Normal T4 normal TSH, thyroid problems ?!
Question: Normal T4 normal TSH, thyroid problems !?
A blood test revealed I have normal t4 level of !.8 and a normal tsh level of !.88!. However, I still think I have some kind of thyroid problem (hyperthyroidism !? ) based on pregnancy losses I've had and the inability to gain any weight and tachycardia, chronic diarrhea, heat intolerance!.
What is t3 and since my doctor didn't check it, could that be a cause of hyper or hypothyroidism!. Please help, I'm confused ! Any knowledge you might be able to share is greatly appreciated!.Www@Answer-Health@Com

Answers:
I am no endocrinologist but I am a medical student!. Your TSH may be "normal" but it is at the lower end of normal (which is 0!.3 - 0!.5 with a best level around 2!.5)!. Your T4 doesn't sound right!. A "normal" T4 is generally from 4!.5 to 11!.2!. I think you meant "free T4" which is normal from 0!.9 to 2!.0!. You are just on the cusp of a low/normal FREE T4!.
a really low T4 would indicate "secondary Hypothyroidism" in which the pituitary gland is not producing enough TSH which produces a low T4!. There are a lot of reasons to this could occur but a doctor should send you for a MRI of the head if this is the case!. I know that this could also indicate a difficulty with getting pregnant but I don't know about miscarriages!.
A thyroid gland releases mostly T4 and some T3!. T3 is the active form and much more potent than T4!. Certain cells in your body have the ability to turn T4 into T3!. In general, the amount of "free T4" is an indication of how well your thyroid is functioning!. Some people may have difficulty converting T4 (thyroxine) to active T3, and certain medications can interfere with this process (like lithium)!. Usually it is not necessary to check T3 unless the doctor suspects an inability to convert T4 to T3!. Really, if you are unsure as to be referred to an endocrinologist for a second opinion!. If you have had multiple pregnancy losses a fertility specialist may be helpful as well!.
One can have an elevated T3 with a normal T4 (a T3 thyrotoxicosis) but this is less common, but should be checked out with someone presenting with clinical signs of hyperthyroidism!.
Do you have high blood pressure!? It is rare but some poeple have a "pheochromocytoma" which produces
uncontrolled high blood pressure,
tachycardia
Palpitations (abnormal beats or a "fluttering" feeling in the chest!.
Anxiety often resembling that of a panic attack
Diaphoresis (sweating)
Headaches
Pallor (Paleness)
Weight loss
There is another condition called carcinoid, which is really rare (I hope you are not a hypochondriac!) but can produce:
Flushing
Diarrhea
Wheezing
Abdominal cramping
Peripheral edema (swelling)
How chronic is your diarrhea!? Are you having more than 3 stools a day!? Are they bloody, black and tarry, yellowish, associated with mucus!? Have you lost weight recently!? These are all signs that you should bring up with your doctor!.
Hope this helps!.Www@Answer-Health@Com

Are you on a med for either and if so how much!? Your body makes its own t3 and t4 if you have too much you are hyper and not enough you are hypo!. The symptoms you are saying are indicative of hyperthyroidism!. I'm not a doctor so go back have him test your t3!. There is a book by Broda Barnes that you can get called "Thyroid the unsuspected illness" It should answer all of your questions but still go to the doctor!.If you are on a med that has t3 in it it might be adding to the hyper symptoms!. Please get enough water to help hydrate cuz you are losing a lot of electrolytes have a gatorade to replace the other electrolytes until youI get this problem solved!. I don't know how old you are but this is dangerous at any age!. This is fixable but go back to the doc!. What did they say about the hypre symptoms!?Www@Answer-Health@Com
