Diabetic blisters can appear suddenly and may look alarming. These fluid-filled blisters often develop on the feet, hands, legs, or forearms and closely resemble burn blisters—yet they usually form without pain or injury.
Although generally painless, they require careful attention. Open skin poses a higher risk of infection for people with diabetes, particularly due to reduced circulation or nerve damage. Medical guidance can help protect the area and ensure proper healing.
Skin Infections
People with diabetes are more prone to skin infections due to compromised immune defenses. These infections may present as swollen, warm, or painful areas of skin, sometimes accompanied by itching or small blisters.
Yeast infections caused by Candida are especially common, thriving in moist areas such as between toes, around nails, or on the scalp. Keeping skin clean and dry is essential, but medical treatment—often involving antifungal or antibiotic medication—may be necessary to prevent complications.
Shin Spots (Diabetic Dermopathy)
Diabetic dermopathy appears as light brown, scaly patches on the shins and is often mistaken for age spots. These marks are usually painless and may include slight indentations in the skin.
Although harmless, they reflect long-term blood vessel damage caused by elevated blood sugar. Improving glucose control can help these spots fade over time, while persistently high levels may cause them to linger.
