many people who lose a large amount of weight will still have pockets of fat (adipose tissue) in the abdomen. some will have this surgically removed (tummy tuck) or have liposuction so perhaps a consultation with a surgeon who performs these procedures would be in order. it is unlikely that "a build of waste" is the reason for her residual large abdomen.
big stomach but lost 100 lbs. my daughter has lost 100 lbs. she is thin everywhere but her stomach is still as large as ever. it is a bit jiggly but a bit hard. her primary took xrays and said all she saw was a build up of waste. what could be the problem? thank you.
