However, after her sister accused the Saifee hospital of improper treatment, she was flown for further treatment to Abu Dhabi. Although Eman lost about 330 kilos with her treatment in Mumbai, transferring her to Abu Dhabi seemed fatal. Eman passed away at 4.35 am on 25th September as a result of heart disease and kidney dysfunction.
