Hi There dinkydee,
I know what you are going through with the weight loss issues. I used to be a normal healthy weight and then I lost about 20lbs and remained there for about 2 years. Then all of the sudden I started gaining like there was no tomorrow. It was completely frustrating b/c there was no explanation for it other than "age"...and I was only 25. I put on about 40lbs which put me about 20lbs above my normal weight. Then I started to get sick to my stomach all the time and massive D. The real kicker...I kept gaining weight. I finally went to my Dr. and I was like "How is it possible that I keep gaining weight when it seems that none of my food stays in me". For this they offer no explaination. A few blood tests and biopsies later I was DX wtih Celiac Disease and PCOS. They figured that the PCOS was making me gain weight despite a malabsorbtion issue. My health briefly leveled out and I stopped gaining but was not ever really able to lose more than 5 lbs. Go forward 4 years later and I am sick again and Dx with Crohn's. I am still overweight by about 25lbs and I am deficient in lots of vitamins which means malabsorbtion issues...yet my weight is still there. The only thing that took weight off of my we prednisone...which is completely opposite of what they say it does to you. I suspect that I had weight loss while on prednisone b/c of inflammation or something. In any event, I am now on a path to get my vitamins in check and I am hoping that it may help to resolve the issues with weight. I of course eat a healthy diet and I exercise moderatly when I can. I could exercise more but it does not help I swam for 2 hours every morning for months and saw not a lick of weight come off. I was just more toned. Sorry I don't have the magic cure but I just wanted to let you know you are not alone with your struggle.
All the Best
