What Your Fingernails Reveal About Your Health

Take a moment to examine your fingernails. If they’re not adorned with polish (and let’s be honest, during a pandemic, they likely aren’t), you might notice various characteristics. Are they long, robust, and hard? Or perhaps thin and flexible? Do they tend to peel? Some individuals may observe vertical or horizontal ridges, while others might notice small white spots on some nails. Changes in color, thickness, and separation from the nail bed can provide valuable insights into your overall health.

It makes sense: your fingernails are composed of keratin, the same material found in your hair and the outer layer of your skin. The visible part of the nail is dead, which means trimming them won’t cause any pain (a helpful tidbit for parents with curious toddlers!). Fingernails typically grow from the cuticle at a rate of approximately 3.5 millimeters per month, or about a tenth of a millimeter each day. If you lose a nail, it can take up to six months to fully regenerate, and longer for thumbs. They tend to grow faster on your dominant hand, during the warmer months, and throughout the day. Interestingly, nail growth accelerates during pregnancy but slows down during nursing.

Given their rapid growth and visible renewal, nails can reveal a lot about your health status. Are you dealing with thyroid issues or nutritional deficiencies? Your nails may be signaling concerns. Here’s a breakdown of some common nail conditions and what they could signify.

Vertical Lines on Your Nails

One prevalent issue many people experience is the appearance of vertical lines on their nails. According to the Cleveland Health Clinic, these lines can emerge during stressful periods—something we can all relate to! Prolonged stress can manifest in various ways, including your nails.

Brittle or Splitting Nails

Brittle, cracking, or splitting nails can indicate several underlying issues. Malnutrition is one possibility, as is aging or lifestyle factors. Additionally, thyroid disease and anemia can contribute to these symptoms. Thyroid disease often results in insufficient hormone production, which can be diagnosed through a blood test. Anemia occurs when red blood cells lack adequate hemoglobin, essential for oxygen transport throughout the body.

Spotting Issues

You might notice different types of spots on your nails, some of which are benign while others require medical attention. Random white spots, known as leukonychia, are typically harmless but can suggest nutritional deficiencies or infections during growth. Changes in nail color are another common concern raised by dermatologists. Discoloration that affects the nail from base to tip could be benign or indicate serious conditions, such as melanoma. If you notice any change in color or texture, consult your doctor.

Color Changes in Your Nails

What do different nail colors mean? Pale nails could signal malnutrition, anemia, congestive heart failure, or liver disease. Yellow nails, especially if not caused by nail polish or smoking, might indicate a fungal infection, chronic bronchitis, or even more serious conditions like lung disease or diabetes. Blue nails suggest inadequate oxygen levels, pointing towards potential heart or lung issues. If discoloration is due to a bacterial infection, you may also notice redness or swelling.

Ridges on Your Nails

Beau’s Lines, which are horizontal ridges across the nails, can indicate malnutrition or specific vitamin deficiencies, particularly zinc. They may also signal diabetes or previous serious illnesses, such as pneumonia or scarlet fever, during the nail’s growth period.

Lifting Nails

If you notice your nail lifting from the nail bed, it can have various causes, ranging from medication side effects to thyroid disease, pregnancy, fungal infections, or trauma. It’s advisable to get this symptom checked out.

Fungal Infections

While more prevalent in toenails, fungal infections can also affect fingernails. Symptoms include yellowing, crumbly ends, thickness, or nails separating from the nail bed. Curling or distorted shapes may also indicate an infection.

So, take a closer look at your nails. They can provide valuable insights. If you observe any of the symptoms mentioned, don’t rely on self-diagnosis. Instead, consult your doctor. They can provide reassurance and help you understand your health better.
