How is hypoglycemia diagnosed medically?

Serum glucose: Hypoglycemia simply means low glucose. So, the diagnosis is made by taking a blood sample and measuring the blood glucose level (mg/dl). Generally, a level below 70-90 is low but this all depends on the individual and their medical issues. Hypoglycemia can be caused by a number of things but is often associated with uncontrolled diabetes. However, many other causes exist.

Blood tests: It can be diagnosed by a fingerstick test, or a regular blood test. Some people feel the symptoms of hypoglycemia even if the glucose is normal. This is usually when the glucose level is dropping quickly. It is fairly common to feel this way when beginning treatment for diabetes, even if the medication cannot cause the glucose to be below normal.
