Dangerous blood poisoning: What happens during sepsis?

Sepsis - commonly known as blood poisoning - is one of the most dangerous diseases of all. It occurs when bacteria, viruses or fungi trigger an infection and the body's defenses can no longer get the inflammation under control. If it is not treated immediately, this disease ends in organ failure and death.

Small injuries should not be underestimated, they can also lead to sepsis.

The immune system fails in sepsis

Sepsis always starts with a local infection. This can be an inflamed mosquito bite or a cut on the finger. From there, the pathogens spread through the body via the bloodstream. The organism reacts with an inflammation that gradually affects all organs.

The symptoms are similar to those of flu

Blood poisoning is more common than breast cancer - around 180,000 patients contract it every year. Half of those affected die from it. This is comparable to the mortality rate for heart attacks. The symptoms initially resemble those of flu: fever and chills - which is why it is not always recognized immediately. If pain and shortness of breath are added or the temperature drops sharply, you should see a doctor immediately. Sepsis is treated with antibiotics.
