When it comes to nail psoriasis, a number of symptoms can occur. The first is pitting of the nails. In addition, the nail may present with a gap underneath it. Portions of the tip may even turn white or yellow, with changes that can be seen as far down the nail as the cuticle. In addition, a chalk-type buildup may show up underneath the nail that may be painful upon touch. Or the nail may turn a yellowish brown color. The nail can even increase in thickness due to a fungal infection called onychomycosis that often occurs in combination with nail psoriasis. (Experts say that 35 percent of those with nail psoriasis also develop a fungal infection.)
Anyone who notices these changes on the nails should see a dermatologist to rule out this and other conditions.
2. Iron Deficiency Anemia
Experts say that iron deficiency anemia is the most common type of anemia. According to the U.S. National Library of Medicine, anemia occurs when the body lacks red blood cells that are healthy. And iron deficiency anemia develops when the body lacks iron, which assists in the production of red blood cells.
This condition can occur for a number of reasons -- from heavy periods to a vegetarian diet. In addition, health issues like Crohn and Celiac disease can cause iron deficiency anemia.
When iron deficiency anemia occurs, the nails can become brittle with elevated ridges. In addition, the nails can take on a unique shape called koilonychia, which looks much like a spoon.
3. Kidney Disease
Kidney disease and nail changes go hand in hand. In fact, doctors say that certain changes in the appearance of the nail can be a sign of acute or chronic kidney disease.
