The aim of red blood cells in the body is to transport oxygen from the lungs to other regions of the body via a protein called haemoglobin.
Anemia is a condition in which the cells do not acquire sufficient oxygen from the blood. It is mostly caused by a lack of red blood cells (RBCs) or haemoglobin in the blood. Anemia can be caused by a number of disorders, including blood loss due to persistent bleeding, iron deficiency, renal illness, stomach ulcers, pregnancy, poor nutrition, unusually low RBC production, and excessive RBC destruction.
Depending on the cause and degree of anaemia, several signs and symptoms may be present. Your anaemia may not create any symptoms at all, depending on the underlying reasons.
If signs and symptoms are present, they may include:
- skin that becomes yellow or pale
- abnormal heartbeats
- breathing difficulty
- Unsteadiness or faintness
- chest pain
- chilly fingers and toes
Anemia may initially be so mild that you are unaware of it. However, when anaemia progresses, symptoms get worse.
