Shiv Sena supremo Bal Thackeray, who was admitted to Lilavati Hospital in suburban Bandra two days ago, was "fine", the doctor treating him said.
"He is fine, but will be kept in the hospital for another two-three days," said chest physician Dr Jalil Parkar.
He refused to specify the exact ailment. "I would not discuss his medical issues," he said.
Earlier in the day, Bharatiya Janata Party president Nitin Gadkari met the 86-year-old Shiv Sena patriarch to inquire about his health.
Sena sources had said that Thackeray was hospitalised only for a routine check-up.
His son and Sena executive president Uddhav Thackeray underwent angioplasty procedure at the same hospital a few day ago.
