Bablu was cruelly dubbed a 'devil's child' by his neighbours because he suffers from local gigantism. They didn't understand why his arm had developed in such a way.
As a result, 25 year old Bablu was forced to flee his hometown to start a new life for in Mumbai.
A local journalist recently followed Bablu around the streets of the city and filmed him as he went about his daily routine.
The video shows Bablu eating at a restaurant. He demonstrates the difficulty he has in doing something as simple as holding a cup of water.
'Bablu has been disowned by his family as his neighbours think he is 'a devil's child'. The stigma that comes with the rare condition has forced him to migrate to Mumbai.
'He thought he would disappear in the crowd of millions and start making a living, but he met the same fate in the city as people were scared of his hand.'
The journalist explained Bablu has also found it extremely difficult to get a job of any kind since moving to Mumbai.
'If he is treated properly, his bulky hand that weighs 20kg can be reduced to normal size,' the journalist continued.
'However, [doctors] underlined that it will never be like a normal hand as the condition has reached an advanced stage.'
Gigantism, also known as acromegaly, is the result of an over-productive growth hormone.
Local gigantism causes a certain part of the body to grow excessively - most commonly fingers and toes - but as is the case with Bablu, it can also result in an entire limb being enlarged.
