A Saudi man has reportedly lost more than 700 pounds (320kg), six months after the King Abdullah ordered him hospitalised.
In August, Khalid bin Mohsen Shaari weighed 1,345 pounds (610kg) and the Saudi monarch intervened for him to undergo treatment in Riyadh.
Shaari was unable to move by himself and was transferred from Jazan in southern Saudi Arabia.
Dr Aa'ed al-Qahtani, head of the medical team overseeing Shaari's treatment, was quoted as saying that the patient's health was improving at a steady rate.
In comments published by Sayidaty magazine, he said Shaari has improved heart and lung function, reduced inflammation and improved muscle strength, including the ability to move his feet.
A custom-made wheelchair has reportedly been built to help Shaari become more mobile and aid his physical therapy.
Before being taken out of his house on a forklift, Shaari had not left his bed for three years.
According to the Guinness World Records, the heaviest person in medical history was American Jon Brower Minnoch who weighed 635 kg.
According to a recent United Nations study, Kuwait led the way in highest proportion of obese adults in the GCC, with 42.8 percent falling into this bracket in 2008, followed by Saudi Arabia at 35.2 percent.
Another report by Frost & Sullivan claimed that GCC healthcare expenditure will triple to $133.19bn by 2018, partly on the back of rising incidences of lifestyle diseases, which appallingly have an incidence rate in the region of about 20 percent.For all the latest health tips & news from the UAE and Gulf countries, follow us on Twitter and Linkedin, like us on Facebook and subscribe to our YouTube page, which is updated daily.
