In brief: Low blood sugar

Cause jitteriness, severe anxiety, sweating, passing out, weakness, nausea vomiting, palpitations, and pallor. High blood sugar may not give any symptoms at all, or it may cause lethargy, altered mental status, speech problems, disorientation, abdominal pain and nausea vomiting as well.
The best way to recognize diabetes is to get a urine glucose and fasting blood glucose level.
