The Moroccan royal palace says a doctor has ordered King Mohammed VI placed in convalescence for five days for a digestive infection.
A palace statement carried by the state news agency MAP cites palace doctor Abdelaziz Maauni as saying the infection poses "no concerns for his health".
MAP says the king has a rotavirus infection with acute dehydration.
Wednesday's statement provided no other details.
The illness comes while Mohammed VI and most Moroccans are observing the holy month of Ramadan, when observant Muslims refrain from eating and drinking from sunrise to sunset.
The 45-year-old king recently marked 10 years as monarch of this North African country allied with the United States and known for its moderate brand of Islam.
