OVERVIEW
Skin tags, also known as acrochordons, are benign growths that typically appear in areas where skin rubs against itself or clothing. While the exact cause isn't fully understood, friction and rubbing are believed to be significant factors. Other factors that may increase the likelihood of developing skin tags include genetics, health conditions like diabetes, and hormonal changes such as those during pregnancy.
Here's a more detailed look at the potential causes:
Health conditions:
Human Papillomavirus (HPV): Some studies suggest a possible link between HPV infection and skin tag development.
Diabetes: People with diabetes, particularly type 2, are more likely to develop skin tags.
Obesity: Overweight or obese individuals may be more susceptible to skin tags due to increased skin-on-skin friction.
Insulin resistance: Insulin resistance, a precursor to diabetes, has also been linked to skin tag formation.
Hormonal changes: Pregnancy and menopause can lead to hormonal fluctuations that may increase the likelihood of skin tag development.
Age: Skin tags tend to become more common with age, particularly after 40.
Friction and rubbing: Skin tags frequently develop in areas where the skin rubs together, such as the neck, armpits, groin, and under the breasts. This friction can stimulate the formation of the tags.
Genetics: A family history of skin tags suggests a genetic predisposition.
