The 61-year-old singer, whose frail appearance has caused concern among Britain`s media, was hospitalised last week after making an emergency call from his house in Thame, south west England, according to the tabloid newspaper.
Robin`s twin brother Maurice died in 2003 from complications resulting from a twisted intestine, and younger brother Andy died in 1988 following a battle against cocaine addiction.
Older brother and fellow Bee Gee Barry has returned to Britain along with 91-year-old mother Barbara, according to the report.
The British-born brothers scaled the heights of the pop world in the 1970s with disco hits "Stayin` Alive" and "Night Fever", and notched up over 200 million record sales during a career which has spanned seven decades.
Robin was forced to cancel several appointments last month, including one with British Prime Minister David Cameron, after he was hospitalised with severe stomach pains.
His spokesman said the family did not want to comment on the reports.
