As you age, your nails naturally become more brittle and prone to discoloration. Nails also thicken as you age, which can increase your risk of ingrown nails and fungal infections. You might also develop circulatory problems as you age or need to use certain medications that can contribute to nail problems. Aside from nail problems due to aging, infections, trauma, nutritional deficiencies and hormone imbalances can also cause nail problems. Check with your primary care provider if you develop changes in the appearance or texture of your nails.
Identification
Fungal infections in nails cause discoloration and abnormal growth. The American Academy of Dermatology indicates that these types of infections occur more commonly on the toenails than the fingernails. Pits, ridges, lines and changed shape can indicate kidney disease and nutritional deficiencies. Ingrown toenails occur when the corners of your fingernails or toenails curve downward into the skin. Redness and swelling in the area might indicate infection. Splinter hemorrhages -- caused by injury or certain medications -- look like red to reddish-brown lines under the nails.
Misconceptions
Eating large amounts of gelatin will not keep your nails strong, but adequate protein consumption might, says Phoebe Rich, adjunct professor of dermatology at the Oregon Health & Science University in Portland. Rich dismisses data that claims gelatin improves nail health as statistically insignificant.
Prevention/Solution
Exposure to harsh cleaners and other irritants can make brittle nails worse. To improve the condition, the American Academy of Dermatology recommends washing primarily the palm side of your hands and avoiding alcohol-based hand sanitizers. The academy also suggests using thick hand creams that contain humectants, like urea, on your hands and nails to strengthen them and increase their flexibility.
Melanoma
If you notice dark spots or streaks on your nails that do not occur from an injury, make an appointment to see your doctor. These types of discolorations might indicate melanoma. Although melanoma -- the deadliest form of skin cancer --- can occur at any age, Medline Plus says that it is more common in older adults.
Warning
Changes in your nails can serve as an early indicator of serious health issues that afflict many elderly people. According to the American Academy of Dermatology, white nails may indicate liver diseases while a red nail bed can indicate heart conditions. Yellow, thickened nails that grow slowly can point to lung diseases. A nail that is half-pink and half-white might be due to kidney diseases.
