Pope Fran­cis was hos­pi­tal­ized Fri­day to treat a week­long bout of bron­chi­tis and un­der­go di­ag­nos­tic tests, the Vat­i­can said, con­firm­ing the lat­est is­sues with the 88-year-old’s pon­tiff’s health that forced him to can­cel his agen­da through Mon­day at least.

Fran­cis has com­plained of breath­ing trou­ble and was di­ag­nosed with bron­chi­tis Feb. 6, but had con­tin­ued to hold dai­ly au­di­ences in his Vat­i­can ho­tel suite. He at­tend­ed his gen­er­al au­di­ence Wednes­day and presided at an out­door Mass on Sun­day. But he had hand­ed off his speech­es for an aide to read aloud, say­ing he was hav­ing trou­ble breath­ing.

On Fri­day, he ap­peared bloat­ed and pale dur­ing the hand­ful of au­di­ences he held be­fore go­ing to the hos­pi­tal. The bloat­ing ap­peared to in­di­cate that the med­ica­tion he was tak­ing to treat the lung in­fec­tion was mak­ing him re­tain wa­ter.
