Hypoglycemia in People Who Do Not Have Diabetes: Symptoms

Symptoms of both types resemble the symptoms that people with diabetes and hypoglycemia experience: hunger, nervousness, perspiration, shakiness, dizziness, light-headedness, sleepiness, confusion, difficulty speaking, and feeling anxious or weak.

If you are diagnosed with hypoglycemia, your doctor will try to find the cause by using laboratory tests to measure blood glucose, insulin, and other chemicals that play a part in the body's use of energy.
