Hello and welcome – There are several scenarios where Graves’ patients can go hypo on anti-thyroid drugs. Being on too high of a dose of anti-thyroid drugs like Methimazole can push patients into hypo territory. In other cases, the antibodies that cause Graves’ can start *blocking* thyroid hormone production instead of stimulating too much thyroid hormone production. Finally, there are some patients that actually have both Graves’ disease and Hashimoto’s thyroiditis – Hashi’s is another autoimmune condition that causes destruction of the thyroid gland and can lead to hypothyroidism.
Each patient is different, but other hypo symptoms can include fatigue, joint pain, unexplained weight gain, dry skin, cold intolerance, heavier periods, and slow pulse.
Even though you had labs a couple of months ago, if this continues, it’s definitely worth contacting your doctor to schedule an appointment and get some further insight on what is going on. Of course, it could just be a temporary episode due to dehydration or diet changes, but this is certainly worth keeping an eye on.
Take care!
