Pre-op diet, WHY?



Recommended Posts

Maybe this is just me stuggling, BUT really why? My doctor has me on liquid and Protein drinks only for TWO weeks. She said it is to soften my liver and reduce the slick fat off of it to make it more pliable in surgery. How exactly does that work. Other people have said that it take alot longer than that for anything really to change in your liver. Is it not eatting solid food that FLUSHES the liver?? Is it not having carbs and sugar?

I know I am suppose to follow doctors orders to the letter, BUT if you are slipping is there better slips than others. Protien, real fruits or verggies??

I know the further into I get, MAYBE, it will get easier. That or as I get closer to surgery I will get more scared and loose my appitie. Well, a girl can hope:001_unsure:

It's my understanding that low carb is what they are after. You deplete your glycerin stores in the liver when you enter ketosis. One enters ketosis when one eats low carb.

If you need to eat more stick to Protein and fat.

By depleting the free blood sugar (which eating a low-carb diet does), you force the body to burn glycogen from your liver to keep you going.

Glycogen is stored bound to a lot of water; going low-carb causes your liver to shrink and become less "slippery" through, essentially, dehydrating it. This is very, very important before your surgery, so you must follow your doctor's advice to the letter. It may be hard, but it's only for two weeks, right?

You really do NOT want surgical complications (or, god forbid, liver damage) due to not following instructions.

If you're unwilling to follow the pre-op diet, you might want to reconsider the surgery. It might be difficult for you to live with how restricted your diet will be post-op.

Thanks for the explination. So far I am doing good. I am hoping it gets easier in time. I have 5 kids so I have to make food and be around it and it is a little hard for me to explain why all I am doing is drinking shakes.

I also am hoping that after surgery will be easier. I am guessing I really won't want to eat much. Really as of now I just want some grilled chicken. I do feel that now that I have three days under my belt I really don't want the carbs. I am hoping to break that hold, that and SUGAR.

I also want a BIG bowl of steamed brocolli.

Usually they have you on a pre-op diet for a while, and that is to lose some stomach and liver weight, so that when they blow up your tummy to get the instruments in, they have enough room to work, and the liver is lighter to lift.

Started my pre-op diet yesterday, I am having a hard time, I really want a sandwich! I'm doing the slimfast diet and already tired of sweet. Everything is sweet, except for dinner. I'm looking forward to that.

DO THE PRE-OP DIET!!!

I strayed off the path (big time), including splurging two nights before my surgery. In the end, the surgery took two hours, and they had to use so much gas (nitrogen, I think) to inflate my abdomen, that I've been feeling like I've had the bends ever since. I wouldn't wish this on the devil...

Today is the first day of my pre-op diet. So far so good. I totally get why it is necessary as the livers of people who are obese are generally VERY fatty. This can definitely cause problems during a laproscopic procedure. So...I'm with you! We can do it! I'm so excited about finally taking this step...I'd probably eat dirt if it was in my pre-op diet instructions! LOL! Have a great day!

Your original question was "BUT really why?"

Anatomically, the stomach is partially hidden by the liver, which must be retracted (pulled aside to get it out of the way) to access the stomach. The liver is a VERY dense, highly vascular organ. This means that if it is fatty, it is even more dense and difficult to retract. This increases the chance of rupturing or lacerating it interoperatively, which can be very serious, leading to hemorrhage and peritonitis. At the very least, as mentioned, it lengthens the surgery (adding more chance of complications related to anesthesia, clots, stroke, etc...). At the very very least, it's a pain in the ass to the whole surgical team, who are there trying to give you the best possible surgery. Stick to the pre-op diet that THEY give you (not us- i posted mine for those who were never given one). It will make your liver smaller, floppier, and easier to deal with in the OR. This is not a root canal. It's major abdominal surgery.

If you have questions, ASK them of your doctor. If you don't understand the answer, ASK again, and ask her to EXPLAIN them until you understand them. Don't let them rush you or discourage you from asking. This is YOUR body and YOUR life. There is a reason that you sign an "informed" consent. Your doc is legally, professionally, and ethically obligated to make sure you are fully informed, but only you can determine if you understand everything. Speak up, and good luck!

Thanks for this info. It will certainly give me all the more inspiration when I go through the pre-op withdrawals. I will just keep a mental picture of a "floppy" liver in my mind and will not go near any baddo foods.

In the obese, the liver is a huge, fatty organ. It is ?in the way? of the surgical area during band surgery, and must be held back with surgical instruments. An enlarged liver is very fragile and bleeds quite easily when touched or manipulated during surgery. This bleeding can be difficult to control, and the extra care required with an enlarged liver increases surgical risk, as well as surgical time. Longer surgical time and extended time under general anesthesia can make both immediate and longer-term recovery much more difficult for you. An especially large and fragile liver has even caused some surgeries to be cancelled, for the safety of the patient.

Following this Pre-Op Diet is extremely important. The goal is not to lose weight, necessarily, but to enter a temporary period of dietary ketosis, which is not harmful to you at all. However, many do lose a good amount of weight, which will jump-start your weight loss as you begin to regain and improve your health. It is this dietary ketosis that results in liver-shrinking and the normalizing of your metabolism so that you can do well with.

