What does the term "anemia" refer to?

The term "anemia" specifically refers to a deficiency of red blood cells or hemoglobin in the blood. This condition can lead to a reduced capacity of the blood to carry oxygen, which is essential for the body's tissues and organs to function properly.

Anemia can manifest in various forms and can be caused by a range of factors, including nutritional deficiencies (such as iron, vitamin B12, or folate), chronic diseases, genetic disorders, or bone marrow problems. The main consequence of anemia is fatigue and weakness, as the body is not receiving enough oxygen.

Understanding this term is crucial in medical practice, as anemia can be a sign of underlying health issues that may require further investigation or treatment. It distinguishes itself clearly from conditions related to white blood cells, blood sugar levels, or liver function.
