You should insist on FT3 and FT4 EVERY time you have labs. TSH is simply not sufficient to base meds decisions on. Year old FT3 and FT4 are virtually ancient history once you're on thyroid meds, but yours of a year ago are both low, indicating an increase in meds was in order.
Although hypo is typically associated with intolerance to cold, "I" (take that for what it's worth!) think that it often manifests as a narrowed range of heat/colt intolerance. We can be intolerant to both heat and cold.
My first reaction to this is that it has to do with not having hormones "on demand" any more. Out bodies don't react quite as quickly to changes. We run our hormones at an acceptable level, but we don't have the give and take that we might have had before. When you're dealing with something like temperature change, which can happen very rapidly with climate control, we don't react as fast as we might.
If your balance of FT3 to FT4 is off, you can experience some odd symptoms. Treating a thyroid condition without testing FT3 (especially if on T3 meds) and FT4 really borders on medical negligence.
However, another possibility is a problem with the hypothalamus. The hypothalmus is responsible for body stasis...regulating temp and regulating thyroid hormones, among many other things. So, it may not be the thyroid messing with anything, but the hypothalmus mess with more than one thing.
Please post your actual thyroid test results with reference ranges. If you still have all those symptoms, then your levels are NOT "fine". If you still have symptoms, your meds need to be either adjusted or changed.
What meds are you on?
TSH i ref. range [.34-4.82] Mine is .72. I have changed meds a few times and I am currently on Armour 60 mg. I know I am on the low end of "level" and I have been each time. Armour does seem to work better for me. I did not have my free T4 and free T3 tested in my last test but I have in the past. The above test is a few months old. The test with the free T4 and T3 was done a year ago and here are the results for it. TSH i Ref range [.34-4.82] mine 1.89 FT4 ref. range [.76-1.46] mine 0.95 FT3 Ref range [2.18-3.89] mine 2.83.
I have tried to get into one of the few good endo. drs that actually treat the symptoms not just the thyroid none are currently taking new patients nor have they in the year and a half I have tried to get into them. My gp is the one treating my thyroid and says that since I am within the range the symptoms I have are due to something else and basically fluff it off and will increase my dosage. I am hoping to go to a naturopathic physician soon as I have found one locally and am sick of feeling like crap.
Also from what I have read on here and the people I have talked to it is a all to common occurrence for drs to only treat the thyroid and ignore the symptoms.
What I was really wondering since I can't seem to find it anywhere is, if it is true that your core temp will go up like mine did above due to your thyroid and why can't your body deal with hot temps like that? What is the thyroid messing with that causes it?
Thanks for any info! Best wishes,Sissie
My body temperature can be up to 37.5 C (99.5 F) when over-medicating with thyroxine, heart rate over 100, feeling hot etc. A thyroid storm is rare but causes severe hyperthyroid symptoms and the body temperature may be as high as 105 - 106 F (40.5 - 41.1 C). A thyroid storm is a life threatening medical emergency.
Heat stroke symptoms include:
Nausea and vomiting
Dizziness or vertigo
Hot, flushed, dry skin
Rapid heart rate
Shortness of breath
Blood in urine or stool
Increased body temperature (104 to 106 F)
Confusion, delirium, or loss of consciousness
Heat stroke is life threatening medical emergency and can be fatal. Immediate treatment is needed to avoid permanent organ damage.
I forgot to mention i listed the heat stroke symptoms since you mention going out into the heat. Hyperthyroidism or thyroid storm does not cause heat stroke.
I had high temps when I was dealing with an unbeknown to me "thyroid storm', due to untreated graves/hyper/toxic goiter.
However, I was never told to stay indoors with AC. I live in Texas & we all know how hot it gets here...
But "no, I never had anyone in the health profession tell me to stay out of the heat at that time.
Thank you all for responding and I am sorry it took me so long to respond. I do have a dr appointment in a few weeks and plan on seeking the help from and endo as my gp is not that interested in my thyroid and thinks I am "fine" because I am within range. I had to argue just to get the T4 and T3 tested and was told it was an antiquated way of testing, I know it was a load of bull but I am stuck with them due to other health issues. I have severe back problems and they are the only ones in my area that have helped.
goolarra was right it is due to our bodys inability to keep up with temp changes. My mother in law that found a great website. She has a tendency to not believe things unless you have proof so I was stumped all I knew is what my dr told me. Here is a link to the website that explains it. http://www.wellnessresources.com/weight_tips/articles/body_temperature_and_thyroid_problems/?fb_action_ids=10200130201005530
To Red_Star and Totie I am not sure if it makes a difference but I have hashimotos. I don't think I have to worry about a thyroid storm. (?) From what I looked up it seems you have to be hyperthyroid. Even though I know a person can fluctuate I don't think I have that problem. Hopefully soon I can get into a good endo and get my mess straightened out. I went in for a regular check up and was told as my dr was walking out the door that I have Hashimoto's. I had no idea what it was until I got home and started researching. As I did a lot of red flags popped up and I was like huh no wonder!!!
Thanks again for all of your help, I am so glad I found this forum and the people in it are so awesome.
Best wishes, Sissie
