Some systemic diseases cause nails to blanch. Usually these diseases do not just cause a few white spots. A huge part if not the entire nail is affected. Liver and kidney diseases can lead to white nails. Sometimes it’s just a fungal nail infection. Other diseases associated with white spots on nails include sickle cell anemia and Hodgkin’s disease, Addison’s disease and pellagra.

In the event that you have white spots on your nails, how do you go about treating them? Well, treatment will depend on the cause. Several tests can be taken to ascertain the real cause of them. Mycology or nail biopsy can be carried out by a dermatologist. Blood tests are carried out only if systemic illnesses are a likely cause. Tests are carried out only when there are no obvious causes of the spots. Antifungal treatment can be used in case fungal infection is the cause. However, the white spots themselves cannot be treated. They have to be left to grow out naturally until they can be cut out or filed off.
Preventive mechanisms such as using nail polish and hardeners moderately, cutting nails short and moisturizing them can help reduce the chances of getting white spots. The nails shouldn’t also be cut too low. Nail-strengthening serum is recommended for those that do nail polishing frequently. Eating food that contains zinc such as spinach and Vitamin A like carrots frequently is good for the growth of the nails
