Thyroid disfunction is a problem for many people, mostly women. If your thyroid produces too few hormones you will be hypothyroid and in severe, prolonged cases, low thyroid hormones can cause a myxedema coma. This condition is mostly diagnosed in elderly women, so if thyroid disease runs in the family or if they are already being treated for low thyroid, be aware of this condition. You could save a life.
On the other side of thyroid disfunction, hyperthyroidism is an excess of thyroid hormones. The most severe result of too many hormones is know as a thyroid storm and will lead to shaky hands, your heart racing, sweating and low blood pressure. If this condition is not treated, it can lead to a coma or even death.
