blood sugars low
I am preop but don't always eat often enough. When my sugar gets below 70 I start feeling pretty bad. Around 55 it's dizzy time. But even if I don't feel hungry (which I sometimes don't due to meds) I will start feeling nauseous before the big dip below 70. Is your body sending you any alternate "feed me" messages besides active hunger? It took me awhile to figure out the nausea.
