Skin tags are small, soft, benign growths that commonly appear on the skin. They are typically flesh-colored or slightly darker and often look like a tiny piece of skin hanging off the body by a small stalk. Skin tags are common, leading many to wonder about their development and potential disappearance, especially in relation to weight fluctuations.
Understanding Skin Tags and Their Formation
Skin tags, also known as acrochordons, are composed of collagen fibers, nerve cells, and blood vessels covered by skin. They form in areas where skin frequently rubs against itself or clothing, such as the neck, armpits, groin, eyelids, and under the breasts. This friction can lead to an overgrowth of skin cells.
Other factors contribute to skin tag development. Genetics play a role, as individuals with family members who have skin tags may have increased susceptibility. Age is another factor, with skin tags becoming more common after midlife and increasing in prevalence up to age 60. Hormonal changes, such as those experienced during pregnancy, can also contribute.
The Connection Between Weight and Skin Tags
Excess weight increases the likelihood of developing skin tags. This is largely due to increased skin-on-skin friction in areas with folds, like the neck, armpits, and groin. This irritation creates an environment for skin tag growth.
Obesity, insulin resistance, and type 2 diabetes are linked to an increased prevalence of skin tags. Elevated insulin levels, common in insulin resistance, stimulate the proliferation of skin cells, leading to skin tag formation. Skin tags can indicate underlying metabolic disturbances, highlighting the connection between skin health and systemic conditions like insulin resistance. Studies show a correlation between higher BMI and skin tags, which are also more common in individuals with diabetes.
The Impact of Weight Loss on Existing Skin Tags
Weight loss can reduce the likelihood of developing new skin tags. By reducing body weight, skin-on-skin friction decreases, minimizing irritation that contributes to new growths. Improving metabolic health through weight loss, particularly by enhancing insulin sensitivity, also lowers the risk of new skin tags.
However, weight loss is generally not effective in making existing skin tags disappear. Once formed, skin tags typically remain unless physically removed. The primary benefit of weight reduction is preventing future occurrences rather than resolving current ones.
Managing Skin Tags When Weight Loss Isn’t Enough
If existing skin tags are bothersome, professional removal options are available from a dermatologist. Common methods include cryotherapy, which freezes the skin tag with liquid nitrogen, and surgical excision, where it is cut off. Cauterization, using heat, and ligation, tying off the blood supply, are also used.
Consult a healthcare provider if a skin tag changes appearance, bleeds, becomes painful, or causes discomfort. Attempting home removal is not recommended due to risks of bleeding, infection, or incomplete removal.
