LONDON (AP) -- The new pope has daunting challenges ahead
ranging from the church sex abuse scandal to reinvigorating the flock.
And Francis will have to do it all with just one lung.
The
Argentine pontiff lost the greater part of one lung to a teenage
infection. "He feels it today," says his authorized biographer Sergio
Rubin. "He's a little bit slowed by it, but he's OK."
Doctors
said that losing one lung doesn't necessarily compromise the pope's
health or reduce his life span, though it means no strenuous exercise
since he no longer has as much air capacity as people with two lungs.
"He probably wouldn't be able to run marathons, but I don't think that
would be on his schedule," said Dr. Peter Openshaw, director of the
Centre for Respiratory Infection at Imperial College London. "Having one
lung should be enough as long as there is no other disease in that
lung."
Openshaw didn't think a papal schedule
would be too taxing for Francis' one lung, though he noted the pope's
rib cage might look slightly unusual. "His X-ray will probably look
rather alarming, but understandable once you know he only has one lung,"
he said.
Openshaw said Francis' existing lung
would probably have expanded to fill the space left by the missing one,
and that his rib cage would have shrunk slightly in size. His diaphragm
may also have moved up slightly higher than normal. But none of those
changes should affect Francis' normal activities, he said.
He
said the pope's remaining lung should be able to compensate for the
missing one, similar to how parts of the brain may pick up functions of
other regions damaged by a stroke.
"The other
lung can gain capacity but there will be limits," he said, comparing it
to a car engine that now runs slightly slower. "You may not be able to
accelerate as hard but it still works just as well."
Experts
said it would be rare nowadays to remove a lung. Antibiotics would be
used to treat most lung infections including tuberculosis, though part
of the organ might be removed to treat advanced lung cancer.
Back
when Francis had his lung removed, the available antibiotics weren't as
powerful. "In the past, doctors used to try all kinds of strange things
to try to treat lung infections," said Dr. Jennifer Quint, a
respiratory expert at London's School of Hygiene and Tropical Medicine.
She said physicians even used to stick ping pong balls into peoples'
lungs in an attempt to starve the lung of oxygen, to kill the bacteria.
Quint said the fact that Francis appears so fit and healthy at 76 bodes well for his future.
"If
he were going to have any major complications from the surgery (to
remove the lung), he would have had them by now," she said. She said
Francis' main challenge will be to keep his remaining lung healthy. "I
would recommend a yearly flu vaccination and an occasional pneumonia
vaccine to avoid infection," she said.
Jeremy
Ward, a professor of respiratory physiology at King's College London,
said he was only mildly concerned about the pope's health - unless he
gets sick.
"If he gets any sort of infection,
it could be much more serious in him than in someone else with two
lungs. ... That could make him susceptible to pneumonia, which would be
very dangerous for him." he said, adding it would either take the pope
longer to recover or debilitate him.
Still,
Ward didn't think Francis would have to take any unusual measures to
avoid getting sick and faced the same problems as all elderly people.
"Unfortunately
as you get older, nothing works as well as it should," he said. "He
will have to deal with that like everybody else."
