Deputy Collector Sachin Kalantre told mediapersons that Patil "has developed blockages" and doctors were attending to him.
Patil, who inaugurated the centenary celebrations of Hanuman Vyayam Prasarak Mandal (HVPM) here this morning, where former President Pratibha Patil was also present, felt uneasy and took some tablets while delivering his address.
He was later taken to Circuit House where his doctor Anil Meshram administered him first aid and was shifted to Dr Vijay Bhatkar's hospital.
"Patil vomitted and sweated a lot," doctors said.
The Collector said Patil's son and Maharashtra's Minister of State for Home Satej Patil will be reaching here this evening and subsequently they will decide on shifting him either to Mumbai or Nagpur.
Besides the centenary celebrations of HVPM, Patil ,an eminent educationist from Maharashtra, was scheduled to attend a couple of other functions in Amravati.
He was supposed to have lunch at the residence of Pratibha Patil.
77-year-old Patil, has founded a number of educational institutes in Maharashtra including the D Y Patil college of Engineering and Technology at Kolhapur and D Y Patil College of Engineering in Pune in 1984. He received the Padma Shri award in 1991 for social work.
