Your thyroid plays an essential role in your body. It produces hormones that help you regulate your body, controlling things like your body temperature and your heart rate. However, in some cases, your thyroid may not produce enough of the hormones that your body requires. This condition, called hypothyroidism, can have a significant impact on your health, affecting the way that your body functions. There are several potential signs that this could be occurring. For example, you may notice a slower heartbeat, weight gain, double vision, cold sensitivity, thinning hair, and goiters, or thyroid nodules.
There are several reasons why hypothyroidism can occur, including potential hereditary diseases. However, it has also been linked to an iodine deficiency. Your body needs iodine to be able to produce thyroid hormones T3 and T4. Thus, sufficient iodine intake is an important part of preventative health care to reduce the prevalence of thyroid disorders.
