There are some medications and supplements that will elevate TSH, but unless you are taking one, it is likely that you have been developing hypothyroidism (although there a couple of other causes of TSH, such as pituitary adenomas). I would get the thyroid panel, and make sure you do get tested for antibodies: thyroid peroxidase (TPO) and antithyroglobulin antibodies (TG Ab).
