I was diagnosed with sarcoidosis 10 odd years ago and had it for about 6 years prior to that. Short term prednisone is less of a problem than long term. The side effects can be as bad as the disease. While I was on a high dose I could have (and possibly did) eat a cow- whole - alive- with hooves and horns. I packed on an enormous amount of weight in only a few weeks, and haven't lost it at all. My respirologist failed to tell me about that side effect; also forgot to mention that prednisone removes calcium from bones, also it removes potassium. Your doctor should be monitoring these. I found out in an emergency ward. I had to have three bags of potassium injected and boy it hurt! Also was getting lots of needles for calcium that had been depleted. The extra weight is a big problem as the need for food can be overwhelming. It is not just being extra-hungry for dinner; it is a painful don't-care-if it-is-cooked- kind of hunger. The weight does not go on like normal fat. You get a large stomach and moon face, with time a buffalo hump, and possibly Cushing disease. I would suggest you avoid processed foods as much as possible. Follow the Canada food guide and eat the maximum vegetables and fruits, and the mininum carbohydrates, drink lots of water; green tea is a good choicE. Be careful in the sun. It may be that you have the acute type of sarcoidosis and your use of prednisone will be short-term. Don't go off the steroids without a doctor's assistance. Good luck.
