The Vatican typically restricts information about the health of popes, citing their privacy. The Holy See only confirmed that Pope John Paul II suffered from Parkinson's disease after he died.
Pope Benedict XVI enjoyed robust health during his seven-year pontificate, only missing a scheduled appearance after he broke his wrist in a fall in 2009.
Francis doesn't enjoy such good health. Jorge Mario Bergoglio, as he was known then, had wanted to be a missionary as a young priest but was counseled against it by his superior in Argentina because of the toll it would have taken on his frail health.
To this day, Francis speaks softly barely over a whisper and doesn't sing.
The Vatican's no. 2, the secretary of state, Archbishop Pietro Parolin, has been recovering for a month from unspecified urgent surgery that made him a no-show at his own welcome ceremony Oct. 15.
The Vatican has yet to reveal what has been ailing Parolin, except to say he was treated by the hospital's hepatobiliary department; the body's hepatobiliary system refers to the liver, gall bladder and bile ducts.
Officials have said Parolin, 58, is expected in Rome on Saturday.
