I had NO clue this was something that could happen? I usually don't eat or drink anything sugary, and I cut down even more when I found out I was pregnant because I thought it was a healthy thing to do... apparently it was lowering my blood sugar far too much and affecting my nausea and appetite. I hadnt been able to get more than a few bites of food per day for two weeks and my weight loss got to critical. So the past few days I've upped my sugar intake and I have been RAVENOUS. I ate 3 whole meals today without feeling sick or being unable to finish a full portion. It feels so good! So I guess this is a PSA to anyone else with really bad nausea and no appetite, get your blood sugars checked!
