15 Common Signs Of Iodine Deficiency You Shouldn’t Ignore (List)

Nail Color Discoloration

Discoloration of the nails occurs when the nail becomes brownish, yellowish, or greenish. The discoloration can be seen in both fingernails and toenails.

The discoloration worsens in the winter when a person’s body’s iodine stores are depleted. This may indicate that they are deficient in iodine, a common condition that affects up to 70% of people worldwide. If they have discolored nails, it is crucial to get their iodine levels checked by a doctor. The discoloration can be caused by liver disease, malnutrition, and kidney failure.

If they think they may have an underactive thyroid, this is one symptom to keep an eye out for, but unfortunately, it’s not always easy to tell whether or not it means anything serious! Many other things can cause discolored nails as well (like psoriasis).
