Manuel Uribe, who at 550 kg, is possibly the heaviest person in the world. No one has managed to find suitable scales for Uribe in years and estimates of his weight are made partly by tape-measure. Uribe's case puzzles doctors since his cholesterol and blood-sugar levels are normal, despite his extreme obesity.
Uribe, bedridden for the past five years, cannot stand on his own and will need a special flight to take him from Mexico to Italy, where a surgical team has offered to perform an intestinal bypass free of charge to help him shed weight.
