Trina Edwards tells WAFB-TV that her husband went to an emergency room last week, and on Monday, they called an ambulance to take him to the hospital again.
She says he's improving and able to get up and move around a bit.
Edwards was governor from 1972 to 1980, 1984 to 1988 and again from 1992 to 1996.
The couple married shortly after the former governor was released from federal prison in 2011. He was sentenced to 10 years for extorting money from casino license applicants. The couple has a 3-year-old son, Eli.
Trina Edwards did not immediately return a call Tuesday from The Associated Press.
