Such foods include beef liver, asparagus, and red beans.

Pernicious anemia- Pernicious anemia usually affects people between the ages of 50 and 60 and is a result of a lack of vitamin B12. The disease can be hereditary but some forms of the condition can be autoimmune diseases. People who have any autoimmune diseasesare more likely to contract pernicious anemia. It is also macrocytic anemia 10. Aplastic anemia- Aplastic anemia is caused by an absence or reduction of red blood cells. This can happen through injury where the blood forming tissue in the bone marrow is destroyed. Because of this, the sufferer is unable to fight infection and is likely to be a heavy bleeder.

Complications include leg ulcers, shock, cerebral haemorrhage, and orthopaedic disorders.

Grading of anemia WHO Grading of Anemia: according to level of haemoglobin in blood 11: Grade 1 (Mild Anemia): < 10 g/dl Grade 2 (Moderate Anemia): 7-10 g/dl Grade 3 (Severe Anemia): < 7 g/dl Anemia is mainly diagnosed by haemoglobin level in blood. Haemoglobin concentration measurement is among the most commonly performed blood test, usually as part of a Complete Blood Count. Results are reported in g/L, g/dL or mol/L. Normal levels are: Women: 12.1 to 15.1 g/dL (121 to 151 g/L, or 7.51 to 9.37 mmol/L) Pregnant women: 11 to 12 g/dL (110 to 120 g/L, or 6.83 to 7.45 mmol/L)
