Thyroid Levels

Thyroid Guide – Thyroid Levels: The thyroid gland produces thyroid hormones and is responsible for the metabolism in the body. When the thyroid gland produces too much thyroid hormone, one may suffer from hyperthyroidism. When the thyroid glands fail to produce enough thyroid hormones needed by the body, one may suffer from hypothyroidism. One may complain about feeling symptoms such as losing or gaining weight, depression, cold or heat intolerance and increased or decreased heart rate. When this happens it would be best to seek medical help. To be able to assess and determine which thyroid disorder an individual may be suffering from, one must submit himself for a thyroid test.

Testing Thyroid Levels

The thyroid test is dome by getting a blood sample of a person suspected of having thyroid disorder. This blood sample will then be forwarded to the laboratory. The thyroid test is done to check on an individual’s thyroid function. Once the thyroid test result is available, the attending physician will then be able to check and assess an individual’s thyroid hormone level.

There are three levels of thyroid hormone levels in the body. These are high thyroid hormones level, low thyroid hormone level and normal thyroid hormone level. Low thyroid hormone level means that a person has hyperthyroidism or an overactive thyroid gland. High thyroid hormone level indicates that an individual is suffering from hypothyroidism or an underactive thyroid gland. Thyroid test results that show a normal thyroid hormone level indicates that an individual’s thyroid gland is producing just enough thyroid hormones needed by the body.

Anti-Thyroid Drugs

What do antithyroid drugs do?

Antithyroid drugs block pathways leading to thyroid hormone production.

Antithyroid drugs used in this country are Propylthiouracil (PTU) and Tapazole®. Some physicians will recommend antithyroid medication as a first line of treatment to see if the patient is one of the lucky 30% of patients who go into a remission after taking antithyroid medication for one to two years. (Patients are said to be in remission if their hyperthyroidism does not recur after discontinuing the antithyroid drugs.) If antithyroid drugs do not work for the patient, then physicians usually recommend radioactive iodine.

Antithyroid drugs are also used to treat very young children, older patients with heart conditions, and pregnant women. For severe or complicated cases of hyperthyroidism, especially in older patients, PTU or Tapazole® can be given for four to six weeks to bring the hyperthyroidism under better control prior to administering radioactive iodine treatment.

In cases when women are diagnosed with Graves’ disease while they are pregnant, PTU is prescribed. The smallest dose possible is given because the medication does cross over to the fetus. The mother should be checked every three to four weeks during the pregnancy so that the lowest possible dose can be given. Too much PTU can cause fetal goiter, hypothyroidism, and mental retardation.

Are there any side effects?

Antithyroid drugs cause side effects in about 10% of patients. Reactions can include:

  • skin rash
  • swollen, stiff, painful joints
  • sore throat and fever
  • low white blood count, which can lead to serious infections
  • jaundice (yellow coloring of the skin) and, rarely, liver failure.

Most side effects clear up once the drugs are stopped. If you think you are having a reaction to anti-thyroid drugs, call your doctor immediately.

What can be expected with antithyroid drug treatment?

  • Several pills are taken from one to four times a day, every day for six to 24 months.
  • Some patients complain that the pills have an unpleasant smell and taste.
  • There is usually some symptom relief within one to two weeks. In some cases, it can take several months to relieve symptoms.
  • Antithyroid drugs have a relatively low success rate. While PTU or Tapazole® may correct the problem temporarily or for a few years, the chances of a permanent remission are about 30% once the drugs are stopped.
  • The likelihood of achieving a permanent remission is increased if the patient takes the medication for one to two years.
  • There are side effects in 10% of the people treated with Tapazole® or PTU. These are:
    • skin rash over most of the body swollen, stiff, painful joints
    • sore throat and fever — if this happens, the antithyroid drugs should be stopped immediately and the physician contacted
    • jaundice
    • liver damage, which is fatal in rare cases
  • Because antithyroid drugs pass into breast milk, only PTU in a dosage less than 200 mg a day is advised if the baby is not weaned.
  • Within 15 years, the thyroid gland may burn out, resulting in hypothyroidism, and the patient will need thyroid hormone replacement.
Can Depression Be Caused By Thyroid Disease?

Most patients with hypothyroidism have some degree of associated depression, ranging from mild to severe. 10% – 15% of the patients with a diagnosis of depression may have thyroid hormone deficiency. Patients with depression should be tested to determine if they have a thyroid disorder.

  • Several research studies have been done and continue to be done on the association between depression and thyroid disease. Although all forms of depression, including bipolar disorders like manic depression, can be found in either hypothyroidism or hyperthyroidism, depression is more often associated with hypothyroidism. Many patients with hypothyroidism have some degree of associated depression, ranging from mild to severe.
  • If a large population of depressed patients was screened, a significant percentage, perhaps 10% – 15%, would be found to have thyroid hormone deficiency. For this reason, patients with a diagnosis of depression should be tested to determine if they have too little thyroid hormone. If they do, thyroid medication should be prescribed.
  • Thyroid hormone is sometimes prescribed for depressed patients with normal thyroid function because it magnifies the beneficial effects of certain antidepressants.
  • Lithium, a commonly prescribed drug for certain types of depression, has profound effects on the size and function of the thyroid gland. Patients taking lithium need periodic examinations of their thyroid gland and thyroid function.
What is Graves’ Disease?

Graves’ disease is the most common form of hyperthyroidism. It affects many Americans, including Olympic athlete Gail Devers, who won a gold medal in track after being diagnosed with and treated for Graves’ disease.

Graves’ disease is caused by problems with the immune system. Normally, the immune system defends the body against germs and viruses. In autoimmune diseases such as Graves’, the immune system attacks the body’s own tissues. In Graves’ disease, the body produces antibodies which make the thyroid gland produce too much thyroid hormone.

Diseases of the immune system tend to run in families and are about five times more common in women. Graves’ is linked to other autoimmune conditions, such as Hashimoto’s thyroiditis, premature gray hair, diabetes mellitus, arthritis and patchy loss of skin pigment (vitiligo).

3 Thyroid Levels

With thyroid tests, an attending physician will be able to determine if one’s thyroid gland is dysfunctional and which thyroid disorder an individual may be suffering from. The thyroid test plays a very important role in determining a thyroid disorder since the attending physician’s diagnosis is based on the thyroid test result. The thyroid test does not only check the thyroid gland functions, it also checks if the body is able to receive enough thyroid hormones from the thyroid gland.

There are three types of thyroid hormone levels. A thyroid test result may show a low thyroid hormone level in the body. Having a low level of thyroid hormones in the body shows a clear basis of hyperthyroidism or an overactive thyroid gland. The thyroid gland produces too much thyroid hormone, more than the body needs. An individual may have symptoms such as weight loss, palpitations, heat intolerance and increased heart rate. Other thyroid test result is a high thyroid hormone level.

When one has a high level thyroid hormone, this is enough basis to determine that an individual is suffering from hypothyroidism or an underactive thyroid gland. In this case, the thyroid gland fails to produce enough thyroid hormones needed by the body. One may feel symptoms such as fatigue, decreased heart rate, depression, constipation and dry skin.

Another thyroid test would show a normal thyroid hormone level. In this case, an individual has nothing to worry about since the thyroid gland produces and secretes just enough thyroid hormones needed by the body. In cases that an individual may have either a high thyroid hormone level or a low thyroid hormone level, the attending physician will provide a proper treatment and medication depending on the extent of the thyroid disorder.
