Thailand's King Bhumibol Adulyadej is back on his feet and recovering well after a hernia operation, the Bureau of the Royal Household has said.
King Bhumibol is the world's longest reigning monarch
The Bureau said the monarch's temperature, heart, blood pressure and respiratory system were all normal.
There was no word on when the King would be able to leave hospital.
The 75-year-old monarch was diagnosed with a hernia problem on his right side in November, which was found to have worsened by January.
King Bhumibol - the world's longest reigning monarch - has had a series of health scares in recent years.
Last June he had a successful operation to treat a hernia on his left side, and
in February 2002 he was admitted to hospital for prostate surgery.
King Bhumibol has been on the throne since 1946. He is regarded highly by his people, and some even see him as a god-like figure.
He has been a powerful force for unity, despite the political upheavals seen in Thailand's recent history.
