Eman Ahmed who weighed over 500 kg, underwent 1.5 hour long surgery - a laparoscopic sleeve gastrectomy at Mumbai's Saifee Hospital, and has lost over 120 kg within a month after coming to Mumbai for the treatment. She was bedridden all her life, unable to move or even roll over in bed.
Asked about the effect of so much weight loss on her body and muscles, he said, "We are well aware of impact on the body of a patient when a lot of weight is reduced in a short period of time".
A spokeswoman for head doctor Muffazal Lakdawala said: "Eman has lost over 100kg and has been shedding weight gradually on a daily basis with all the treatment and support".
According to India Today, doctors treating Abd El Aty plan on making her lose 440 pounds in half a year.
Abd El Aty's doctors say she is now able to sit up and will be able to return to Egypt after several months of monitoring and physiotherapy.
Egyptian national Eman Ahmed had shot to instant fame when she was brought to Mumbai. For last two years she was restricted to her be.
Ahmed's BMI was 252 when she first arrived in India, which was ten times the normal limit.
Ms Abd El Aty, from Alexandria, has suffered a stroke and faced other serious conditions due to her weight including diabetes, high blood pressure, hypertension and sleep deprivation.
Ms Ahmed was accompanied by her sister, Shaimaa Ahmed, and a team of doctors from the hospital.
Lakdawala in Delhi responded and offered to help reduce Eman's weight.
The venture was fraught with difficulties from the start. Eman is getting about 1,750kcal every day, which is on a par with the average calorie intake of a woman - 1600-200Kcal.
Eman Ahmed Abd El Aty, 36, a resident of Alexandria in Egypt had not left her house in nearly 25 years until she arrived in the Indian financial hub, Mumbai in February, for a bariatric surgery.
But despite the hardships and roadblocks, for the Ahmed family, the opportunity for the 36-year-old to travel to India and have the surgery was a ray of light at the end of a very dark tunnel. Because Abd El Aty had no other option left, she tweeted about her problem, and this is how her story got exposure.