WOW!!. I will be honest - I was not put on a preop diet except for after midnight the day before surgery. I even went out and had a large plate of Pasta that Monday night (Wed AM surgery). I read the boards that Tues and really got scared with all the stories of 2 week pre op diets and liver size. I asked my doc the morning of surgery do we need to delay and he said it was no big deal.

Guess what I am saying is go with what your surgeon says but if you slip - its not the end of the world.

I didn't have a pre-op diet either. But maybe my liver wasn't too big and my surgeon could cope with it!

I had a 2 week pre-op diet but was allowed an Atkins type dinner. It wasn't all liquids until the day before surgery. Every surgeon is different. My surgery went very well, no complications so his method evidently works, and I lost 18 lbs pre-op. I asked him post op about my liver and he said it was "small and healthy".

      So I guess after gastric bypass surgery, I cant eat flock chips because they are fried???  They sell them on here so I thought I could have them. So high in protein and no carbs.  They don't bother me at all.  Help.

        It's possible for a very high fat meal to cause dumping in some (30% or so) gastric bypass patients, although it's more likely to be triggered by high sugar, or by the high fat/high sugar combo (think ice cream, donuts). Dietitians will tell you to never do anything that isn't 100% healthy ever again. Realistically, you should aim for a good balance of protein, carbs, and fat each day. Should you eat fried foods every day? No. Is it possible they will make you sick? Maybe. Is it okay to eat some to see what happens and have them for a treat every now and again? Yes.

      I'm not at all hungry on this liquid pre-op diet, but I miss the sensation of chewing. It's been about two weeks––surgery is in two days––and I can't imagine how I'll feel a couple of weeks post-op. Tonight, I randomly stumbled upon a mukbang channel on YouTube, and it was strangely soothing... is it just me, or is this a thing?

        I actually watched cooking shows during my pre-op, like Great British Baking Show. It was a little bizarre, but didn't make me hungry. I think it was also soothing in a way.

      How do you figure out what your ideal weight should be? I've had a figure in my head for years, but after 3 mths of recovery I'm already almost there. So maybe my goal should be lower?

        Well, there is actually a formula for "Ideal Body Weight" and you can use a calculator to figure it out for you. This one also does an adjusted weight for a person who starts out overweight or obese. https://www.mdcalc.com/calc/68/ideal-body-weight-adjusted-body-weight

        I would use that as a starting point, and then just see how you feel as you lose. How you look and feel is more important than a number.

      2. Clueless_girl

        I did find different calculators but I couldn't find any that accounted for body frame. But you're right, it is just a number. It was just disheartening to see that although I lost 60% of my excess weight, it's still not in the "normal/healthy" range..

      Tomorrow marks two weeks since surgery day and while I'm feeling remarkably well and going about just about every normal activity, I did wind up with a surface abscess on on of my incision sights and was put on an antibiotic that made me so impacted that it took me more than two hours to eliminate yesterday and scared the hell out of me. Now there's Miralax in all my beverages that aren't Smooth Move tea. I cannot experience that again. I shouldn't have to take Ativan to go to the lady's. I really looking forward to my body getting with the program again. 
      I'm in day three of the "puree" stage of eating and despite the strange textures, all of the savory flavors seem decadent. 
      I timed this surgery so that I'd be recovering during my spring break. That was a good plan. Today is a state holiday and the final day of break. I feel really strong to return to school tomorrow.

      Now that I'm in maintenance mode, I'm getting a into a routine for my meals. Every day, I start out with 8-16 ounces of water, and then a proffee, which I have come to look forward to even the night before. My proffees are simply a black coffee with a protein powder added. There are three products that I cycle through: Premier Vanilla, Orgain Vanilla, and Dymatize Vanilla.
      For second breakfast on workdays, I will have a low-fat yogurt with two tablespoons of PBFit and two teaspoons of no sugar added dried cherries. I will have ingested 35-45 grams of protein at this point between the two breakfasts, with 250-285 calories, and about 20 carbs.
      For second breakfast on non-workdays, I will prepare two servings of plain, instant oatmeal with a tablespoon of an olive oil-based spread. This means I will have had 34 grams of protein, 365 calories, and 38 carbs. Non-workdays are when I am being very active with training sessions, so I allow myself more carbohydrate fuel.
      Snacks on any day are always mixed nuts, even when I am travelling. I will have 0.2 cups of a blend that I make myself. It consists of dry roasted peanuts, cashews, pumpkin seeds, sunflower seeds, pistachios, and Brazil nuts. This is 5 grams of protein, 163 calories, and 7 carbs.
      Breakfast and snacks have been the easiest to nail down. Lunch and dinner have more variables, and I prepare enough for leftovers. I concentrate on protein first, and then add vegetables. Typically tempeh, tofu, or Field Roast products with roasted or sautéed vegetables. Today, I will be eating leftovers from last night. Two ounces of tempeh with four ounces of roasted vegetables that consist of red and yellow sweet peppers, sweet potatoes, small purple potatoes, zucchini, and carrots. I will add a tablespoon of olive oil-based spread, break up 3 walnuts to sprinkle of top, and garnish with two tablespoons of grated Parmesan cheese. This particular meal will be 19 grams of protein, 377 calories, and 28 grams of carbs. Bear in mind that I do eat more carbs when I am not working, and I focus on ingesting healthy carbs instead of breads/crackers/chips/crisps.
      It's a helluva journey and I'm thankful to be on it!
