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.

ie

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.

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.

if they dont even have a real nutritionist- that would concern me that they are banding me.... just sayin.

Can someone just a good pre op high protein drink to fet other than slimfast?

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

Suggestions please.

Thanks, for sharing. But, can you drop a name brand?

Please

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:

I am doing optifast for my pre op diet...4 shakes a day and 1 chicken soup...It isn't too bad.....:thumbup:

when i have done slim fast in the past i would have a lot of bowel movements too

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.
