I don’t think many people like scars, after all, scars mean injury and are unsightly, especially in children, and some scars even follow the baby for life. What is scar tissue? Why does scar tissue form? When the normal tissues of human body, especially skin tissues, are traumatized, a special kind of cells (fibroblasts) will divide and proliferate and grow in the direction of the trauma to repair the cracks and defects of the trauma, the tissue formed by these cells repairing the wounds is what we call scar tissue, also called fibrous scar tissue. What are the characteristics of scar tissue? The resulting scar tissue is usually white or off-white, tough, hard, and contracted at the junction of scar and normal tissue, and is less elastic than normal tissue. What are the advantages of scar tissue? We all hate scar tissue, but in fact it is a credit to us. Scar tissue has the ability to repair cracks and defects of wounds and is a barrier to prevent infection of incisions, without scar tissue, skin wounds cannot heal. What are the bad effects of scar tissue? Obviously, most scars are disliked because they affect the appearance, especially on the face where they are abrupt, unattractive, and in some cases, can be described as difficult to look at. Scar tissue is not only this big disadvantage, but also the following three sins: a. Scar contraction affects organ function: Scar tissue is tough, hard and not very elastic, plus scar contraction may lead to organ deformation and dysfunction. Scars near joints and important organs often cause joint spasm, restricted activity and movement disorders, just like a flexible machine rusting, such as in scars occurring in the digestive tract, urinary tract If the scars occur in the digestive tract, urinary tract and other official cavity-like organs, they are likely to cause lumen narrowing, such as intestinal obstruction and urethral stricture. Second, scar adhesions: scar tissue occurs between organs and organs, or between organs and body cavity walls, forming scar adhesions, such as in the abdominal cavity, scar tissue can compress the intestinal canal leading to sticky intestinal obstruction. Third, scar hyperplasia: Some people with scars have scar hyperplasia just like crabs or centipedes. These scars not only affect the aesthetics, but also may lead to repeated infections, itching and pain, and foreign body sensation, making people very uncomfortable.
