I'm interested if anyone was warned by their surgeon about regains and how much is considered to be normal or acceptable. I lost 100% of my excess but have slowly regained 9lb that won't budge. I know it's not a lot but I can't get my head around the regain when my eating hasn't change much. My surgeon said this is normal. My sister in law had a bypass and she also regained a stone although she is still slim.
