Ever wonder why your nails are so brittle, yellow, or otherwise discolored? Though you may not know it, these seemingly harmless symptoms may indicate you have some underlying health issues.
According to John Anthony, MD, a dermatologist at the Cleveland Clinic in Ohio and Debra Jaliman, MD, a New York City-based dermatologist and author of "Skin Rules,"Â there are certain nail symptoms that definitely shouldn't be ignored. Here's what eight different nail conditions are signaling about your health.
1. Yellow Nails
According to WebMD, one of the most common causes of yellow nails is a fungal infection. But in rare cases, they also say that it can indicate a more serious condition such as diabetes, thyroid disease, or lung disease. Smoking can also stain the nails yellow.
2. Cracked or Brittle Nails
Dr. Jailman says cracked or brittle nails can be a sign that the nail plate is extremely dry. The condition has also been linked to thyroid disease. Hypothyroidism sometimes causes this side effect as well.
3. Pitted Nails
According to MedicineNet, nail pitting is caused by the defective development of the layers of the nail plate, and it is common for those suffering from psoriasis.
