Anemia, characterized by a deficiency of healthy red blood cells or hemoglobin, can lead to fatigue, weakness, and shortness of breath due to insufficient oxygen delivery to tissues. Its various forms stem from diverse causes, spanning from short-term to chronic, mild to severe. Often serving as a harbinger of underlying health issues, anemia necessitates prompt attention and treatment, which may involve supplements, medical procedures, or dietary adjustments.

Symptoms of anemia vary depending on its severity and cause, with manifestations such as fatigue, weakness, pale skin, irregular heartbeat, and headaches. However, some cases may initially present no symptoms or have symptoms masked by underlying conditions. Therefore, it’s essential to seek medical attention if experiencing unexplained fatigue or breathlessness. Low hemoglobin levels, detected through blood tests or donor screenings, serve as a primary indicator of anemia and should prompt further medical evaluation to address potential underlying health concerns.
