In saddening news, ABC News has confirmed that actor Patty Duke has died at the age of 69.

Many fans might be wondering how Patty Duke died, and her rep, Mitchell Stubbs confirmed to ABC News that the cause of death was "sepsis from a ruptured intestine."

While there weren't reports of Duke battling any illnesses before her death, a tweet on her official Twitter on March 1 indicated that she had been unusually absent from social media. Although she did not specify the reason, she sounded positive:

Duke was celebrated not only for her acting credits, but for her role as a mental health advocate after she revealed in 1982 that she was diagnosed with bipolar disorder. She was also a devoted mother to her three sons, with Mackenzie and Sean Astin following in her footsteps to become actors themselves.
