Mrs Tharoor, said doctors at Thiruvananthapuram's super-speciality Kerala Institute of Medical Sciences (KIMS) Hospital, had been admitted for an executive check-up from January 12 to 14 as she had been unwell. They said no test reports so far had indicated that she was critically ill.
"We did not see any finding based on the investigations for a sudden demise," said a KIMS doctor. He said she had been given necessary medication for her illness. Doctors have not shared what ailment Mrs Tharoor had, but she had told NDTV two days ago that she was being treated for tuberculosis.
The doctors said that Sunanda Tharoor was cheerful and comfortable during her stay at the hospital and that her husband union minister, Shashi Tharoor, was with her all the time. (Read: Unseemly Twitter war involving Tharoors)
The couple returned to Delhi on Wednesday and planned to go back to Kerala again in a few days to decide on the course of treatment once all test results were in, PTI has quoted sources in Thiruvananthapuram as saying.
Mrs Tharoor was found dead in a five-star hotel room by her husband on Friday evening.
The couple was seen together earlier this week at a conclave and a religious festival at the Padmanabhaswamy temple in Mr Tharoor's constituency.
The Kerala Police stepped up security at Mr Tharoor's constituency office in the heart of the city and at his residence as soon as her death was reported.
The opposition in Kerala, CPI(M) has demanded a detailed inquiry into Mrs Tharoor's death.
