pre op diet necessary?



Recommended Posts

I am sure BMI plays a part in deciding if you have to do a pre-op diet. As long as your doctor said you don't have to have one, then you are ok. I am not sure the exact guidelines. I will say this, if a doctor tells someone to follow a specific pre-op diet, it is to their advantage to follow it to the letter. The diet is done to shrink the liver to make it safer to move during surgery. There have been some that didn't follow their prescribed diet and woke up without their band. I know that doesn't apply to you since you have been told you didn't need one, but that is for any others that may read this who are required to do one.

I am a low BMIer of 37 and I'm still required to do the 14 day liquid diet... this is day 6! My doctor requires EVERYONE to do it. So, to be honest, I think maybe it just depends on the doctor. Scheduled for the 19th!

My BMI is in the 40's but I'm not on a pre-op diet. I just have to drink Clear liquids the day before surgery. I guess it depends on the Doctor.

The pre-op diet (as I understand it) is to help make your liver smaller so the surgeon can get to where he need to, easier.

I have no idea if a smaller BMI means a smaller liver, but I doubt it.

My surgeon requires it for everyone.

I am finishing day 3 of my liquid diet, as my surgeon also requires it of everyone regardless of BMI. The nurses at the office did however indicate that most people cheat and that they are really looking for a solid 10 days. Thus far it has been difficult but not unbearable. I am told the first 3 days are the toughest, I hope that's true. So far I have dropped 8 pounds in 3 days, but I have always lost quickly at the beginning of diets.

Is it true that depends on your BMI if you need to do the pre op diet? I was told I didnt need it.

I would say the truth lies in what your doctor wants for you. Many LBT posters were not required to do the pre-op diet even though they had a BMI over 40. Whereas, other LBT posters had to do a pre-op diet.

Really it is up to your doctor what she/he wants you to do.

Thanks for all your responses, I just looked at my paperwork and my BMI is 43.1 , i'm seeing Dr. Terry Simpson in Phoenix , AZ. He has great websites if you do a search he's all over the internet , I hd a consult with another Doctor and it just didn't feel right, Dr. Simpsons was total opposite. They did both say I ddn't need to do the pre-op diet though, even though a partient at work refered me to the other Dr. and she had to do the diet. Do you all think it might have to do with conditions people have? I'm thinking maybe it wouldn't hurt to just do it anyway??? What do you guys use as your liquids? My friend told me about some shake that her sister n law used before gastric bypass surgery , go to google and type in "all the whey". I'm getting a bit concerned about the vomiting and the bile coming up when people to to sleep. Im trying to prevent illness not get ill. I guess i'm trying to convince myself. I have an appt with my primary provider to get a referal letter for the insurance. Thats about all I need. Anyway all comments are greatly appreciated. Thanks! Sonya

I have no comorbities and BMI of 37 and still had to do my 2 week liquid diet. They told me like many others to shrink my liver and also stated that it would help out with the healing... high protein... not so bad that I'm on the downside of it now 4.5 days left on it! YIPPEE:lol:

I have the same BMI (43). My doctor suggests a low calorie diet 2-4 weeks in advance but only requires 2 days of liquid before the surgery. I was told that the pre-diet would not only help reduce the liver but it would also get your body prepared for life after surgery (which means 2 more weeks of liquid diet post-op).

My abdominal ultrasound a few months ago showed a fatty liver. I did the 2 week 800 calorie diet, lost 18 pounds then had surgery yesterday. My surgeon said my liver looked perfectly healthy, no fatty tissues at all.

For that reason, I think a pre-diet is a great thing. But I will be the first to say it wasn't easy. The first few days I felt like a drug addict in withdrawl. To make matters worse, I still had to cook meals for my three children and my husband. But I stuck to it and I am very happy with the results.

Can you please give me an idea of the types of things you ate on your pre op diet. My surgery is on the 23rd(next Fri) and I have been eating salads and drinking lots of Water and Protein Shakes. I had my preop today and found that I lost 8 lbs. I just don't want to find out that my liver hasn't shrunk enough to get banded. I'd be devastated. Only have 8 more days til surgery. Do you think its possible that my liver will have shrunk enough?

HeavensAngel1978,

I think it is definately possible to shrink your liver. This is how it was described to me. When you go on an 800 calorie diet, your body rebels. It can't survive on those calories alone so it takes the fat you have stored and burns it in place of extra calories. Even a few pounds of weight loss will help rid fat from the liver.

I did an 800 calorie diet with all liquids except for the addition of cottage cheese (I just needed something to chew). The two days before surgery however, I switched to pure liquids just as my doctor ordered. I experimented with several Protein Shakes (Bariatric Advantage and Atkins) but hated them. Then I discovered the Protein Drinks from costco called Premier Nutrition. These drinks became my lifesaver. They have 1 gram of sugar, 160 calories and 30 Protein. They actually taste pretty good too!

What I did was have one for Breakfast. One around 2:00p.m. and then another at 8:00 p.m. I actually wrote a thread a few days ago detailing exactly what I ate and at what times. Try clicking on my name and searching the post about a pre-op diet. If you can't find it write me back and I will detail it for you again.

I think you are off to a great start! 8 pounds in one week is excellent. I bet you have already shrunk your liver so keep at it. Also try walking as much as you can. I walked for at least 30 minutes every day during those two weeks. Keep up the great work.

My doc didnt need me to do it because i had a BMI of 35 and i had by chance had a liver ultrasound (my GP sent me for every test imaginable when he wrote my referral) and there was test results showing that I didnt have an enlarged or fatty liver.

DH had a BMI of 35 but knew he had a fatty liver (from previous testing) so he DID have to do it.

I was just lucky. If I hadnt had the liver ultrasound and liver enzyme tests, I would have had to do it.

I was told the pre-opt diet was to reduce the amount of fat around the liver. The amount of fat around this organ, can complicate the surgurial process.

      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!

        Life as a big person had limited my life to what I knew I could manage to do each day. That was eat. I hadn't anything else to look forward to. So my eating choices were the best I could dream up. I planned the cooking in managable lots in my head and filled my day with and around it.

        Now I have a whole new big, bigger, biggest, best days ever. I am out there with those skinny people doing stuff i could never have dreamt of. Food is now an after thought. It doesn't consume my day. I still enjoy the good home cooked food but I eat smaller portions. I leave food on my plate when I am full. I can no longer hear my mother's voice saying eat it all up, ther are starving children in Africa who would want that!

        I still cook for family feasts, I love cooking. I still do holidays but I have changed from the All inclusive drinking and eating everything everyday kind to Self catering accommodation. This gives me the choice of cooking or eating out as I choose. I rarely drink anymore as I usually travel alone now and I feel I need to keep aware of my surroundings.

        I don't know at what point my life expanded, was it when I lost 100 pounds? Was it when I left my walking stick at home ? Was it when I said yes to an outing instead of finding an excuse to stay home ? i look back at my last five years and wonder how loosing weight has made such a difference. Be ready to amaze yourself.

        BTW, the liquid diet sucks, one more day and you are over the worst. You can do it.
