What are Hypothyroidism and Hyperthyroidism?
What is Hypothyroidism?
Hypothyroidism is a condition in which the thyroid is not making enough thyroid hormone. This can lead to feelings of fatigue and weakness. If it goes untreated, it can raise cholesterol and increase the risk of heart attack or stroke. Hashimoto’s thyroiditis is one cause of hypothyroidism. The immune system attacks the thyroid and then the body cannot make its own thyroid hormone. While there may be no symptoms early on, untreated hypothyroidism can lead to:
Symptoms of Hypothyroidism
- Dry skin and brittle nails
- Feeling tired or weak
- Increased sensitivity to cold
- Heavy or irregular menstrual periods
- Joint pain
- Memory problems or having trouble thinking clearly
What is Hyperthyroidism?
Hyperthyroidism is a condition in which the thyroid makes too much thyroid hormone. Graves’ disease is a common cause of hyperthyroidism and it occurs because the body’s immune system is incorrectly attacking the thyroid gland. When the thyroid fights back, it produces extra thyroid hormone. Sometimes increased thyroid hormone can be caused by swollen thyroid or small growths called thyroid nodules. There may be no symptoms at all or hyperthyroidism can cause the following symptoms:
Symptoms of Hyperthyroidism
- Nervous, moody, weak, or tired
- Hands may shake; heart may beat fast or breathing problems
- Sensation of being hot and sweaty or having warm, red, itchy skin
- Increased bowel movements
- Fine, thin hair and hair loss
- Weight loss without change in eating patterns
- Difficulty concentrating
- Sleep problems or restlessness
- Goiter or thyroid nodules
- Irregular menstrual periods in women
Improving thyroid function can help prevent depression, diabetes, obesity, and heart disease. Both men and women need healthy thyroid function for optimal sexual and reproductive health. Thyroid hormone is also important in lipid metabolism.
What Does the Complete Thyroid Profile Test For?
- T4, Total – T4 (thyroxine) is a hormone produced by the thyroid gland. This test measures the amount of T4 in your blood.
- T4, Free – Most of the T4 in your body binds to protein, the T4 that does not is called T4 and circulates unbound in your blood. This test measures these T4 hormones.
- T3, Total – T3 (triiodothyronine) is a thyroid hormone and is important for the body’s control of metabolism. This test measures the amount of T3 in your blood.
- T3, Free – Most of the T3 in your body binds to protein, the T3 that does not is called T3 and circulates unbound in your blood. This test measures these T3 hormones.
- T3, Reverse – Reverse T3 is converted by the liver from the stored hormone T4, it is the body’s way of getting rid of unneeded T4 every day. Sometimes the body can make too much reverse T3 from a number of causes including chronic emotional, physical, or biological stress, chronic sickness, after surgery, diabetes, aging, or an acute injury. This test measures for levels of reverse T3.
- Thyroid Stimulating Hormone (TSH) – TSH causes the thyroid gland to make two hormones, T3 and T4, which help control your body’s metabolism. This test is done to find out whether the thyroid gland is working properly.
- Thyroglobulin Antibody – Thyroglobulin is a protein produced and used by the thyroid gland to make the hormones T3 and T4. Antibodies are the proteins made by the immune system to fight toxins, bacteria, and viruses. High levels of antibodies suggest the immune system is mistakenly attacking the thyroid gland. This test measures the blood levels of antibodies the body has made against the compound thyroglobulin.
- Thyroid Peroxidase Antibody – Thyroid peroxidase (TPO) is an enzyme made in the thyroid gland and is important in producing the thyroid hormone. TPO converts to thyroid hormone T4 to T3. High levels of antibodies suggest the immune system is mistakenly attacking the thyroid gland. This test measures the level of antibody the body has made against thyroid peroxidase.
What Should I do Before I Take This Test?
- Inform your practitioner of all medications and supplements you are currently taking.
- Arrange serum collection for Monday-Thursday.
- See instructions inside test kit for blood draw.
How are Thyroid Hormone Imbalances Treated?
Doctors may prescribe thyroid supplementation, nutrients to support the thyroid gland, and/or dietary and lifestyle changes.
