Don’t File This Away! 15 Nail Changes That Could Signal To Serious Health Issues

Your nails are not just a canvas space for manicures and polish. They are body's natural indicator to your overall health, providing vital signals about possible underlying medical conditions. An alteration in nail color, texture, or shape may be a minor issue, yet at times it may portray serious illness. From deficiencies to illnesses, your toenails and fingernails may be sending you important messages.

Around 30% of Americans manage stress by biting their nails. Besides scratching itches, nails reveal health insights. Composed of keratin, the same protein as hair and skin, nails protect sensitive nerve endings. Since keratin supports various bodily functions, vitamin deficiencies or diseases often cause noticeable changes in nail color, strength, or shape.

Your nails hold the key to important health information, and they can help identify diseases at an early stage. If you observe sudden changes in your nails, visit a dermatologist or healthcare professional. Healthy nails are not merely a matter of appearance—they reflect your health.

Here's what you should know about 15 nail changes and what they might indicate for your health.

<h2>1. Horizontal White Streaks- Sign of Nutrient Deficiency or Organ Damage</h2>

If you observe horizontal white bands (Muehrcke's bands) across your nails, you may be experiencing protein or zinc deficiency. Such bands imply that your nails did not receive necessary nutrients or sufficient blood supply while growing. Sometimes, they are a sign of more severe ailments like kidney disease or liver dysfunction. If you observe them, see a doctor to exclude severe deficiencies or organ problems.

<h2>2. Brown Vertical Stripe- Possible Indication for Melanoma</h2>

A dark or brown stripe from the cuticle to the end of the nail may be a sign of subungual melanoma, which is skin cancer. Pigmentation change due to hormonal fluctuations or medications is possible, but broadening, darkening, or extension of the stripe requires urgent medical consult.

<h2>3. Ridges on Nails- Aging or an Indicator of Systemic Disease?</h2>

Vertical ridges on nails are normal with aging and are generally harmless. Deep horizontal ridges, or Beau's lines, signify an interruption in nail growth. These ridges may be due to serious illness, high fever, major surgery, or even chemotherapy. Sudden ridges you see may be related to recent serious health stress.

<h2>4. Horizontal Depression on the Thumb- Habit Tic Deformity</h2>

A washboard-shaped horizontal depression on the thumbnail is usually caused by habit tic deformity, a habit resulting from repeated picking or rubbing of the index finger over the cuticle. Although not necessarily a health issue, discontinuing the habit will enhance <span>nail health</span> and appearance.

<h2>5. Brittle Nails- Associated with Malnutrition and Thyroid Disease</h2>

If your nails are brittle, splitting, or breaking, you might have brittle nail syndrome (onychoschizia). Brittle nail syndrome is usually caused by a lack of nutrients, dehydration, or overuse of chemicals such as acetone. Brittle nails may also be an early sign of iron deficiency anemia or thyroid disease. A diet with adequate nutrients and hydration can strengthen your nails.

<h2>6. Pitted Nails- Sign of Psoriasis or Alopecia Areata</h2>

Small pits or dents in the nails can be a sign of psoriasis, a long-term skin condition. Pitting is also associated with psoriatic arthritis and alopecia areata, an autoimmune condition leading to hair loss. If you notice pitted nails, see a dermatologist to find out the cause and how to treat it.

<h2>7. Pale Nails- Anemia, Heart Disease, or Liver Problems?</h2>

Pale or ghostly nails can be a sign of anemia, a condition in which your red blood cell count is low. Extreme paleness may also be related to heart disease or liver disease. In association with fatigue, dizziness, or shortness of breath, medical assessment is required.

<h2>8. Blue Nails- Deficiency of oxygen and circulatory problems</h2>

A blue color to the nails tends to indicate insufficient oxygen, possibly resulting from respiratory disease, heart disease, or Raynaud's disease. If your nails consistently have a blue or purplish color, consult a doctor to determine oxygen levels and circulatory health.

<h2>9. White Spots- Trauma or Fungal Infections</h2>

White spots on the nails (punctate leukonychia) are usually harmless and occur from slight trauma. Persistent or multiple white spots might, however, suggest an infection or hypersensitivity reaction to nail cosmetics.

<h2>10. Red Streaks- Indicator of Infection of the Heart Valve</h2>

Red streaks or splinter hemorrhages beneath the nails can indicate endocarditis, an infection of the heart's inner lining. If you have other symptoms like fever, weight loss, or muscle pain, get immediate medical care.

<h2>11. Yellow Nails- Sign of Diabetes, Fungal Infection, or Lung Disease</h2>

Yellow, thickened nails that grow slowly are a hallmark of yellow nail syndrome, and they may accompany respiratory problems. Yellow discoloration can result from smoking, fungal infection, thyroid disease, or diabetes, too. Resolving the causative factor often improves nail appearance.

<h2>12. Clubbing of Nails- Warning Sign for Lung or Liver Disease</h2>

When nails get rounded and bulbous at the tips, it is referred to as clubbing. Clubbing is usually linked with chronic lung disease, gastrointestinal diseases, or liver cirrhosis. If your nails are clubbed, visit a doctor to check for underlying conditions.

<h2>13. Severely Bitten Nails- Clue to Anxiety or OCD</h2>

Prolonged nail-biting has the potential to disfigure nails and the skin around them, leaving them susceptible to infection. On occasion, hyper-nail biting is one of the signs of obsessive-compulsive disorder (OCD). Avoiding the precipitating stimuli and learning stress-coping methods will help individuals discontinue this behavior.

<h2>14. Dull Nails- Indicator of Sleep Deprivation</h2>

Lack of sleep can impact your nail health, making them weak and lifeless. If you’re consistently getting less than the recommended eight hours of sleep per night, your nails may be showing the toll of fatigue.

<h2>15. Nail Separation (Onycholysis)- Symptom of Thyroid Disease or Allergies</h2>

If your nails start lifting from the nail bed, it may be due to onycholysis. This condition is commonly associated with thyroid disorders, fungal infections, lupus, or allergic reactions to nail products. Addressing the root cause is essential for recovery.
