Brittle or Weak Nails May Signal More Than Aging
Brittle, peeling, or weak nails are common and are often caused by everyday factors such as frequent handwashing, water exposure, harsh chemicals, or repeated use of nail polish. But sometimes, nail changes can be linked to an underlying health problem.
1. Nutritional Problems
Low levels of certain nutrients, including iron, may contribute to changes in the nails. Poor overall nutrition can also affect healthy nail growth.
2. Thyroid Problems
Both an underactive and overactive thyroid can sometimes cause changes in nail growth and appearance.
3. Fungal Infection
A fungal nail infection may make nails thick, discolored, crumbly, or easier to break.
4. Skin Conditions
Conditions such as eczema or psoriasis can affect the nails and cause changes in their texture or shape.
5. Repeated Exposure to Water or Chemicals
Frequent wetting and drying of the hands, cleaning products, and nail-polish remover can weaken nails over time.
What Can You Do?
Keep nails trimmed, wear gloves when using cleaning products, moisturize your hands and nails regularly, and avoid picking or biting your nails.
If your nails suddenly become weak, change color or shape, develop dark streaks, or don’t improve despite good nail care, talk with a doctor or dermatologist.
Bottom line: Weak nails don’t automatically mean you have a vitamin deficiency or serious disease. But persistent or unusual changes can be worth checking, especially when they occur along with other symptoms.
