Web MD – What is Hypothyroidism?

Hypothyroidism means your thyroid is not making enough thyroid hormone. The thyroid is a butterfly-shaped gland in the front of your neck. It makes hormones that control the way your body uses energy.

WIkipedia – Thyroid

In vertebrate anatomy, the thyroid gland or simply, the thyroid, is one of the largest endocrine glands in the body, and is not to be confused with the “parathyroid glands” (a completely different set of glands). The thyroid gland is found in the neck, inferior to (below) the thyroid cartilage (also known as the ‘Adam’s Apple’) and at approximately the same level as the cricoid cartilage. The thyroid controls how quickly the body uses energy, makes proteins, and controls how sensitive the body should be to other hormones.

What is Hashimoto’s disease?
Hashimoto’s disease is an autoimmune disease that affects the thyroid. It also is called Hashimoto’s thyroiditis (theye-royd-EYET-uhss). The thyroid is a small gland in the front of the neck. The thyroid makes hormones called T3 and T4 that regulate how the body uses energy. Thyroid hormone levels are controlled by the pituitary, which is a pea-sized gland in the brain. It makes thyroid stimulating hormone (TSH), which triggers the thyroid to make thyroid hormone.

Family Doctor – What causes hypothyroidism?

The most common cause of hypothyroidism is an autoimmune disease called Hashimoto’s thyroiditis. Normally, antibodies produced by the immune system help protect the body against viruses, bacteria and other foreign substances. An autoimmune disease is when your immune system produces antibodies that attack your body’s tissues and/or organs. With Hashimoto’s thyroiditis, antibodies attack the thyroid and keep it from producing enough hormones.

The thyroid is a small gland located below the skin and muscles at the front of the neck, just at the spot where a bow tie would rest. It’s brownish red, with left and right halves (called lobes) that look like a butterfly’s wings. It’s light like a butterfly, too, and usually weighs less than an ounce.

Mayo Clinic – Treatments and drugs

Standard treatment for hypothyroidism involves daily use of the synthetic thyroid hormone levothyroxine (Levothroid, Synthroid, others). This oral medication restores adequate hormone levels, shifting your body back into normal gear.
