What Your Nails Say About Your Health (cont.)
Fox agrees there is no need to run to the nearest cardiologist if your nail beds turn red. "It could very well be from nail polish," he says. Before assuming the worst, it's important to look at more common explanations, such as bruises, bleeding beneath the nail, and fungal infections.
When to See a Dermatologist
Many common nail disorders stem from fungal infections, which can cause the nails to crack, peel, and change color and texture. These infections often prove difficult to treat and may require professional help, including prescription antifungal medications. Fox says it's best to see a dermatologist if symptoms persist, especially if the nails start to dislodge from the base or you experience pain and swelling.
Changes in texture, shape, or color that aren't due to a bruise or fungal infection, including irregular growth, pitting or holes in the nails, dark brown streaks beneath the nail and cuticle, or long-standing warts on the nail bed are particular concerns. According to Lior, they can indicate skin cancer. "Warts around the nails have a tendency to develop into squamous cell cancer," she tells WebMD. "If patients see a dark discoloration involving the cuticle, then we worry about melanoma," the deadliest form of skin cancer.
Fox advises reporting these types of changes to a specialist as soon as possible. "Dermatologists are well-trained in deciphering between innocuous and serious nail conditions, as well as determining when a change requires further testing."
