Can someone go from HYPOthyroid to HYPERthyroid?!
Question: Can someone go from HYPOthyroid to HYPERthyroid.?
Long story short, 10 months after my son was born i was diagnosed with HYPO-thyroidism. My TSH was 38.31 and so i was put on Thyroxine 100mcg daily. Then 3 weeks after that i had another blood test and that showed a TSH of 4.80 and then 3 weeks after that i had my final test to determine the levels (that would be 6 weeks in total after starting the meds) and my TSH now is 1.78.....So, how does one know that it is not going to get lower and lower and lower.? The Dr. did not mention anything about having to come back for tests etc...just to keep on taking the meds as usual. Any info on the matter would be greatly appreciated. THANKS! ;)Health Question & Answer

Hi, the answer to your question is Yes, one can go from hyPO to hyPER but this is a condition called thyroiditis.
In relation to you, it definitely doesn't sound like you have thyroiditis. Your TSH is suppose to go lower while on meds. This is called negative feedback. It does not mean you are hyperthyroid unless your symptoms show so. A lot of people and doctors feel that in order to rid people of their symptoms the TSH must be below 1 and sometimes even to a point of non-detection. This has been shown without a doubt to be completely safe. Don't worry about the blood tests, worry about the symptoms. Study the symptoms of hyperthyroidism and watch out for them.
If your symptoms remain the same after being on a higher dose of thyroxine for a while, find a doc that will switch you to Armour (desiccated thyroid extract - T3 and T4) or T3 (Cytomel/Tertroxin).
Sometimes one can experience hyper symptoms even on a low dose when they are not tolerating thyroid medication and this is due to low adrenal output. These people must be put on cortisone for a while till they can tolerate higher doses.Health Question & Answer

A normal TSH is 0.4 to 6 so your initial lab value was high. (hypothyroid). It came back into a normal range with the medication. It could go to the other extreme, but is not likely. Your physician will continue to monitor your progress with regular blood tests. You didn't say what your other thyroid values were like the T3 or T4, but I'm sure your doctor will be watching them also.Health Question & Answer
