Meet Terri Smith: The World's Fattest Woman

49 year old mother of one, Terri Smith, is believed to be the World's Fattest Woman, weighing 700lb. She is confined to her bedroom in her Ohio home unable to move, stand or roll over by herself.
Suffering from severe headaches which doctors fear could stem from a brain problem, Terri urgently needs a brain scan - but is too big to fit inside an MRI machine.
