Hypoglycemia is an important and harmful complication of Diabetes Mellitus (DM) that often occurs in inpatient or outpatient settings. Hypoglycemia can be divided into two types, i.e. primary hypoglycemia when hypoglycemia is the main diagnosis for admission, whereas secondary hypoglycemia if hypoglycemia occurs during hospitalization. Hypoglycemia during hospitalization or secondary hypoglycemia may arise from various risk factors, such as advanced age, comorbid diseases, type of diabetes, previous history of hypoglycemia, body mass index, hyperglycemia therapy given, as well as other risk factors such as inadequate glucose monitoring, unclear or unreadable physician instructions, limited health personnel, limited facilities, prolonged fasting and incompatibility of nutritional intake and therapy administered. Hypoglycemia can lead to medical and non-medical impacts, such as increased mortality, cardiovascular disorders, cerebrovascular disorders, and increased health care costs and length of stay. The incidence of inpatient hypoglycemia can actually be prevented by controlling modifiable risk factors and also giving education about hypoglycemia to patients and health workers. We performed a literature research in Pubmed, EBSCOhost, and Scopus to review the possible risk factors for inpatient hypoglycemia. Eleven studies were retrieved. We presented the result of these studies as well as a brief overview of the epidemiology, pathophysiology, impact and preventive strategy.
