Fingernails can tell us a lot about our health. So it’s important to look at them for signs of discoloration, ridges, and other qualities that may indicate a medical condition, some of which can be quite serious.
According to the natural health website Mercola.com, the following nail issues can pose problems:
Nails may turn yellow due to age, nail polish, smoking or a fungal infection. However, they may also indicate thyroid disease, diabetes, psoriasis, or respiratory disease.
2) Dry, cracked and brittle
If your hands are frequently exposed to water or you use nail polish remover or cleaning chemicals a lot, they may crack or split. But they could also be caused by a fungal condition or hypothyrodism. In addition, you may have a vitamin A, B or C deficiency.
A nail that curves downward on an enlarged fingertip is clubbed. It may be caused by lung disease, kidney disease, heart disease, inflammatory bowel disease or AIDS.
4) Horizontal ridges
Ridges are often caused by serious illnesses in which the body pauses their growth. Health conditions include psoriasis, diabetes, circulatory disease, zinc deficiency, Hodgkin’s disease and malaria.
Nails that curve upward at the edges and resemble spoons may indicate anemia, hemochromatosis, heart disease, or hypothyroidism.
6) Dark discolorations
If your nails have black streaks or painful growths on them, it may be the result of melanoma, a deadly form of skin cancer.
7) White nails with a pink stripe
Also known as “Terry’s Nails,” this problem could indicate liver disease, congestive heart failure, kidney failure or diabetes.
