Signs of Iodine Deficiency
Several physical signs may indicate an iodine deficiency, including hair loss and changes in eyebrow density. Losing the outer third of eyebrows can suggest a problem with thyroid hormones, as iodine is crucial for their production. An enlarged tongue, weight gain, and hoarseness are additional indicators of potential iodine insufficiency, as the thyroid struggles to function without adequate iodine. In particular, unexplained weight fluctuations and elevated estrogen levels may manifest when iodine intake is low, affecting overall metabolic health.
