What condition is characterized by increased levels of blood sugar?

Hyperglycemia is the condition characterized by increased levels of blood sugar. It occurs when the body's ability to produce or respond to insulin is impaired, leading to an excess of glucose in the bloodstream. This can happen in various contexts, especially in diabetes mellitus, where it signifies the inability to regulate blood sugar effectively.

When hyperglycemia occurs, one may also experience symptoms like increased thirst, frequent urination, and fatigue. Prolonged hyperglycemia can lead to serious complications, including damage to blood vessels, nerves, and various organs over time. Understanding this condition is critical, especially in the context of managing diabetes and preventing its associated complications.

In contrast, hypoglycemia refers to low blood sugar levels, which is entirely opposite to hyperglycemia. Acidosis involves an excess of acids in the body fluids, not specifically related to blood sugar levels. Polydipsia is excessive thirst often caused by hyperglycemia but is a symptom rather than a condition related directly to increased blood sugar levels. Thus, hyperglycemia directly answers the question regarding elevated blood glucose levels.
