What your Nails tell you about Diabetes


When discussing diabetes, the focus is often on blood sugar management, cardiovascular health, and the potential complications affecting major organs. However, the impact of diabetes on nail health is a lesser-known aspect that deserves attention. You need to know how diabetes impacts nail health, including common nail-related issues, potential causes, and practical tips for maintaining healthy nails while managing diabetes.

Nail Changes Associated with Diabetes:

  • Yellowing: Individuals with diabetes may notice changes in the color of their nails, ranging from yellowish discoloration to a darker shade. This is due to the breakdown of sugar and its effect on the collagen in nails.
  • Brittleness: People with diabetes may also experience brittle nails. This is because high blood sugar levels can damage the keratin in the nails, which makes them more likely to break.
  • Thickening: Nails may also thicken in people with diabetes. This is because high blood sugar levels can increase the production of keratin in the nails.
  • Ingrown toenails: Diabetes can cause changes in skin health and increase the risk of developing foot-related complications. Ingrown nails, where the nail grows into the surrounding skin, can be more common in individuals with diabetes.
  • Nail fungus: People with diabetes are also more likely to develop nail fungus. This is because high blood sugar levels can create a warm, moist environment that is ideal for the growth of fungus. Fungal infections can cause thickening, crumbling, and discolored nails.

Potential Causes of Nail Issues in Diabetes:

  • Poor Blood Circulation: Diabetes can impair blood flow to the extremities, including the fingers and toes. Insufficient blood circulation can affect the delivery of nutrients and oxygen to the nails, leading to nail abnormalities.
  • Neuropathy: Nerve damage (neuropathy) associated with diabetes can affect the sensation in the hands and feet. Diminished sensation may make it challenging to notice early signs of nail infections or ingrown nails, leading to further complications.
  • Weakened Immune System: Diabetes can weaken the immune system’s response to infections, making individuals more susceptible to fungal infections, which can affect the nails.

Tips for Maintaining Healthy Nails with Diabetes:

  • Regular Nail Care: Practice good nail hygiene by keeping your nails clean and trimmed. Cut nails straight across and file any sharp edges to minimize the risk of ingrown nails.
  • Moisturize: Keep your nails and surrounding skin moisturized to prevent dryness and brittleness. Use a gentle moisturizer or cuticle oil to nourish the nails and promote healthy growth.
  • Protect Your Nails: Wear protective gloves while performing tasks that may expose your nails to harsh chemicals, water, or trauma. This helps prevent damage and reduces the risk of fungal infections.
  • Foot Care: Pay attention to your feet, as foot complications are common in diabetes. Inspect your nails regularly for any signs of infection, such as discoloration, thickening, or crumbling. Seek professional foot care if needed.
  • Balanced Diet: Follow a well-balanced diet that supports overall health, including nail health. Ensure your diet includes essential nutrients like biotin, vitamin E, and minerals such as iron and zinc, which are beneficial for nail strength and growth.
  • Blood Sugar Management: Consistently monitor and manage your blood sugar levels through appropriate diet, exercise, and medication. Stable blood sugar levels promote overall health, which includes nail health.
  • Seek Professional Help: If you notice persistent nail abnormalities or suspect a fungal infection, consult a healthcare professional, such as a dermatologist or podiatrist, for proper diagnosis and treatment.

While the impact of diabetes on nail health may not be widely known, it is essential to prioritize nail care as part of overall diabetes management. By practicing good nail hygiene, protecting your nails, maintaining balanced blood sugar levels, and seeking professional help when needed, you can support the health of your nails. Remember, healthy nails are not just aesthetically pleasing, but also an indication of your overall well-being.
