Brittle or Weak Nails? Your Body Might Be Trying to Tell You Something
Brittle, splitting, or weak nails are common and often caused by everyday factors like dryness, frequent washing, or nail products. However, changes in your nails can sometimes reflect nutritional issues, health conditions, or changes in your body.
Nail changes alone usually cannot diagnose a disease, but they can be a clue that something deserves attention.
1. Dryness and frequent exposure to water
One of the most common causes of brittle nails is repeated wetting and drying.
Common triggers:
- Frequent handwashing
- Cleaning products
- Long exposure to water
- Dry weather
This can make nails peel, crack, or split.
2. Low iron levels
Iron deficiency can sometimes affect nails.
Possible nail changes:
- Weak or thin nails
- Increased brittleness
- Spoon-shaped nails (nails that curve upward)
Other possible signs of low iron:
- Fatigue
- Pale skin
- Shortness of breath with activity
3. Not getting enough nutrients
Nails need adequate nutrition to grow normally.
Possible contributors:
- Low protein intake
- Vitamin deficiencies
- Mineral deficiencies
A balanced diet with sufficient protein, fruits, vegetables, and whole foods supports healthy nails.
4. Thyroid problems
Both an underactive and overactive thyroid can sometimes affect nails.
Possible changes:
- Slow nail growth
- Brittle nails
- Nails separating from the nail bed
