THE fattest person in Spain is due to undergo a stomach bypass in Barcelona this week to help him lose just over 25 stone.
Gustavo Moreno, 31, originally from Colombia, weighs just under 41 stone (260 kilos), but has reached 44 stone (280 kilos) in the past.
He has to lose 160 kilos within a year and a half if he is ever to lead a normal life, say medics.
Doctors warn that his health is in serious danger and his excess weight is likely to kill him soon if action is not taken.
Although always plump as a child, Gustavo reveals that his weight did not start to become a serious problem until he was 15.
“Right now, I can't work or do any activity, and I want to lose weight to be able to go back to working in the airport that I had a job at before, and because I've got a girlfriend and I want to lead a normal life,” Gustavo reveals.
Other members of his family are said to have similar problems, with his 19-year-old sister due for a stomach bypass on Thursday at Barcelona's Clínica Teknon.
The team at the clinic, led by Doctor Carlos Ballesta, say Gustavo has 'all the health problems associated with obesity, such as high blood pressure, diabetes, ventricular hypertrophy, auricular dilation and an insufficient heartbeat.
It means he is at serious risk of suffering from a heart attack.
Doctor Ballesta has already operated on around 3,000 obese patients – the record being a man from Paraguay who weighed 317 kilos (just under 50 stone) and now weighs 90 kilos (about 14 stones and two pounds).
He says the average bodyweight of clinically-obese patients needing operations has risen from between 20 and 24 stone (130 to 150 kilos) to between 28 and 30 stone (180 to 190 kilos).
The average age of a patient is 39, and 69 per cent of his patients are female.
