UK doctor clarifies the mystery behind death of Jayalalithaa

Beale was flanked by P Balaji of Madras Medical College and K Babu of Apollo Hospitals, who had signed in election forms on which her thumb impression was taken.

This was for nominating AIADMK candidates for elections to two seats and bypoll to one segment last year.

Beale clarified that it was possible for sepsis, the body's response to infection, to spread fast and damage other organs though Jayalalithaa showed signs of recovery during her 75-day stay at the Apollo Hospitals.

On the day she was admitted "she became short of breath at home and very short of breath when the ambulance brought her to the hospital...There was an infection resulting in damage to organs and contributing to shortness of breath".

He said at that time "it was not clear" what the source of infection was "but subsequent tests showed there was indeed infection in her blood".

"So bacteria were going from the blood and that was where the infection was identified and resulted in her general poor condition," he said.

It was known that Jayalalithaa was suffering from diabetes and high blood pressure, he said.
