Does anyone else with CVID have an issue with weight GAIN! Everything I see says that weight loss is a symptom, but I didn't start gaining until I began my IVIG treatment. My immunologist seems to think there is no correlation and just says "well we all struggle with our weight :-/". He's a great doc, but I have a hard time believing this is normal. Considering all the GI trouble I have, my body can't be absorbing enough of what I eat to make me gain weight!
