Physicians have also said that due to a "disruption of glands", her body stores and retains more water than it should.

As a baby, Iman learnt to get around using her hands. But by the age of 11 she couldn't support herself while standing up due to her weight and thus resorted to crawling around the house.

She had to drop out of primary school after suffering a cerebral stroke, which left her bedridden.

Since then, Iman has remained in her room — totally stationary and unable to do anything.
