Hyperthyroid Test Results

My daughter just got test results & something seems wrong with the measures. TSH shows 63.180 on test 0.450-4.500. seem like 2 different test measurements are being combined.

too Much Synthoid

I was having chest pains and could no longer walk up the stairs. I basically was becoming handicapped and severe chest pains. Dr kept raising my synthroid. I finally googled "too much synthroid" and my symptoms appeared on the page . I then cut my synthroid pills myself until I felt better. I have come to realize I feel wonderful at around 1.5-3.0.My chest pains went away and I feel great. Synthroid must affect people differently. My new endo keeps me exactlly where I tell her I need to be to feel good. Is this common? Are others having such severe chest pains below 1.2? I feel like I had to heal myself and that I was just lucky to figure it out. I too was diagnosed Hasimotos.

Have Hope and Keep Fighting

I was diagnosed with hypothyroidism (hashimoto’s) after a bout of glandular fever/mono in 2008. My TSH at the time was 5.6 and I had elevated thyroid antibodies. I didn’t feel well (all the usual symptoms plus a lump feeling in the throat) but I didn’t go on medication by choice as I wanted to see whether I would feel better after recovering from the glandular fever. It worked. Because it was hashimoto’s thyroiditis, my thyroid levels did return to normal without medicine and then they even swung into a slightly hyperthyroid state (though I didn’t notice as I didn’t feel any hyperthyroid symptoms). Three year’s later, in early 2011, my symptoms returned with full force and they didn’t go away. I am 31 years old and female. I had been monitoring my thyroid levels with regular blood tests over this time in case this happened. I went to my doctor feeling terrible and got tested again. My TSH was considered to be in the normal range - my lab says this is .40 - 4.50 (my TSH from m

I Just Got My Thyroid Tested

I am really worried about my report for TSH which is 5.52 and the given range is 0.47-5.01 for adult and 0.70-5.70 for children.I have every possible symptoms as far I had understood. I am 18yrs old! I do have a family history of thyroid condition, my mom and my grandmom have it. It's really affecting my life. My free T4is 1.18.

Currently a Patient & Work in Healthcare

I have been suffering for 5yrs with feeling my hormones are out of wack an until recently I had my TSH numbers show above 5.0

Numbers

How about doctors examining and questioning the patient instead of just looking at lab numbers? There are other health issues that impact the TSH score: autoimmune diseases, inflamed hypothalamus polyglandular disorder, etc. It is dangerous to treat the patient as if the TSH or thyroid lab test number is the whole thing. How is the patient functioning?

TSH Normal for Lab

My lab used .34 to 4.82 as normal. This was as of July 13, 2011. I assume over time, the lab may change their "normal" range.

TSH Level at .20

I had a thyroidectomy in May of this year - 2011 and was placed on Synthorid 112 mcg. Recently had a follow-up TSH level reading and result came back at .02. My Endo says this is TOO high and has reduced my Synthorid level to 100 mcg. I have severe pain in my joints, have low energy and get exhausted after a 20 mile bike ride which I used to do without any issues. Now if the new referenced range is 0.0 to 3.0 or even the old referenced range of .5 to 5.0 range, why would he say my TSH level is TOO high?! This makes no sense to me and I'm now seeking a second opinion. This is so frustrating to say the least. I have come to the conclusion that Doctors are nothing but practioners - trial and error is what that translates to - and not an authority regards of the fact that they have a PHD. PHD just translates to "Push Here Dummy"...

LowTSH W/Perfect T3/T4 Numbers

I have had Hashimotos for 23 years and been takiing Armour for 11 years. During that time my TSH remained low but had no signs at all of Hyperthyroid and I felt good, T3/T4 levels between low to mid range. I now have a new doctor and my TSH is .006 as in the range it has been since going on the Armour and he cut 1/3 of my Armour dose that I had been taking for 11 years. I now feel terrible like when first diagnosed with Hashimotos. I read that Hashimotos is when your body attacks your thyroid gland and eventually destroys it. I am wondering if it is possible that my gland is not producing at all, thus the TSH readings. I just turned 70 this year and feel terrible on the lower dose. My body went into a tailspin. I checked all my labtests over last 11 years and the first one 11 years ago was 3.36 but my T3/T4 were both over the high range. Next year it dropped to 1.7 and levels were still over high range. Since then, they have remained in the .006 range and all vitals are excellent.

So Frustrated

I am 21 years old I have always been really skinny until after I got pregnant, I also had preclamsia and after the birth all I lost was water weight. I went to the dr for a check up they said my thyroid was enlarged and wanted me to get test done. My child is a year old and I am still very big. It's taking a toll on my body which is very small made. The test came back barely out of range, what I was told and they will not do anything about it. It's nothing, so I'm wondering if it is nothing why am I still 45 lbs overweight and can not lose the weight? I exercise several times a week and haven't lost a lb since my baby was about 3 mths old. I do gain a few lbs and lose it again but I pretty much stay the same weight. I have done everything! My hair and nails are brittle and break off my voice goes in and out I have no energy my knees are becoming a problem I have headaches and bowel problems daily.

Thyroid Problems

I have struggled for years to obtain the normal range with my thyroid gland and my doctor has increased the level of medication accordingly. I still maintain the level of 5.98 with all the effects still occuring. I am now in my mid sixties and still having hot flashes etc. The thyroid has been scanned and measured with the left hand side being significantley larger than the left. Surely by now there should be some homeopathic treatments for this condition? I find excercise is quite helpful with the symtoms.

I am 17 years old and told that I have hypothyroidism, and my level is 13. My mom told me that the normal levels are like 2 or 3 area.

Compunet

Compunet labs here in Ohio are using the outdated range and my docs accept the range. My TSH has been over 3 for a few years, but because they all accept the old levels "nothing is wrong with me". Yet I have almost every symptom and other illnesses that are linked to hypothyroid.
—Guest ss82

New Range

I was lucky to find a doctor that understood that if I felt "okay" at TSH of 1.0 that I could feel better even lower. Be persistant in your health care. If you don't feel good at 2.0 or so, find a new doctor that understands.
