Overview

Anemia is a medical condition characterized by a deficiency of healthy red blood cells or hemoglobin in the blood. Hemoglobin is responsible for carrying oxygen from the lungs to the body’s tissues. When red blood cell levels are low, the body does not receive adequate oxygen. This can affect energy production and organ function. Anemia can develop gradually or suddenly, depending on the cause. It affects individuals of all ages. The severity may range from mild to life-threatening. Persistent anemia may impact heart and brain function. Early detection is important to prevent complications. Proper evaluation helps determine the underlying type and severity.

In anemia, the oxygen-carrying capacity of the blood decreases. Tissues and organs receive less oxygen than required. The heart may pump faster to compensate for reduced oxygen delivery. This can lead to fatigue, weakness, and shortness of breath. Severe anemia may strain the cardiovascular system over time.

Diagnosis

Diagnosis is confirmed through blood tests, particularly a complete blood count (CBC). Hemoglobin and hematocrit levels are measured. Additional tests may evaluate iron levels, vitamin B12, folate, or bone marrow function depending on suspected cause.
