Thirty-one-year-old Tanya Angus from Nevada in the USA, who was once a pretty and popular young woman, now stands at 6ft 8ins and weighs almost 32 stone. Tanya is already one of the tallest and heaviest women on the planet. Alarmingly, she is still growing, and lives in agonising pain. Now doctors say she is the only woman in the world whose growth cannot be halted by medication. This Bodyshock special follows Tanya's extraordinary journey as she struggles to come to terms with her unstoppable growth and joins the world's leading doctors in a race against time to ultimately save her life. Acromegalic Gigantism is an extremely rare condition that causes the body to grow to massive proportions, a condition that can transform anyone into a real-life giant. With unprecedented access to other Acromegaly sufferers, Bodyshock uncovers the enormous toll this unpredictable affliction takes on the human body and shows the groundbreaking technology top neurosurgeons are utilising in the battle to stop the growth. The programme follows the astonishing lives of three people as they cope with this colossal growth, and medical experts explain the science behind this little-known yet life-threatening disease.
