Skin Tags Could Be Early Warning Sign of Insulin Resistance and Diabetes Risk
Often dismissed as harmless cosmetic nuisances, those small fleshy skin tags on your neck or underarms might actually serve as a crucial early indicator of a hidden health issue. Medical professionals now emphasize that individuals who develop numerous skin tags are significantly more likely to have insulin resistance, a frequently overlooked condition that can progress to type 2 diabetes.
Doctors Often Miss the Connection Between Skin Tags and Metabolic Health
Experts warn that many physicians fail to link skin tags with underlying metabolic problems, leading patients to believe they are merely a superficial concern. While skin tags are extremely common and typically benign, forming due to consistent skin friction, their appearance in clusters—particularly around the neck, armpits, or groin—can signal that the body is struggling to process sugar effectively.
This occurs when cells become resistant to insulin, the hormone regulating blood sugar. In response, the body overproduces insulin, creating a hormonal imbalance that stimulates the growth of skin tags. Insulin resistance can remain undetected for years, with standard blood tests showing normal sugar levels even as internal damage accumulates silently.
Long-Term Health Risks and the Importance of Early Detection
Over time, untreated insulin resistance elevates the risk of developing type 2 diabetes, heart disease, and fatty liver disease. Doctors stress that a single skin tag is not concerning, but a sudden proliferation, especially alongside other risk factors like weight gain or a family history of diabetes, warrants medical evaluation.
A simple blood test from a family physician can assess insulin resistance early, when interventions are most effective. The American Academy of Dermatology Association acknowledges that skin tags are associated with diabetes and metabolic syndrome, yet this connection is frequently overlooked in clinical practice.
Real-Life Case: Janet Peets' Journey to Diagnosis and Recovery
Janet Peets, a 44-year-old California resident with a neuroscience background, spent years being told by multiple doctors that her skin tags were simply a result of aging. They first appeared during a pregnancy 15 years ago, vanished, and then returned in 2022. Each physician assured her the growths were purely cosmetic, with none suggesting a link to metabolic health.
Beyond skin tags, Peets experienced at least 12 signs of metabolic dysfunction, including unexplained weight gain of 35 pounds in nine months, severe post-meal exhaustion, persistent brain fog, constant carbohydrate cravings, medication-resistant high blood pressure, and elevated liver enzymes. After years of personal research, she asked her doctor about insulin resistance, leading to a confirmed diagnosis in 2025, along with non-alcoholic fatty liver disease.
'When I learned this, it was one of those moments where everything seemed to make sense,' Peets said. 'I'd been walking around with a visible sign of what was happening metabolically, and nobody had ever mentioned it.'
Effective Lifestyle Changes and Medical Insights
Following her diagnosis, Peets adopted a strict regimen to reverse her condition, including consuming 100 grams of protein daily with under 50 grams of carbohydrates, regular resistance training, post-meal walks, 10,000 daily steps, and specific supplements. Within ten weeks, she lost 18 pounds, eliminated cravings, boosted energy levels, and resolved plantar fasciitis.
Her story is not isolated. Medical research confirms a direct biological link between multiple skin tags and metabolic dysfunction, with high insulin levels triggering the overgrowth of skin and connective tissue cells. Skin tags related to insulin resistance often appear in areas like the neck, armpits, and groin, where cells are more hormonally sensitive.
Why Skin Tags Are a Valuable Early Warning System
Insulin resistance can persist for over a decade without detection on standard fasting glucose tests, as the pancreas compensates to maintain normal sugar levels. By the time glucose rises, prediabetes or type 2 diabetes may already be established, making skin tags a critical early alert. A patient with multiple skin tags and normal glucose could still have severe insulin resistance, nearing a serious diagnosis.
Experts recommend that patients presenting with multiple skin tags, especially if accompanied by fatigue, abdominal fat, high blood pressure, or unexplained weight changes, undergo a fasting insulin test and comprehensive metabolic panel, including liver enzymes.
'I know so many women who feel helpless and are trying to figure out how to get their health and sanity back – I was one of them,' Peets added. 'Even if your doctor keeps telling you that you're fine, listen to your body. You don't have to accept a slow decline as inevitable, and you deserve to be equipped with information to start moving the needle in the right direction.'
