Doctors don't definitively know why skin tags grow, but the prevailing theories center around irritation and friction.
Possible Reasons for Skin Tag Growth
While the exact cause of skin tag development remains unclear, several factors are believed to contribute to their growth:
-
Friction and Irritation: The most common explanation points to repeated rubbing or friction between skin surfaces. This is why skin tags are often found in areas like the neck, armpits, groin, and under the breasts. As the skin rubs, it can cause the cells to grow abnormally, resulting in a skin tag.
-
Obesity: People who are obese tend to have more skin folds, increasing the likelihood of skin-on-skin friction. This heightened friction may explain why skin tags are more prevalent in individuals with obesity.
-
Underlying Medical Conditions: Some studies suggest a possible link between skin tags and conditions like diabetes and insulin resistance. However, more research is needed to confirm these associations.
-
Hormonal Changes: Fluctuations in hormones, such as those experienced during pregnancy, may also contribute to the development of skin tags.
-
Genetics: There may be a genetic predisposition to developing skin tags, meaning they can run in families.
What to Do if Your Skin Tag is Growing
If you notice a skin tag growing or changing, it's best to consult a dermatologist or other healthcare professional. While skin tags are generally harmless, they can sometimes become irritated or inflamed, or you may want to have it removed for cosmetic reasons. A doctor can properly diagnose the growth and recommend the best course of action.
