What is PNH?
You are more than your PNH
What is PNH? Paroxysmal nocturnal haemoglobinuria, or PNH, is a blood disease that is caused when the cells responsible for making red blood cells (which help to carry oxygen around the body) mutate and produce defective blood cells.1 This triggers the immune system - a sophisticated defence network that keeps the body safe from dangers like disease and infection - to attack and destroy these defective red blood cells, a process called haemolysis.2
PNH is a rare disease that can affect anyone of any age, race or gender. No one is born with PNH; it is known as an 'acquired disease', which means it cannot be inherited and it is not contagious.3
