Strangely, the higher the TSH, the more hypothyroid someone is. If your thyroid is the cause of your problems, your TSH is likely on the high end of "normal."
Thyroid stimulating hormone (TSH) is the hormone that tells your thyroid to get moving (it "stimulates" it), so when your thyroid is sluggish, your body produces more TSH. It's confusing because we thinking hypo = low, which it does, but that means a higher TSH.
The human body is a crazy thing!
