What is a Diabetes Rash?

A diabetes rash refers to a skin condition that occurs as a result of the underlying metabolic changes and complications associated with diabetes. It manifests as various types of skin abnormalities, ranging from mild irritation to more severe and persistent rashes.

The development of a diabetes rash can be attributed to multiple factors. Fluctuations in blood sugar levels, impaired circulation, compromised immune function, and nerve damage are some of the key contributors. These factors can disrupt the normal functioning of the skin, leading to a variety of dermatological issues.

What Does a Diabetes Rash Look Like?

A diabetes rash can have various appearances depending on the specific type and severity of the condition. Here are some common characteristics of different diabetes-related skin rashes:

Acanthosis nigricans: 

This rash appears as darkened, thickened patches of skin that may have a velvety texture. The affected areas can be brown, grey, or black, and they are often found in body folds such as the neck, armpits, groyne, and sometimes the hands or feet.

Eruptive xanthomatosis: 

This rash consists of small, yellowish bumps with a red halo around them. These bumps may be itchy and can resemble pimples or papules. They commonly appear on the buttocks, arms, legs, and backs of the hands.

Diabetic dermopathy: 

This condition presents as light brown, scaly patches on the skin, usually on the shins. The patches may be oval-shaped and slightly depressed, resembling age spots or dry patches.


Yeast infections in individuals with diabetes can cause a red, itchy rash with a distinct border. It often appears in areas prone to moisture, such as the armpits, groyne, and under the breasts. The affected skin may be swollen, have small red bumps, and feel sore or tender.

Necrobiosis lipoidica diabeticorum: 

This rash appears as raised, yellowish-brown patches on the skin, typically on the lower legs. The patches may have a shiny or waxy appearance and can develop a red border. In some cases, they can break open and form ulcers.

How to prevent diabetes rash?

Preventing diabetes rash involves maintaining good overall diabetes management and adopting healthy skin care practices. Here are some key preventive measures:

Keep blood sugar levels under control: 

Maintaining stable blood sugar levels through proper diabetes management, including medication, diet, and exercise, can help reduce the risk of developing skin rashes.

Practise good hygiene: 

Regularly cleanse your skin with mild soap and warm water. Pay extra attention to areas prone to moisture, such as folds of the skin, and keep them clean and dry.

Moisturise your skin: 

Use a gentle, fragrance-free moisturiser to keep your skin hydrated and prevent dryness. Avoid applying moisturiser between your toes to prevent fungal growth.

Avoid hot showers and baths: 

Excessive heat can strip your skin of moisture, leading to dryness and irritation. Opt for lukewarm water instead.

Wear breathable fabrics: 

Choose clothing made of breathable materials, such as cotton, to allow air circulation and reduce skin irritation.

Prevent diabetes rashes by controlling blood sugar levels, practising good hygiene, and moisturising the skin. Wear breathable fabrics, protect your skin from the sun, and avoid scratching. Regularly monitor your skin and seek medical advice for proper management and care.
