I have only lost 7 lbs since my sleeve surgery and I am 1 week post op. Is this normal?? I thought I would have lost more by the 1 week mark.

most of us lose somewhere in the `15-25 lb range the whole first MONTH, so yes, seven lbs after one week is fine. In fact, some don't even lose that much because they "gain" weight from the IV fluids they give you in the hospital, and it can take few days for that to work its way out of your system.

I gained 10 lbs within 24hrs after surgery (IV). It took a couple of weeks for the excess water from the drip to come off on me. I'm almost always dehydrated though. The weight lost in the beginning is mostly water, so later when the weightloss starts slowing down, it's because you're losing fat not water anymore which takes 3500 calorie deficit to lose one pound of fat.

I only lost 5 lbs by my first post appointment 7 days out. I’m 17 days out now. I know I’ve lost more based on the way my clothes fit but I haven’t weighed myself yet. Waiting for my phase change appt next week.
