Pay close attention to the causes and keep in mind that more than just one cause can lead to the thickening of the toenails at the same time.

Why do Toenails get Thick?

One of the most important factors that contribute to the thickening of the toenails is aging. As we get older, our toenails start to grow at a much slower rate, a process which ultimately leads to thick toenails. What happens is that the toenail cells practically pile up on top of one another. If a person has frequent injuries or traumas, this can also contribute to the toenails becoming thicker. Impaired blood circulation is believed to be a causative factor for such problems, being related to the improper feeding of the nail with the necessary nutrients to stay healthy.

The toenails can become thicker in those who have had objects repeatedly falling on their feet, in cases of frequent stubbing or by wearing restrictive footwear. Athletes are also subjected to such problems, as the wear and tear mechanism can cause the toenails become thicker. In general, this is caused by the fact that our feet are under a lot of stress – we walk a lot and often wear poor-fitting shoes.

What causes thick toenails?

These are the most common causes that lead to the appearance of thick toenails:

Fungal infection

  • The fungi production is stimulated by the warm and humid environment of the feet
  • Often encountered in those who have a poor hygiene or wear constrictive shoes
  • Can be transmitted from one person to the other, through objects of personal hygiene or taken from public places (showers, locker rooms)
  • Causes the nails to become thicker and yellow in color
  • Other symptoms include itchiness, cracking of the skin and foul odor given by the consumption of skin by the fungi


  • Excessive production of keratin can lead to nail psoriasis
  • Apart from the thickening process, the toenails can change their color, present ridges or grooves on their surface
  • Small holes can appear on the surface of the toenails
  • Fungal infections can also appear in association with nail psoriasis
  • The toenails become brittle, breaking easily

Poor circulation

  • The impaired blood flow to the toenails strips them of their necessary vitamins, minerals and nutrients
  • This problem is often encountered in patients who have been diagnosed with diabetes
  • Fungal infection can appear as a complication, causing the toenails to become thicker

Skin conditions

  • Lichen planus
    • Thick and discolored toenails
    • Frequent association with fungal infection
  • Lupus
    • Thick or splitting toenails
    • Ridges or grooves can also appear on the surface of the toenail
    • Severe cases – nail loss (the entire nail is destroyed)

Injuries/physical damage

  • Frequent injuries to the nail bed caused the toenails to become thicker
  • More commonly encountered in young people


  • Thick toenails, with yellowish discoloration
  • Growth of the nail is also affected – patients describe the toenails as not growing as they are supposed to


  • Different types of trauma can cause a temporary or permanent thickening of the toenails
  • The faster one intervenes in case of trauma, the more reduced the risk of the toenails being affected.
