are only getting in one direction, up, but not backtrack.

Over use of topical or systemic glucocorticoid drugs:

Corticosteroid creams, lotions and pills can create stretch marks by reducing the skin’s ability to stretch. Stretch marks are indented lines that always appear on the abdomen, breasts, buttocks, and thighs. Over time they decrease significantly. Extensive signs are more common in pregnant women, especially during the last trimester. Treatment may fade the stretch marks but it will not remove them completely. Stretch marks have pain or harm, but some people feel pain with the way they make their skin look.

By maintaining weight, one can reduce the risk of getting a stretch number. During pregnancy, you will gain weight in a relatively short time. Work with your doctor to avoid excessive gains by eating well and exercising. Not only does it reduce stretch marks, but it is also healthy for you and your baby.
