Iodine deficiency
Iodine is a mineral that is required for appropriate thyroid function and thyroid hormone synthesis. Thyroid hormones have a role in a variety of biological functions, including growth, brain development, and bone health. They also control your metabolic rate. One of the most frequent nutritional deficits, affecting roughly a third of the world's population, is iodine insufficiency.
An enlarged thyroid gland, often known as a goiter, is the most prevalent sign of iodine insufficiency. It may also raise heart rate, produce shortness of breath, and promote weight gain. Severe iodine shortage is associated with substantial injury, particularly in children. It has the potential to induce mental impairment and developmental problems. Some nations require that table salt be enriched with iodine, which has successfully decreased the frequency of deficiency.
