The human body provides many ways to signal underlying conditions and disorders. For example, fever can be identified by elevated body temperature, while liver diseases can manifest through yellowing of the skin and abdominal swelling.
Interestingly, certain health issues can also be detected by simply examining the nails. Below are some conditions and disorders that may be indicated by changes in nail appearance:
-
Pale or bluish nails.
This can be a sign of anemia or a blood disorder. Anemia occurs when the body lacks enough healthy red blood cells to carry oxygen.
-
Slow color return after pressing on the nail.
If the nail’s color does not quickly return to normal after being pressed, it may indicate problems with blood circulation.
-
White spots on the nails.
Contrary to the belief that white spots signal a lack of calcium or zinc, these are usually caused by past nail injuries.
-
Clubbing of the nails.
When the nails curve downward and appear bulbous, it can be a sign of respiratory issues like asthma or even heart disease.
-
Spoon-shaped nails.
Nails that grow outward resembling a spoon may indicate anemia, liver disorders, or severe trauma to the fingertips.
-
Pitted nails.
Small, needle-like depressions on the nail surface may be a sign of psoriasis, a condition that causes inflammation of the skin.
-
Dark spots under the nails.
These can indicate melanoma, a serious form of skin cancer that requires immediate medical attention.
-
Horizontal lines (Beau’s Lines).
These grooves running across the nails may be a sign of a significant health event, such as severe fever. They can also indicate diabetes or zinc deficiency.
Your nails can provide valuable clues about your overall health. While some changes may be harmless, others could signify more serious conditions. If you notice any unusual changes in your nails, consult a healthcare provider for proper diagnosis and treatment.
