"Sharif will undergo a routine medical check-up and spend some time with his grandchildren there," an official from his office said today.
He said there is no serious issue with the Prime Minister but he needed a check-up which was overdue for quite some time.
Sharif had originally planned to go to Turkey today to attend a meeting of the Organization of Islamic Conference (OIC) but changed the plan and now president Mamnoon Hussian is expected to represent Pakistan in Turkey.
The Prime Minister and his family have dismissed allegations of money laundering and denied any wrongdoing but the opposition is demanding an independent probe.
