Keaton was reportedly found unresponsive at her Brentwood home in California, where first responders arrived following an emergency call early that morning. She was transported to a local hospital, but sadly, she did not survive.

At this stage, there is no confirmed medical reason or official cause linked to her passing.
There was at least one emergency response at her Brentwood home early that morning — the Los Angeles Fire Department responded to a medical call around 8:08 a.m. local time and transported someone to hospital. Reporters say the patient was likely Diane. But again: no official details on what led to her passing.

Health clues & past battles

Since we don’t have a confirmed cause, some are looking back at Diane’s health history for context, though there’s no evidence linking them directly to her death.

Skin cancer and sun damage: Diane was open about her experience with skin cancer, which she faced in her 20s.She later dealt with recurring skin issues, and once admitted she’d neglected sun care in earlier decades.

Bulimia or eating disorder: Throughout her life, Diane also spoke candidly about her struggle with bulimia. She described extreme binge-and-purge patterns in her earlier days, eventually entering recovery.

However, and this is important, no credible sources say her death was caused by cancer, bulimia, or any other disclosed illness. The timing and specifics remain unknown.

How her final months reportedly looked

Sources close to her say Diane’s health “declined very suddenly” in the last few months. She wasn’t seen walking her dog as much, which was once a daily ritual. And in March she listed her beloved “dream home” for sale, a move that surprised many, since she had lived in it for years. Friends say even longtime pals were unaware of her condition, she was keeping things very private in her final stretch.

Diane Keaton’s death has sent waves of grief through Hollywood and beyond. Colleagues, fans, and friends are remembering her as “a complete original,” “hilarious,” and “without guile.” She leaves behind two sons (whom she adopted later in life), a legacy of films spanning decades, bold style choices, and a fearless commitment to being herself.
