Thyroid Disorders; Key Q&A.
What is thyroiditis Thyroiditis Definition
Thyroiditis is inflammation of the thyroid gland, a butterfly-shaped organ next to the windpipe.
The thyroid is the largest gland in the neck. ?
Thyroiditis is an inflammation of the thyroid gland. It can result in a nodule nodule: see concretion.
In geology, a rounded mineral concretion that is distinct from, and may be separated from, the formation in which it occurs. , or it can cause hypothyroidism hypothyroidism: see thyroid gland. , hyperthyroidism hyperthyroidism: see thyroid gland. or both (one followed by the other).
What role does the thyroid play in the body?
The thyroid gland makes, stores and releases thyroid hormone (TH), which is known as the body's metabolic hormone. TH tells the body how fast to use energy. If there is too much TH in your blood, you become hyperthyroid Hyperthyroid
Having too much thyroxin stimulation.
Mentioned in: Goiter , and you use energy too fast. If there is too little TH in your blood, you become hypothyroid Hypothyroid
Having too little thyroxin stimulation.
Mentioned in: Goiter
hypothyroid adjective Referring to hypothyroidism, see there , and you use energy too slowly.
What causes hypothyroidism?
The most common cause of hypothyroidism in the United States is an autoimmune disease known as Hashimoto's thyroiditis. Hypothyroidism also can occur spontaneously; can develop during or after pregnancy; can be present at birth; or can develop after hyperthyroid treatment.
What is the cause of hyperthyroidism?
The most common cause of hyperthyroidism is an autoimmune disease known as Graves' disease. It can also be the result of nodules (lumps in the gland) that cause an overproduction o·ver·pro·duce
tr.v. o·ver·pro·duced, o·ver·pro·duc·ing, o·ver·pro·duc·es
To produce in excess of need or demand.
o of TH. Hyperthyroidism also can develop during or after pregnancy.
Is Graves' disease curable?
Graves' disease is not curable, but it is rarely fatal and is a completely treatable disease. Remission may be permanent, but the thyroid should be checked periodically to be sure. Severe stress can aggravate a recurrence.
What causes postpartum thyroiditis?
The cause of postpartum thyroiditis is not known, but it is believed to be an autoimmune disease similar to Hashimoto's thyroiditis. As with Hashimoto's, postpartum thyroiditis is associated with the development of anti-thyroid antibodies.
What if I need treatment for hypothyroidism or hyperthyroidism while I'm pregnant?
Pregnant women are at an increased risk of developing thyroid dysfunction as compared to the general population. Any woman with a prior history of a thyroid problem, a family history of thyroid disease or symptoms of thyroid dysfunction should be tested for thyroid dysfunction as soon as she knows she is pregnant. TH (T4) is absolutely safe to take during pregnancy and is essential for the health of the fetus if you are diagnosed with hypothyroidism. If you are diagnosed with hyperthyroidism, beta blockers and antithyroid drugs are used. If a woman is allergic to these drugs, surgery may also be considered. Radioactive iodine is not an option because it will pass into the fetus and damage its thyroid gland.
Is there a relationship between thyroid disorders and osteoporosis?
Untreated hyperthyroidism can increase your risk for osteoporosis. Bones generally renew themselves in a process called bone turnover or resorption resorption /re·sorp·tion/ (re-sorp´shun)
1. the lysis and assimilation of a substance, as of bone.
n. . Because hyperthyroidism increases the body's metabolism, bone turnover also is increased. This increase causes old bone tissue to dissolve before new tissue is fully formed, which does not give the body enough time to produce enough minerals for the new bones. The result: thin or weakened bones--osteoporosis.
Do some people have both hyperthyroidism and hypothyroidism?
The use of thyroid hormone or antithyroid drug treatment can, over time, produce the opposite effect, especially if the dose of medication given is too high. This means that if you are taking antithyroid medication for hyperthyroidism, you could become hypothyroid; if you are taking thyroid hormone medication for hypothyroidism, you could become hyperthyroid. Pay close attention to how you feel and be aware of the symptoms for each type of thyroid disorder.
Do chest and dental x-rays place me at a higher risk for thyroid cancer?
X-rays used today to take images of the head and chest are not harmful. However, radiation procedures from the 1920s to the 1960s for inflamed tonsils, adenoids, lymph nodes or an enlarged thymus gland could put you at risk. There is a clearly established relationship between thyroid cancer and these early radiation treatments of the head and neck. If you believe you were exposed to this type of treatment as a child or an adult, you should have your thyroid checked annually.
Can taking your morning basal body temperature accurately predict a thyroid disorder?
No. Some people have normally high or low waking body temperatures. The only way to accurately diagnose a thyroid disorder is with a highly sensitive TSH TSH thyroid-stimulating hormone; see thyrotropin.
Thyroid-stimulating hormone (TSH) blood test.
