Do you know that nails reflect your overall health? Many things can happen in the nails that can indicate skin and systemic problems. If your nails are turning black, white or yellow, or if there are rims developing, it’s a warning sign that something is wrong with your health.
If you have stress, side-to side lines will appear on your nails. The nail’s surface should be smooth, but if you notice ripples developing, it can be an early sign of psoriasis or inflammatory arthritis. Yellow nails can be a sign of skin cancer, psoriasis or diabetes. The nails can turn black due to an injury, but if it is not due to an injury, it can be a sign of perilous skin cancer.
