If you’ve ever made an appointment with a dermatologist, you might have noticed one of their pre-appointment instructions was to remove your nail polish. But why? According to women’s health expert and advocate Marla Ahlgrimm, it is because your fingernails say a lot about your overall health. Read on as Ahlgrimm answers reader questions about the fingernail/health connection.
Q: I’ve recently noticed a dark streak underneath my fingernail. Should I get that checked out?
Marla Ahlgrimm: Yes, dark streaks that run from the cuticle to the tip may indicate a potentially deadly skin cancer known as melanoma. Some fungal infections can also turn the nail bed dark green or gray. A blue tint underneath the nails could be a sign of a circulatory problem involving the lungs or heart.
