Sepsis is blood poisoning that kills, and diabetic foot infections are a common trigger. Bacteria from infected wounds enter your bloodstream through damaged tissue. Once in your blood, bacteria multiply rapidly and release toxins throughout your entire body. Your immune system overreacts, causing widespread inflammation that damages organs. Blood pressure drops dangerously low as vessels dilate. Organs like kidneys, liver, and lungs begin failing from lack of blood flow. Without emergency treatment, septic shock causes death within hours. Any diabetic foot wound showing spreading redness, fever, or confusion needs immediate emergency care.
