Unintentional Weight Gain, Flaky and Dry Skin
Another typical symptom of an iodine deficiency is unexpected weight gain. In healthy people, the metabolism burns calories to generate energy. However, a lack of thyroid hormones due to insufficient iodine would slow down this process. When the metabolic rate is reduced, calories may be stored in the body as fat, resulting in weight gain. Keep in mind that unexpected weight gain does not always indicate a deficiency of iodine. You need to notice other signs and inform your doctor for a precise diagnosis. [2]
Flaky and dry would occur in many individuals with an iodine deficiency. In general, thyroid hormones are important for the regeneration of skin cells. When a lack of iodine causes low levels of thyroid hormone, this process does not happen as frequently. As a result, the skin becomes flaky and dry. Thyroid hormones also help with sweat regulation. Those with low levels of thyroid hormone tend to sweat less. Since sweat keeps the skin hydrated and moist, a lack of sweat would be another reason why this symptom occurs. [3]
