Doctor, do I have a thyroid disease? Will I need medication for life? These are the questions asked by hypothyroid patients when prescribed a thyroxine supplement.
Hypothyroidism (HYPT) is a condition wherein the secretion of the thyroid hormone (thyroxine) by the gland is reduced. The bandmaster of the endocrine system, the thyroid, controls the body metabolism—the rate at which food is converted into energy. The metabolism controls your heart rate, body temperature and how well you burn calories. In HYPT, your metabolism slows down and you become sluggish.
Common causes of HYPT are iodine deficiency (previously widespread but now less), ageing, post-autoimmune and viral thyroid infections (thyroiditis), longstanding use of certain drugs etc, all of which are owing to primary thyroid affliction. There are other rarer secondary (in the pituitary gland) and tertiary (in the hypothalamus of the brain) causes, which I will not allude to. Full Story
