Gastrointestinal (GI) sepsis, or gut-origin sepsis, is a severe condition where an infection or injury in the digestive tract triggers the body's immune response, leading to systemic inflammation that damages organs, potentially causing organ failure and death, often starting with gut issues like leaks, infections, or ischemia. It's a medical emergency where the gut's compromised barrier allows bacteria or toxins to enter the bloodstream, intensifying the body's dysregulated response and leading to multi-organ dysfunction.
A gastrointestinal tract infection refers to inflammation in the digestive system caused by bacterial, viral, or parasitic pathogens. Common gastrointestinal tract infection causes include: Consuming undercooked or contaminated food, such as raw meat and eggs. Drinking untreated or contaminated water.
Sepsis symptoms can vary depending on the stage of the condition and the underlying cause, but common signs include:
Early warning signs of sepsis include fever or low temperature, chills, rapid breathing or heart rate, confusion, slurred speech, extreme pain or discomfort, clammy/sweaty skin, and reduced urine output, with children potentially showing fewer wet nappies, vomiting, or a non-fading rash. These symptoms, often appearing after an infection, signal a severe body response and require immediate emergency care, as sepsis can rapidly worsen, according to the Mayo Clinic.
These infections are most often linked to sepsis:
You get sepsis when your body has an extreme, damaging reaction to an infection (bacterial, viral, fungal, or parasitic), causing its own immune response to harm tissues and organs, leading to potential organ failure; it starts with any infection, like pneumonia, UTI, or a skin wound, and becomes a medical emergency when the body's defense system overreacts.
Those that more commonly cause sepsis include infections of:
Red flag sepsis symptoms in adults and older children
Slurred speech, confusion, or disorientation. Extreme shivering or muscle pain. Significantly reduced urine output (passing no urine in a day) Severe breathlessness or rapid breathing.
As severe sepsis usually involves infection of the bloodstream, the heart is one of the first affected organs.
At a glance. Sepsis is a fast-moving, life-threatening emergency caused by an extreme immune response to infection. Use TIME: Temperature, Infection, Mental decline, Extremely ill — to recognize sepsis symptoms early. Prevent sepsis by treating infections early, practicing hygiene and staying current on vaccinations.
It is well-established that sepsis results in a dysfunction of the intestinal barrier with increased permeability (5, 9, 10, 23, 48, 49, 51, 68, 69).
The evidence behind the “golden hour” protocol
The main finding was that patients who received antibiotics within the first hour of sepsis recognition had a 79.9% chance of survival. It was also found that with every additional hour, the chance of survival decreased by 7.6%.
Sepsis can initially look like flu, gastroenteritis or a chest infection. There is no one sign, and symptoms present differently between adults and children. Other symptoms include: Slurred speech or confusion.
Bowel infections are caused by germs in the gut and are sometimes called gastrointestinal infections or gastroenteritis. You can get a bowel infection by consuming contaminated water or food or by having contact with another person who has the infection.
Recent molecular studies have also indicated that pathogenic bacteria can invade and colonize the gut before sepsis onset, thus potentially causing sepsis through bacterial translocation. Further research is required to explore the conditions of bacterial translocation and the associated biomarkers.
Self care
Sepsis can be triggered by an infection in any part of the body. The most common sites of infection that lead to sepsis are the: lungs. urinary tract.
The six main symptoms of sepsis are: Shortness of breath. Fever, chills, shivering, or feeling very cold. High heart rate or low blood pressure.
Many sepsis survivors have said that when they were ill, it was the worst they ever felt. It was the worst sore throat, worst abdominal pain, or they felt that they were going to die. Children developing sepsis may exhibit different symptoms, as seen below.
blue, grey, pale or blotchy skin, lips or tongue – on brown or black skin, this may be easier to see on the palms of the hands or soles of the feet. a rash that does not fade when you roll a glass over it, the same as meningitis. difficulty breathing, breathlessness or breathing very fast.
The Sepsis Six consists of three diagnostic and three therapeutic steps – all to be delivered within one hour of the initial diagnosis of sepsis: Titrate oxygen to a saturation target of 94% Take blood cultures and consider source control. Administer empiric intravenous antibiotics.
However, over the past 25 y it has been shown that gram-positive bacteria are the most common cause of sepsis. Some of the most frequently isolated bacteria in sepsis are Staphylococcus aureus (S. aureus), Streptococcus pyogenes (S. pyogenes), Klebsiella spp., Escherichia coli (E.
Anyone with an infection can get sepsis. Some people are more likely to get an infection that could lead to sepsis, including: babies under 1, particularly if they're born early (premature) or their mother had an infection while pregnant. people over 75.
Almost any virus can cause viral sepsis in susceptible populations (24). Herpes simplex virus (HSV) and enteroviruses are the most common viral causes of neonatal sepsis (32), while enteroviruses and human parechoviruses (HPeVs) are the most common causes of viral sepsis in young children (33).
Causes. The symptoms of sepsis are not caused by the germs themselves, but rather the response of the body to the germs. A bacterial infection anywhere in the body may set off the response that leads to sepsis. The most common infections include those of the lung, urinary tract, gut or skin.
