Changes in Your Fingernails/Toenails

Can Signal Larger Health Problems

 

Important information about nail health from the American Academy of Dermatology:

Our nails often reflect our general state of health. Changes in the nail, such as discoloration or thickening, can signal health problems, including liver and kidney disease, heart and lung conditions, anemia, and diabetes. Symptoms that could signal nail problems include changes in color, shape and/or thickness, swelling of the skin around the nails, bleeding or discharge, and pain. See your dermatologist for the successful diagnosis and treatment of nail problems, and to find out if they are indicating a greater issue with your overall health.

Nail growth

  • Fingernails grow faster than toenails — especially on one’s dominant hand.

  • On average, fingernails grow 3.5 mm per month, while toenails grow about 1.6 mm per month.1

  • Nail growth rates depend on age, health status, time of year, activity level and heredity.

  • Women’s nails grow more slowly than men’s, except possibly during pregnancy.

  • Nails grow more rapidly in summer than in winter.

  • Nail growth is affected by disease, nutrition, medications, trauma, chronic illness, fever and the aging process.

Nail problems

  • Nail problems make up about 10 percent of all dermatologic conditions.2

  • Nail problems usually increase throughout life and affect a high number of senior citizens.3

  • Fungal infections cause about half of all nail disorders.4 They are more common in toenails because the toes are confined in a warm, moist, weight-bearing environment.

  • Melanoma, the deadliest form of skin cancer, can grow under the nail in rare cases. Such melanomas may be mistaken for injuries, so a dermatologist should be consulted if a dark-colored streak appears within the nail plate, if the nail discoloration does not gradually improve or if the size of the streak increases over time.5

  • Other common nail problems include:

  • White spots after an injury to the nail.

  • Vertical lines, known as splinter hemorrhages, under the nails caused by nail injury or certain drugs and diseases.

  • Bacterial infections, most often due to injury, poor skin hygiene, nail biting, finger sucking or frequent exposure to water.

  • Ingrown toenails, caused by improper nail trimming, poor stance, digestive problems or tight shoes.

  • Do not try to self-treat ingrown toenails, especially if they are infected. See a dermatologist.

  • Nail problems are more common in those with diabetes or poor circulation. At the first sign of a problem, see a dermatologist.

 

Tips for keeping nails healthy

  • Keep nails clean and dry to prevent bacteria from collecting under the nail.

  • Cut your fingernails and toenails straight across and rounded slightly in the center. This will keep your nails strong and help you avoid ingrown toenails.

  • When toenails are thick and difficult to cut, soak feet in warm salt water (one teaspoon of salt per pint of water) for five to 10 minutes, and then apply urea or lactic acid cream. This softens the nails, making them easier to trim.

  • Wear proper-fitting shoes and alternate shoes on a regular basis. Tight shoes can cause ingrown toenails.

  • Do not bite your fingernails; this can transfer infectious organisms between your fingers and mouth. Nail biting also can damage the skin around your fingers, allowing infections to enter.

  • Apply a cream to moisturize your nails, especially after removing nail polish, since most polish removers contain chemicals that dry the nails.

  • If you want to wear a bright red or orange polish, prevent discoloration by applying an extra layer of base coat. If your nails become yellowed and discolored from the polish, they should return to their normal color over several weeks if the same polish is not reapplied.

Nail salon safety

  • While most nail salons follow strict sanitation guidelines, consumers should check to make sure that the salon, the manicure stations, the footbaths and the tools are clean, and that the technicians wash their hands between clients.6

  • Consumers who get frequent manicures and pedicures should bring their own tools to the salon.

  • Don’t let a nail technician cut or push back your cuticle. It may allow an infection to develop.

  • Do not wear artificial nails to cover up nail problems, as this may make those problems worse. Artificial nails are not recommended for people who are prone to fungal infections or have brittle nails. For people with healthy nails, artificial nails can be fine as long as they are not worn continuously.

  • Don’t shave your lower legs for at least 24 hours before you get a pedicure. If you nick yourself while shaving, a pedicure could put you at risk for an infection.

  • If you experience itching, burning or any type of allergic reaction to a nail cosmetic, see a dermatologist.

Find out how you can protect your healthy skin from skin cancer.

Spring has sprung and before long we will all be enjoying the benefits of summer. Maybe you and your family are planning to take that much-needed beach vacation or you are planning to soak up the rays with picnics and daily walks. However you choose to celebrate summer, your Warrenton dermatologist Dr. Juan-Carlos Caballero wants to make sure that everyone keeps their skin safe during the Skin Cancerwarm months and throughout the year.

The Best Ways to Prevent Skin Cancer

There are so many things you can do to protect your skin from the damaging rays of the sun and the sooner you start the better. Here are some handy tips to follow:

Limit Time in the Sun

Did you know that the sun’s rays are strongest between the hours of 11AM and 4PM? This means avoiding the sun as much as possible during these times and opting for off times to enjoy the great outdoors.

Seek the Shade

Of course, your Warrenton skin doctor knows that people don’t plan to spend the majority of their summers indoors, which is why these next few tips will help with protecting yourself while outside. Whenever you do go out this summer (even if it’s between 11AM and 4PM or not) you will want to seek shade whenever possible to limit exposure, whether this means lying under an umbrella or picnicking under a tree. Also, opt for protective clothing that covers your arms and legs, and don’t forget to wear a brimmed hat and sunglasses.

Cloudy Days Don’t Protect

You may see a cloudy summer day and think that you don’t have to put on sunscreen or wear protective clothing, but think again! About 80 percent of the sun’s rays can easily penetrate through clouds and fog. So don’t think you’re impervious to a sunburn on any given day.

Wear Sunscreen Daily

This rule should always go without saying but so many people don’t wear sunscreen at all let alone correctly. Opt for sunscreen with an SPF of 15 or more that protects against both UVA and UVB rays. Apply it about 15 minutes before going outside and reapply every two hours (or reapply after sweating or swimming). Not sure what kind of sunscreen is right for you? We would be happy to help!

Your skin health is important, so it’s also important that you turn to the skin care experts in Warrenton. Call Warrenton Dermatology & Skin Therapy Center today to schedule your next skin cancer screening.
