Thick Toenails: Causes, Treatments, and How to Care for Them

Thick toenails, medically termed onychauxis, are a common foot condition affecting millions worldwide. Whether caused by fungal infections, aging, or underlying health issues, thickened toenails can lead to discomfort, pain, and even embarrassment. In this guide, we’ll explore what causes thick toenails, how to diagnose them, and the best treatments to restore healthy nails. We’ll also share expert tips on caring for thick toenails and preventing recurrence, including specialized solutions like the Supplend nail care pen.

  • What Are Thick Toenails?

    Thick toenails occur when the nail plate becomes abnormally dense, discolored (often yellow), and challenging to trim. This condition, known as onychauxis, can result from fungal infections (onychomycosis), injury, aging, or chronic diseases like psoriasis and diabetes. Left untreated, thick toenails may lift from the nail bed, cause pain in shoes, or even lead to infections.

What Causes Thick Toenails?

Understanding the root cause is critical for effective treatment. Here are the primary reasons for thickened toenails:

1. Fungal Infections (Onychomycosis)

Fungal infections are the leading cause of thick toenails. Fungi thrive in warm, moist environments (e.g., sweaty shoes), leading to yellow thick toenails that crumble. Athletes and older adults are particularly susceptible.

2. Aging

As we age, nail growth slows, and toenails naturally thicken. Cutting thick toenails in elderly individuals can be challenging due to reduced flexibility.

3. Trauma or Injury

Stubbing toes, repetitive pressure (common in runners), or ill-fitting shoes can damage the nail matrix, causing thickened nails as they heal.

4. Psoriasis

Psoriasis thick toenails arise when this autoimmune condition affects the nail bed, leading to pitting, ridges, and separation.

5. Diabetes

Poor circulation and neuropathy in diabetics increase the risk of thickened toenails. Are thick toenails a sign of diabetes? Yes, especially when paired with slow-healing wounds.

6. Other Causes

  • Thyroid disorders
  • Circulatory issues
  • Genetics (are thick toenails hereditary? Sometimes!)

Thick Toenails Without Fungus

Not all thick toenails stem from fungus. Aging, injury, or conditions like psoriasis can cause thick toenails without fungal infection. Differentiating between fungal and non-fungal causes is essential for proper treatment.

Symptoms and Diagnosis

Signs of Thick Toenails

  • Hard, dense nails that resist trimming
  • Discoloration (yellow, brown, or white streaks)
  • Pain when wearing shoes
  • Brittle or split texture

How Are Thick Toenails Diagnosed?

A podiatrist or dermatologist will:

  1. Conduct a visual inspection to assess nail texture and color.
  2. Perform a nail biopsy or fungal culture to confirm onychomycosis.
  3. Review medical history for conditions like diabetes or psoriasis.

When to See a Doctor:

  • Severe pain or signs of infection (redness, swelling).
  • Sudden thickening without obvious cause.
  • Pre-existing conditions like diabetes.

The right treatment depends on the cause. Below are proven methods to manage thickened toenails:

Medical Treatments

Antifungal Medications

  • Oral antifungals (terbinafine) or topical creams (clotrimazole) combat fungal infections.
  • Requires months of consistent use for toenails to grow back healthy.

Laser Therapy

  • Targets fungal cells with minimal side effects.

Nail Removal

  • Surgical or chemical removal is reserved for severe cases.
