Eman Ahmed Abdel-Ati, an Egyptian believed to have been the world's heaviest woman before undergoing surgery, is receiving treatment in Abu Dhabi with the goal of being able to move autonomously using a wheelchair within three months, an official of Burjeel Hospital said on Sunday.

Abdel-Ati was transferred to the hospital in Abu Dhabi on Thursday after receiving treatment in India. 

"She is expected to be transferred out of the intensive care unit on Sunday to continue her treatment plan," Yassin Al-Shahat, the executive medical manager of Burjeel Hospital, said at a press conference.

Al-Shahat explained that the medical team is working on treating Abdel-Ati for a number of maladies, including a bone defect, a defect in her heart valve, bed sores and infections.

"Her condition is being evaluated by a medical team of 20 doctors," he added, according to Emirati Newspaper Al-Ittihad.

Abdel-Ati, 36, weighed some 500 kilograms (1,100 pounds) before undergoing surgery in Mumbai in March, which doctors said resulted in her shedding around a fifth of her weight.

In February, Abdel-Ati made headlines all over the world when she was flown to Saifee Hospital in Mumbai to undergo weight loss surgery.

On 21 April, Saifee Hospital announced that Abdel-Ati lost 250kg two months after undergoing the surgery.

However, her sister Shaimaa Selim, who was accompanying her sister in India, accused the hospital and the doctor in charge of treating her sister of lying, asserting that Abdel-Ati lost only 50kg and had suffered a stroke, which the Indian hospital denied.

Shortly after, Selim asked the UAE for medical assistance, to which Abu Dhabi agreed.

On Friday, an Egyptian diplomatic delegation visited Abdel-Ati to check on her condition.

Before travelling to India, Abdel-Ati had not left her home in Egypt's Mediterranean port city of Alexandria for two decades, according to AFP.

Her family told doctors that she was diagnosed as a child with elephantiasis, which left her almost immobile.
