No one enjoys dealing with skin tags—they can be both annoying and uncomfortable, especially when they interfere with daily activities. They often require special care to prevent irritation or damage. Although skin tags might resemble moles, they are typically harmless and don’t indicate any serious health problems. However, certain conditions or changes in the body can cause them to appear, making it helpful to understand the potential causes.

Diabetes

People with diabetes are more susceptible to developing skin tags. This is because diabetes leads to fluctuating blood sugar levels and hormonal imbalances, which can disrupt normal skin function. The skin's ability to regenerate or maintain its structure weakens, creating an environment where skin tags can form more easily. A recent study has even revealed that individuals with diabetes who also have elevated cholesterol levels are at a higher risk of getting skin tags, making it a common condition among diabetics.

Obesity

Obesity brings with it several skin-related issues, and skin tags are no exception. Those who are overweight or obese are more likely to experience skin tags, especially in areas where the skin folds and rubs together frequently, such as the inner thighs, armpits, and stomach. The constant friction in these regions creates the ideal conditions for skin tags to develop. Additionally, the increased surface area of skin leads to more opportunities for friction to occur, further raising the chances of skin tag formation.

Friction

Friction is a significant cause of skin tags. Whether it’s tight clothing rubbing against the skin or skin rubbing against itself, this irritation often results in the formation of tags. When the skin is subjected to repetitive friction, especially in areas that experience pressure or rubbing, like the neck, underarms, or waist, skin tags are likely to form. Vigorous activities like exercise or even excessive sweating can increase this friction, accelerating the likelihood of skin tag growth in affected areas.

Pregnancy

Pregnancy triggers a wide range of hormonal changes, as well as physical transformations in the body. These changes, especially weight gain, make pregnant women more prone to developing skin tags. The skin around the belly, which stretches the most during pregnancy, is a common area where skin tags may appear. Additionally, tags can show up on the face, neck, eyelids, and underarms as the skin undergoes various changes due to pregnancy hormones. This is why skin care during pregnancy is particularly important.

Aging

As we grow older, our skin naturally begins to lose collagen, which is the protein responsible for maintaining its firmness and elasticity. Without enough collagen, the skin becomes more prone to sagging, which leads to an increased likelihood of skin tags forming. According to the National Institute of Health, around 59 percent of people will develop at least one skin tag by the time they reach 70. The combination of stretched skin and friction in older adults makes it easier for these small growths to appear.

Hyperinsulinemia

Hyperinsulinemia, a condition characterized by elevated insulin levels in the blood, often goes hand in hand with type II diabetes. However, it can also develop in individuals who do not have diabetes. Skin tags are commonly seen in those with hyperinsulinemia because insulin plays a crucial role in how the skin functions and regenerates. Blood sugar regulation directly impacts skin health, and when this balance is disrupted, it becomes easier for skin tags to form, especially in areas of friction.

Hormonal Imbalances

Hormonal imbalances, particularly in estrogen and progesterone, can lead to various skin issues, including the appearance of skin tags. These imbalances are especially common during menopause or as part of the aging process. When hormone levels fluctuate, the skin's normal balance is disrupted, making it more vulnerable to the formation of skin tags. In more severe cases, these imbalances may require the attention of an endocrinologist to restore proper hormone levels and reduce the risk of additional skin growths.

Polycystic Ovary Syndrome (PCOS)

Polycystic Ovary Syndrome, or PCOS, is a hormonal disorder that causes enlarged ovaries filled with small cysts. Women with PCOS often experience a range of symptoms, such as irregular periods, excess hair growth, and weight gain. These hormonal changes, along with high insulin levels, increase the likelihood of developing skin tags. The areas most affected are those with frequent skin friction or folds. Managing insulin levels and addressing hormonal imbalances are essential steps to preventing skin tags in women with PCOS.

Birt-Hogg-Dube Syndrome

Birt-Hogg-Dube Syndrome is a rare genetic condition that can lead to skin issues, including skin tags. Although this syndrome primarily affects children, adults with this condition may also experience skin tags on the neck, face, and upper chest. Skin tags in these areas can be a sign of the syndrome. It’s important for individuals with Birt-Hogg-Dube Syndrome to have regular medical check-ups, as the condition can also increase the risk of kidney cancer and lung diseases, making early detection key to managing health risks.

Human Papillomavirus (HPV) Infection

Human Papillomavirus, or HPV, is a common sexually transmitted infection that is known to cause warts. While skin tags are not the same as warts, recent studies suggest that HPV infections may sometimes contribute to the development of skin tags. Detecting HPV can be difficult, as the infection often presents no symptoms in its early stages. Therefore, regular STI testing is recommended to ensure early detection and treatment, as HPV can lead to complications beyond skin tags, including certain cancers.
