Hi- I was just wondering if anyone else has experienced this. Twice now I have passed out. I have narrowed it down in my head to dehydration. Both days that this happened was on a Saturday and on the weekends sometimes I forget to drink my Water like I should. I have talked to my doctor about this but she said she hasnt seen this be common in post surgery patients and referred me to a neurologist but just interested if anyone else has experienced this.

Thanks!!

Could be low blood sugar, too. I have had that happen with low carb.

Last August, at my 9 month mark, I got really sick with something or another and was sick all day and through the night. After my third explosive (both ends) trip to the bathroom, I did not make it back out. I passed out and hit my head on the bathtub (about 1:30 in the morning, and was out for an hour). I finally woke up and tried to call my man, but the bathroom door was shut, the bedroom door was shut, and the window air conditioner was on. My voice was faint because I was weak, and he could not hear me.

I tried to get up and passed out a second time....hitting my head on the bathtub a second time, and was out about an hour and a half. At about 4:00, I came around again and finally stumbled my way to bed. I fell asleep and did not wake up until he had already gone to work. Sparing some other details and scoldings from my daughters and doctors, I ended up in the ER with an overnight stay for fluids. They were sure it was dehydration, but I had to wear a heart monitor for 30 days.

Lessons learned: Try not to get dehydrated.

Don't lay down and go to sleep afeter a concussion, let alone two.

Call the doctor or 911 instead of waiting three days.

Don't take passing out lightly. There was a guy on the forum a while back who passed out and busted his jaw.

Yup this happened to me in he beginning. I started drinking Gatorade so I could keep my blood sugar up and stay hydrated. It made a huge difference in how I felt.

I'm still pre-op but I have always been prone to fainting. Because of my size people always assume I'm diabetic, but it's actually due to low blood pressure. If I'm dehydrated at all or miss a meal, down I can go. Stay hydrated and be mindful of not standing up too fast. Those two things have really helped me!

Electrolytes! Get G2. Nothing wrong with your head or nervous system. Lol

If you get too dehydrated, see your surgeon. I am sure the hospital can pymp you up with one iv sitting.

I've never had diabetes or sugar issues but was sleeved on 12/12 and they came in at 4am to draw my blood. They got the results and my blood sugar was low, it was 60. The nurse told me this is very rare and they don't see it often. She asked me if I felt dizzy/light headed and I said a bit. She came in with this humongous syringe and I asked her where she was putting that & she said in my IV...they put in way too much and spiked my sugars at 190. I got released once they got them under control. My dad, who is an MD told me I can't have everything sugar free...he had me drink a little orange juice diluted with ice chips/water when I was home...or a G2 Gatorade. I asked my doctor if this would be an issue in the long run, he told me we'd draw labs on 2/25 when I come back & see how I was doing. As for now I always have a G2 Gatorade in my purse and a pack of lifesavers, just in case!

Another possibility to keep in mind, especially if the "almost passing out" comes right after you stand up, is orthostatic hypotension. A fair number of post-wls patients get this condition due to the rapid drop in blood pressure after surgery.

It happened to me after surgery. I ended up in the ER and there was nothing wrong with me. Come to find out, I was not eating enough calories. It stopped when I increased my intake.

I also am fainting while waiting for a table at a restaurant. Tonight was the second time for me too. Will check with doctor on Monday. Thanks for all the ideas, feeling like I'm not alone in this is nice. ☺️

Well, I went to the doctors today. My blood pressure was 82/56, which is kinda low. She gave me and EKG and took my blood pressure laying down, sitting and standing and it was doing the opposite of what it was suppose to do. When it came down to it she said I need to drink the 64 oz of Water and eat a little more salt. I was slacking on my Water in take. She's sending me for an EEG just to make sure I didnt have a seizure because when I passed out, both times I urinated on myself. Super embarrassing. But for the most part I have to drink more water. Thanks for all the replies!!!

      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.
