An insulin pump used to deliver appropriate levels of insulin. 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 consistnent 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 Addison's 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. In some cases, those with non-B cell tumors may have hormone therapy with growth hormone, glucocorticoid, or octreotide to also lessen hypoglycemic episodes. Post-gastric bypass hypoglycemia can be prevented by eating smaller, more frequent meals, avoiding sugar-filled foods, as well as medical treatment with an alpha-glucosidase inhibitor, diazoxide, or octreotide. Some causes of hypoglycemia require treatment of the underlying cause to best prevent hypoglycemia. This is the case for insulinomas which often require surgical removal of the tumor in order for hypoglycemia to remit. In patients who cannot undergo surgery for removal of the insulinoma, diazoxide or octreotide may be used.
