Pre-Op Diet And Blood Glucose Levels



Recommended Posts

I was just diagnosed with type 2 diabetes a week and a half ago. Started my pre-op diet last Wednesday (2 Meal Replacement shakes and sensible meal.) Nutritionist and doctor said that most people see a big reduction in their glucose levels and some even go off their meds during the diet. Mine are still high. :( Anyone else have similar situation?

The nurse practitioner even told me to stop the metformin now due to a bleeding risk during surgery. (?) Seems odd, never heard that about metformin before.

Define high. What is your fasting blood sugar on average?

I'm off my Metformin too as well as most of the others. My fasting blood sugar is up from it's usual 125 to 145. Not panic time but definitely noticeable.

Around 315. This AM it was 360. I am following the diet to the letter (getting the no-sugar added shakes), not cheating, taking my metformin 2x a day. My levels generally get lower during the day, down into the mid 200-s. I did record a couple at 190 this weekend in the evening. I've only been testing about a week. And on the metformin for 1.5 weeks.

Of course, my levels could have been CRAZY high before I was diagnosed and they may actually be coming down. But, it just doesn't seem like that's happening. :(

I'm not sure if I have the same problem since I don't have a meter but I'm having a difficult time with the diet. I'm insulin resistant and had to stop my metformin in preparation for the surgery but I'm struggling with extremely low energy at the moment. The lack of metformin combined with a low carb, low calorie pre-op diet is painful for me. My bones actually hurt from the lack of energy. This has a lot to do with why I gained so much weight to begin with. I have extremely low energy and, therefore, difficulty functioning when I eat low carb and/or low calorie diets which in turns causes me to want to carb up for energy which in turn causes me to gain weight. It is a vicious cycle. I'm really hoping that the surgery helps me to overcome it although I am really struggling with the pre-op diet at the moment.

That's pretty high. They should have given you instructions about what numbers they are looking for and when to contact them. It probably wouldn't hurt to give the doctor a call and go over your blood sugar log so they can make a decision about how it should be handled. There are lots of medications besides Metformin they can use for treatment.

It's also possible that they're willing to go with the high numbers because they know the procedure is going to very soon and they'll come down once it happens. It can't hurt to call to let them know what's going on.

You are getting this done at the right time. I've been treating diabetes for 7 years and it's a losing battle. If I had gotten WLS sooner I would have saved myself a lot of discomfort and aggravation.

Thank you. I have my pre-op appointment with my surgeon this afternoon. I plan to ask him. I also have an appointment with my PCP (who diagnosed the diabetes) tomorrow AM. I'm definitely hoping for more guidance. The high numbers are scaring me.

I'm also concerned he won't do the surgery if my levels are this high. Hopefully an unfounded worry, but I'm an expert worrier!

Bring your blood sugar log to your appointments as well as your food log. Your doctor can compare what you are eating to your blood sugar numbers and try to see if there is something specific that needs to be changed.

Good luck!

      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. 💗

      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.
