Skin tags alone are not a sign of diabetes, but they do appear more often in people who have it
A skin tag is a small, harmless growth of skin that hangs from the body, usually on the neck, armpits, groin, or under the breasts. Millions of people have them and never develop diabetes. However, research shows that people with type 2 diabetes are more likely to have skin tags than people without diabetes. The connection is real, but skin tags by themselves do not mean you have diabetes.
The link exists because both skin tags and type 2 diabetes are associated with insulin resistance — a condition where your body does not respond well to the hormone insulin. When your body struggles to use insulin, your skin cells can grow abnormally, leading to skin tags. At the same time, your pancreas works harder to produce more insulin, which over time can lead to type 2 diabetes. So skin tags and diabetes share a common cause, rather than one causing the other.
If you have skin tags, especially if you have several of them or they appeared suddenly, it is worth mentioning to your doctor at your next visit. Your doctor can assess your overall health and may recommend screening for diabetes or prediabetes if other risk factors are present.
Key Takeaways
- Skin tags are more common in people with type 2 diabetes, but having skin tags does not mean you have diabetes.
- Both skin tags and type 2 diabetes are linked to insulin resistance, which is why they often occur together.
- Other signs of insulin resistance include dark patches of skin (acanthosis nigricans), weight gain around the midsection, and difficulty losing weight.
- If you have multiple skin tags or they appeared suddenly, mention them to your doctor as part of a broader health conversation.
- A blood test is the only way to know whether you have diabetes or prediabetes — skin tags alone cannot diagnose either condition.
Why skin tags and diabetes are connected
Insulin resistance is the bridge between skin tags and type 2 diabetes. When your body becomes resistant to insulin, several things happen at once. Your skin cells receive signals that cause them to grow and multiply abnormally, creating the small growths we call skin tags. Meanwhile, your pancreas responds by producing even more insulin to try to do the job, and over years this extra work can exhaust the pancreas and lead to type 2 diabetes.
Skin tags are not caused by diabetes itself — they are caused by the same underlying metabolic problem that can lead to diabetes. This is why skin tags are sometimes called a marker of insulin resistance rather than a symptom of diabetes. A marker is a sign that something else may be happening in your body, but it is not proof that the condition exists.
People who are overweight or obese are at higher risk for both insulin resistance and skin tags. Pregnancy can also trigger skin tags because hormones during pregnancy can increase insulin resistance. Age plays a role too — skin tags become more common as you get older, as does type 2 diabetes.
Other skin changes that go with insulin resistance
Skin tags are not the only skin change linked to insulin resistance. If you notice skin tags along with other changes, that combination is worth discussing with your doctor.
Acanthosis nigricans is a darkening or thickening of the skin, usually in the neck, armpits, or groin. It looks like a dark, velvety patch and is one of the most reliable skin signs of insulin resistance. People with acanthosis nigricans have a much higher chance of having prediabetes or type 2 diabetes than the general population.
Other skin changes that can accompany insulin resistance include frequent skin infections, slow-healing cuts or sores, and a rash or itching with no clear cause. None of these by themselves means you have diabetes, but when they appear together with skin tags, they suggest your body may be struggling with insulin.
When to talk to your doctor about skin tags
You do not need to see a doctor just because you have a skin tag. Most people have at least one at some point, and they are completely harmless. However, certain situations warrant a conversation with your doctor.
If you have multiple skin tags, especially if they appeared over a short period of time, mention them at your next checkup. If you also have a family history of diabetes, are overweight, or have noticed other changes like dark patches of skin or difficulty losing weight, tell your doctor about all of these things together. Your doctor can then decide whether screening for diabetes or prediabetes makes sense for you.
If you have already been diagnosed with prediabetes or type 2 diabetes, skin tags are not a concern in themselves, but they may be a sign that your blood sugar control needs attention. Discuss them with your doctor as part of your regular diabetes management.
How diabetes screening works
If your doctor thinks you should be screened for diabetes, the process is straightforward. A blood test called a fasting glucose test measures your blood sugar after you have not eaten for at least eight hours, usually overnight. A result below 100 mg/dL is normal, 100 to 125 mg/dL suggests prediabetes, and 126 mg/dL or higher suggests type 2 diabetes.
Your doctor may also order an A1C test, which shows your average blood sugar over the past two to three months. This test does not require fasting and gives a longer-term picture of your blood sugar control. An A1C below 5.7% is normal, 5.7% to 6.4% suggests prediabetes, and 6.5% or higher suggests type 2 diabetes.
If screening shows you have prediabetes, you have time to make changes. Weight loss, regular physical activity, and dietary changes can prevent or delay the onset of type 2 diabetes. Your doctor can refer you to a diabetes prevention program or a dietitian who can help you make a plan.
What you can do if you are concerned
If you have skin tags and are worried about diabetes, the first step is to schedule a checkup with your doctor. Bring a list of any other changes you have noticed — weight gain, fatigue, increased thirst, or difficulty losing weight — so your doctor has the full picture.
In the meantime, focus on the things that reduce your risk for both insulin resistance and type 2 diabetes. These include maintaining a healthy weight, moving your body regularly (even a 30-minute walk most days helps), eating a diet rich in vegetables and whole grains, and limiting sugary drinks and processed foods. If you have a family history of diabetes, these steps are especially important.
Remember that skin tags are extremely common and most people who have them never develop diabetes. But if you have skin tags along with other risk factors — family history, overweight, age over 45, or other metabolic changes — it is reasonable to ask your doctor about screening. Catching prediabetes early gives you the best chance to prevent type 2 diabetes from developing.
Frequently Asked Questions
Do skin tags mean I definitely have diabetes?
No. Skin tags are more common in people with diabetes, but most people with skin tags do not have diabetes. Skin tags are a possible marker of insulin resistance, which is a risk factor for diabetes, but they are not a diagnosis. Only a blood test can tell you whether you have diabetes.
Can removing skin tags prevent diabetes?
No. Removing skin tags will not prevent or treat diabetes because skin tags and diabetes share a common cause (insulin resistance) rather than one causing the other. Removing the skin tags does not address the underlying metabolic issue. If you are concerned about diabetes risk, focus on weight management, exercise, and diet.
What is the difference between skin tags and acanthosis nigricans?
Skin tags are small, soft growths that hang from the skin. Acanthosis nigricans is a darkening and thickening of the skin that looks velvety and usually appears in folds like the neck or armpits. Acanthosis nigricans is a stronger marker of insulin resistance than skin tags, and people with it have a higher risk of diabetes.
How often should I be screened for diabetes if I have skin tags?
That depends on your other risk factors. If you have skin tags but no other risk factors for diabetes, your doctor may recommend screening every three years starting at age 45. If you have skin tags plus overweight, family history, or other risk factors, your doctor may recommend more frequent screening. Ask your doctor what schedule makes sense for you.
Can I get skin tags removed if I have diabetes?
Yes. If you have diabetes and want skin tags removed for cosmetic reasons or comfort, your dermatologist can remove them. Removal does not affect your diabetes management. Talk to your doctor if you are interested in removal options.
