Heather O’Rourke died from congenital intestinal stenosis (a narrowing of the intestine) that led to a severe bowel obstruction, causing infection, septic shock, and cardiac arrest at age 12.

Quick Scoop: What Did Heather O’Rourke Die From?

Heather O’Rourke, the child star from the Poltergeist movies, passed away on February 1, 1988, after a sudden and catastrophic medical crisis. Doctors later ruled that she had a congenital stenosis of the intestine—a birth defect where part of the intestine is abnormally narrow—which caused a blockage, infection, and ultimately septic shock and cardiac-pulmonary arrest.

The Medical Chain of Events

  • She had a congenital intestinal stenosis , meaning the narrowing had likely been present since birth but had gone undiagnosed.
  • This narrowing led to a bowel obstruction , stopping normal passage of intestinal contents.
  • The obstruction triggered a severe infection inside the abdomen , which allowed bacteria and toxins to enter the bloodstream.
  • That infection caused septic shock , a life-threatening condition where blood pressure collapses and organs begin to fail.
  • She then suffered cardiac and pulmonary arrest (her heart and breathing stopped) and could not be revived despite emergency surgery and prolonged resuscitation efforts.

Was There Misdiagnosis?

Reports and later write-ups note that Heather had been treated for other conditions before her death, and at one point doctors believed she had Crohn’s disease. After she died, her mother pursued a wrongful-death lawsuit, arguing that earlier images actually showed a bowel obstruction that should have been surgically treated and might have saved her life. This has fueled ongoing discussion in articles and forums about whether delayed or incorrect diagnosis contributed to how quickly everything turned fatal.

How It’s Described in “Latest News” and Forums

Recent explainer articles and fan pieces typically summarize her death this way: a misdiagnosed or undetected intestinal problem led to a sudden bowel obstruction, septic shock, and cardiac arrest. Forum discussions often focus on how young she was, how “normal” flu-like symptoms rapidly escalated, and how misdiagnosis of gastrointestinal issues can have tragic consequences. Despite the rumors that often circulate around young celebrities, the consistent official line is that her death was due to congenital intestinal stenosis complicated by septic shock and cardiac arrest.

Key Facts at a Glance
