The Chief Minister of Tamil Nadu J Jayalalithaa is being treated for fever and dehydration.
The Chennai hospital where Tamil Nadu Chief Minister J Jayalalithaa has been admitted for the last seven days has released a medical update on her health, saying she has "responded well" to treatment.
"Necessary evaluation tests are being carried out. The Honourable Chief Minister has been advised few days stay in the hospital," read a statement by the Apollo hospital, Chennai.
The bulletin comes after after days of silence - a gap that had left Ms Jayalalithaa's supporters worried. Earlier today, her party, the AIADMK, had assured supporters that she is well.
The 68-year-old Chief Minister is being treated for fever and dehydration. A government statement on Tuesday had said that from her hospital bed, she had been monitoring the Cauvery water sharing issue and held meetings with her ministers. Earlier today, she had delivered a blistering criticism of Karnataka's move to withhold Cauvery water despite the order of the Supreme Court.
"Chief Minister Jayalalithaa is under observation and absolutely fine. Soon she will be discharged and start her regular duty," said the AIADMK's C R Saraswathi.
Talking to NDTV, she had detailed how Ms Jayalalithaa has held meetings with her officials and ministers in hospital, including dictating the speech to be made in Delhi on her behalf.
The AIADMK has said that Ms Jayalalithaa is in hospital only for observation now and is likely to be discharged on Friday.
In their last update on Sunday, doctors had dismissed rumours that Ms Jayalalithaa was so ill that she would have to be be taken abroad for treatment.
Opposition leader S Ramadoss of the PMK has suggested that the state government release a photograph or video of the Chief Minister to quell speculation that she is very unwell.
The luxury hospital has turned a fortress, with Ms Jayalalithaa's cabin being on its second floor. Bureaucrats and hospital staff have come under scrutiny to ensure confidentiality.
