Saudi King Salman had medical examinations on Sunday after having fever and joint pain, and had a lung infection diagnosed, the royal court reported.
After the tests at the Royal Clinics at Al Salam Palace in Jeddah, the medical team advised that King Salman should undergo a programme of treatment and antibiotics until the infection cleared up.
He was admitted to hospital last month for a routine check-up.
The king chaired last week's Cabinet meeting in Jeddah where he reviewed the kingdom's plans to receive more than two million Muslims for the annual Hajj.
In May 2022, he was admitted to the same hospital and underwent a colonoscopy, and the “result was sound", the Saudi Press Agency reported.
He was admitted to the hospital in March 2022, where he underwent medical tests and doctors changed the batteries in his pacemaker.
In July 2020, King Salman had a successful operation to remove his gall bladder after inflammation.
King Salman, 88, has been on the throne since 2015. His son, Mohammed bin Salman, 38, was named Crown Prince in 2017.
