Hi, all. I had my DS surgery 19 years ago yesterday. I originally lost about 145 pounds then regained 30. Over the last year, I took off the 30. Then my gall bladder went haywire and I had it removed. I could barely eat for 8 weeks and took off another 15 pounds. I am now entirely too thin and am unhealthy. I never in my life thought I would have that issue! I am doing strength training and pounding protein like crazy. Does anyone have any suggestions on how to intentionally gain weight, preferably muscle mass and not fat? Thanks!
