He entered King Faisal Specialist Hospital in the coastal city of Jeddah on Saturday "to conduct some medical examinations", according to an official report, citing a royal court statement.
"May God preserve the Custodian of the Two Holy Mosques and may he enjoy health and wellness," the statement said.
King Salman underwent surgery to remove his gall bladder in 2020.
He was most recently hospitalised in March, for what state media described as "successful medical tests" and to change the battery of his pacemaker.
Under his rule, Saudi Arabia has launched ambitious economic reforms for a post-oil era and given more rights to women, while adopting a more assertive foreign policy.
