Anaemia or Anemia: Symptoms, Causes and Complications

Definition of Anemia:

Anemia is a clinical condition characterized by pale coloration of the skin and mucous membrane due to qualitative and quantitative deficiency of hemoglobin below the lower limit in the peripheral blood in respect of age and sex.

Anemia is decreased in the total amount of red blood cells (RBCs) or hemoglobin in the blood, or a lowered ability of the blood to carry oxygen.

Normal Hb Level:

  • Male- 13-18 gm /dl,
  • Female -11.5-1 6.5 gm / dl,
  • Children -16- 19 gm/ dl,
  • At birth- 18-20 gm/ dl.

2. Children 6ycars to 14ycars- 12 g/dl

3. Above 14 years
