Pope Francis is being held in hospital for several days with a lung infection, the Vatican said.
The pontiff, 86, experienced breathing difficulties in recent days, a statement released on Wednesday evening said.
"Pope Francis is touched by the many messages received and expresses his gratitude for the closeness and prayer," the Vatican said.
Hours earlier, it said the Pope had gone to Rome's Gemelli Hospital for a "scheduled check-up".
Earlier in the day he took part in the weekly general audience and appeared to be in good health.
Pope Francis suffers from diverticulitis, a condition that can infect or inflame the colon, and had an operation in 2021 to remove part of the organ.
This year, he said the condition had returned and that it was causing him to put on weight, but that he was not overly concerned. He did not elaborate.
He also has a problem with his knee and alternates between using a cane and a wheelchair in his public appearances.
Pope Francis said last year that he preferred not to have surgery on his knee because he did not want a repeat of long-term side-effects from anaesthesia he suffered after the 2021 operation.
Last July, returning from a trip to Canada, the Pope acknowledged that his advancing age and his difficulty walking might have ushered in a new, slower phase of his papacy.
But since then, he has visited Kazakhstan and Bahrain, and made a gruelling trip last month to the Democratic Republic of the Congo and South Sudan.
Pope Francis also said this year that he has no plans to resign any time soon and that if he eventually did it would be for serious heath reasons, such as if he were incapacitated.
Asked by Italian-Swiss television channel RSI in an interview broadcast on March 12 what condition would lead him to quit, he said: “A tiredness that doesn't let you see things clearly. A lack of clarity, of knowing how to evaluate situations.”

hall of shame
SUNDERLAND 2002-03
No one has ended a Premier League season quite like Sunderland. They lost each of their final 15 games, taking no points after January. They ended up with 19 in total, sacking managers Peter Reid and Howard Wilkinson and losing 3-1 to Charlton when they scored three own goals in eight minutes.
SUNDERLAND 2005-06
Until Derby came along, Sunderland’s total of 15 points was the Premier League’s record low. They made it until May and their final home game before winning at the Stadium of Light while they lost a joint record 29 of their 38 league games.
HUDDERSFIELD 2018-19
Joined Derby as the only team to be relegated in March. No striker scored until January, while only two players got more assists than goalkeeper Jonas Lossl. The mid-season appointment Jan Siewert was to end his time as Huddersfield manager with a 5.3 per cent win rate.
ASTON VILLA 2015-16
Perhaps the most inexplicably bad season, considering they signed Idrissa Gueye and Adama Traore and still only got 17 points. Villa won their first league game, but none of the next 19. They ended an abominable campaign by taking one point from the last 39 available.
FULHAM 2018-19
Terrible in different ways. Fulham’s total of 26 points is not among the lowest ever but they contrived to get relegated after spending over £100 million (Dh457m) in the transfer market. Much of it went on defenders but they only kept two clean sheets in their first 33 games.
LA LIGA: Sporting Gijon, 13 points in 1997-98.
BUNDESLIGA: Tasmania Berlin, 10 points in 1965-66

Labour dispute
The insured employee may still file an ILOE claim even if a labour dispute is ongoing post termination, but the insurer may suspend or reject payment, until the courts resolve the dispute, especially if the reason for termination is contested. The outcome of the labour court proceedings can directly affect eligibility.

UK's plans to cut net migration
Under the UK government’s proposals, migrants will have to spend 10 years in the UK before being able to apply for citizenship.
Skilled worker visas will require a university degree, and there will be tighter restrictions on recruitment for jobs with skills shortages.
But what are described as "high-contributing" individuals such as doctors and nurses could be fast-tracked through the system.
Language requirements will be increased for all immigration routes to ensure a higher level of English.
Rules will also be laid out for adult dependants, meaning they will have to demonstrate a basic understanding of the language.
The plans also call for stricter tests for colleges and universities offering places to foreign students and a reduction in the time graduates can remain in the UK after their studies from two years to 18 months.
