Doctors at government-run Osmania General Hospital said Jaganmohan Reddy refused to take intravenous fluids. After examining him, the doctors had advised him to take the intravenous fluids as the glucose level in the body had come down.
Jagan, as the MP from Kadapa is popularly known, is on fast for the last six days to oppose bifurcation of Andhra Pradesh without ensuring justice to all regions.
The MP, who launched the fast in jail Sunday, was shifted to hospital around midnight amid tight security. Police baton charged Jagan's supporters who had gathered in large numbers and wanted to enter the hospital.
Sporting red T-shirt and black trousers and looking weak, Jagan got down from police vehicle and preferred to walk into the hospital, though he was offered a wheel chair.
Jagan's mother Y.S. Vijayamma, wife Bharathi and other family members rushed to the hospital to meet him. Vijayamma demanded that Jagan be shifted to NIMS Hospital.
Large number of policemen and personnel from paramilitary forces were deployed outside Osmania Hospital. Only patients and those having valid ID cards were being allowed inside.
Jagan is in jail since May last year in a disproportionate assets case.
