Stress hyperglycemia
Stress Hyperglycemia
Stress hyperglycemia (pronunciation: /ˈstraɪs/ /ˌhaɪ.pər.ɡlaɪ.siː.miː.ə/) is a medical condition characterized by elevated blood glucose levels in the context of acute illness or stress.
Etymology
The term "stress hyperglycemia" is derived from the Greek words "hyper" meaning over or above, "glykys" meaning sweet, and "haima" meaning blood. The prefix "stress" is added to denote the condition's association with physical or emotional stress.
Definition
Stress hyperglycemia is a transient increase in blood glucose levels in response to stressful situations or acute illness. It is commonly observed in patients who are critically ill or undergoing surgery. The condition is different from diabetes mellitus, although the two can coexist.
Causes
Stress hyperglycemia is caused by a complex interplay of hormones such as cortisol, glucagon, and epinephrine, which are released during periods of stress. These hormones increase glucose production and decrease glucose utilization, leading to elevated blood glucose levels.
Symptoms
Symptoms of stress hyperglycemia may include frequent urination, increased thirst, and fatigue. However, these symptoms are often overshadowed by the symptoms of the underlying illness or stressor.
Treatment
Treatment of stress hyperglycemia involves managing the underlying cause of stress and maintaining blood glucose levels within a target range. This may involve the use of insulin therapy or other glucose-lowering medications.
