Egyptian woman Eman Ahmad undergoes bariatric surgery in Mumbai

Eman Ahmed Abd El Aty before and after her treatment

Eman Ahmed, 36, had weighed 78 stone but doctors reduced her stomach by 75 per cent in the operation at Saifee Hospital in Mumbai in India two days ago.

Eman Ahmed Abd El Aty, 37, initially weighed some 500 kilograms because of her elephantiasis, a pathology that causes swelling of the limbs and other parts of the body.

Eman has been in hospital since early February when she was moved out of her home for the first time in 25 years by removing the wall from her room, and a crane to lift her out of her bed.

Eman Ahmed, who arrived in India at the Saifee Hospital in Mumbai last month for treatment has undergone her first surgery after losing over 100 kilograms.

Eman Ahmed, after her first laparoscopic sleeve gastrectomy surgery, is able to sit.

"We are trying to get her fit enough to fly back to Egypt as soon as possible", the hospital said in a statement, according to the BBC.

According to India Today, doctors treating Abd El Aty plan on making her lose 440 pounds in half a year.

There is no history of obesity in her family, inclining the doctors to suspect a genetic mutation may be responsible for the uncontrolled weight gain.

Eman's condition will now be monitored before the next surgery is fixed to bring her down to a lean and trim 100 kgs or so.

Last month, world's heaviest women in the world from Egypt arrived at the India's biggest city Mumbai for her bariatric surgery.

Diagnosed with a parasitic disease called Elephantiasis - a condition that causes the limbs and other body parts to swell, leaving her nearly immobile - Eman also suffers from sleep apnea, hypothyroidism, diabetes, hypertension, kidney problems and fluid retention.

Bariatric surgery, also known as weight loss surgery, is used as a last resort to treat people who are dangerously obese and carrying an excessive amount of body fat.

She suffered a cerebral stroke as a child which left her bed-ridden and she piled on the pounds.
