35-year-old Mr Shirhan S/O Omar Khtab had not been able to sleep well for many years. Tipping the scale at 150kg, Shirhan would get breathless if he slept on his back and would wake up frequently. He had to lie with his face down, propping his forehead with his hand. This left a dark patch on his forehead which bothered him. He also suffered from painful knees and ankles which ached when he walked for more than 10 minutes.
