McGrath said Barbara Bush had been sick for some time, and was tired of treating her illness at home.
The 92-year-old Bush has been hospitalized several times over the last few years, including a stay at a Portland, Maine medical center in July 2015, when the former president broke a vertebrae in his neck while at his summer home in Kennebunkport.
Bush was also hospitalized at Houston Methodist Hospital in December 2014 after experiencing shortness of breath, his spokesman said.
