What was Diane Keaton’s cause of death?
In a statement shared with People, Diane’s family confirmed she passed away due to pneumonia.
“The Keaton family are very grateful for the extraordinary messages of love and support they have received these past few days on behalf of their beloved Diane, who passed away from pneumonia on October 11,” the statement read.
“She loved her animals and she was steadfast in her support of the unhoused community, so any donations in her memory to a local food bank or an animal shelter would be a wonderful and much appreciated tribute to her.”
A source previously revealed that Diane’s health “declined very suddenly.”
According to a 911 recording obtained by TMZ, the Los Angeles Fire Department responded to Diane Keaton’s home just after 8 am on Saturday following reports of a “person down.” She was taken to a nearby hospital, where she was pronounced dead.
Diane Keaton’s health struggles
Over the years, Diane has suffered from multiple skin cancers. She battled basal cell carcinoma, a type of skin cancer she described as “tricky,” noting a strong family history of the disease.
In a 2015 interview with the Los Angeles Times, she said, “I remember my Auntie Martha had skin cancer so bad they removed her nose. My father had basal skin cancer, and my brother had it.” Decades later, she was also diagnosed with squamous cell carcinoma and underwent multiple surgeries.
In addition to skin cancer, Keaton spoke openly about her struggle with bulimia. She told Dr Oz in 2014 that the eating disorder began after she was asked to lose weight for a Broadway role.
“All I did was feed my hunger, so I am an addict,” she said. “It’s true. I’m an addict in recovery, I’ll always be an addict. I have an addictive nature, to me.”
She described a typical binge as including “a bucket of chicken, several orders of fries with blue cheese and ketchup, a couple of TV dinners, a quart of soda, pounds of candy, a whole cake and three banana cream pies.”
Public reaction to her passing
Diane’s career spanned more than five decades, with memorable performances across comedy, drama, and romance. She won an Academy Award for Best Actress for her role in Annie Hall. She also received critical acclaim for films including Reds, Marvin’s Room, Something’s Gotta Give, and Book Club. Beyond acting, she was known for her distinctive personal style, photography, and creative pursuits.
