Pull this leg and it plays "jingle bells"
No offense Bro, but don't believe everything you hear especially from a Doc. I've been in the medical field for 12 years. I deal with MD's every day. I eat them for breakfast. Why do you think they call it "practicing medicine" that's how they excuse all the mistakes they make.
Seriously...
Prednisone is in the class of steroids called "glucocorticoids". Also called adrenocortical steroids they are also naturally occurring in the body (called cortisol,the equivlent of 5mg of prednisone is normally produced daily by the adrenal cortex).
Cortisol regulates the metabolism of proteins, carbohydrates, and lipids. SPECIFICALLY, it increases the catabolism or breakdown of protein in bone, skin, MUSCLE, and connective tissue. Cortisol also diminishes the cellular utilization of glucose and increases the output of glucose from the liver. The presence of cortisol is essential to nor-epinephrine-induced vasoconstriction and other necessary neurological pathways for survival under stress (fight or flight). I could go on and on about chemical processes but I'll spare you the boredom.
Prednisone is mainly used to treat inflammatory disorders: autoimmune diseases (arthritis), lung disease (asthma), severe allergic reactions. If you have been on it for a while (more than a week or so), you have to taper off it because as with Test, your body decreases natural production. If you come off it to quick and your body doesn't increase it's own, you go into an adrenal crisis and you can die. Prolonged use (have you seen Jerry Lewis lately?) causes cushing syndrome (moon face, hump back, all weight (fat) on the torso, spindly arms). Diabetes, Glaucoma, fibrosis of the lungs, osteopenia (thin bones), muscle wasting, ......
Tell your friend next time she opens her trap..don't say anything. That's what happens when you get your education from Cracker Jack University.
That will be all, if you need me I'll be in my office.
