12 WARNING SIGNS THAT APPEAR ON YOUR SKIN

Diabetes can affect many parts of your body, including your skin. When diabetes affects the skin, it’s often a sign that your blood sugar (glucose) levels are too high. This could mean that:

  • You have undiagnosed diabetes, or pre-diabetes
  • Your treatment for diabetes needs to be adjusted

If you notice any of the following warning signs on your skin, it’s time to talk with your doctor.

1. Yellow, reddish, or brown patches on your skin

You may also notice:

  • The surrounding skin has a shiny porcelain-like appearance
  • You can see blood vessels
  • The skin is itchy and painful
  • The skin disease goes through cycles where it is active, inactive, and then active again.

The medical name for this condition is necrobiosis lipodica.

2. Darker area of skin that feels like velvet

dark patch (or band) of velvety skin on the back of your neck, armpit, groin, or elsewhere could mean that you have too much insulin in your blood. This is often a sign of prediabetes. The medical name for this skin condition is acanthosis nigricans.

3. Hard, thickening skin

When this develops on the fingers, toes, or both, the medical name for this condition is digital sclerosis.

On the hands, you’ll notice tight, waxy skin on the backs of your hands. The fingers can become stiff and difficult to move. If diabetes has been poorly controlled for years, it can feel like you have pebbles in your fingertips.

Hard, thick, and swollen-looking skin can spread, appearing on the forearms and upper arms. It can also develop on the upper back, shoulders, and neck. Sometimes, the thickening skin spreads to the face, shoulders, and chest.

In rare cases, the skin over the knees, ankles, or elbows also thickens, making it difficult to straighten your leg, point your foot, or bend your arm. Wherever it appears, the thickened skin often has the texture of an orange peel.

This skin problem usually develops in people who have complications due to diabetes or diabetes that is difficult to treat.

4. Blisters

It’s rare, but people with diabetes can see blisters suddenly appear on their skin. You may see a large blister, a group of blisters, or both. The blisters tend to form on the hands, feet, legs, or forearms and look like the blisters that appear after a serious burn. Unlike the blisters that develop after a burn, these blisters are not painful.

5. Skin infections

People who have diabetes tend to get skin infections. If you have a skin infection, you’ll notice one or more of the following:

  • Hot, swollen skin that is painful
  • An itchy rash and sometimes tiny blisters, dry scaly skin, or a white discharge that looks like cottage cheese

A skin infection can occur on any area of your body, including between your toes, around one or more of your nails, and on your scalp.

6. Open sores and wounds

Having high blood sugar (glucose) for a long time can lead to poor circulation and nerve damage. You may have developed these if you’ve had uncontrolled (or poorly controlled) diabetes for a long time.

Poor circulation and nerve damage can make it hard for your body to heal wounds. This is especially true on the feet. These open wounds are called diabetic ulcers.

7. Shin spots

This skin condition causes spots (and sometimes lines) that create a barely noticeable depression in the skin. It’s common in people who have diabetes. The medical name is diabetic dermopathy. It usually forms on the shins. In rare cases, you’ll see it on the arms, thighs, trunk, or other areas of the body.

8. Outbreak of small, reddish-yellow bumps

When these bumps appear, they often look like pimples. Unlike pimples, they soon develop a yellowish color. You’ll usually find these bumps on the buttocks, thighs, crooks of the elbows, or backs of the knees. They can form anywhere though.

9. Red or skin-colored raised bumps

Whether this skin condition is associated with diabetes is controversial. We know that most people who have granuloma annulare do not have diabetes. Several studies, however, have found this skin condition in patients who have diabetes. One such study found that people with diabetes were most likely to have granuloma annulare over large areas of skin and that the bumps came and went. Another study concluded that people who have granuloma annulare that comes and goes should be tested for diabetes.

10. Extremely, dry itchy skin

If you have diabetes, you’re more likely to have dry skin. High blood sugar (glucose) can cause this. If you have a skin infection or poor circulation, these could also contribute to dry, itchy skin.

11. Yellowish scaly patches on and around your eyelids

These develop when you have high fat levels in your blood. It can also be a sign that your diabetes is poorly controlled. The medical name for this condition is xanthelasma.

12. Skin tags

Many people have skin tags—skin growths that hang from a stalk. While harmless, having numerous skin tags may be a sign that you have too much insulin in your blood or type 2 diabetes.
