Indian doctors said Thursday that an Egyptian who is believed to be the world's heaviest woman had successfully undergone weight-loss surgery after losing over 100 kilograms.

Eman Ahmed Abd El Aty, who previously weighed around 500 kilos, had not left her house in Egypt in over two decades until arriving in Mumbai last month for bariatric surgery.

"We are happy to inform all well-wishers that the medical team of Saifee Hospital has successfully performed the surgery on Eman Ahmed," said a statement.

"Eman successfully underwent a Laparoscopic Sleeve Gastrectomy on March 7th 2017 at Saifee Hospital. She had an uneventful surgery and anaesthesia course.

"She is now on oral fluids and accepting them well. The future course of action for the medical team working on her will be to correct all her associated medical problems, to get her fit enough to fly back to Egypt as soon as possible," it added.
