Can This Be the Fattest Baby in the World? ......He is Just 18 Month Old Baby! (See Photos)

Disturbing photos of a baby suffering from a strange deficiency that increases her body size excessively has emerged with doctors putting heads together to tackle the ailment.

Baby Aliya Saleem and her father

A morbidly obese toddler tips the scales at 53lbs (24kg) - making her one of the heaviest girls in the world for her age.

In March 2015, 18-month-old Aliya Saleem weighed 41lbs (18kg) and her incredible size garnered worldwide attention. A video about Aliya and her family’s ordeal received more than 21 million views on YouTube channel Barcroft TV.

But her mother Shabnam Parveen and father Mohammad Saleem, who live in Jharkhand, in the Indian district of Ranchi, were left baffled by what was causing their daughter's insatiable appetite.

Now a paediatrician at the nearby Orchid Medical Centre has formulated a number of theories about what could be behind Aliya's ever-expanding waistline.

Dr Bhavya Kumar has examined Aliya and believes she could be suffering from Prader-Willi syndrome - a rare disorder characterised by learning difficulties, growth abnormalities, and obsessive eating.

He said: "There could be some hormonal imbalance, there could some metabolic disease. There can be some genetic causes. It could be because of some tumour. But because there is a history of sibling loss with similar complaints, that points towards a genetic cause.

"So, I strongly suspect that this could be a case of some genetic disorder, most probably Prader-Willi syndrome, which is a very rare disorder.”
