Regular body temp 97.5/97.6 all thyroid labs came back normal. What might be causing this?
Do you feel cold? Do you feel chilling when everyone else in the same room feels comfortable? If, yes; then you need further work up including CBC to rule out "anemia" as well as other disorders that could also cause "hypotension" ; "weight loss".
But, if the answer is no; then it could be just a normal body temperature for you.
