Help!! slim fast optima diarrhea



Recommended Posts

Hey guys, I am a new member who is in the pre-op stage. This is my 4th day on the pre-op diet, with 9 days remaining.

My pre-op diet is to drink 3 slim fast optima and 1 Protein Shake (from the doctor's office) for the 1st 3 days. (now) and then to add one garden salad and take away one slim fast for the remainder.

My problem is that I started to feel nauseous after the 1st day, had diarrhea after the 2nd day, and the night of the 3rd day, I woke up with leg cramps (I think because of dehydration), diarrhea, and am somewhat nauseous.

I've done some research about the slim fast, and found that many people think the slim fast is too high in sugar, which causes the diarrhea, which can cause renal failure.

Ok, I know I should consult my doctor when they open on Monday, but I would like to hear about if you've had similar experiences.

(pss) I am going to drink lots more Water today...but I don't think that is enough of a solution.

Are you lactose intolerant? that can be the cause of your diahrea. Slimfast ready to drink shakes have milk in them

liquids in, liquids out...... Very common! I would say that the pre op diet is a shock to everyones system considering how we were eating before pre op.

I really don't know if there's any way around it but it doesen't hurt to call.

Good luck

I am on day 7 of my pre-op- did not have any of those problems at all. What I am doing is not slim fast... I went to GNC and got shakes that are sugar free (Lean Body- chocolate Ice Cream flavor) my doctor said that the shakes need to contain min 15 grams of protein- they have 25 grams (keeps u fuller)

so I drink one for Breakfast, then drink 2 bottles of Water in between Breakfast and lunch, I also have one banana in this time as well, then lunch is a 2nd shake, and dinner is 6 oz of chicken or fish, veggies and small salad with ff dressing.

I could easily switch dinner for another shake- I have not felt hungry (except yesterday) this whole week. I have not had any bowel issues either....

I would up your intake of H2O and at the very least add a piece of fruit.< /p>

If your doctor's office is passing off a person as a Nutritionist and they arn't make sure your insurance company is not paying for that service and request a referral to a real one. This is a key person in your journey.

Good Luck!!!

(ps) I feel quite sure that the doctor will not speak to me, but that the "nutritionist" who is not a nutritionist will try to answer my questions.:confused:Help!:frown:

(pss) I am going to drink lots more Water today...but I don't think that is enough of a solution.

I would ask your doctor why you are on a high carb, high sugar, liquid diet to begin with. Seriously, ask them for studies showing that a high carb, high sugar, liquid diet is superior to a low carb, solid food, liver shrinking diet. Tell them you need references to the study that supports this is the best diet.

BTW, what are you talking about that drinking slim fast will cause renal failure?

Thanks so much for the reply and the good advice. After I began to feel to sick, dizzy, faint, bowel problems, and waking up in the middle of the night with severe leg cramps, I knew that I was dehydrated. I just did a key word search and found many posts about this and a few that had to go to the hospital, one with renal failure, and another just had to receive an IV to rehydrate.

I am going to ask my doctor if I can use another liquid drink. (I thought that Slim Fast was a liver shrinking diet...just becasue I figured that they knew best)...Thanks for the suggestions.

WOW, my preop diet is way different...pout pout pout!!!

On mine they have me drinking four 4oz Protein shakes an then 2 cups of no sugar added juice or skim milk, then unlimited amounts of broth, sugar free popsicles and sugar free Jello.

Just fyi many of the sugar free products have the side effect of diarrhea so have to be careful when consuming those...

Good luck on your surgery

This is a late post, but I find the smoothie King gladiator shake is very good. You can mix it with strawberry and pineapple, and it's out of this world!:thumbup:

My doc told me last Friday to try Slim Fast Low Carb. 20 grams of Protein. Could not find them in the store so ordered from Amazon. I like the taste of Alim Fast waaaay more than some of the other drinks.< /p>

      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'm in Houston so kind of near you and had the sleeve in Dec. Down 61 lbs. Feeling better. Was definitely worth it. I hope the everything is going well for you. Update us when you can!

        I am back home after my bypass surgery in Tiajuana. I'm post op day 4. Everything went great! I guess I'm one of the lucky ones who have not encountered much pain at all, no nausea thus far and I'm having no problem keeping down broths and water. Thank you for your well wishes. I cant wait to keep up this journey and have a chance at better health and simply better quality of life. I know there will be bumps in the road ahead, and everything won't be peaches and cream, but at least I have a great start so far. 😍

      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. 💗

      2. Doughgurl

        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. 💜
