Skin Complications with Diabetes: Prevention, Management, and Treatment

People with diabetes are more likely to experience skin problems due to high blood sugar, poor circulation, and a weakened immune system. Early detection and management of these conditions can prevent severe complications. This article explores three common skin issues in diabetes: Necrobiosis Lipoidica, Diabetic Dermopathy, and Fungal Infections, including Candida.

Necrobiosis Lipoidica (NL): A Rare but Disfiguring Skin Condition

What is Necrobiosis Lipoidica?

Necrobiosis Lipoidica (NL) is a rare skin condition affecting about 1 in 300 people with diabetes. It often appears as yellow, waxy patches with a red or purple border, primarily on the shins. The skin becomes thin and translucent, exposing blood vessels and underlying tissues.

Who is at Risk?

  • Women are three times more likely to develop NL than men.
  • More common in people with long-standing diabetes and those with poor blood sugar control.

Prevention and Treatment

  • Blood Sugar Management: Maintaining near-normal blood glucose levels is crucial in preventing and managing NL.
  • Treatment Options: While treatments have limited success, options include topical steroids, phototherapy, and, in severe cases, biologic therapies.

Diabetic Dermopathy: The Most Common Skin Issue in Diabetes

What Does Diabetic Dermopathy Look Like?

Diabetic Dermopathy presents as small, round, slightly indented brown or purplish skin patches. It is most common on the shins and is linked to slow healing, often appearing in areas of prior injury or trauma.

How to Improve Diabetic Dermopathy?

  • Blood Sugar Control: Keeping blood glucose within a healthy range can help lesions fade over time.
  • Zinc Supplementation: Low doses of chelated zinc (15-25 mg daily) for several weeks may aid skin healing, especially when combined with good diabetes management.

Fungal Infections: Candida and Beyond

Why Are People with Diabetes at Higher Risk?

High blood sugar creates an ideal environment for fungi and bacteria to thrive, leading to common infections like athlete’s foot (Tinea Pedis) and Candida infections.

Common Types of Fungal Infections in Diabetes

  • Candida Infections: Can affect the mouth (thrush), nails (onychomycosis), and moist skin areas like under the breasts, in armpits, and the groin.
  • Tinea Pedis (Athlete’s Foot): Scales and cracks between the toes are often caused by Trichophyton species.

Treatment Options for Fungal Infections

  1. Topical Antifungal Creams: Prescription options like Loprox®.

  2. Oral Antifungal Medications: Including:

    • Sporanox (itraconazole): 200 mg daily for 12 weeks.
    • Lamasil (terbinafine): 250 mg daily for 12 weeks.
    • Diflucan (fluconazole): 100 mg daily.

    Caution: These medications can have serious side effects, including liver toxicity. Consult a healthcare provider before use.

  3. Natural Remedies: Over-the-counter options like tea tree oil, manuka cream, and vinegar soaks may help mild infections.

Prevention Tips for Healthy Skin with Diabetes

  • Maintain Blood Sugar Control: This is the most effective way to prevent skin complications.
  • Keep Skin Clean and Dry: Especially in skin folds and between the toes.
  • Use Antifungal Powders: Such as Tinactin in shoes and socks.
  • Avoid Damp Environments: Wear moisture-wicking socks and breathable shoes.
  • Regular Skin Checks: Monitor for any changes or signs of infection.

Managing Skin Health with Diabetes

While skin complications in diabetes can be challenging, proactive care and good blood sugar management can significantly reduce the risk. If you notice persistent skin changes, consult a healthcare professional for early treatment and management.
