Overview of Anemia

Anemia is a medical disorder distinguished by a lack of RBCs (red blood cells) or hemoglobin in the bloodstream, causing a decline in the ability to transport oxygen to tissues and organs. Hemoglobin, a protein within red blood cells, attaches to oxygen in the lungs and carries it to various parts of the body.

Anemia can result from various underlying causes, including insufficient production of red blood cells, increased destruction of red blood cells, or excessive loss of blood. Common causes of anemia include vitamin insufficiencies, iron deficiencies, chronic diseases, inherited disorders like sickle cell disease or thalassemia, and other medical conditions affecting the bone marrow, kidneys or gastrointestinal tract.

Anemia is a prevalent health issue worldwide, affecting individuals of all ages and demographic groups. The probability of developing anemia may vary significantly depending on factors such as age, gender, geographic location, and socioeconomic status. Iron deficiency anemia is the predominant form of anemia worldwide, especially prevalent among children, teenagers, and women of childbearing age. Anemia of chronic disease is also prevalent, especially among older adults and individuals with chronic medical conditions including IBD (Inflammatory bowel disease), certain types of cancers or CKD (chronic kidney disease).
