Bacteremia is a medical condition characterized by the presence of bacteria in the bloodstream. This can occur when bacteria enter the bloodstream through various means, such as infections, surgical procedures, or injuries. It can lead to serious complications, including sepsis, a life-threatening response to infection. Symptoms of bacteremia may include fever, chills, rapid heartbeat, and low blood pressure. Diagnosis typically involves blood tests to identify the bacteria present. Treatment usually requires antibiotics to eliminate the infection and may involve hospitalization, depending on the severity of the condition.
