Hello,
Sorry lots of questions again but could use a little help. Have been on several different doses of Synthroid for 4 1/2 years. I seem to do ok for awhile then start to experience panic attacks, anxiety, hot flashes, palpations, shakes, tired but can't sleep, and a mind that goes a mile a minute then I go thru periods of being tired, cold, body aches, digestive problems, headaches, slow brain, gain weight easy,
At times Synthorid dose is adjusted but there have been MANY times I am told labs are normal it's just anxiety,depression ect.
Recent labs
Feb 2011 Synthroid 650mcg weekly
TSH .37 (0.34-4.82)
June 2011 Synthroid Alternating 600mcg & 625mcg weekly
TSH 3.16 (0.34-4.82) FT4 0.9 (0.6 - 1.9)
Oct 2011 Synthroid 525mcg weekly
TSH 17.60 (0.35-4.94) FT4 .94 (0.70 -1.48) FT3 1.76 (1.71 -3.71)
Thyroglobulin Antibodies 83 (<20)
Why would my TSH be high and my FT4 & FT3 normal??
My new Dr wants me to try 60 Armour and I am afraid to take this since it contains T3 and I am already so anxious.
Is 60 of Armor the same as .75mcg of Synthorid?
I just don't know what to do any more any advice would be greatly appreciated.
Thank you
Sometimes with Hashi's you can swing between Hypo and Hyper. And your symptoms would indicate that is what is happening to you.
"normal" ranges are FAR to broad and most people to stay symptom free seem to need to be stabilized and keep their FT4 mid range. AND keep their FT3 in the upper 1/3 of the range. Your last labs show you to be on the lower end of both and I would suspect that you are feeling Hypo.
You mention that you are taking Synthroid in "weekly" amounts. I have never heard of people taking this once per week. Or are you taking it daily and your only listing the total?
T3 medication the rule of thumb is that it is 4 times more effective than a T4 med. because T4 has to be converted into T3 whereas if you directly take a T3 med it is available immediately. Therefore for each 5 mcg of T3 med you take, your T4 med should be reduced by 20 mcg. HOWEVER. If you are already low on FT4 9Which you are) you may not need any reduction.
Now you also have to take into account that you seem to be swinging between Hypo and Hyper. Have you had a ultrasound of your Thyroid to look for nodules. Some of the nodules are known to "leak out" thyroid erratically or randomly from time to time. This can sometimes explain why you will be Hypo and then suddenly swing to Hyper. You may want to ask your Dr. about nodules and possibly getting an ultrasound done.
You may also want to be tested fro Graves disease. This is done with a TSI test. Some people have both Hasimoto's and Graves.
