Anemia is a medical condition characterized by a deficiency in the number of red blood cells or the amount of hemoglobin within these cells. Hemoglobin is the protein responsible for transporting oxygen from the lungs to tissues throughout the body. When its levels are low, oxygen delivery is impaired, leading to various symptoms and health issues.

There are several types of anemia, each with different causes. Iron-deficiency anemia is the most common, resulting from inadequate iron intake, poor absorption, or chronic blood loss. Other types include vitamin-deficiency anemia, caused by deficiencies in vitamin B12 or folate; anemia of chronic disease, associated with long-term medical conditions like inflammation or infection; and hemolytic anemia, where red blood cells are destroyed prematurely.

Symptoms of anemia often include fatigue, weakness, pale skin, shortness of breath, dizziness, and cold hands or feet. The severity of symptoms can vary depending on the extent of the deficiency and the underlying cause.

Diagnosis typically involves a blood test called a complete blood count (CBC), which measures levels of hemoglobin, hematocrit, and red blood cells. Additional tests may be necessary to identify specific causes, such as iron levels, vitamin B12, or blood smears.

Treatment depends on the type and cause of anemia. Common approaches include dietary modifications, iron or vitamin supplements, medications to stimulate red blood cell production, or therapies to address underlying diseases. In some cases, blood transfusions or bone marrow pathology evaluations may be warranted.

Managing anemia effectively requires understanding its root cause, and early diagnosis can improve outcomes and prevent complications such as organ damage or severe fatigue.
