Brittle Nails: When to Get Checked and Which Results to Watch

Brittle nails, characterized by nails that are dry, cracking, or splitting, can be more than just a cosmetic concern. While often caused by environmental factors, they can also signal underlying health issues that might require attention. Understanding when to seek medical advice and which lab tests to consider can help address the root cause of brittle nails.

What are brittle nails?

Brittle nails are nails that break, chip, or split easily. They may feel dry or rough and can be accompanied by other changes such as discoloration or a change in shape. While some degree of nail brittleness is normal, especially with age or exposure to harsh chemicals, persistent or severe brittleness may indicate an underlying health condition.

Common causes of brittle nails

Brittle nails can result from various factors, including:

• Environmental exposure: Frequent exposure to water, detergents, or harsh chemicals can strip the nails of their natural oils, leading to dryness and brittleness.
• Nutritional deficiencies: Lack of essential nutrients such as iron, biotin, or zinc can weaken nails. Iron deficiency anemia, in particular, is known to cause brittle nails.
• Medical conditions: Conditions like hypothyroidism, psoriasis, or fungal infections can affect nail health.
• Aging: As we age, nails naturally become drier and more brittle.

Lab tests to consider

If you are experiencing brittle nails, a healthcare provider may suggest certain lab tests to identify any underlying issues:

• Complete Blood Count (CBC): This test can detect anemia or other blood disorders that might contribute to nail brittleness.
• Thyroid function tests: These tests measure levels of thyroid hormones to check for hypothyroidism, which can cause brittle nails.
• Nutrient level tests: Tests for iron, zinc, or biotin levels can determine if a deficiency is contributing to your symptoms.

Frequently asked questions

When to see a doctor

If your nails are persistently brittle despite taking preventive measures, or if you notice additional symptoms like changes in nail color, shape, or thickness, it's advisable to consult a healthcare provider. They can help determine if an underlying medical condition is affecting your nails and recommend appropriate tests or treatments.
