It's a serious condition and you may know of it as "blood poisoning", but it actually has a name: Sepsis. 

Sepsis is a life-threatening condition that happens when your body's immune system stops fighting an infection and begins to cause injury and damage to tissues and organs.

According to the official Sepsis website, the condition kills approximately 258,000 people in the United States every year, or one person every two minutes.

Health officials say it's been named the most expensive inpatient cost in America. 

"Sepsis Alliance, the nation’s leading sepsis patient advocacy group, is calling attention to a recent U.S. government study that reveals annual costs for treating sepsis in hospitals have increased over $3.4 billion over a two-year period," according to the Sepsis website. "The study, which analyzed billings from 2013, revealed that sepsis accounts for nearly $24 billion in annual costs, making it the most expensive condition to treat in the entire U.S. healthcare system."

September is Sepsis Awareness Month. Dr. Andy Elsberg at Providence joined KTVA 11 Evening News on Wednesday to help educate Alaskans on this issue.
