Brittle and breaking toenails are a common problem with several possible causes. It's often due to a combination of factors rather than a single culprit.
Common Causes of Brittle Toenails:
- Aging: As we age, the growth rate of our nails slows, and the protein structure of the nail plate changes, making them more brittle and prone to breaking. [Source: Better Health Channel, MedlinePlus Medical Encyclopedia]
- Dryness: Repeated exposure to water and harsh chemicals, frequent washing, and low humidity can dry out your toenails, leading to brittleness and breakage. This is a very common cause. [Source: WebMD, Healthline, American Osteopathic College of Dermatology, SkinSight]
- Nutritional Deficiencies: Lack of essential vitamins and minerals, such as biotin, iron, and zinc, can weaken nails, making them more prone to breaking. [Source: VETzInsight (While this source focuses on dogs, the principle applies to humans as well.)]
- Underlying Medical Conditions: Certain health conditions like psoriasis, thyroid disorders, and iron-deficiency anemia can affect nail health and cause brittleness. [Source: Initial reference provided]
- Medications: Some medications can have side effects that impact nail health, leading to dryness and breakage. [Source: Initial reference provided]
- Fungal Infections: Fungal infections can cause discoloration, thickening, and brittleness of the toenails. [Source: Entire Podiatry]
Improving Toenail Health:
To address breaking toenails, consider these steps:
- Moisturize Regularly: Apply cuticle oil or a moisturizer specifically designed for nails to keep them hydrated.
- Limit Water Exposure: Wear protective gloves when washing dishes or cleaning. Allow your feet to air dry thoroughly after showering or swimming.
- Improve Diet: Ensure you're consuming a balanced diet rich in vitamins and minerals crucial for nail health. Consider a biotin supplement after consulting with your doctor.
- Gentle Nail Care: Avoid harsh nail polish removers and file your nails gently in one direction.
- Consult a Doctor: If the problem persists or is accompanied by other symptoms, seek professional medical advice to rule out any underlying medical conditions.
