Kauvery Hospital, where DMK leader and veteran politician M Karunanidhi is currently admitted, released a statement on Tuesday evening stating tha the 94-year-old needs to be kept for an extended period 'due to age-related overall decline in his health.'

Karunanidhi was admitted to the Intensive Care Unit (ICU) of the hospital on Saturday after his blood pressure dropped. His health deteriorated on Sunday evening, leading to well-wishers and party cadres flocking to the hospital. And although his vital signs have normalised, he remains under close watch of an expert team of doctors. "An extended period of hospitalization will be necessary due to age-related overall decline in Karunanidhi's general health, altered liver functions and haematological parameters," the hospital statement on Tuesday informed. "He continues to maintain his vital signs with active medical support."
