Raj, 51, has been admitted to the Ram Manohar Lohia hospital where she was attended to by a team of doctors.
"She is conscious and her condition is stable. She is a diabetic and was having fever for the last two days. It seems that her blood sugar levels had dipped because she felt uneasy," said a senior doctor at the hospital.
"Her pulse and blood pressure has come out normal. Further investigations are on," the doctor added.
