Last minute surgery and Liquid pre-op diet question.



Recommended Posts

I just had my final Dr. visit yesterday (Wednesday) and he had an opening for Monday; I took it. :) My question is that since I do not have the traditional 2-3 weeks of pre-diet and a full week of liquid diet, what is my best option?

I just checked out the options from Walmart and they have a decent selection of ready shakes:

  • SlimFast (high carb/med sugar, moderate Protein, low fat)
  • Atkins Advantage (very low carbs/sugar, moderate protein, high fat - 9/3.5g)
  • Boost - High Protein (high carb/low sugar, high protein - 25g, low fat)
  • EAS Lite - (moderate carb/low sugar, high protein - 20g, low fat) - not Meal Replacement, designed for post workout.

I think the purpose of the pre-op diet is to shrink the liver to make the surgery safer; if that is the primary objective, then from the above, the Atkins should be best.

Is there something better that I can purchase local? I got a 4-pack of the Atkins and it tasts ok, but wanted advice before buying more.

My plan was to drink 4-5 meal replacement shakes and then drink 1-2 V8's, but I just noticed that they have 11g sugars each.

That is exactly what I bought for post-op suppliment, but I was not sure about using it for pre-op. My RD wants me to use nothing but whey Protein Isolate post-op and this is a mix of Isolate and concentrate, but it is half the price of Isolate and I have read a ton of body building forums about the difference. I discovered that the Isolate is better for fast absorbtion after exercise and the concentrate is overall healthier because of the extra amino acids. So I figure that this is a good compromise.

I may have answered my own question from another post in this forum who said the liquid diet should be ~500 calories and no more than 10g carbs per day. It looks like since my focus should be on carbs, I should drink the Body Fortress stuff with 16g carbs per 500 calories vs the Atkins at ~20g per 500 calories.

Hmm, is it total carbs or 'sugars" to keep under 10g per day?

I only had six days of preop diet too. I used muscle milk premade banana creme flavor as a Meal Replacement for Breakfast and lunch and drank crystal lite and diet cranberry juice, Water, etc. Went totally off caffieine and the headache was mean! I got to eat 3 oz of Protein a night with non starchy veggies. That meal at night made it so much easier! I had talapia or chicken and green Beans or something like that. I also walked two miles each day (required). I hope that helps. I lost 9 pounds in 6 days doing that and I was not so deprived because I got to chew for my evening meal.

My pre-op was a bit different... it was two weeks super low carb (which I was doing anyways) and then two days of Clear liquids. I would go with whichever is lower carbs.... lowering your carbs helps your liver shrink and that is the ultimate goal of the pre-op diet.

Also, from personal experience the EAS carb advantage from Walmart aren't horrible. I can't drink any except for the regular chocolate one, but that ones tastes pretty good to me.

Good luck!

I would suggest that you ask your surgeon or his staff what he suggests under the circumstances as you are primarily doing the diet for him - some surgeons do a pre-op diet and some do not. Since the primary rationale for the pre-op diet is to improve liver condition to make the surgery easier for the doc (and therefore on you as well - you want to keep the guy who's digging around inside you happy,) I would ask him.

Since fatty liver is the condition that they are trying to improve upon, I would think (in my non-expert opinion) that the higher fat content of the Atkins variety would be the one that you would want to avoid. I would go for the lowest calorie and highest Protein variety at this point and not get too worried about carb count or anything else until after your surgery (if your doc even cares about counting carbs - many do not.)

Does he do a clear liquid diet the last day or two as most do? If he does, then you should also seek out some of the Isopure clear liquid Protein drinks, (or similar products) and maybe make up some hi-pro Jello with unflavored Protein powder (which is usually acceptable as a "clear liquid".

When I go on my pre diet, I'm only allowed to choose from 3 or 4 different Protein Shakes. I know one of them was Undry which you can only get online, but I believe EAS is the other one. I'm not sure how it tastes, but it's doctor recommended! :) Do you have a GNC local? I know they are more expensive, but there is more to choose from plus, the people there know what they are talking about. I actually really like going in there! Good luck!

No, I have no requirement for two days of clear diet, but I do need to take a colon clense the day before (Magnesium Citrate) at 3pm and 7pm and only Clear Liquids after I start that.

As far as GNC, I do have one of them local, but I have lost all faith in them when the lady told me all of the Protein powders are mostly the same, it doesn't really matter which one I choose.

I have done further google'ing and seem to find that low carb is better than low calorie or low fat diets. But I agree about contacting your surgeon. Mine does not seem to have a preference because it is mainly for the habit for the post-op diet, but I just want to optimize my personal surgery success.

