TSH (Thyroid Stimulating Hormone)

Measuring the level of TSH can be very helpful in terms of determining if the problem resides with the thyroid itself or the pituitary gland. If TSH levels are high, then it's merely the thyroid gland not responding for some reason but if TSH levels are low, it's the hypothalamus or pituitary gland that has something wrong with it. The problem could be a tumor, some type of trauma, or an infarction.

Drugs that can increase levels of TSH include lithium, potassium iodide and TSH itself. Drugs that may decrease TSH are aspirin, heparin, dopamine, T3, etc. Increased TSH is indicative of thyroiditis, hypothyroidism, and congenital cretinism. Decreased levels are indicative of hypothyroidism (pituitary dysfunction), hyperthyroidism, and pituitary hypofunction.

Normal ranges:

2-10 uU/ml or 2-10 mU/L

Knowing how to interpret these tests can be a very valuable tool in terms of health and your body building and athletic progress. Use your new knowledge wisely!

See bolded word....so does this mean that a dose of asprin could negatively effect TSH levels and eventually affect weight? What about free test levels? I say this becauses since low levels of TSH could effect pituitary production which produces LH..the main factor in testosterone porduction.

This could affect peopl that constantly take painkillers for injection pains...it could possibly be hurting them

Any comments welcome
