Thank you for the additional information.
The most common cause of thyroid disease is an autoimmune
inflammation of the thyroid. One of the patterns of manifestations of thyroid disease is that when the inflammation first starts, the person will be hyperthyroid, as hormone is pushed out of the thyroid, and then later evolves into hypothyroidism
, as the gland has no more reserved hormone and is unable to manufacture sufficient hormone to keep up with demand.
The treatment that would be recommended would be based upon the most recent lab test results.
The symptoms that you describe are common symptoms with hypothyroidism, although some people can have paradoxical symptoms. They will usually resolve with proper treatment, but she has to be willing to take the medicines that would be involved in treatment.
If the symptoms are not as bothersome to her and the blood tests are only mildly abnormal or borderline, then it would be OK to not undergo treatment. But if the symptoms are more bothersome and it is desired to get rid of the symptoms, then the next step would be to take medicines as guided by the most recent blood test results.
Since it is ultimately her decision of whether to take medicine, the most that you can do is encourage her to begin treatment so that she will feel better.
If I can provide any further information, please let me know.
