Were you looking for information on Hypothyroidism? Hypothyrodism is a common misspelling of hypothyroidism.
Hypothyroidism, which is characterized by low levels of thyroid hormones -- in particular, TSH and T4 -- can be caused by medical conditions, radiation therapy, injury, or surgery. If it is caused by damage to the thyroid gland itself, it is known as primary hypothyroidism. If the pituitary gland is affected, it is called secondary hypothyroidism. Tertiary hypothyroidism is diagnosed when the hypothalamus is involved.
Thyroid hormones play several different roles in the body, but generally affect a person's metabolism. Thus, possible symptoms of low thyroid levels include weight gain, a puffy face, fatigue, and decreased or irregular menstrual periods. Several other symptoms, however, are also possible.
