My morning temps have been low for a long time. Usually around 96.2F. Afternoon and evening temps don’t even go above 97.6F. I’ve had an immense amount of brain fog for 3 years now. Is thyroid and low cortisol usually the reasons for low basal temps, or is there other reasons I should know about?
Most recent labs:
Cortisol 10.6 (4.6-20.6)
TSH 0.63 (0.40-4.50)
Total T4 5.9 (4.5-12.0)
Free T4 1.1 (0.8-1.8)
Total T3 99 (76-181)
Free T3 3.5 (2.3-4.2)
Reverse T3 7 (8-25)
Antibiodies always come back negative
All these labs are very consistently the same over multiple blood tests btw.
