My blood tsh was 15 which is out of range. Does that mean it is high or low?

Hello. 15 is way too high and is heading towards the danger zone. You must not be feeling too well. In order to lower this you require more medication to lower this down to a better range. The current range is .3 to 3.0. Within that range you will be healthy and have few problems.

A lot of things can raise your TSH. Not taking your medication at the same time each day, taking calcium too close to the medication, too much magnesium. Trauma, illness, high fevers, will change your metabolism and your body will want more medication to balance the metabolism.

Be sure to take your synthroid first thing in the morning with a full glass of water only. No juice, coffee or food until half an hour after you take it. Calcium and vitamins which you need to take daily, is four hours later. So any time after lunch is a good way to remember.

Working with an endocrinologist can help you as well. It does take about six weeks to see a change. And if that is not right, you will need another adjustment. Let me know if you need more information. Hope you are well soon. Karen

You are way high. It means you're not producing enough thyroid hormone
