I hope everyone with these feelings is doing better. I have also had temporary "ill" feelings since my surgery, and I am 6 months post-op today. About 3 months ago I felt like I almost fainted while at work. I drank some water, but was really stressed about the feeling. I went to the ER for a precaution. To me it felt like my pacemaker quit on me. At the hospital they did blood tests, stroke tests, etc, but never found anything wrong and I was sent home about 4 hours later. I think I psyched myself out more after not feeling great.
A week later I started cardiac rehab and did a fasting blood test. I had a consult with the dietitien and she thought I may be reatcive hypoglycemic. This basically means by blood sugar can get lower after stresses, eg. execise, alcohol. poor diet, lack of sleep, too much caffeine, because my cells are slow to release sugar back to the blood. Symptoms of hypoglycemia are similar to what is described here. Since this finding I have eaten more frequently, and stayed away from high sugar foods. I think it might be helping. Once in a while I feel "off", but it usually passes after eating or resting. It's weird I didn't have this or notice it until after my OHS. I hope it goes away, but who knows. Has anyone else been treated for reatcive hypogymcemia?
