Manny Pacquiao in hospital with stomach ulcer

World welterweight champion Manny Pacquiao of the Philippines has been admitted to hospital to treat a mild stomach ulcer and allow him to rest after campaigning for the May 10 congressional elections.

Pacquiao's chief of staff, Jayke Joson, said that doctors discovered the 31-year-old boxer had an ulcer during a routine check-up and his family convinced him to stay on in a suburban Manila hospital for a few days.

Pacquiao's mother, Dionisia said her son was well and may be discharged from the hospital early this week.

Pacquiao won a seat in the Philippine's powerful House of Representatives, which he will assume on June 30.
