Flashcards
Hypothyroidism
Hypothyroidism
A condition where the thyroid gland doesn't produce enough thyroid hormones, slowing down body functions.
Thyroidectomy
Thyroidectomy
Surgical removal of all or part of the thyroid gland, often due to cancer or other thyroid conditions.
Hyperthyroidism
Hyperthyroidism
A condition where the thyroid gland produces too much thyroid hormone, speeding up body functions.

Study Notes
- The thyroid gland, located at the base of the neck below the Adam's apple, produces the metabolic hormones T3 and thyroxine (T4).
- Proper thyroid function results in a normal metabolic rate.
- Over or underproduction of thyroid hormones can lead to energy fluctuations, sleep disruption, temperature intolerance, and weight control issues.
Goiter
- Iodine is essential for the thyroid to produce T3 and T4 hormones.
- Iodine deficiency can cause a goiter, an enlargement of the thyroid gland.
- The term 'goiter' comes from Latin, referring to the throat.
- Goiters were once prevalent in the iodine-deficient soil of the American Midwest, known as "The Goiter Belt," where access to iodine-rich seafood was limited.
- Iodized salt has made goiters due to iodine deficiency uncommon in modern America, but they persist in other regions worldwide
Hypothyroidism
- Hypothyroidism is a condition resulting from insufficient thyroid hormone production.
- The prefix 'hypo' means 'less than normal,' indicating the thyroid produces less-than-normal hormone amounts.
- Hypothyroidism symptoms include energy loss, increased sleep needs, cold intolerance, slow pulse, constipation, weight gain, and depression.
- Factors causing underproduction of thyroid hormones include disease, radiation therapy, certain medications, or thyroid surgery.
- A thyroidectomy is the surgical removal of all or part of the thyroid gland, often needed in cases of thyroid cancer.
- Untreated individuals who have undergone a thyroidectomy may require synthetic thyroid hormone medication to prevent hypothyroidism.
Hyperthyroidism
- Hyperthyroidism is a condition where the thyroid gland produces excessive thyroid hormone.
- The prefix 'hyper' means 'more than normal'.
- Hyperthyroidism symptoms include heightened energy, decreased sleep needs, heat intolerance, rapid pulse, frequent bowel movements, weight loss, nervousness, agitated behavior, and an inability to relax.
Graves’ Disease
- Graves' disease is an autoimmune disorder that leads to hyperthyroidism.
- In autoimmune disorders, the immune system mistakenly attacks its own tissues.
- Graves' disease shares the typical hyperthyroidism symptoms.
- Exophthalmos, a bulging of the eyeballs, is a distinguishing symptom that can develop.
