Hypoglycemia in diabetes: The dark side of diabetes treatment. A patient‐centered review

Hypoglycemia is a frequent occurrence in patients with diabetes who are treated with insulin and insulin secretagogues. Hypoglycemia is the limiting factor that prevents patients from achieving the glycemic control known to reduce the microvascular complications of diabetes. Recurrent episodes of hypoglycemia can lead to impaired awareness of hypoglycemia where the first symptom of a low blood sugar is unconsciousness. The fear of hypoglycemia has a significant effect on the quality of life of patients and their families. In the acute setting, hypoglycemia can kill, and clinical trials have demonstrated that a single episode of severe hypoglycemia increases the risk of subsequent mortality and cardiovascular events. Clinicians must make efforts to recognize and prevent hypoglycemia in order to prevent the adverse events associated with this event. Patient education is central to these efforts. Recent developments in glucose monitoring and drug development have provided more approaches that can be used to reduce the risk of hypoglycemia in patients with diabetes.     

Changing environment of hyperglycemia in pregnancy: Gestational diabetes and diabetes mellitus in pregnancy

The diagnosis and treatment of gestational diabetes mellitus (GDM) have been in a state of flux since the World Health Organization accepted and endorsed the International Diabetes and Pregnancy Study Group's diagnostic pathway and criteria in 2013. These new diagnostic criteria identify an increasing number of women at risk of hyperglycemia in pregnancy (HGiP). Maternal hyperglycemia represents a significant risk to the mother and fetus, in both the short and long term. Controversially, metformin use for the treatment of GDM is increasing in Australia. This article identifies the multiple and varied presentations of HGiP, of which GDM is the most commonly encountered. The degree of maternal hyperglycemia experienced affects the outcomes for both the mother and neonate, and specific diagnosis determines the appropriate treatment for the pregnancy. Given the increasing incidence of women with dysglycemia and those developing HGiP, this is an important area for research and clinical attention for all health professionals.
