Former Gov. Ben Cayetano was released from the hospital Tuesday, one day after checking himself into the emergency room for undisclosed reasons.

“I’m fine,” Cayetano said by telephone. 

He declined to say why he went to the emergency room nor did he specify where. “I’m a retired politician now,” he said. “This is a private matter.”

Cayetano recently wrapped up a hard-fought campaign for mayor in which he finished second to Mayor-elect Kirk Caldwell by a 54 percent to 46 percent vote.

The former two-term governor also was hospitalized for three days in August — the week of the primary election — with a bleeding ulcer. Doctors examined the affected area of his stomach and cauterized a blood vessel to prevent further bleeding. No further treatment was needed and Cayetano resumed the campaign that week.

He suffered a similar event in 1997, as governor, and was hospitalized for five days.
