My Thyroid Doctor says my known underactive thyroid is fine due to my TSH test. In fact it shows it as showing a bit high so she changed my prescription from 137 to 88 6 mths ago. My retired Doctor always had me on 137 and I was fine. Now I experiencing constipation and all the signs of underactive thyroid again, although she feels it is still high my TSH3 was .025 Total thyroid T4 was 88. I really do not feel myself and feel I am going back the other way again the way I was 13 years ago. I also have had a hard time with maintaining my weight as well. I really do not feel at all that I am overactive how can she say the test shows such a thing when I have all the systems of a underactive thyroid
