Toenails Are Health Indicators, Too
Toenail color, breakage, streaks, and spots give you clues about your health. Whitish toes are a common symptom of anemia, while white streaking indicates a protein deficiency. Yellowing could be from painting your toenails too often or fungal infection, but it also might be caused by a liver condition or diabetes. Some other colors to watch for include black (which could indicate bruising or a circulatory issue), gray (which indicates malnutrition or arthritis), and blue (which could be Raynaud’s disease or circulatory problems). Dark streaking could even tell you that you have melanoma, a dangerous form of skin cancer.
