I am a 47 year old female. For the past 6 months, my periods have gotten much heavier...resulting in excessive blood loss in a short amount of time. In additon, my borderline hypoglycemia has gotten worse. Yesterday, (on the last day of my period) I became dizzy, my eyesight was affected, and I vomited. I know that low blood sugar can cause dizziness, confusion, low grade headaches, aggitation and can affect eyesight. But vomiting? That's a new one to me. I checked my temperature. It was 97 degrees (normal for me). I wonder if the extreme loss of blood due to my period has exaggerated my low blood sugar. Just a guess.
