7. Clubbing (Rounded, Enlarged Nail Tips)
Clubbing occurs when the fingertips enlarge and the nails curve downward over time. This condition can develop gradually and is sometimes linked to lung or heart disease. Because it often progresses slowly, many people don’t notice it right away.
If you suspect clubbing, a medical evaluation is recommended.
8. Horizontal Lines (Beau’s Lines)
Deep horizontal grooves across the nail may appear after severe stress, illness, or infection. They can indicate that nail growth temporarily stopped due to physical stress on the body. While they may grow out over time, recurring lines could signal an underlying health issue.
