Eman who was admitted to the Mumbai hospital had weighed more than 500 kg.
Reports say the Egyptian woman was discharged from the hospital at around 12: 40 pm on Thursday for her further treatment in Abu Dhabi.
Egyptian woman Eman Ahmed, who was once the heaviest woman in the world and underwent a weight-loss surgery at Mumbai hospital, was discharged from Mumbai's Saifee Hospital on Thursday. Her treatment will be continued in VPS Healthcare, Abu Dhabi, UAE.
The initial weight loss needed in order to allow doctors perform bariatric surgery on her.
According to bariatric surgeon Muffazal Lakdawala, Emans weight has now come down to 170 kg from a whopping 498 kg on her arrival in India in February this year.
She had alleged that the doctors at Saifee, made "false claims" about Eman's complete recovery and weight loss of 262 kg. "We are happy that we did bring her weight down", Lakdawala said.

The bombing aimed to erode IS's capabilities in Afghanistan, but it was also seen as a warning to the much bigger Taliban group. The attackers all carried valid passes to the base, security sources told AFP, and were dressed in Afghan army uniforms.
"We have arranged for a hydraulic stretcher from Italy for Eman's journey and she will have doctors, paramedics and nurses with her during the journey", Sanet Meyer, director of medevac at VPS Burjeel, told AFP. The city traffic police arranged for a "green corridor" that enabled the ambulance bearing Ms. Ahmed to make the trip from Charni Road to the worldwide airport's Gate No. 5 in just 18 minutes, a journey that normally takes an hour.
Her sister, who had recently locked horns with Ahmed's doctor, expressed gratitude to the hospital staff and doctors by saying "Thank You". "So many years of disuse have compounded the problem".
She took to her Twitter handle and had said that Eman is ideal and fit.
The doctor said Shaimaa insisted she had wanted the hospital (Saifee) to keep Eman till she could walk.
"We are very thankful to the people of India to the doctors who treated Eman".
EgyptAir cargo airbus 300, fitted with medical equipment for shifting Eman to Abu Dhabi, took off at 7.41 pm from the Chhatrapati Shivaji Maharaj International Airport, an airport official said. "She will need multiple surgeries to straighten her hips and knees".
