Why do I get skin tags on my neck and armpits if I have insulin resistance?

Skin tags—small, soft, benign growths—often appear in folds of skin such as the neck, armpits or groin. While friction and genetics play a role, one of the strongest drivers is metabolic: people with Insulin Resistance frequently develop skin tags. Here’s why, and what you can do about it.

What are skin tags?
Skin tags (acrochordons) are harmless flaps of skin attached by a thin stalk. They’re made of blood vessels and collagen surrounded by skin. Common locations include:

• Neck
• Armpits
• Eyelids
• Under the breasts
• Groin folds

Most people find them more of a cosmetic nuisance than a health threat. But when they cluster around the neck and armpits, it often signals an underlying issue—Insulin Resistance.

How Insulin Resistance leads to skin tags
Insulin Resistance means your cells respond less effectively to insulin, the hormone that helps move glucose from your blood into cells. To compensate, your pancreas pumps out more insulin. Persistently high insulin levels can drive skin changes by:

1. Stimulating growth factors

   • High insulin increases insulin-like growth factor 1 (IGF-1).
   • IGF-1 encourages skin cell (keratinocyte) and fibroblast proliferation.
   • More cell growth means a greater chance of benign overgrowths (tags).

2. Promoting acanthosis nigricans

   • Insulin Resistance often coexists with acanthosis nigricans—dark, velvety patches of skin in folds.
   • Both conditions reflect the same metabolic imbalance and growth-promoting signals.

3. Causing low-grade inflammation

   • Excess insulin can trigger inflammatory pathways in fat and skin.
   • Chronic inflammation further alters skin structure, predisposing to tags.

Why tags show up in neck and armpits
While Insulin Resistance affects the whole body, tags concentrate where:

• Skin rubs against skin (friction stimulates local growth)
• Blood flow and insulin delivery are high
• IGF-1 receptors are more abundant in the thin, delicate skin of folds

Additional risk factors
Besides Insulin Resistance, these make skin tags more likely:

• Obesity
• Family history of skin tags
• Age (over 40)
• Pregnancy (temporary hormonal spikes)
• Polycystic ovary syndrome (PCOS)

Signs that warrant further evaluation
Skin tags are usually harmless, but talk to a doctor if you notice:

• Rapid increase in number or size
• Pain, bleeding or color changes
• Other metabolic symptoms such as fatigue, increased thirst, frequent urination or unexplained weight gain
• Dark, velvety patches (acanthosis nigricans) spreading beyond typical areas

Managing skin tags by addressing Insulin Resistance
The best way to reduce new skin tags is to tackle the underlying Insulin Resistance. Strategies include:

• Dietary changes
– Focus on low-glycemic, whole foods (vegetables, lean protein, legumes).
– Limit added sugars, refined carbs and sugary drinks.
– Spread carbohydrates evenly throughout the day to avoid insulin spikes.

• Regular physical activity
– Aim for at least 150 minutes of moderate exercise per week (brisk walking, cycling).
– Include resistance training 2–3 times weekly to build muscle and improve glucose uptake.

• Weight management
– Even a 5–10% reduction in body weight can improve insulin sensitivity.
– Combine calorie control with increased activity for sustainable loss.

• Stress reduction
– Chronic stress raises cortisol, which can worsen Insulin Resistance.
– Try mindfulness, yoga or simple breathing exercises daily.

• Adequate sleep
– Strive for 7–9 hours per night.
– Poor sleep disrupts hormones that regulate appetite and insulin.

Medical treatments for skin tags
If tags are bothersome, a healthcare provider can remove them easily:

• Cryotherapy (freezing with liquid nitrogen)
• Electrocautery (burning off with electric current)
• Ligation (tying off to cut blood supply)
• Sharp excision (cutting with sterile scissors)

Removal is quick, usually painless with local anesthesia, and carries minimal risk.

Monitoring your overall health
Because skin tags can be an external clue to a deeper issue, it’s wise to keep track of your metabolic health. If you’re wondering whether your tags, fatigue or other symptoms point to Insulin Resistance or another concern, consider a free, online symptom check, using the doctor approved Ubie Symptom Checker.

When to seek medical attention
Always speak to a doctor if you experience:

• Symptoms that could be life-threatening (chest pain, severe shortness of breath, sudden weakness)
• Rapidly worsening metabolic signs (marked weight changes, persistent high blood sugar readings)
• Skin changes accompanied by systemic symptoms (fever, unexplained pain or bleeding)

Conclusion
Skin tags on the neck and armpits often reflect underlying Insulin Resistance driving excess insulin and growth-promoting signals in the skin. While the tags themselves are benign, they offer a visible clue that your metabolism may need attention. By improving diet, exercise, sleep and stress management, you can enhance insulin sensitivity and reduce the likelihood of new skin tags. If you have concerns about skin changes or metabolic symptoms, don’t hesitate to discuss them with your doctor. If it helps, start with a free, online symptom check, using the doctor approved Ubie Symptom Checker and then bring your findings to your healthcare provider. Always seek professional advice for anything serious or life-threatening.
