Two week liquid diet troubles



Recommended Posts

Hey everyone. I had a rough night on my 3rd night of my 2 week liquid diet. Been feeling good during the day but only getting around 360 calories a day and having trouble getting in all 64 oz of Water. Maybe that's why. I constantly have to get up to use the bathroom due to so much water intake. Last night around 3am I was wide awake. Went to bathroom then started to feel nervous and anxious. Then I became dizzy and hot so I went to the door to get some fresh, cool air and next thing I remember was my husband picking me up off the floor. I had fainted. I don't know if it's my nutrients, if I'm dehydrated, or something else. Maybe blood sugar. What did you eat during the day on the liquid diet and how much? I know I need to do at least 500 in my program, to shrink my liver. But I haven't been that hungry. Have you ever heard of anyone feeling that way and passing out? It's making me question all this. And if I will be able to get the nutrients and water I will need after surgery.

After I woke I was in a cold sweat but felt better. I drank a Protein Shake and more Water. I feel ok today. A little dizzy but not bad. And my head hurts from when I fell. Otherwise I think I'm ok so far. Going to try and take in more Protein and water today. I hope that's all it is. It just really scared me.

Sounds like you're dehydrated. When you feel dizzy or lightheaded, try eating a little salt or take a sip of regular Gatorade, not sugar-free. This is what I do (per my doc's recommendation) and it definitely helps.

The liquid diet makes me feel very light headed too. I am towards the end of.my second week, but walked to the park with my hubby and 3 year old son and nearly fainted. I would say that its either sodium levels or my body dealing with so little food. I came home and had a berocca performance and that set me straight. Be particularly careful when you wake up during the night and if you start to feel light headed get down on the floor and crawl back to bed if necessary. It might not stop you fainting, but it will stop the risk of injury from potentially falling into a door frame or onto the floor if you do faint.

@Okie75. Sorry you're having a hard time on the liquid diet. It sounds like you're not getting enough Protein. My surgery is scheduled for next Tuesday, May 30th. I started liquid diet on May 16th ( 6th day) and it's been amazingly easy.

I'm drinking at least 5 shakes and eating sugar free Snacks (e.g., pudding, Jell-O) or Dannon Light/ Fit Yogurt. I start drinking 6:30AM and end about 9:00PM. If I get hungry, I eat a Jell-O. As of yesterday, I'm down 7lbs. I'm drinking the Premier Protein (30g) or Atkins (15g).

Good luck!!

Thank you everyone! I was told 3rd day of liquid diet is hard. 3rd night is no joke either! I slept well the next night, doing great since. I've upped my Protein and try to have a sugar free popcicle or sugar free Jello every 2 hours or so and that helps. I think it was also my body saying, "What the heck!" I'm keeping an eye on my blood pressure as well. I really appreciate the comments. I knew it wouldn't be easy, but I had never passed out before, and that was scary. Thanks again!

I'm drinking a shake or eating every 2 to 3 hours so I won't get hungry. Ensure you DRINK the Water too. I'm in the restroom every 15 minutes! It's tiresome, but we HAVE to ensure no complications.

YOU CAN DO THIS! ASK GOD FOR STRENGTH. I'VE ALREADY SAID A PRAYER FOR YOUR STRENGTH. YOU CAN DO THIS!!

I'm on day 5 of my 7 day pre-op liquid diet and day 3 was absolutely the hardest for me. I've been weak more than anything. The Protein Shakes do seem to perk me up though so that helps. I also have been using peach tea crystal light in my Water to help me get the 100oz of water that my dr. requires. Hang in there! Every day I wake up and tell myself "I can do hard things" and aren't we all proving to ourselves and those around us exactly what we are made of?! This is a marathon not a sprint... Hang in there, you got this!

I started having dizzy spells when I was on liquids post surgery. My nutritionist had said Propel drinks were ok at this stage so I would drink at least a cup when I woke up in the mornings which helped. It's not a pleasant feeling but just make sure you're getting the recommended amounts of Protein and Water.

      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.
