Former president George HW Bush has been hospitalised for apparently partying "too hard" according to an email sent out by his chief of staff.

The 93-year-old was taken to hospital in Maine for low blood pressure and fatigue on Sunday.

CNN reported that a tongue-in-cheek email sent out by Jean Becker, the former president's chief of staff, to family and friends read: "I guess he partied too hard with the American Legion yesterday. Darn it."

She added that President Bush was "taken to Southern Maine Health Care today after experiencing low blood pressure and fatigue".

"He likely will remain there for a few days for observation. The former president is awake and alert, and not in any discomfort."

The former president's wife, Barbara Bush, died in April aged 92. The pair had been married for 73 years, and had six children, including eldest son George W Bush who would go on to become the president eight years after his father's term ended.

Concern grew for President Bush's health after he was hospitalised the day after his late wife's funeral, however he was then released after 13 days.

He has been confined to a wheelchair in recent years due to being diagnosed with vascular Parkinsonism, a rare condition that mimics Parkinson’s disease.

Despite his advanced age and health conditions, the former president continues to make public appearances, including a visit to The American Legion last week in which in met with former soldiers.
