basal temperature measurement

Has anybody taken any readings of their basal temp?

it's seems that it can be a good indicator for hypo.

I took 3 readings a day over a number of days, here are the results.

36.3, 36.2, 36.4, 36.4 and 36.3 (Celsius).

Now, they say a healthy person should be a consistent 37.

I went to the doctors with this and she said " what should a normal person be". Followed by " have you tested anybody else".

It will be interesting to see what you guys achieve.

Hi I have been on levo for 28 years and never felt well, after reading sttm book I also took basal temp for 2 weeks, mostly they were 34.5 to 35.2, I pushed to see a endo as I felt so ill and after juch testing ended up with a diagnosis of panhypopituitarism, unfortunately doctors dont pay to juch heed to temp charting but I advice anyone to advocate and educate themselves and find a doctor who will listen and act, not easy I jight add


Hi im on 75 levo was diagnosed this year hypthyroid and every morning I take my basel temp it is never over 35.3 usually 35.1 but can be 33 takes no interest at all in these results and will not up my dose


Hi It is a good indication but not fool proof. My temp never goes above 35.4 unless a severe fever. My thyroid has been stable for many years, same before and after.



My temp is 36.5 at normal, so are my children's . My thyroid is stable and the kids have no problems.

They or I can have a low fever at 37

When I first went to my doctor (16 years ago) and quoted the basal temp test (haha) it was lower than my stable normal of 36.5-cant remember what though.
