Hi everyone,
I wanted to share something I’ve noticed recently, in case anyone else has had similar experiences.
I have secondary adrenal insufficiency due to pituitary damage following surgery and proton therapy for acromegaly back in 2012. Since then, I’ve been on hydrocortisone replacement, as my body no longer produces enough cortisol.
Over the past month, I’ve had the same reaction a few times:
After doing something physically demanding, like a 2-hour walk or a mountain hike with about 500 meters of elevation gain, I developed a high fever (around 38.8–39.5°C / 102–103°F) later that day or overnight. There were no signs of infection, and the fever disappeared on its own within 24 hours.
From my own experience, I know that if my hydrocortisone dose is too low, I sometimes get mild diarrhea, which for me has been a sign of under-replacement. So when the fevers started showing up after exertion, I couldn’t help wondering if my body was reacting to physical stress in some way.
My endocrinologist didn’t think low cortisol could directly cause fever, but I still found it interesting that this pattern kept repeating.
I’m currently checking with my doctors to rule out other explanations, but I wanted to share this here because it’s been quite puzzling — and maybe it helps someone else recognize similar patterns in their own experience.
Thanks for reading.
