What causes diabetic blisters?

Diabetes is a chronic disease that affects your body’s ability to regulate blood sugar levels. It can cause a range of symptoms, from fatigue and irritability to vision problems and kidney damage. One symptom that’s less well-known but still common among people with diabetes is diabetic blisters. If you’ve ever wondered what causes these painful little bumps, read on for the full scoop.

The Basics: What Are Diabetic Blisters?

Before we dive into the nitty-gritty details, let’s make sure we’re all on the same page when it comes to what diabetic blisters actually are. Basically, they’re small fluid-filled sacs that develop on or around the feet (although they can sometimes appear elsewhere on the body as well). They tend to be quite tender and can burst if irritated or pressed too hard.

Symptoms Of Diabetic Blisters

How do you know if you have diabetic blisters? Here are a few telltale signs:

  • Small red or white bumps
  • Fluid-filled sacs
  • Tenderness or pain in affected area(s)
  • Burning sensation in affected area(s)

If you experience any of these symptoms – especially if you also have diabetes – it’s important to see a doctor right away.

So…What Does Cause Them?

Now for the million-dollar question: why do diabetic blisters happen in the first place? As with many things related to diabetes, there isn’t one simple answer. However, here are a few factors that may play a role:

High Blood Sugar

We all know by now how important it is to keep our blood sugar levels stable when we have diabetes. There are plenty of reasons for this aside from just avoiding hyperglycemia; one such reason is that high blood sugar makes us more susceptible to infections and skin issues like dermatitis rash which might leads serious problem such as blister formation. In other words, if your blood sugar is bouncing all over the place, it might make you more likely to develop diabetic blisters.

Poor Blood Circulation

Another common complication of diabetes is poor circulation. When our blood isn’t flowing well, it can cause a range of issues – including making us more prone to developing blisters on our feet due to rubbing and friction when walking or wearing shoes or footwear which doesn’t provide enough comfort.


Diabetic neuropathy, another frequent problem for those with diabetes or high blood glucose levels, refers to nerve damage that commonly affects the extremities like hands and feet.Some symptoms include numbness/tinling in affected area(s), burning sensation etc.. If this condition impacts the nerves in your feet (which is quite common), it can lead to issues with coordination and balance that make you more likely to experience foot injuries – including ones that lead to blisters.

Can You Prevent Diabetic Blisters?

As always when we talk about managing diabetes complications,Hat tip: Always seek advice from medical professional who’s been treating diabetic patients; prevention is key. While there’s no guaranteed way to never develop diabetic blisters ever again, there are a few things you can do that may help lower your risk:
