Hypoglycemia. Pathophysiology and treatment.

Hypoglycemia is a common consequence of many diabetes treatments. As is true for many therapies for diseases with major pathologic consequences, the benefits and risks of treatment must be balanced. In intensified diabetes management, hypoglycemia is not an insurmountable problem but is unfortunately inevitable using the methods of glucose control currently available. Patients with type 1 diabetes seem to be at greater risk than patients with type 2 disease. The health care team must strive to help the patient maintain normoglycemia. The results of the DCCT and the United Kingdom Prospective Diabetes Study prove that near normoglycemia is clearly in the patient's best interest. Patient education has become focused on minimizing hyperglycemia; counseling on the dangers of hypoglycemia has not been given the same stature. Emphasis must be placed on minimizing even minor subclinical hypoglycemia because it will contribute to a vicious cycle of hypoglycemia begetting hypoglycemia.
