Pope Francis appointed a new personal doctor on Wednesday, several weeks after the death from Covid-19 of the previous holder of the post.
The 84-year-old pontiff picked Roberto Bernabei, an expert in health care for the elderly, as his physician, the Vatican said in a statement.
Bernabei, 69, leads the geriatrics and rehabilitative medicine department at Rome's Gemelli, the Catholic hospital where popes are traditionally treated.
The last papal doctor, Fabrizio Soccorsi, died aged 78 on January 9 of Covid-19-related pulmonary complications, following a hospitalisation for cancer.
Francis is believed to be in relative good health, despite having had part of his lung removed when he was a young man after developing pleurisy.
Last month he cancelled several events due to a bout of sciatica, a chronic nerve condition that causes hip pain and makes him walk with a slight limp.
Also in January, the pope received the coronavirus vaccine alongside his predecessor, former pope Benedict XVI.
