TRS President K Chandrasekhar is on a fast for the last six days demanding separate statehood for Telangana.
The Doctors at the Nizam's Institute of Medical Sciences shifted him to the ICU at around 2 pm today as the sodium levels in his body dropped significantly.
Praja Rajyam Party president K Chiranjeevi called on KCR at the NIMS and appealed to him to end his indefinite fast.
"He has, however, rejected my plea and said he would continue his fast till the Telangana statehood issue is resolved," Chiranjeevi later told media.
Chiranjeevi appealed to the state and Central governments to immediately take an appropriate decision on Telangana.
The Politburo of TRS, which had an emergency meeting here today, called a 48-hour bandh across the region from Monday.
