Published on April 7, 2016 by HTC Team

Nail whitening is very common and happens mostly due to trauma to the nails or skin disease. One of the biggest myths regarding nail whitening is that it happens due to deficiency of calcium. There are no minerals or vitamins responsible for discoloration of nails.

But, the nail having white lines, patches or complete discoloration can be due to many reasons. There are different types of nail whitening, it could be partial or complete. It could also be a sign of a bigger disease inside the body organs. Causes and effects of nail whitening are discussed below in brief:

  • Small white patches on nails can be due to nail biting or trauma. This happens mostly on toenails and doesn’t require any medical attention, as the nails generally outgrow within a period of 8 to 12 months.
  • Longitudinal white lines on the surface of nails could happen due to genetic causes and no treatment is required for it.
  • Brittle and thicker white nails along with white patches on the body could be an indication of a skin disease commonly known as Psoriasis.
  • In the case of complete whiteness of nail, it happens due to one of the two reasons: a) deficiency of kidney proteins or b) hypoalbuminemia, which is a symptom of malfunctioning kidneys. Immediate treatment by a specialist is advised in such case.
  • Thickening of nail plate along with whiteness could be due to fungal infection. It can be treated with anti-fungal treatment.
