The goal is to consume 10-20 grams of a carbohydrate to raise blood glucose levels to a minimum of 70 mg/dL (3.9 mmol/L).Examples of products to consume are:

Glucose tabs or gel (refer to instructions on packet)
Juice containing sugar like apple, grape, or cranberry juice, 4 ounces or 1/2 cup
Soda or a soft-drink, 4 ounces or 1/2 cup (not diet soda)
Candy
Table sugar or honey, 1 tablespoonImprovement in blood sugar levels and symptoms are expected to occur in 15–20 minutes, at which point blood sugar should be measured again. If the repeat blood sugar level is not above 70 mg/dL (3.9 mmol/L), consume another 10-20 grams of a carbohydrate and remeasure blood sugar levels after 15–20 minutes. Repeat until blood glucose levels have returned to normal levels. The greatest improvements in blood glucose will be seen if the carbohydrate chewed or drunk, and then swallowed. This results in the greatest bioavaliablity of glucose, meaning the greatest amount of glucose enters the body producing the best possible improvements in blood glucose levels. The second best way to consume a carbohydrate it to allow it to dissolve under the tongue, also referred to as sublingual administration. For example, a hard candy can be dissolved under the tongue, however the best improvements in blood glucose will occur if the hard candy is chewed and crushed, then swallowed.After correcting blood glucose levels, people may consume a full meal within one hour in order to replenish glycogen stores.
In some, the hypoglycemic episode may be reproduced simply after a mixed meal, whereas in others a fast may last up to 72 hours.In those with a suspected insulinoma, imaging is the most reliable diagnostic technique, including ultrasound, computed tomography imaging (also called CT imaging), and magnetic resonsance imaging (also called MRI). Treatment
After hypoglycemia in a person is identified, rapid treatment is necessary and can be life-saving. The main goal of treatment is to raise blood glucose back to normal levels, which is done through various ways of administering glucose, depending on the severity of the hypoglycemia, what is on-hand to treat, and who is administering the treatment. A general rule used by the American Diabetes Association is the "15-15 Rule," which suggests consuming or administering 15 grams of a carbohydrate, followed by a 15-minute wait and re-measurement of blood glucose level to assess if blood glucose has returned to normal levels. Self-treatment
If an individual recognizes the symptoms of hypoglycemia coming on, blood sugar should promptly be measured, and a sugary food or drink should be consumed. The person must be conscious and able to swallow.
