In her 2018 memoir, "My Love Story," the Grammy Award-winning singer stated that, not long after their wedding, she started to experience a number of health issues.
"I've been on such a wild roller-coaster in the four years since my wedding that even I have difficulty keeping my medical catastrophes straight," she wrote, going to explain she experienced a stroke just three months later.
Turner's history with high blood pressure, something she had recently revealed she was first diagnosed with in 1978, also left her with severe kidney problems.
In 2016, Turner's husband Erwin Bach offered to donate one of his kidneys to his wife, which took her by surprise.
"He said he didn't want another woman, or another life," she recalled in her memoir. "Then he shocked me. He said he wanted to give me one of his kidneys."
The transplant took place the following year. and Turner opened up about the aftermath in a blog post for Show Your Kidneys Love in March this year.
She said that her body tried to reject the new kidney and "required more hospital admissions." At the time of writing, Tuner said that the "problems are still not quite resolved."
