How Diabetes Affects Toenails

Tuesday, 30 December 2025 00:00

Diabetes can lead to various foot and toenail issues due to poor circulation, nerve damage, and compromised immune function. Common toenail problems in diabetics include onycholysis, which is a separation of the nail from the nail bed, ingrown toenails, fungal infections, and periungual erythema, which is redness around the nail. These conditions often arise because diabetes weakens the body’s ability to fight infections and heal wounds. Symptoms include pain, swelling, discoloration, or a thickened nail, which may become brittle or discolored. Fungal infections may cause the nail to crumble or thicken, while ingrown toenails can cause tenderness and redness. Treatment may involve antifungal medications, proper nail trimming techniques, or the use of custom orthotics to alleviate pressure. In more severe cases, a podiatrist may recommend medical intervention or even nail removal. Proper foot care, including regular check-ups with a podiatrist, is essential for preventing complications. If you are dealing with these types of issues, it is suggested that you make an appointment with a podiatrist.

If left untreated, toenail fungus may spread to other toenails, skin, or even fingernails. If you suspect you have toenail fungus it is important to seek treatment right away. For more information about treatment, contact one of our doctors of Texas. Our doctors can provide the care you need to keep you pain-free and on your feet.

Symptoms

  • Warped or oddly shaped nails
  • Yellowish nails
  • Loose/separated nail
  • Buildup of bits and pieces of nail fragments under the nail
  • Brittle, broken, thickened nail

Treatment

If self-care strategies and over-the-counter medications does not help your fungus, your podiatrist may give you a prescription drug instead. Even if you find relief from your toenail fungus symptoms, you may experience a repeat infection in the future.

Prevention

In order to prevent getting toenail fungus in the future, you should always make sure to wash your feet with soap and water. After washing, it is important to dry your feet thoroughly especially in between the toes. When trimming your toenails, be sure to trim straight across instead of in a rounded shape. It is crucial not to cover up discolored nails with nail polish because that will prevent your nail from being able to “breathe”.

In some cases, surgical procedure may be needed to remove the toenail fungus. Consult with your podiatrist about the best treatment options for your case of toenail fungus.
