If you are taking thyroid medication, there are certain things that can affect how your medication gets absorbed by your body; which could affect the outcome of your blood test. Prescribed thyroid medication will state on the bottle the proper way to take it. Typically it will say on the bottle to take one tablet in the morning, on an empty stomach, with plenty of water. It is important to take it with water, and on an empty stomach, because it will allow the thyroid medication to be absorbed into the bloodstream. It is best to wait at least 30 minutes before eating food. If you eat immediately after taking your thyroid medication, drink coffee, drink alcohol, or even add Metamusil to your water, this can affect the overall effectiveness of your thyroid medication.
Talk with your doctor if you have any questions or concerns about your diet, and how it might affect the outcome of your thyroid blood test.
