Dry, flaky skin

Many people who are deficient in iodine experience dry, flaking skin. According to some research, up to 77% of patients with low thyroid hormone levels may develop dry, flaky skin. Thyroid hormones, which include iodine, aid in the regeneration of skin cells. When thyroid hormone levels are low, this regeneration is less frequent, which may result in dry, flaky skin.

Thyroid hormones also assist the body in sweat regulation. People with low thyroid hormone levels, such as those suffering from iodine shortage, sweat less than those with normal thyroid hormone levels. Because perspiration keeps your skin wet and moisturized, a lack of sweat might be another reason why dry, flaky skin is a typical sign of iodine deficiency.
