Doctors have been left scratching their heads after a morbidly obese man weighing over 42 stone has been left unable to move or talk.

Abdul Jabbar Tunio, 39, from Larkana in Pakistan, has been paralysed and kept silent by a mysterious condition for the past two months, reports the Express Tribune.

Such is the seriousness of his illness that he has also been unable to eat or drink.

His concerned family have taken him to various doctors, but none had the facilities or expertise to analyse his condition.

Fortunately Jinnah Postgraduate Medical Centre’s (JPMC) intensive care unit, in Karachi, offered him treatment - but even their expert medical team are unsure what the route of his problem is.

Despite his current struggle, the father-of-three has not always been in such an unhealthy state, only becoming overweight as an adult.

He broke his leg as an 18-year-old and his family believe that his obesity can be linked back to the medication he took while he was recovering.

Since then his weight has ballooned leaving him suffering from severe breathing problems, renal complications and skin ulcers.

Such is Jabber's size that the hospital does not even have a bed to accommodate him.

However, they have ordered a bespoke bed so that he can be treated at the facility in comfort.

Professor Rasheed Khan Durrani told the Express Tribune: 'Right now, he is not stable but we are hopeful that he will recover.

'We are trying hard to stabilise the patient. We are trying to ascertain the cause of the weight gain so that we can further proceed with his treatment.'

A medical board has now been assembled to find the cause of Abdul's condition, including a general physician, general surgeon, nephrologist and chest physician.
