Disorder relating to blood

Main disorder	Specific	Brief details
Anaemia	Irondeficiency Anaemia	Results from deficiency of iron usually due to blood loss or poor nutrition.
	Vitamindeficiency Anaemia	Results from low levels of Vitamin B12 or folic acid due to poor nutrition.
	Aplastic Anaemia	Occurs when the body stops making enough red blood cells. This may be due to viral infections, exposure to toxic chemicals, drugs, and autoimmune diseases.
	Hemolytic Anaemia	Occurs when abnormal breakdown of red blood cells takes place.
	Sickle Cell Anaemia	It is a hereditary blood disorder, in which red blood cells taking a rigid, sickle shape. This decreases the cells' flexibility and may result in lifethreatening complications.
Bleeding Disorders	von Willebrand Disease	It is the most common hereditary coagulation abnormality that results when the blood lacks von Willebrand factor, a protein that helps the blood to clot.
	Haemophilia	It is a rare, usually inherited, bleeding disorder characterised by body's inability to control blood clotting or coagulation. It results from a genetic defect in Xchromosome.
Blood Cancers	Leukemia	Characterised by rapid production of abnormal white blood cells which cannot fight infection and also impair the ability of the bone marrow to produce red blood cells and platelets.
	Lymphoma	Lymphoma is a type of blood cancer that occurs when lymphocytes, the white blood cells that form a part of the immune system, divide faster than normal cells or live longer than they are supposed to.
	Myeloma	This type of cancer targets the plasma cells which produce antibodies, thus weaken the immune system of the body.
