How Do You Use Thyroid Tests To Detect Anorexia?
Three glands located in the head and neck area all work together to control metabolism, among other functions. The hypothalamus, the pituitary and the thyroid secrete complementary hormones that keep the body burning its fuel at the proper rate. Malnutrition and low body weight caused by anorexia can cause damage to the thyroid, which is signaled by high THS (Thyroid Stimulating Hormone). A doctor performing tests to detect anorexia will use thyroid tests to help confirm the diagnosis. Tell your doctor if you have had any tests done within the last 6 weeks, including scans and X-rays, that involved a radioactive or iodine trace. Ask your doctor which tests he is requesting and what they measure. Some thyroid tests measure TSH, produced by the pituitary, and others measure T3 and T4, produced by the thyroid. Other common tests include a blood count (CBC) for anemia, malnutrition and lack of red or white blood cells. These tests may also reveal a cause for weight loss other than anorexia
