PART 1: THE THYROID & HYPOTHYROIDISM
The thyroid is a small butterfly-shaped gland located at the base of the neck, just below the Adam’s apple. It’s responsible for controlling the body’s metabolism, or the rate at which the body converts food into energy, and for making sure the brain, heart, liver, kidneys, and other organs are working properly.
It does this by creating thyroid hormones that are then circulated through the bloodstream to different parts of the body.
When you have hypothyroidism, the thyroid doesn’t produce, or can’t produce enough thyroid hormones. When your thyroid hormone level decreases, it results in your body’s system slowing down, including your metabolism, which may lead to symptoms such as sensitivity to cold, weight gain, and fatigue.
These are not all the symptoms of hypothyroidism. Your doctor will use a TSH, or thyroid stimulating hormone, test to determine whether you have hypothyroidism.
PART 2: HOW SYNTHROID WORKS
Synthroid is a man-made hormone, identical to the hormone made by the thyroid gland and has the same effect on the body. It replaces the amount of hormone the thyroid is unable to or can no longer make, helping to restore your thyroid hormone levels to the range they need to be.
Because your body needs a precise number of thyroid hormone, it’s important to take Synthroid the right way every day, just as your doctor prescribes. This is because how you take Synthroid can affect how well it works.

SYNTHROID® (levothyroxine sodium) tablets, for oral use is a prescription, man-made thyroid hormone that is used to treat a condition called hypothyroidism in adults and children, including infants. It is meant to replace a hormone that is usually made by your thyroid gland. Generally, thyroid replacement treatment is to be taken for life. SYNTHROID should not be used to treat noncancerous growths or enlargement of the thyroid in patients with normal iodine levels, or in cases of temporary hypothyroidism caused by inflammation of the thyroid gland (thyroiditis).
