Egypt's Eman Ahmed, believed to be the world's heaviest woman, successfully underwent weight reduction surgery on Tuesday, doctors in India said.
"She is very happy, she started dancing in her bed," Dr. Muffazal Lakdawala said."Her smile has come back."
Before she traveled to India for her operation, Eman weighed 1,102 pounds (500 kg) and she'd barely left her bedroom in more than two decades, her family said.
Over the last couple of years she'd been confined to her bed after a stroke severely impaired her speech and mobility.
"She is battling with her life every single day," Lakdawala said last year. "Right now she is like a living bombshell, which could blow up on her any moment."
But Lakdawala said on Thursday that since Eman arrived at the Saifee Hospital in New Delhi in February she'd lost more than 220 lbs (100 kg).
"Her parameters are all stabilized, kidney is much better, electrolytes are much better," he said, adding that they had a "window of safety" to perform the surgery -- a laparoscopic sleeve gastrectomy.
"She has done well post-surgery; she's back in her room and taking liquids," he said.
He said if all went well, the intention was to take another 155 to 175 pounds (70 to 80 kg) off her weight before sending her home to Egypt within the next couple of months.
The next surgery will be next year, Lakdawala said.
