I got bypass on 7/19 and I'm trying to figure everything out. My nutrition guides don't say anything about max serving size or times to consume thing. Day 5 I was supposed to start incorporating Protein drinks so I tried a Protein shake (Premier Protein with some pb2) and I was sick the rest of the night/ next day. I'm trying to figure out if it's what I'm eating or how fast I'm eating it.

How long did it take you freshly post op to eat a Popsicle, drink some Soup, have a shake?

What are the symptoms that you should stop (I don't get that full feeling anymore so I have no idea when enough is enough)?

Thanks!

I am 3 years post-op RNY gastric bypass surgery. Generally before surgery, your surgical team provides a book of directions for meals post-op. So I am kind of surprised that you were not given specific directions. So you probably need to verify all the daily requirements (food types, meal volume, Protein, Fluid and vitamin). This is essential information and you definitely need this. Some individuals are having mini-gastric bypass which is a different operation and I am not completely sure how the post-op requirement vary. Those that have a mini-gastric bypass seem to tend to have been given less in the way of guidance.

The three most important elements after RNY gastric bypass surgery are to meet your daily protein, fluid and Vitamin requirements. Food is secondary because your body is converting your stored fat into the energy that drives your body. Thus you lose weight.

Weight loss is achieved after surgery through volume control. You begin at 2 ounces (1/4 cup) per meal and gradually over the next year and a half increase the volume to 1 cup per meal. With this minuscule amount of food, it is next to impossible to meet your protein daily requirements by food alone, so therefore you need to rely on supplements such as Protein shakes.

Right after surgery, your body is in a major heal mode, so several individuals find it difficult to meet their daily protein and fluid requirement. But just keep working at it and you should be able to get there in a week or two.

Thanks for your reply James. I should clarify, I have information for what stage I'm on, what foods I can eat, what Vitamins to take, and how much Protein and liquid my goals are for the day. Im trying to be really good on all that.

What I've noticed is that in trying to follow the guidelines they gave me, I get sick still. So I was trying to find out the parts my info doesn't clarifying.

I'm hoping to hear some experiences or guidelines on how long it takes new post op people to eat a Popsicle, or drink a protein shake. For example if I eat a Popsicle and it takes me 15 minutes is that too fast? Should it be taking an hour?

Thanks!

If you can eat a popsicle in 15 minutes, that is not too fast. There is basically no food in a sugar free popsicle. It will count towards your daily Fluid requirement. Some individuals seem to have a problem with Protein shakes where it takes them a couple hours to down one. I never had a problem there. But since you just had surgery it may take you a while to meet this requirement. In my case I had to drink 3 protein shakes (16 ounce) per day in the beginning.

Some people become lactose intolerant after surgery. If I drank milk or anything with lactose, my stomach hurt and then there was a quick trip to the restroom with diarrhea. This condition went away after about 2 months. Some protein shakes use lactose.

Try a different brand of Protein shake. I could not tolerate the Premiere Protein shakes, but lots of people on this board seem to like them.
