Anaemia is a widespread blood disorder that is characterized by a decrease in red blood cells or haemoglobin in the blood. Having sufficient haemoglobin in the blood is an essential requirement for our well-being as it ensures the fundamental delivery of oxygen to tissues and organs in the body. It has been estimated that about half of worldwide anaemia cases are caused by iron deficiency, or in other words by not having enough iron in the blood. Other nutritional deficiencies such as folate, vitamin B12, riboflavin and vitamin C deficiency have also been shown to play a role in anaemia development. Inflammation, infection, and thalassemia (an inherited disease that accounts for loss of red blood cells) have also been tied to anaemia.
