DUBAI, Sept. 25 (Xinhua) -- Iman Abd Al-Ati, once the world's heaviest woman, at weight 500 kg, passed away early Monday in Abu Dhabi in the United Arab Emirates (UAE), local media reported.

The Egyptian woman succumbed to "complications from the underlying comorbid conditions," including heart disease and kidney dysfunction, said the report quoting medical experts at Burjeel Hospital in Abu Dhabi.

Abd Al-Ati underwent treatment in the UAE capital and had managed earlier in the year to lose 65 kg in the hospital, the UAE state news agency WAM reported.

She had been under the supervision of over 20 doctors from different specialities, said the report.

Abd Al-Ati, 36, arrived at the Bureej hospital in Abu Dhabi on May 4 to complete her treatment trip which was started in Mumbai, India.

She suffered from "a disruption of the glands and elephantiasis disease," causing huge amounts of water to be retained in the body, according to a report by Dubai-based news channel Al Arabiya.
