Your Blood Is Weak...!
Risk factors of Anaemia
Anaemia is one of the most significant public health problems especially among children in the world. Therefore, an indebt knowledge and/ or understanding of the risk factors and Complications of anaemia will give us more insight to its nature and ways that can better be adopted to fight it.

Anaemia is a medical condition that is said to occur when there is a significant decrease in the amount of red blood cells (RBCs) and therefore unable to transport sufficient amount of oxygen to organs and tissues in the body. As a result, anaemic patients experiences varying levels of exhaustion even if they have rested very well.

Risk Factors of Anaemia

Anybody can develop anaemia for several reasons. Children, pregnant women, people who don't have access to healthy diet, cancer patients, sickle cell anaemia patients, etc.

However, women of childbearing ages are at higher risk of developing anaemia because of the conditions of loss of blood during menstruation.

Pregnant women are also highly prone to anaemia as a result of reduced levels of iron and folate (folic acid) in the blood, since during the first and second trimester of pregnancy, the fluid portion of a woman's blood or blood plasma increases in volume or expands faster than the total number of red blood cells (RBCs), i.e the total blood volume. This eventually dilutes the blood and therefore, may lead to anaemia.


Is also a number one risk factor for anaemia. This could come as a result of internal bleeding which could arise as a result of some alcohol related disease such as ulcer, and as well as folic acid and vitamin B deficiencies which is common to alcoholics.

Poor Iron Diet

This is also a major risk factor. People whose diets are poor in iron, for example, vegetarians and People who eat lots of processed foods have a tendency of developing iron and folate deficiency which is a major cause of iron deficiency anaemia.

Sickle Cell Anaemia

This is a genetic condition and can be inherited by those who come from a family line where it exists. It is most problematic when a person inherits the two Sickle cell genes (SS). A single Sickle cell gene (AS) can be of an advantage as those having it are resistant to malaria.

Other major risk factors of anaemia may include:

  • Long term Infections,

  • Long term illness such as kidney disease, liver disease,

  • Cancer, diabetes, HIV /AIDS, inflammatory bowel disease could also be a factor,

  • Diets low in iron, vitamin or minerals,

  • A family history of inherited anaemia such as Sickle cell anaemia or thalassemia,

  • Diseases such as rheumatoid arthritis, heart failure, thyroid disease, etc.
