Nisa Karia, 30, has needed blood transfusions for most of her life, and she's received more than 1,300 units of blood so far.
Nisa was diagnosed with thalassaemia major when she was just five. This rare blood disorder means that she can't produce normal haemoglobin for her red blood cells, so she relies on donated blood to survive.
Growing up needing transfusions was hard, but it was just part of life. I always tell myself there are plenty of people out there who are worse off, she says.
Although Nisa needs blood transfusions every three weeks, her blood disorder hasn't stopped her realising her dream of working in London's fashion industry, after graduating from Leeds University.
Thanks to the wonderful people who give blood, I lead a full and active life. I'm also looking forward to getting married next year.
A blood transfusion is a process that involves taking blood from one person (the donor) and giving it to someone else (the recipient). Blood donors are unpaid volunteers. They're carefully selected and tested to make sure the blood they donate is as safe as possible.
There are several different types of blood transfusion. Whether or not you need one depends on a number of factors. If you're told that you might need a blood transfusion, you should ask why it's necessary and whether there are alternative treatments.
If you're going to receive a blood transfusion as part of a planned course of treatment, the doctor, nurse or midwife planning your transfusion will usually obtain your informed consent for the procedure. A sample of your blood will be taken before the transfusion to check that the blood you receive is compatible with your own blood.
Blood transfusions are a fairly common procedure. The risk of serious side effects is low, as your blood is tested against the donor blood to make sure it is compatible and you will be monitored regularly during the transfusion.
Motorsport fanatic, Mike Austin, 34, will never forget the summer of 2006. While on his way to work on his much-loved motorbike, he received a blood transfusion after his motorbike collided with a car.
