Why would I feel so lightheaded & nauseated after working out?



Recommended Posts

I worked out at Shapes today for the first time. I only did 15 mins stationary bike, 5 mins elliptical, and 5 mins on another cardio machine like a "skiing" motion, no clue what its called. Anyway, I felt great after I was done until about 15 mins or so after leaving while I was driving, I suddenly felt really dizzy & sick to my stomach. I had to pull over & blast my a/c on my face for a few mins till it passed & I was able to drive again. It was scary, I thought I was gonna wreck my car cuz even my vision got blurry when I got dizzy. It came on so fast, no warning at all. What would cause this? My heartrate never got above 140 according to the machines??

Sounds like your blood sugar bottomed out. I get dizzy, shaky, light-headed, sweaty, and just all-around YUCKY when my blood sugar takes a dive, and it can happen soon after a workout.

Are you diabetic by any chance?

WHat had you eaten? Could you just have had no fuel in the tank? The thing is with a lapband it doesnt make your body work any differently. Your body still has the same energy needs, the band just helps you manage hunger.

A small snack before or just after your workout might make a difference.

I am diabetic, my sugars are usually super high like 250-300 even on meds. (glyburide, no insulin) Maybe thats what it was, I have never felt that way before. I am not banded yet, will be on the 11th. All I had before I went was a Protein Shake. Tomorrow I will eat a lean pocket or something & see if that helps. It was so strange to go from feeling so great to so sick in just a few mins.

If it happens again, be sure to check your blood sugar to see if you're low. I'm betting that's what it was. When it happens to me it's comes on very fast, so I usually suck on a couple of pieces of hard candy (just enough to get my sugar level coming back up) and then try to find some Protein to eat in a hurry. That keeps it from crashing again. String cheese is great for this, or Peanut Butter, but I find that there is too much sugar in peanut butter, and not enough protein to keep my sugar level stable. Cottage cheese is another good one for this.

I have to have "fuel" before a workout - otherwise I crash FAST. I typically hit the gym about 40mins after Breakfast - of which I make sure it's not a "protein shake"...For me that's not what works in getting in some hard cardio - I have to have real food. My Doc suggests to keep raw almonds or ostrich Jerky (haven't tried that one yet) with me at all times - Good to pop in right afterwards if I'm STARVED, ... Usually ties me over till lunch.< /p>

It's great your getting a jump start on exercising before the Band - !!

      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.

        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.

      Three months and four days ago... I was in Costa Rica having a life changing surgery! Yesterday we had a followup visit with Dr. Esmeral via video chat and this morning my middle number changed.  I'm down 47lbs and two pants sizes. I can wear a Large tshirt for the first time in like... 14 years! Woot!! Everything is going great. I have zero regrets. I went down to the riverwalk with a friend and walked 2 miles on Monday without even getting fatigued. And no more snoring or chugging pickle juice for crazy leg cramps! I need to go to the gym more... I'm making new shirts next week so that will motivate me. LOL But I'm also just not as TIRED all the time! I have a LONG way to go...but seeing the progress on the scales and in the mirror is a huge motivator!! Thank you all for cheering me on and supporting me!!
