Malnutrition? Help! (long)

Hi everyone. I haven't posted in quite a while.. life and all. But we've made it past the two year mark.. so I hope everyone is doing well. I've posted in the past about being a rather 'non-compliant' patient, which is nothing to brag about, but unfortunately, has continued. I do not follow post-op eating rules.. I can eat virtually anything, and I'm really only limited by the size of my stomach. I've taken to grazing and snacking.. and my meals center around carbs instead of protein. I likely don't drink enough fluids. I don't take vitamins. I don't exercise. I am a poster child for exactly what one SHOULDN'T do, as a post-op routine. I've felt pretty guilty, but lost a large percentage of weight and thought myself lucky that I was considered such a 'success' even while being so non-compliant. I wasn't experiencing any complications. In October of 2006, I was in a tanning salon and began to feel massively overheated, lightheaded, and like I was going to throw up or pass out. I ended up passing out, giving myself a concussion. I attributed it to overheating, or possibly low blood sugar as I hadn't eaten anything yet that morning. I went to the hospital, where they attributed it to the same thing, and did not wish to do labs to further investigate. Since then, that feeling has come over me several times. Extreme nausea, lightheadedness, shaky, sweaty, dizzy. Sometimes it's after I eat. Sometimes it happens if I haven't eaten in a while. Sometimes I've had plenty of fluids, sometimes I know I haven't drank enough. Occasionally it's when I'm taking a hot shower, but can also occur sitting in my freezing cold office. There seems to be no pattern. It was rather random, and would subside if I layed down for a while in a quiet, dark room. I only passed out the one time, but know that the other instances would lead to passing out had I not layed down immediately. The episodes were fairly spread out, so I wasn't really worrying. Now they're happening more often. A lot more. The soonest my doctor can have me in for blood tests is in two weeks. I'm freaking myself out here, waiting. I know it's my fault, and I'm willing to be accountable for doing this to myself. I'm beginning to be so overly conscious of 'how I feel' that I wonder if I'm not triggering the feeling by just thinking about feeling like that. I'm not sure if this could be a form of malnutrition, protein deficiency, vitamin deficiency, etc.. and I know i'll have to wait for labs to tell me for sure. I'm working on doing more of what I know I should have been all along. I'm trying. But does anyone have any insight on if my issues could be malnutrition? I just feel so guilty that some people push through all of these complications, do all the right things, and feel like crap. Here I sit, in a pattern of doing almost nothing I should, and I did this to myself. Thanks for reading.. I just had to get it out there.

I can feel like that when I haven't had enough water--for some reason I require LOTS of water. I even have a headache when I wake up in the am until I drink a glass of water. I'm glad you're getting back on track with suppliments and water. I hope your labs give you an answer. Let us know. Good luck.

you just described me in a nutshell! everything. here i sit, underweight, always in bed, now doing everything i should, but too late.man i wish i would have followed the rules. everything was too easy, no pre op testing, just approval and 6 weeks later, surgery. never followed the rules, just thought i was so lucky. now look at where it got me. i have been in the hospital a LOT for deh/malnutrition. whos laughing now huh? i praise you all who were rule followers and tell everyone i see to do it right the first time. i hope all your labs were normal. i hope hope hope your ok now. i have had all the same feelings as you and i pray your healthy.
