Reactive Hypoglycemia After Bariatric Surgery



Recommended Posts

Hi;

I have not read about this topic on here and so I thought I would share my latest health issue. I found this article on it and thought others might find it interesting because it does happen to WLS patients more then you think!

What is reactive hypoglycemia?
After bariatric surgery you may experience reactive hypoglycemia:
• Hypoglycemia means low blood sugar
• Reactive hypoglycemia is having low blood sugar after eating a
meal or snack
This may happen after eating foods that are high in sugar or simple
carbohydrates. It is thought to be related to dumping syndrome.
How do I know if I have reactive hypoglycemia?
You have reactive hypoglycemia if you have:
• any symptoms listed below a few hours after having a meal or
snack and
• these symptoms go away after eating or drinking
What are the symptoms of reactive hypoglycemia?
You may feel one or more of these:
• hungry • sweaty
• shaky • anxious
• dizzy • weak
• sleepy • confused
What should I do if I think I have reactive hypoglycemia after having
a meal or snack?
Having low blood sugar is not good for your overall health and can be
life-threatening.
• If you think you have reactive hypoglycemia, check your blood
sugar.
• If your blood sugar is less than 4 mmol/L, you need to treat it to
bring your sugar above 4 mmol/LWhat is reactive hypoglycemia?

Having low blood sugar is not good for your overall health and can be

• If you think you have reactive hypoglycemia, check your blood
sugar.
• If your blood sugar is less than 4 mmol/L, you need to treat it to
bring your sugar above 4 mmol/L. Follow the steps on the next
page.
If you do not have a meter, talk to your family doctor, health care
provider or the diabetes educator in the Bariatric Clinic to get a meter.
When your blood sugar is less than 4 mmol/L:
1. Take 15 grams of a fast acting carbohydrate right away.
This will raise your blood sugar quickly.
Examples of fast acting carbohydrate include:
• Chewing 3 to 4 dextrose or glucose tablets (read the label)
or
• Drinking ¾ cup (175 ml) of juice
2. Wait 15 minutes and check your blood sugar again.
3. If your blood sugar is still below 4 mmol/L treat again with one of
the fast acting carbohydrates listed above.
4. Repeat these steps until your blood sugar is above 4 mmol/L.
5. If your next meal or snack is more than 1 hour away, you need to
have a snack that contains carbohydrate and Protein that fits
into the stage of diet you are at. Examples of Snacks are listed
on the last page.
You may feel like eating sweet foods like Cookies, cake and candy.
Even though these foods are high in sugar and can raise your blood
sugar, your blood sugar will go too high too fast which is not safe. This
can then lead to another low blood sugar because too much insulin is
released.
How can I prevent reactive hypoglycemia?
You can help prevent reactive hypoglycemia by following your diet
guidelines for bariatric surgery.
• eat 3 healthy meals and 2 healthy Snacks each day
• space meals and snacks 2 to 3 hours apart
• eat Protein at each meal and snack time
• avoid skipping meals andsnacks
• avoid or limit alcohol depending on what stage of diet your are at
• avoid or limit caffeine depending on what stage of diet your are at
• avoid sweets like Cookies, cakes, candy, pop, juice and sweet
drinks
Instead of sugars and simple carbohydrates, eat complex
carbohydrates because they release less sugar over a longer period of
time. Having a complex carbohydrate with protein will slow this release
even more.
Try putting any of these together when they fit the stage of
bariatric diet you are at:
Complex Carbohydrates
• whole wheat crackers
• whole wheat bread
• whole wheat pita
• whole grain rice
• potatoes
Cereal
Protein
• nuts
cheese
meat
• lentils
eggs
• yogurt
Here are some snack ideas to have after treating
a low blood sugar:
• crackers and cheese
• pita and hummus
• nuts and yogurt
melba toast and Peanut Butter

Luckily, if we are eating as we should, this shouldn't be an issue.

Yes I became hypoglycemic after surgery. Its not about eating sweets. None of us can eat enough to sustain our blood sugar levels which cause this issue. I find eating every couple of hours has solved my problem. If I don't then you can find me on the floor. I got smart really quick after the first episode and that my blood work from my doctor my blood sugar was 40 after eating a complete meal. That is another reason Protein is important to all of us.

... Put down that cupcake...

It has nothing to do with cup cakes. It has to do with not being able to put enough complex carbs in your sleeve sometimes to make things work properly. One thing my nut told me is that if you had it before in the past it can rear its ugly head again after surgery.

