I don't know if there is an absolute limit, per se. Just be sure that if you get sick again, you mention it to the doctor.
Good question, though!
I've been on long term high dose steroids in my past due to ulcerative colitis and expect to have again with my Lupus. I've not had my bone density tested and frankly have just not wanted to know. It has been 16 years since I took them. Keeping your doctors aware of your previous short term uses is good but working to replace any density you may have lost is key to ensure you are in shape for any future requirements. Up your calcium and vitamin D intake and do weight bearing exercises. It is when you don't play catch up that you can have issues.
If you start turning into a man you've had too many.
LOL - I'll try to remember that! Hm, my voice hasn't gotten lower, wait, yes it did! Oh yeah, that's because I lost my voice, lol. Ok, no weird facial hair or extra appendages. Didn't bulk up overnight. Hm, nope! I guess I'm ok! LOL
Thanks for all the replies, guys! I appreciate it. :)
