Everyone may develop an infection at some point in life. But while many infections are cleared up by our immune system or with help from medication, others can progress to a life-threatening complication known as sepsis, notes the NHS. (1)
When you’re sick, your immune system signals the release of chemicals that increase inflammation and help stop the spread of viruses, bacteria, or fungi. In the case of sepsis, the immune system’s inflammatory response to an infection is dysregulated. This causes widespread, dangerous inflammation throughout the body that can lead to poor blood flow and blood clots, says to the Mayo Clinic. (2)
Sepsis can also lead to organ failure and death. According to an article published in December 2019 in the Yale Journal of Biology and Medicine, organs that are more likely to fail, either individually or together (called multi-organ failure), in a severe sepsis state include: (3)
- Blood system
Sepsis can progress quickly, so it’s vital to spot signs of this condition and get medical help. You can’t treat sepsis at home. It requires treatment in an intensive care unit (ICU), per the National Institute of General Medical Sciences. (4)
Signs and Symptoms of Sepsis
If you have any of the following symptoms, you may have sepsis, in mild to severe forms as the difference between sepsis and more severe forms called septic shock are not easily detected without physician evaluation: (4)
- High fever (greater than 101 degrees F) or low body temperature (below 96.8 degrees F)
- Fast breathing (in general greater than 22 breaths per minute, depends on the individual)
- Heart rate more than 90 beats per minute (bpm)
- Change in mental status; confusion or disorientation
- Low blood pressure
- Chills or shivering
- Clammy or sweaty skin
If you’re fighting an infection and notice these symptoms, don’t delay in getting medical attention. Go to the emergency room or call 911. You should also see a doctor if you have these symptoms without a known infection.
Possible Warning Signs of Sepsis in Small Children
Identifying sepsis in children can be difficult when they’re too young to express how they feel.
Signs of sepsis in newborns and infants can include any of the above symptoms, as well as these symptoms, per KidsHealth: (5)
- Changes in skin color, such as blue or pale skin
- Bulging soft spot on head
- Pauses in breathing
Sepsis in children also starts with an infection. Seek immediate medical attention if your child develops any of these symptoms while he or she is fighting an infection.
Common Questions & Answers
Causes and Risk Factors of Sepsis
Any type of infection in the body can cause this serious medical complication. But some infections are more commonly linked to sepsis than others. These include: (4)
- Urinary tract infections (UTIs)
- Skin infection
- Abdominal infections
- Blood infection
Similarly, certain germs can lead to infections that later develop into sepsis. These include: (2)
Even though sepsis can happen to anyone, some people have a higher risk, such as adults age 65 and older and children younger than 1 year old. (2)
Premature babies are also at risk for sepsis because of their weakened immune system. (5) Babies in the neonatal intensive care unit are hooked up to IVs, catheters, and other tubes. Sometimes, bacteria on the skin surface can seep into openings connecting these tubes. (2)
Having a chronic illness may also put you at a higher risk for sepsis because you are immunocompromised. (2)
An open wound, injury, or skin burn can also increase the likelihood of sepsis. (2)
How Is Sepsis Diagnosed?
Because there’s no single test to diagnose sepsis, confirming this medical condition is difficult, notes the Sepsis Alliance. (6) But with the help of blood tests and other laboratory tests, doctors can usually diagnose sepsis based on symptoms and test results.
“Doctors look for sepsis in patients who have complaints that may be caused by an infection, such as a cough, a fever, burning during urination, an elevated heart rate, faster than normal breathing, confusion, lethargy, and mottled skin,” says Kimberly Brown, MD, MPH, an ER doctor at the University of Tennessee Health Science Center in Memphis, Tennessee.
To help diagnose sepsis, your doctor will take your temperature to confirm a fever. You’ll also have your blood pressure, heart rate, and breathing rate monitored. (4)
Blood testing is also common to look for signs of an infection and to examine your organ function. Laboratory tests conducted in the hospital may include a urine test to check for a urinary tract infection. You may also have a respiratory secretion test to identify the specific germ causing an infection. And if you have an open wound, your doctor may test secretions from the wound to determine the most appropriate antibiotic, according to the Mayo Clinic. (7)
If your doctor believes that an infection originated in your gut, a computerized tomography (CT) scan, ultrasound, or magnetic resonance imaging (MRI) is used to take pictures of the inside of your body. These tests can look for abscesses or infections in your stomach, gallbladder, or ovaries.
While sepsis is life-threatening, life after sepsis is possible. There are more than 1.4 million sepsis survivors every year in the United States, per the Sepsis Alliance. (8) But some survivors have post-sepsis challenges.
For example, about 60 percent of survivors experience long-term decline in cognitive and physical function. In addition, about one-third of sepsis survivors return to the hospital within three months because of another infection or a repeated case of sepsis. (8)
During the weeks or months following your recovery, you may also experience body aches, weight loss, difficulty sleeping, hair loss, brittle nails, depression, and poor concentration, according to the Centers for Disease Control and Prevention (CDC). (9)
The duration of sepsis varies from person to person. Hospital treatment is often necessary, and depending on the severity, some people might remain in the hospital for several weeks, notes the NHS. (10) Doctors administer antibiotics upon diagnosis, which are given in the hospital or if discharged taken orally, all total for about 7 to 10 days or longer for more severe cases or multiple infections, per the NHS. (11)
Even in the case of mild sepsis, it takes times to recover and rebuild strength. Some people develop post-sepsis syndrome, characterized by feeling weak and tired for several weeks or months after completing treatment. (10)
Sepsis Treatment and Medication Options
Treatment for sepsis is based on the source and severity of the infection. The goal of treatment is to stop the infection and protect organs from failing. Per the Sepsis Alliance, treatment may include: (12)
- Antibiotics A broad-spectrum antibiotic is capable of treating several types of bacteria. You’ll receive this medication intravenously so it can get into your bloodstream faster.
