Bigorexia is often referred to as the opposite of anorexia.
Those living with it believe they are not muscular enough, and many go to extreme lengths to bulk up further. But in their pursuit of the "perfect body" some have gone too far, with devastating results.
Known officially as muscle dysmorphia, the condition is thought to affect thousands of people, mainly men, across the UK.
BBC Newsbeat joins BBC Asian Network on a journey to meet some of the people who just can't stop pumping iron, the gym owner who says it's rife, the grieving mother who believes she lost her son to Bigorexia and the medical expert who warns that this condition is being ignored.
