Study Notes
Anaemia Definition
- Anaemia is a condition with insufficient red blood cells or oxygen-carrying capacity to meet physiological needs.
- Physiological needs vary by age, sex, altitude, pregnancy status and smoking.
- The WHO criteria for anaemia is Haemoglobin < 12g/dL in non-pregnant women & Haemoglobin < 13g/dL in men.
Blood Production
- Blood is made in the bone marrow.
Anaemia Types
- This lecture outlines types of anaemia other than haemolytic anaemia.
- Categories:
- Iron deficiency anaemia
- Vitamin B12 deficiency anaemia
- Folate deficiency anaemia
- Aplastic anaemia
Anaemia Pathophysiology
- Anaemia is a reduction in Haemoglobin due to a disorder of globin or heme.
Introduction
- Anaemia is a condition resulting from a reduction in hemoglobin (Hb) levels.
- Hb levels are reduced due to a disorder of either globin or heme.
- Haemoglobin levels are lower in women than in men: 12 g/dL in women and 13 g/dL in men.
Bone Marrow
- Blood is produced in the bone marrow.
Anaemia
- Anaemia occurs when there are insufficient red blood cells or insufficient oxygen-carrying capacity to meet the body's metabolic needs.
- Physiological needs vary based on age, sex, altitude, smoking, and pregnancy status.
- The World Health Organisation (WHO) criteria for anaemia considers Hb levels below 12 g/dL in women and below 13 g/dL in men as anaemic.
Definition of Anaemia
- Anaemia is a condition where the number of red blood cells or their oxygen-carrying capacity is insufficient to meet physiological needs.
- Physiological needs vary by age, sex, altitude, smoking, and pregnancy status.
- The WHO criteria for anaemia is Haemoglobin levels < 12g/dL in non-pregnant women and < 13g/dL in men.
Blood is Made in the Bone Marrow
- The bone marrow is the site of blood cell generation.
Generation of Blood Cells
- The bone marrow is responsible for the generation of all blood cells.
Anaemia
- Anaemia is a condition that can result from various causes, including iron deficiency, vitamin B12 deficiency, folate deficiency, and aplastic anaemia.
Anaemia Definition
- Anaemia is a condition where red blood cells or their oxygen-carrying capacity is insufficient to meet the body's needs.
- This can be due to a disorder involving the globin or heme components of haemoglobin.
Haemoglobin Levels
- Anaemia is defined as a haemoglobin level below 12g/dL in non-pregnant women.
- A haemoglobin level below 13g/dL in men is considered anaemia.
Blood Production
- Blood is produced in the bone marrow.
Anaemia Causes
- Anaemia can arise from various conditions, including:
- Iron deficiency
- Vitamin B12 deficiency
- Folate deficiency
- Aplastic anaemia
- The lecture focuses on types of anaemia other than haemolytic anaemia.
