How is hyperglycemia defined?

Hyperglycemia is defined as a high concentration of glucose in the blood. This condition typically occurs when insulin is insufficient or when the body is unable to effectively utilize insulin, resulting in elevated blood sugar levels. It is commonly associated with diabetes mellitus, where the body either does not produce enough insulin (type 1 diabetes) or cannot use insulin effectively (type 2 diabetes).

Understanding hyperglycemia is crucial because it can lead to various complications if not properly managed, including dehydration, ketoacidosis, and long-term cardiovascular issues. Recognizing the symptoms of hyperglycemia, such as increased thirst, frequent urination, and fatigue, is essential for effective patient care.
