Not hypoglycemia: Hypoglycemia is vanishingly rare. Symptoms include nervousness, sweating, hunger, anxiety, blurred vision, fatigue, fast heart rate, etc. -- however unless you have diabetes and are on Insulin or other medication, have renal or liver disease, cancer or prior stomach surgery -- then true hypoglycemia neveer occurs in human beings. If it a very frequently and incorrectly made diagnosis.
