Hyperparathyroidism Support Group
Hyperparathyroidism is overactivity of the parathyroid glands resulting in excess production of parathyroid hormone (PTH). Increased PTH consequently leads to increased serum calcium (hypercalcemia) due to 1) increased bone resorption, allowing flow of calcium from bone to blood, 2) reduces renal clearance of calcium, and 3) increases intestinal calcium absorption.
Yes. I am 50, and up until my early 40s was in excellent physical shape, although I never really thought so because I was comparing myself with people who were in even better shape! Nonetheless, I was able to complete a marathon the year I turned 40 despite having done most of my "endurance training" in bars and restaurants....;^)
What I am trying to get across is that I was a fit, muscular person with a good energy level.
After that, though, I sort of got...tired. I explained it away by a lot of different means: I was moving away from my work as an actor, I was focused on my relationship and having my daughter, I had stopped working out so much, therefore my energy level was lower, and I was just plain getting older....I thought this was just how a person's 40s were supposed to be. And I didn't look bad at all. Heck, I was an outright hottie!
But the reality was, I just had no reserves. Working out didn't feel good, I was exhausted and stiff afterward, and the stiffness didn't get better, it just sort of wore off. I can also relate to that sense of running out of steam after a few hours and being unable to do another thing--it is different than being tired in ways that are hard to explain.
I now believe that my PTH and blood calcium levels began climbing when I was in my late 30s, (correlating with a decline in cognitive/executive function) and the physical symptoms got going in earnest in my early 40s. (Of course, my disease progression would have been considered "asymptomatic" according to the guidelines.)
Looking back on it now, I should have understood that something was different, and that overall fitness and energy just don't decline precipitously like that. But I was conditioned to believe that if you don't move it, you lose it--and I thought that since I wasn't moving it, maybe I deserved to lose it.
Now, almost a year post-surgery, my energy level is coming back. Unfortunately, the strength, balance and muscle tone I lost are going to take some time, and now I have osteoporosis to contend with as well. But there is a qualitative difference in how it feels to exercise now--I don't just feel like I'm spending all the money in my physical bank account, or pushing myself through on determination alone. It is a profound difference.
I hope you can take this specific presentation of feeling unusually stiff and exhausted after muscle exertion, along with my anecdote, to your MD to help her evaluate your other symptoms and labwork.
