Susan Wellings suffers from severe pain caused by gallstones. She was told that an operation would solve the problem but has been left waiting for the procedure after doctors would not allow her to have the surgery.
She says that the pain she experiences from the gallstones is making her life 'hell'.
Doctors initially told Susan that she could not have the operation because she was overweight.
She joined a gym to help her lose weight but was then diagnosed sleep apnea - a disorder than affects a person's breathing whilst they are asleep.
Susan has since been given a sleep apnea machine to help her with the condition and is coping with it well.
Doctors in the Abertawe Bro Morgannwg University Health Board then told Susan that her issues would give her a 50/50 chance of surviving the operation, if they were to go ahead with it.
However, she has been unhappy with the way her case has been handled by her local health board.
