Prevention
Diabetics
The prevention of hypoglycemia depends on the cause. In those with diabetes treated by insulin, glinides, or sulfonylurea, the prevention of hypoglycemia has a large focus on patient education and medication adjustments. The foundation of diabetes education is learning how to recognize the signs and symptoms of hypoglycemia, as well as learning how to act quickly to prevent worsening of an episode. Another cornerstone of prevention is strong self-monitoring of blood glucose, with consistent and frequent measurements. Research has shown that patients with type 1 diabetes who use continuous glucose monitoring systems with insulin pumps significantly improve blood glucose control. Insulin pumps help to prevent high glucose spikes, and help prevent inappropriate insulin dosing. Continuous glucose monitors can sound alarms when blood glucose is too low or too high, especially helping those with nocturnal hypoglycemia or hypoglycemic unawareness. In terms of medication adjustments, medication doses and timing can be adjusted in order to prevent hypoglycemia, or a medication can be stopped altogether. Non-diabetics
In those with hypoglycemia who do not have diabetes, there are a number of preventative measures dependent on the cause. Hypoglycemia caused by hormonal dysfunction like lack of cortisol in Addisons disease or lack of growth hormone in hypopituitarism can be prevented with appropriate hormone replacement. The hypoglycemic episodes associated with non-B cell tumors can be decreased following surgical removal of the tumor, as well as following radiotherapy or chemotherapy to reduce the size of the tumor.
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.
