A CBC can help determine red blood cell size, hematocrit (percentage of blood volume made up by red blood cells), and hemoglobin. Blood tests such as a complete blood count (CBC) and serum ferritin level are useful for the diagnosis of iron deficiency anemia.Can result from inadequate iron intake, decreased iron absorption, increased iron demand, or increased iron loss.Accounts for approximately 50-percent of the diagnosed cases of anemia.Iron deficiency anemia is the most common type of anemia.However, this article will focus on just 7 types Anaemia is observed when Hb level is below 7.0g/dl. In pregnancy, range is varied and depends on the trimester, but generally greater than 10.0 g/dL. The normal haemoglobin(Hb) ranges are as follows: 13.5 to 18.0 g/dL in men 12.0 to 15.0 g/dL in women 11.0 to 16.0 g/dL in children. Symptoms depend on factors such as: the etiology of anemia, the acuity of onset, and the presence of other comorbidities e.g. Problems with growth, for children and teens.Pain, including in your bones, chest, belly, and joints.Dizziness, light-headedness, or feeling like you are about to pass out.

In severe cases, symptoms generally include: In mild cases there would be no presentation of symptoms.

Deficient erythropoiesis: Erythropoiesis is the process of red blood cell formation in a living tissue.Physiologically, anaemia results from a disproportionate loss of red blood cell compared to production. In 2010, it was found that Sub-Saharan Africa, South Asia, the Caribbean, and Oceania had the highest anemia prevalence across all age groups and both sexes īiological Mechanism of Anaemia.Race is also an important determinant of anemia, with the prevalence increasing in the African American population from e.g.

New-onset anemia, especially in those over 55 years of age, needs investigating and should be considered cancer until proven otherwise (especially true in men of any age who present with anemia ).

Other at-risk groups include alcoholics, the homeless population, and those experiencing neglect or abuse.

The prevalence is more than 20% of individuals who are older than the age of 85: incidence of anemia 50%-60% in the nursing homes in the elderly, approximately 33% of patients have a nutritional deficiency as the cause of anemia e.g.

According to WHO, 42% of children less than 5 years of age and 40% of pregnant women globally are anaemic It is a global health concern affecting majorly pregnant women and young children. Oftentimes, it is mild and asymptomatic, requiring no management. Anaemia affects one-third of the world's population.
