Also known as: Sepsis / Septic Shock
Sepsis is a life-threatening medical emergency where the body's response to infection causes widespread inflammation and organ damage. Without rapid treatment, it can progress to septic shock and death.
Sepsis affects approximately 49 million people worldwide each year and causes an estimated 11 million deaths, accounting for nearly 20% of all global deaths. It is the leading cause of death in hospitalized patients and a major contributor to ICU admissions.
Sepsis occurs when the body's immune response to infection becomes dysregulated, causing widespread inflammation that damages the body's own organs and tissues. Any infection can trigger sepsis, but the most common sources are pneumonia, abdominal infections, urinary tract infections, and skin infections.
The condition exists on a spectrum: sepsis (infection with organ dysfunction), severe sepsis, and septic shock (sepsis with dangerously low blood pressure despite fluid resuscitation). Each hour of delay in antibiotic administration increases mortality by approximately 7-8%.
Survivors of sepsis frequently experience long-term complications including cognitive impairment, physical disability, psychological problems (PTSD, depression, anxiety), and increased susceptibility to future infections. This constellation of effects is known as post-sepsis syndrome.
People with Sepsis often experience the following symptoms.
Confusion, disorientation, or decreased level of consciousness. In older adults, new confusion may be the most prominent or only initial sign of sepsis.
Rapid heart rate (tachycardia), low blood pressure (hypotension), and rapid breathing (tachypnea). In septic shock, blood pressure remains low despite adequate fluid resuscitation.
High fever (above 38.3°C) or hypothermia (below 36°C). Hypothermic sepsis may carry a worse prognosis and is more common in the elderly and immunocompromised.
Decreased urine output (kidney), jaundice (liver), mottled or cold extremities (circulation), low platelets and abnormal clotting (blood), and elevated lactate levels indicating tissue hypoperfusion.
Certain factors may increase your likelihood of developing Sepsis.
Common approaches to managing sepsis. Always consult a healthcare provider for personalized treatment.
Broad-spectrum intravenous antibiotics should be administered within 1 hour of sepsis recognition. Antibiotics are narrowed once the causative organism is identified through blood cultures.
Intravenous crystalloid fluids (30 mL/kg initial bolus) to restore circulating volume and improve organ perfusion. Fluid responsiveness is assessed continuously.
Norepinephrine (first-line) and other vasopressors to maintain adequate blood pressure when fluids alone are insufficient. Administered through a central venous catheter in an ICU setting.
Identification and treatment of the infection source — drainage of abscesses, removal of infected devices, surgical debridement, or other interventions to eliminate the focus of infection.
Sepsis is identified using the SOFA (Sequential Organ Failure Assessment) score: suspected or confirmed infection plus acute increase of 2 or more SOFA points. qSOFA (quick SOFA) screening: altered mental status, respiratory rate 22 or higher, and systolic blood pressure 100 mmHg or lower. Blood cultures, lactate level, complete blood count, and organ function tests are essential.
Seek emergency medical care immediately if someone with an infection develops confusion, rapid breathing, extreme pain, feels like they might die, or has cold, clammy, or mottled skin. Sepsis is a medical emergency — every hour of delayed treatment increases mortality.
Steps that may help reduce the risk of developing or worsening sepsis.
Vaccination (influenza, pneumococcal, and other recommended vaccines)
Proper wound care and hand hygiene
Prompt treatment of infections
Awareness of sepsis signs, especially in high-risk individuals
If left untreated or poorly managed, sepsis may lead to:
Yes. With early recognition and aggressive treatment, many patients survive sepsis. However, mortality remains approximately 25-30% for sepsis and 40-50% for septic shock. Speed of treatment is the single most important factor.
Up to 50% of sepsis survivors experience post-sepsis syndrome, which may include chronic fatigue, muscle weakness, cognitive difficulties, depression, anxiety, and PTSD. Recovery may take months to years.
Yes. While people with weakened immune systems and chronic diseases are at higher risk, sepsis can develop in previously healthy individuals from any infection, including common ones like urinary tract infections or skin infections.