      Four days post surgery. I am sipping as fast as I can and getting NO WHERE near the goal of 60 - 80 grams of protein or the 64 oz of liquids. I just feel FULL. I don't know if it can still be the gas build up (I would think by now that would be gone) but it is a struggle to drink. And so far I have not had the nausea or spasms and don't want to wander into that territory by pushing too hard with liquids. I about passed out today as it was my most "strenuous" day. Went from second story to basement for shower and I was sure I was going to pass out. Looking back on my last few days I have had a total of less than 1000 calories. Am I just not getting enough nourishment in me? Once again a friday where I can't get ahold of the doc until Monday rolls back around so I am hoping maybe someone here has some experience on how to keep energy going. I do have fibromyalgia too and that may be where some added fatigue comes into play. How did you all fair with the goals the week after surgery?

      2 days until I fly out to San Diego to have my Bypass Surg. in Tiajuana Mexico. Not gonna lie, the nerves are starting to surface. I don't fear the surgery itself, or the fact that I'm traveling alone, but its the aftermath that I'm stressing about the most, after this 8 week wait. I'm excited to finally be here, but I am really dreading the post surgical chapter. I know its going to be tough, real tough and I think I'm just in my head to much now that the day i here. Wish me luck, Hopefully I'm one of the lucky ones, and everything goes smoothly. Cant wait to give an exciting update,. If there is anyone else have a June bypass or even a recent one, Id love to have someone to compare war stories with. Also, anyone near San Antonio Tx? See ya soon with the future me. 💜

      I am new here today... and only two weeks out from my sleeve surgery on the 23rd. I am amazed I have kept my calories down to 467 today so far... that leaves me almost 750 left for dinner and maybe a snack. This is going to be tough for two weeks... but I have to believe I can do it!

      Hey everyone. I'm new here so I thought I should introduce myself. I am 53y/o and am scheduled for Gastric Bypass on June 25th, 2025. I'm located in San Antonio, Texas. I will be having my surgery in Tiajuana Mexico. I've wanted this for years, but I always had insurance where bariatric procedures were excluded. Finally I am able to afford to pay out of pocket.  I can't wait to get started, and I hope I'm prepared for the initial period of "hell". I know what I have signed up for, but I'm sure the good to come will out way the temporary period of discomfort and feelings of regret. I'd love to find people to talk to who have been through the same procedure or experience before. So I look forward to meeting you all. Hope you have a great week!

        I'm so happy for you! You are about to change your life. I was so glad to get the sleeve done in Dec. I didn't have feelings of regret overall. And I'm down almost 60 lbs. I do feel a little sad at restaurants. I can barely eat half a kid's meal. I get adults meals often because kid ones don't have the same offerings at times. Then I feel obligated to eat on that until it's gone and that can be days. So the restaurant thing isn't great for me. All the rest is fine by me! I love feeling full with very little. I do wish I could drink when eating. And will sip at the end. Just a strong habit to stop. But I'm working on it! You will do fine! Just keep focused on your desire to be different. Not better or worse. But different. I am happy both ways but my low back doesn't like me that heavy. So I listened (also my feet!). LOL! Update us on your journey! I'm not far from you. I'm in Houston. Good luck and I hope it all goes smoothly! Would love to see pics of the town you go to for this. I've never been there. Neat you will be traveling for this! Enjoy the journey. Take it one day at a time. Sometimes a few hours at a time. Follow all recommendations as best you can. 💗

        Thank you so much for your well wishes. I am hoping that everything goes easy for me as well. We don't eat out much as it is, so it wont be too bad in that department. Thankfully. Also, I hear you regarding your back and feet!! I'd like to add knees to the list. Killing me as we speak! I'm only 5' so the weight has to go. Too short to carry all this weight. Menopause really did a doosey on me. (😶lol) My daughter also lives in Houston. with her Husband and my 5 grand-littles. I grew up in Beaumont, so I know Houston well, I will be sure to keep in touch and update you on my journey. I may need some advice in the future, or just motivation. Thank You so much for reaching out, I was hoping to connect with someone in the community. I really appreciate it. 💜

      On day 4 of the 2 week liquid pre-op diet. Surgery scheduled for June 11th.
      Soooo I am coming to a realization
      of something and I'm not sure what to do about it. For years the only thing I've enjoyed is eating. We rarely do anything or go anywhere and if we do it always includes food. Family comes over? Big family dinner! Go camping? Food! Take a short ride or trip? Food! Holiday? Food! Go out of town for a Dr appointment? Food! When we go to a new town we don't look for any attractions, we look for restaurants we haven't been to. Heck, I look forward to getting off work because that means it's almost supper time. Now that I'm drinking these pre-op shakes for breakfast, lunch, and supper I have nothing to look forward to.  And once I have surgery on June 11th it'll be more of the same shakes. Even after pureed stage, soft food stage, and finally regular food stage, it's going to be a drastic change for the rest of my life. I'm giving up the one thing that really brings me joy. Eating. How do you cope with that? What do you do to fill that void? Wow. Now I'm sad.

        I hope your surgery on Wednesday goes well. You will be able to do all sorts of new things as you find your new normal after surgery. I don't know this from experience yet, but I am seeing a lot of positive things from people who have had it done. Best of luck!
