Everyone is different, I'm pre op so? but every persons video I've watched on you tube lost 100lbs in 6 months as did a lady I met. She said she could just lay in bed & lose weight. One lady that had it years ago still falls in the obese range. From the reading I've done so far, I gather the first 100lbs is the surgery and after that it's about sticking to the diet and no getting around the exercise. I've read others saying they are a year or more out and their stomachs stretched so now they're back to eating a full plate of food. I asked my nurse about this. She said no, the pouch remains the same size as right after surgery. She said she can only force in 2 spoonful's, never gets hungry and has to remember to eat. Makes me wonder why we're born w/such a large stomach? I think people that gain weight back or never loose enough, weren't committed to making life changes and working out regularly. If I'm wrong, please correct me. My Dr said no scales at home, so I asked then why do you weigh me? lol I think it's more inches than weight, at least at times. Going by my nurse and what others have said. But, the first hospital I started with said the pouch would enlarge somewhat over time so I don't know for sure until I ask my Dr.
