Weak and lightheaded



Recommended Posts

Almost every day for the past week I've been getting really weak and light headed like I'm going to pass out. The only thing that helps me is to eat something which leads me to believe that my blood sugar levels are low. I'm not sure what is causing this. Has anyone experienced this before? I'm 4 months post op by the way.

Do you have access to a glucometer to check your blood sugar when it happens?

Probably I'm 10 weeks out did everything I should. Dr wanted me to lower my carb intake just a bit. Yesterday I did. Had my light Protein shake for Breakfast 4:30am then snack at 10am. lunch was tuna around 12 and a p3 which is turkey, cheese and nuts at 3. Took a nap got up had salad w grilled chicken around 6. Headache most of the day. My bs was 40 then 34 then registered low. Finally got it back up. Needless to say I am sticking with the carbs I was on. It was working for me.

Dehydration or not enough calories usually causes those symptoms for me.

When I feel like that I stop what I'm doing, get a couple bites of something then start a bottle of Water.

I don't know about you, but for me it can sometimes be 3:pm and I realized I have have had maybe 100 calories for the day. I get busy and forgetful, causing that weakness and lightheadedness.

Yes. This did happen to me early on and occasionally still happens. My doctor and I found out it was when I had not eaten enough. So I started eating every 4-5 hours and that helped "cure" it. My doctor said because I'd been insulin resistant for so many years my sugar was bottoming out even though my blood work and A1C were normal.

If I get out of my routine or do something extremely physical without eating I almost pass out. I try to eat the same times every day so my body knows it will get a steady source of calories. I don't mean grazing either. I mean planned out meals or Snacks that fit within your calorie and Protein requirements. I also always carry an emergency snack with me. Protein Bars or Jerky in my purse, glovebox and desk drawer.

Hope this helps! It can be scary.

I forgot to mention to you that I also had an issue with severe fatigue for 3-4 months after surgery and I took my MFP food logs to my doctor and told him I could barely get through work and was tired all the time. He took one look and said I was eating too low carb. He told me to add fruit back into my diet (I was avoiding any and all sugar). So I started to eat a banana or apple every day and the issue completely resolved itself. Carbs are important! This was a separate issue from the passing/blacking out issue. I still deal with that occasionally but it is from lack of calories, not carbs.

My primary dr is the one who wanted me to lower the carb intake. I had been doing about 40-60. Since I'm off all my meds including diabetic ones she previously prescribed. Bypass nurse said since my body is readjusting to insulin and not being as resistant, I need some carbs. Obviously nurse was right the only other time this has happened since surgery was thanksgiving, but not near as low. We waited too long to eat and we also went on a walk. Definitely gotta keep it in check. Before a piece of fruit flavored candy is the only thing I found that would help. Not any more so I have to relearn my body. I missed 3rd shift last night and when I went by the office today was told I looked pale and sick. They have never said that before.

      Day 1 of pre-op liquid diet (3 weeks) and I'm having a hard time already. I feel hungry and just want to eat. I got the protein and supplements recommend by my program and having a hard time getting 1 down. My doctor / nutritionist has me on the following:
      1 protein shake (bariatric advantage chocolate) with 8 oz of fat free milk 1 snack = 1 unjury protein shake (root beer) 1 protein shake (bariatric advantage orange cream) 1 snack = 1 unjury protein bar 1 protein shake (bariatric advantace orange cream or chocolate) 1 snack = 1 unjury protein soup (chicken) 3 servings of sugar free jello and popsicles throughout the day. 64 oz of water (I have flavor packets). Hot tea and coffee with splenda has been approved as well. Does anyone recommend anything for the next 3 weeks?

        All I can tell you is that for me, it got easier after the first week. The hunger pains got less intense and I kind of got used to it and gave up torturing myself by thinking about food. But if you can, get anything tempting out of the house and avoid being around people who are eating. I sent my kids to my parents' house for two weeks so I wouldn't have to prepare meals I couldn't eat. After surgery, the hunger was totally gone.

      I have my final approval from my insurance, only thing holding up things is one last x-ray needed, which I have scheduled for the fourth of next month, which is my birthday.
