Cherry Angiomas and Diabetes: The Real Connection

Somebody told you the little red dots mean your blood sugar is off. They are the weakest signal on that whole checklist, and the signs that actually carry weight look nothing like them. Acanthosis nigricans, skin tags, foamy urine, and cherry angiomas get bundled into the same list online, as if each one meant the same thing. They do not. That is not something you got wrong. It is how the lists are written.

So this page sorts them. You get the honest ranking of every sign on that list, exactly where cherry angiomas fall on it and why, and what to do about the red dots themselves once the worry part is settled. For the broader picture on the dots, including every known cause and location, see the complete cherry angioma guide.

The insulin resistance signs people are actually looking for

Four of the five items on that search list are genuine markers, and the red dots are the weakest one. The list below ranks them by how much a clinician would actually act on each, which is the ordering nobody puts in the listicles.

Acanthosis nigricans, the one that actually means something

If you are hunting for a skin sign of insulin resistance, this is the one to look for. It shows up as darker, velvety, slightly thickened skin where the body folds, most often the back of the neck and the armpits, and people usually assume it is dirt that will not wash off. It is not. It is skin responding to high circulating insulin, and it is a common enough prediabetes tell that dermatologists treat it as a prompt to check blood sugar. The American Academy of Dermatology is the plain-language reference for what it looks like. Unlike a cherry angioma, it can fade when the underlying metabolic picture improves.

Skin tags, the runner-up

Skin tags land in the same folds and often on the same person. They are soft flaps of skin on a narrow stalk, harmless in themselves, and their association with insulin resistance is consistent enough that finding a crop of them alongside acanthosis nigricans is a reasonable prompt to get tested. They are a different lesion from a cherry angioma in every way that matters: flesh-toned rather than red, soft rather than firm, and made of skin rather than blood vessels. If that is what you are actually looking at, start with the complete skin tag guide instead.

Foamy urine, the item on the list that is not about your skin

This is the one worth acting on. Occasional foam happens to everyone, usually from a fast stream or a dehydrated morning, and it settles within a minute. Foam that keeps appearing, trip after trip, can mean protein is leaking into the urine, which is one of the early signals of kidney strain that gets watched in people with diabetes. Protein in the urine is screened for routinely in diabetes care rather than watched and waited on, and the National Institute of Diabetes and Digestive and Kidney Diseases is the plain-language reference for it. A urine test settles the question in a day, so if that symptom is on your list, it deserves the appointment far more than the red dots do.

Where cherry angiomas actually sit on that list

Cherry angiomas sit at the bottom, and age is the reason. A cherry angioma forms when a small cluster of blood vessels near the skin surface widens and then stays widened, the way a kink in a garden hose stays kinked after you let go. They start appearing for most people after 30 and by 70 nearly everyone has a few, which means any condition that also becomes more common with age will look statistically linked to them.

That said, the proposed link is not invented. Insulin-like growth factor, which runs higher in insulin-resistant states, promotes the growth of new blood vessels, and the chronic low-grade inflammation that comes with type 2 diabetes plausibly contributes to the same vascular changes. Several studies have observed more cherry angiomas in people with type 2 diabetes and metabolic syndrome than in age-matched controls. What nobody has untangled is the direction, because age drives both sides of the comparison.

Neither the American Academy of Dermatology nor NIH MedlinePlus names diabetes as a confirmed cause. Both document cherry angiomas simply as a common benign lesion. Hormonal shifts are a better-documented influence on the count than blood sugar is, and that thread is picked up in why hormones cause cherry angiomas.

What is established and what is still theoretical

Here is the honest split, because this topic gets muddled more than almost any other cherry angioma question.

↔ Swipe the table sideways to see the full comparison.

That split is the whole reason the red dots keep ending up on checklists they do not belong on. A correlation across populations is not a rule about you. Plenty of people with diabetes have almost no cherry angiomas, and plenty of people with flawless metabolic panels have dozens.

Should you worry if you have diabetes and cherry angiomas?

Not because of the cherry angiomas. On their own they are benign whether or not you have diabetes, they do not become cancerous, and their presence says nothing about how well controlled your blood sugar is. One new red dot, or several appearing over a few years, is not a reason to escalate anything.

What does deserve a conversation is a pattern, not a single spot: many new ones arriving quickly, especially alongside other changes such as darkening in the skin folds, a lesion that does not match the usual smooth red dome, one that bleeds untouched, or one with an irregular border. The combination is what earns the visit. The sudden-onset version of this question is covered in multiple cherry angiomas appearing suddenly, and if you are not certain the spot is a cherry angioma at all, the side-by-side is in cherry angiomas vs hemangioma vs petechiae. The Mayo Clinic gives useful general guidance on when any skin lesion warrants an in-person look.

Fixing the metabolic picture is worth doing for a dozen reasons. Clearing the red dots you already have is not one of them.

Removing cherry angiomas when you have diabetes

Diabetes does not change how a cherry angioma is removed. It changes where you start and how long the healing takes. The lesion is the same knot of widened vessels regardless of what nudged it into forming, so the mechanism that clears it is the same too. The full at-home walkthrough is in the best at-home cherry angioma removal guide.

How the plasma pen works

A fine plasma arc reaches the widened vessel cluster without the tip ever touching the skin. The treated dot forms a small protective scab, the scab lifts on its own between Day 3 and Day 7, and the skin underneath renews over Week 2 to Week 3. The OcuraLife pen runs 9 power settings, which is the part that matters here: a 1 mm dot on the collarbone and a 5 mm one on the shoulder are not the same job, and a single fixed power treats them as if they were. As one customer put it, it is like bringing the derm to your bathroom.

What changes if your blood sugar runs high

Healing timelines stretch. Skin that heals slowly stays open to irritation longer, so the Day 3 to Day 7 scab window can run longer than average and the sensible response is patience rather than a second pass. Circulation matters too: the lower legs, where circulation is most often compromised in long-standing diabetes, are not the place to start. The trunk, shoulders, and arms are, which is also where most cherry angiomas appear anyway. Keep the area clean while the scab is on, and keep the new skin out of the sun once it lifts.

Numbing cream, healing patches, recovery cream, and SPF 50 are available separately or together in the Ultimate Bundle. They are not included with the pen itself, and none of them are required to treat a spot. They exist because the days after the treatment are where a clean result is won or lost.

The bottom line

The checklist that brought you here mixes signals of very different weight. Acanthosis nigricans and skin tags are worth a blood test. Persistent foamy urine is worth a urine test this week. Cherry angiomas are worth neither, because they are benign, they are mostly about age, and they are not used as a diagnostic sign of anything.

Which leaves the red dots as what they always were: a cosmetic question with a straightforward answer. Treat the blood sugar for the reasons that genuinely matter to your long term health. Treat the dots separately, by removing them.
