Mehmet Oz, MD, Cardiology, answeredYour nails can be a clue to your overall health. Some common conditions that poor nail health may indicate include thyroid disorder, vitamin deficiency, iron-deficiency anemia, sinusitis, chronic bronchitis, and diabetes. If you are concerned about your nail health or notice any changes in your nails, talk to your doctor.

Poor nail health can indicate many conditions. Kidney disease, lung disease, diabetes, heart disease, and anemia can all cause a person to have poor nail health. See your doctor if you notice any changes in your nail health to check for an underlying medical condition.
