Eman Ahmed Abd El Aty, a 36-year-old Egyptian woman believed to be the world’s heaviest at 1,100lb, has undergone weight loss surgery at an Indian hospital.

A spokesperson at Mumbai’s Saifee Hospital said the patient had already lost 220lb since arriving in India in January.

The hospital said in a statement: “We are trying to get her fit enough to fly back to Egypt as soon as possible.”

Eman Ahmed Abd El Aty’s family said she had not left her house for 25 years until she came to Mumbai on a chartered plane.

The surgery was performed by a team of doctors led by bariatric surgeon, Dr. Muffazal Lakdawala.

Bariatric surgery, also known as weight loss surgery, is used as a last resort to treat people who are dangerously obese (having a BMI of 40 or above or 35 plus other obesity-related health conditions).

Eman Abd El Aty’s family says she weighed 11lb at birth and was diagnosed with elephantiasis, a condition in which body parts swell due to a parasitic infection.

By the time she was 11, her weight had risen sharply and she suffered a stroke which left her bedridden.

She is cared for by her mother and sister.