I started having this when I began training ( exercising ). I had no idea that it would happen to me. Every other issue seems to have leveled itself out. But this one came on hard and fast.

So now Like @@cheryl2586 I have to eat something 6 times a day. the episode I had last was so bad I passed out. Scared the S**T out of me.

My nut told me that it does not happen to everyone but some. Yes it can. I like others are informing that this is a possibility!

Cupcake indeed!

I'm a type one diabetic and I balance what I eat to keep my sugar from dropping. Sometimes in uncontrollable and ill drop after eating about an hour later. I have to eat every 4 hours or so to keep this from happening. I'm almost two years post vsg

I'm a type I diabetic too, and since I have to take insulin, my hypoglycemia is usually a miscalculation on the amount of insulin I need to take. (75% less than I used to take) If I bolus for Snacks, I usually experience a mind-shattering low. So I am learning to cut my insulin more and more. Pretty soon I will be taking far less than a diabetic baby. Go figure!

yup, i had this when i was pregnant. i highly recommend getting a blood sugar monitor to check blood glucose levels before and after eating and exercise to see how food and exercise affects you. it's different for everyone. some people get high surges and then drops. some people are only reactive to high GI foods, so people are reactive to not eating enough carbs, some people have sudden drops whenever they eat. if you track your BGL you will be able to more easily treat it.

I have never had Hypoglycemia before nor have I ever been Diabetic. I have previously been diagnosed as insulin resistant but since my sleeve surgery a year ago I have recently developed the symptoms and have had a number of scary 'hypo' episodes when commencing exercise especially in the morning. This is causing me great concern, I didn't sign up for this surgery to become sicker than I was before it. I hope I can get some help on how to manage the symptoms as from what I've read up about, many bariatric patients end up developing reactive hypoglycaemia which I had no idea about until I started getting the symptoms. Does anyone know how best to deal with this? I want to be able to exercise but for the last few weeks I've been unable to manage much before the sweats, the shakes, and feeling like I'm going to pass out, and worse I want to eat!! My weightloss is at a stall, nearly 2 months and no change. Would appreciate any guidance.

Please also be aware that this problem occurs to many many Bariatric patients quite often some time after their surgery and from what I've read there is no cure, just guidelines to manage it. Essentially though our Pancreas are delivering too much insulin into our bodies which is what causes the hypo. I'm seeing my surgeon next week for my 1 year review and my GP next week for bloods to see if there is any help I can get for this condition.

what is your blood glucose level in the morning? you need to know this and then how to bring it up to normal level before starting exercising. how you treat it will depend on how low it is in the morning.

It is one of the scariest things I have had to deal with so far..And I have had some dillies. So far I have been managing it not to badly...But the symptoms come on so fast...It rocks everything I am doing...Don't want to have one with my grand daughter in the car while I am driving or when I am baby sitting her. Very unsettling....

I have no idea what my blood glucose levels are as I have no way of checking as have no monitor? I'm hoping my GP will be able to do some bloods and give me some help with this as it really is so debilitating and ruins my entire day even after the initial symptoms have finished I still feel terrible for hours after.

Worse news is my surgeon's office have just cancelled my 1 year review appointment next week as he has an urgent surgery to do and will reschedule me for some time in the future but when I told them about this new condition they suggested I make an appointment with the team dietician. I really do want a medical opinion too though so still seeing GP next week but their knowledge of this surgery isn't great from what I've experienced so far they just constantly refer to guidelines they have about Gastric Bypass.

It is scary instant it RJ? I really can't bear the thought of this being a long term complication of the sleeve and hope we can get some real help and advice on how to manage it. As you say if it happens in a public place or behind the wheel it's awful.

you have to ask your doctor to write a script for a monitor so you can start checking your BGL. usually the pharmacy has coupons that make the monitor free and insurance covers the strips. if you start checking your BGL several times a day (first thing in the morning, 1 hour, 2 hours, 3 hours after a meal and before bed) you will get an idea of how food affects you and if eating before bed helps how you feel in the morning. i had this issue when pregnant, my GBL was really low in the morning and i would fall over while doing yoga... i learned i needed to eat more carbs than i thought in order to get my level up to normal.

this is not reactive hypoglycemia, its different. the only way for you to know what is actually happening with you is to check with a monitor for a few weeks. good luck!

      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. 💗

      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. 💜

      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.
