Fingernails the window to your health
It’s been said that the eyes are a window to the soul, but could the same hold true for our nails? Dermatologists say changes in nail color and texture could indicate a serious health problem.
Your toenails and fingernails protect the tissues of your toes and fingers. They are made up of layers of a hardened protein called keratin, which is also in your hair and skin. Your nails' health can be a clue to your overall health. Healthy nails are usually smooth and consistent in colour.
Nails can provide valuable information about a person’s health. Yellowish nails can sometimes signal lung problems. Half white, half pink nails could be a sign of kidney disease. Red nail beds? Heart disease. Pale or white nail beds? Anaemia.
While dark, long, uniform bands are common among people with darker complexions, when melanoma is present, it often shows up as a pigment change at the cuticle. If your nails separate from the nail bed, it could indicate the skin condition psoriasis.
Brittle nails are one of the most common complaints. They are generally characterized by vertical splitting or separation of the nail plate at the end of the nail. This is often a consequence of aging as the flow of moisture and natural oils to the nail bed declines.
Ingrown toenails typically affect the big toe and occur when a corner of the nail curves downward into the skin. This condition can be very painful and lead to infection. Ingrown toenails are usually caused by improper nail trimming, poor posture, or tight shoes. Nails should always be cut longer than the tips of the toe to prevent the advancing edge of the nail plate from “digging in” to the soft tissue of the nail folds.
This nail abnormality is characterized by a white nail bed with a pink band that is one to two mm wide at the tip. In most cases, all the fingernails are affected, although it can affect a single finger. White nails affects about 80 percent of people who have severe liver disease. It is also seen in people with type 2 diabetes, chronic renal failure, or congestive heart failure and is associated with advancing age as well.
To maintain healthy fingernails, avoid infections, and improve nail appearance, try the following tips:
• Keep your nails clean and dry.
• Avoid nail-biting or picking.
• Apply moisturizer to your nails and cuticles every day. Creams with urea, phospholipids, or lactic acid can help prevent cracking.
• File your nails in one direction and round the tip slightly, rather than filing to a point.
• Don't remove the cuticles or clean too deeply under your nails, which can lead to infection.
• Don't dig out ingrown toenails. Seek treatment if they become bothersome.
• Avoid nail polish removers that contain acetone or formaldehyde.
• Bring your own instruments if you get frequent manicures.
