I. Introduction
Anemia is a medical condition characterized by a deficiency of healthy red blood cells, leading to inadequate oxygen supply to the body's tissues. It is often associated with low hemoglobin levels and can cause fatigue and weakness. Anemia can manifest in various forms, each with its own underlying cause, and its severity can range from mild to severe. It is important to seek medical attention if you suspect you have anemia, as it can be an indication of a more serious underlying illness.
