It causes inflammation across large areas of the body and can damage tissue and organs. Sepsis needs emergency medical treatment in a hospital. Septic shock is sepsis that causes extremely low blood pressure, which limits blood flow to the body. It can cause death. Most of the time, sepsis is caused by a bacterial infection. It can also be caused by a fungal or viral infection. Infections that can lead to sepsis include: Sepsis can occur in people of any age. But it's more common in infants, older adults, people who have health conditions that make it hard to fight infection, and people who are pregnant. Sepsis can develop very quickly. Sepsis is serious and causes many different symptoms. Symptoms may include breathing problems, a fast heartbeat, cool clammy skin, a fever, shivering, or feeling very cold. Other symptoms may include confusion, pain, and feeling faint (from low blood pressure). If you have symptoms of sepsis, go to the hospital right away for medical treatment. Your doctor will ask you about your symptoms and do tests, including blood tests. You may get an imaging test, such as an X-ray or CT scan, to help find the infection. Sepsis is treated with medicines to fight the infection that led to sepsis. Machines will track vital signs, including temperature, blood pressure, breathing rate, and pulse rate. You'll get fluids through a vein (intravenous, I.V.). You may also get other medicines to help with your blood pressure and pulse. You might need to be treated in an intensive care unit (ICU) for several days or weeks so you can be closely monitored. Equipment in the ICU can support your body. That includes your breathing, blood flow, fluids, and help for organs like the kidneys and heart. If you need help breathing, a ventilator may be used.
