5. Fragile, Splitting, or Peeling Nails
- Often caused by repeated exposure to water, soaps, or cleaning chemicals.
- Ongoing brittleness may also be linked to thyroid problems or deficiencies in nutrients such as iron or biotin.
- If nails remain weak despite proper care, a medical evaluation may help identify the reason.
6. Spoon-Shaped Nails (Koilonychia)
- Nails that curve upward like a spoon may be connected to iron-deficiency anemia.
- If this appears with symptoms like tiredness or weakness, checking iron levels can be helpful.
7. Clubbing (Rounded Fingertips and Curved Nails)
- In this condition, the fingertips enlarge and nails curve downward over time.
- It can sometimes be related to lung or heart disorders.
- Because it develops gradually, people often overlook it—medical assessment is advisable.
8. Horizontal Grooves (Beau’s Lines)
- Deep horizontal ridges may form after severe illness, infection, or physical stress.
- They indicate that nail growth temporarily slowed or stopped.
- Repeated grooves could signal an underlying health concern.
When to Pay Attention
Fingernails grow slowly, which means changes might reflect events that happened weeks or even months earlier. Not every unusual nail appearance indicates a serious issue. However, you should seek medical guidance if nail changes are sudden, persistent, or accompanied by other symptoms.
