Anemia overview and common mechanismsAnemia refers to a clinical condition where the haemoglobin level reduces, which leads to inadequate delivery of oxygen to the tissues. It may be a result of reduced red blood cell production, increased destruction of RBCs, or even blood loss. Common symptoms include fatigue and pallor.

It can occur due to long-term loss of blood, poor dietary habits, malabsorption syndrome and even increased demand of the body. The person shows features like hair loss, pica and fatigue. Treatment usually involves oral iron therapy.

A peripheral blood smear may aid in identifying characteristic features like macrocytosis. Neuropathy may occur in such cases.

The affected persons show clinical features like pallor and weakness. Oral supplementation of folic acid and eating a healthy diet can help reduce the chances of anemia.

While the shape of the red blood cells remains normal (normocytic), serum iron levels may be low in some cases. The underlying disease must be treated to deal with this.

Reduced levels of thyroid hormones (hypothyroidism), can cause a reduction in red blood cell production, thus leading to this condition. Cold intolerance and weight gain are seen, along with anemia.

Such persistent loss of blood exceeds the body’s ability to replace iron, which can lead to iron deficiency anemia. The affected persons show clinical experiences breathlessness on exertion and pallor, along with a reduced tolerance for exercise.

Legumes and fortified cereals are rich in folate, and must be consumed regularly.

Prevention and treatment of infection like malaria and chronic inflammatory diseases may also reduce the chances of developing anemia.

Regular antenatal and paediatric checkups can help in monitoring growth and nutrition, and provide supplementation when necessary. A healthy lifestyle with regular exercise and adequate sleep, along with reduction of stress, improves overall nutrition and immunity.
