your new stomach is not big enough to cope with this any more and if you do eat and drink together, you may vomit. Can also lead to dumping syndrome

if you had bypass, it's because your pyloric valve has been bypassed, and you just have a stoma now (a small hole where digested food goes directly into the small intestine). If you drink Water too soon after eating, the food gets washed from your stomach too quickly.

  1. There is not enough room for both food and Water in your new pouch.
  2. Water will flush the food out of your pouch quickly. This means a couple of things.
    1. You may get dumping syndrome.
    2. Your pouch won't be able to send the signal to your brain that you're full. So, you'll get hungry again sooner and/or you will need to eat a larger amount to be satisfied.
  3. The food needs to sit in your pouch for as long as possible, for digestion - so you can absorb as many of the nutrients as possible.

I am copying my post from another thread.... I am pre-op and one of the most concerning restrictions of VSG for me is the 30 minute before and after rule of drink/eat. I have always been a constant sipper and my husband & I have a lot of "wine & dine" business/social engagements. I had assumed the drink/eat rule was due to filling up in liquid and then not having room for food.....wrong. After researching the mechanics behind this rule, I discovered the reason why. The video below shows how we can easily sabotage ourselves by breaking the rule! https://youtube.com/shorts/oNdeGkkwqlw?feature=share

      tl:dr at bottom,
      I could use some advice. I went to see my dietician today (not a bariatric surgery dietician, I can explain why I am seeing her if you want to know). She knows I am going to have weight loss surgery as long as I hit the goal weight my insurance told me I need to be at. I have to be at the goal weight by June 24, 2023, in order for my insurance to pay for my surgery.
      I had a weigh in the doctor's office a couple of days ago and weighed 301, my scale at home said 302. However, on the same day, the scale at a friend's house said 313. 
      I knew I had this Dietician appointment two days later and I knew she would weigh me. I continued to weigh myself at home (after getting new batteries) and I was at 302 then 299 and today at home I weighed 303, right before my appointment, when I got to her office I was weighed and it said 313.
      I am concerned about what to believe since the doctor's office and my scale show similar numbers. I also bought a new scale today and it said 313. 
      The Dietician told me I needed to eat more protein, which honestly I struggle with. she said I needed 150 grams!!  I said are you kidding? that seems like a lot.  She used my weight to come up with this number. 
      Should I really be trying to eat enough protein for a 300-lb person or should I be eating protein for a goal-weight person (mine is 170)?   
      also, my clothing is loose like I lost the 20 lbs mine and the doctor's scale shows, and not 10 lbs like everyone else's scale shows. Also, I have always naturally been more muscular even when I was 120 lbs and did not eat any protein aside from what is in plants. 
      tl:dr- should I be eating enough protein to support a 300lb person or should I be eating protein for a "normal" sized person? AND should I trust the Doctors scale more so than the Dietician's scale?

        I would love to be your accountability partner. I had the sleeve in 2021, so maybe I can give you some insights.

        Please message me back, looking forward to hearing from you!
