ABSTRACT
La hipoglucemia inadvertida (HI) es una complicación del tratamiento de la diabetes mellitus tipo 1 (DM1) y DM2 tratada con insulina o sulfonilureas, que se caracteriza por una capacidad reducida para percibir el inicio de los episodios de hipoglucemia. En general, coexiste con una insuficiente respuesta hormonal contrarreguladora a la hipoglucemia denominada falla autonómica asociada a la hipoglucemia (FAAH). El desarrollo de HI y de falla contrarreguladora a la hipoglucemia aumentan significativamente el riesgo de hipoglucemias severas. Se han desarrollado escalas de puntuación para identificar, en la consulta clínica, a este grupo de personas con elevado riesgo de hipoglucemias severas. La piedra angular del tratamiento consiste en evitar las hipoglucemias mediante una intervención multifactorial de cuidados clínicos y educación estructurada.
Hypoglycemia unawereness is a complication of type 1 diabetes treatment and of type 2 diabetes treatment treated with insulin or sulfonylureas, characterized by a reduced ability to perceive the onset of episodes of hypoglycemia. In general, it coexists with an insufficient counterregulatory hormonal response to hypoglycemia called: hypoglycemia associated autonomic failure (HAAF). The development of hypoglycemia unawereness and counterregulatory failure to hypoglycemia significantly increase the risk of severe hypoglycemia. Scoring scales have been developed to identify this group of people at high risk of severe hypoglycemia in the clinic. The cornerstone of treatment is to avoid hypoglycemia through a multifactorial intervention of clinical care and structured education.

Hypoglycemia is a major barrier to achieving the glycemic goal in patients with type 2 diabetes. In particular, severe hypoglycemia, which is defined as an event that requires the assistance of another person to actively administer carbohydrates, glucagon, or take other corrective actions, is a serious clinical concern in patients with diabetes. If severe hypoglycemia is not managed promptly, it can be life threatening. Hypoglycemia-associated autonomic failure (HAAF) is the main pathogenic mechanism behind severe hypoglycemia. Defective glucose counter-regulation (altered insulin secretion, glucagon secretion, and an attenuated increase in epinephrine during hypoglycemia) and a lack of awareness regarding hypoglycemia (attenuated sympathoadrenal activity) are common components of HAAF in patients with diabetes. There is considerable evidence that hypoglycemia is an independent risk factor for cardiovascular disease. In addition, hypoglycemia has a significant influence on the quality of life of patients with diabetes. To prevent hypoglycemic events, the setting of glycemic goals should be individualized, particularly in elderly individuals or patients with complicated or advanced type 2 diabetes. Patients at high-risk for the future development of severe hypoglycemia should be selected carefully, and intensive education with reinforcement should be implemented.