- Intravenous (IV) fluids Treatment with intravenous fluids help prevent low blood pressure and promotes blood flow to your organs. Adequate blood flow can prevent organ damage and organ failure. You may receive normal saline containing sodium, or colloids that help increase blood fluid volume.
Other treatments for sepsis include, not limited to: (12)
- Corticosteroids, to help reduce inflammation and support blood pressure
- Kidney dialysis
- Oxygen therapy
- Vasopressors (constricts blood vessels and increases blood pressure)
Sometimes, surgery is necessary to address an infection for example, a large abscess or infected limb.

Prevention of Sepsis
Sepsis is preventable, whether it’s a first-time case or a recurrence. One of the best ways to protect yourself is being proactive if you have signs of infection.
“Prevention is best done by seeking medical treatment early for evaluation of a suspected infection,” warns Dr. Brown. “The more rapidly an infection is treated, the less likely it can become sepsis."
Along with quick action, the Sepsis Alliances says to take the following measures to prevent infections: (13)
Practice good hygiene. Get into a routine of washing your hands frequently throughout the day, especially before meals or before preparing food. Make a conscious effort not to touch your mouth, nose, or eyes with your hands. Also, avoid people who are sick. Teach your children the proper way to wash their hands to lower their risk of infection. Thorough hand-washing takes at least 10 to 15 seconds. (13)
Get annual vaccinations. Talk to your doctor about vaccinations to help prevent infections. These include an annual flu shot, as well as vaccinations to prevent chicken pox, tetanus, and pneumonia.
Take antibiotics as directed. If you develop an infection and you’re prescribed an antibiotic, antiviral, or antifungal, take your medication as directed and complete the full course. Don’t stop your medication just because you feel better.
Take proper care of wounds. Many cuts, scrapes, and minor burns can be treated at home. But it’s important that you clean wounds with water to remove dirt and germs, and then apply antibiotic cream. Keep the wound covered with gauze until it heals. Also, learn how to recognize signs of a skin infection. Symptoms include skin redness, skin that’s warm to the touch, discharge from a wound, and worsening pain. Seek medical attention if you suspect a skin infection.
Complications of Sepsis
Your condition can worsen when sepsis isn’t diagnosed fast enough.
“If sepsis isn’t treated, it can develop into septic shock, which leads to a drop in blood pressure and eventually death, so it should be treated as soon as possible,” says Rebecca Lee, RN, the founder of the natural health resource Remedies For Me, who is based in New York City. “The faster treatment is started, the better the outcome."
Symptoms of septic shock include the symptoms of sepsis, as well as these following conditions. Although sepsis and septic shock can present in a variety of ways, the NHS says these are commonly seen: (14)
- Dizziness or fainting
- Nausea, vomiting, or diarrhea
- Shortness of breath
- Muscle pain
- Slurred speech
- Sweaty skin
In addition to these, low blood pressure caused by septic shock can prevent blood flow to your organs. Inadequate blood flow can then lead to organ failure and tissue death. (14)
Death of soft tissue from a bacterial infection is known as gangrene. Symptoms of tissue death include numbness, severe pain, and skin discoloration. Gangrene affects the extremities and could result in amputation of a limb.
When septic shock causes permanent damage to kidneys or lungs, you may also develop respiratory problems or require dialysis. Since septic shock can also impair your immune system, you’re also at risk for another infection. (4)

Research and Statistics: How Common Is Sepsis?
If you’ve never heard of sepsis, you may think this is an extremely rare condition. But sepsis is more common than some people realize.
“It is estimated that about one million people are hospitalized annually in the United States for sepsis, and it is included in the top 10 diseases that lead to death," says Lee, and an article published in July 2017 in St. Louis Magazine concurs. (15)
Among those hospitalized with sepsis, as many as 270,000 Americans die each year, notes the CDC. (16) In addition, about 1 in 3 people who die in the hospital has sepsis. (16) The number of sepsis cases has risen in recent years. Experts haven't pinpointed the exact cause for this, but certain factors may contribute to the increase. (4)
One belief is that doctors have become more aware of sepsis, resulting in more medical professionals tracking these cases than before.
The fact that people are living longer may also play a role in the increased number of sepsis incidents. This is because the risk for chronic diseases rises with age, and sepsis is more likely to occur in those with a chronic disease. (5) Currently, the average life expectancy in the United States is 78.6 years, according to the CDC. (17)
Antibiotic resistance may also influence the prevalence of sepsis. This occurs when bacteria adapt and resist antibiotics commonly used to treat bacterial infections. As a result, antibiotics become less effective in treating infectious diseases. And when antibiotics don’t work, infections can spread and lead to sepsis. (2)
Related Conditions and Causes of Sepsis
In addition to the aforementioned infections, germs, and skin burns, having certain chronic conditions could put you at a higher risk for sepsis.
Chronic illnesses that have a greater risk of sepsis include: (4)
- Type 2 diabetes
- Lung disease
- Kidney disease
- HIV and AIDS
