11 Clues That the Fingernails Give Us About Our Overall Health
Ever thought about the idea that your fingernails might hold crucial clues about your overall health? Beyond their seemingly ordinary appearance, your nails can subtly indicate potential health concerns within your body. Let’s delve into the significant messages your fingernails might be conveying about your well-being.
Dark Streak
Medically known as Acral lentiginous melanoma, it is a condition that presents as a new or changing dark streak on your fingernail or toenail and should never be ignored. It could be a sign of melanoma, the most serious skin cancer. While not every dark streak indicates melanoma, consulting a dermatologist is crucial for a proper evaluation. When detected and treated early, melanoma is highly curable, often requiring minimal intervention.
Greenish Black Color
A greenish-black color (or Paronychia) on your nails can be a sign of nail infection, often caused by bacteria. Ignoring such an infection can worsen symptoms, including pain and tenderness. The good news is that timely treatment can make a world of difference. Seeking medical attention alleviates discomfort and effectively clears the infection, restoring your nail’s health and appearance.
Nail Lifting Up
When a nail starts to lift and exhibits white discoloration (Onycholysis), it signals something isn’t quite right. This detachment can be attributed to various factors, such as fungal infection, Psoriasis, or Injury from an aggressive manicure.
Regardless of the cause, you must consult a dermatologist when you notice a nail lifting up. Such a condition may require treatment, especially if an infection is present.
Redness and Swelling Around a Nail
Redness and swelling around your nail are usually signs of infection, so taking action promptly is crucial. Early diagnosis often allows for relatively straightforward treatment, which may involve soaking the affected area and taking antibiotics. However, if an open sore develops, it’s a sign that the infection has progressed, and more intensive treatment will be necessary.
Pitted Nails
Dents in your nails or pitting resembling icepick marks can indicate an underlying condition affecting your entire body. Conditions that cause pitted nails include Psoriasis, Atopic dermatitis (eczema), and Alopecia areata.
To receive a proper diagnosis and appropriate treatment, consult a board-certified dermatologist.
Yellow Nails
While wearing red nail polish without a base coat or smoking can contribute to nail discoloration, persistent yellow nails should not be ignored. Yellow nails (Yellow Nail Syndrome) may be associated with various underlying conditions, including Lung disease, rheumatoid arthritis, and serious nail infection.
If you notice your nails displaying these symptoms, it’s crucial to consult a healthcare professional for a thorough evaluation.
Deep Grooves
When you notice deep grooves that run across the width of your nail, it’s a sign that your nail growth was interrupted at some point. This interruption in nail growth can be caused by fever, injury, chemotherapy, or major stress.
When your nails stop growing, you may observe a gap known as onychomadesis. Consulting a dermatologist or primary care doctor is advisable if you’re unsure what might have caused it.
Ram’s Horn Nails
It is a condition that occurs because of nail thickening and overgrowing (also known as Onychogryphosis) and can be hereditary for some individuals.
However, it can also be associated with certain medical conditions like psoriasis, ichthyosis, or circulatory problems.
Cutting and managing Ram’s horn nails typically needs professional assistance, often from a podiatrist or dermatologist.
Thin Spoon-shaped Nails
Thin, spoon-shaped fingernails that dip down in the middle (a condition known as “koilonychia) are a sign you are iron deficient. Iron deficiency can occur for various reasons, such as inadequate nutrition, gastrointestinal health issues, gluten sensitivity (celiac disease), or high-altitude living.
Correcting the underlying iron deficiency can lead to a significant improvement in your overall well-being and nail health.
Curved Nails
The subtle, gradual curving (or Clubbing) of fingernails is something many people may not immediately notice. However, it can lead to symptoms such as fingertip swelling and nails becoming spongy to the touch.
While curved nails can be a harmless inherited trait, they can also serve as a potential indicator of underlying health issues, including those related to the lungs, heart, liver, stomach, or intestine.
Washboard Nails
If you notice grooves and ridges in the center of your thumb, you may have a habit of picking at or pushing back the cuticles on your thumbnails. It’s common for individuals to engage in this habit without even realizing it.
A dermatologist can help you break this habit and promote the growth of healthy nails.
