Enterocolitis is a condition that involves the simultaneous inflammation of the small intestine and the colon. It can be caused by viral, bacterial or parasitic infections, but also by non-infectious factors, such as inflammatory bowel disease or reactions to certain medications.
Symptoms of Enterocolitis
The symptoms of enterocolitis vary depending on the severity of the condition and its underlying cause. Among the most common symptoms are:
Abdominal pain - usually in the lower abdomen, but can be felt on the entire abdominal surface.
Diarrhea - frequent and often watery, sometimes with blood or mucus in severe cases.
Nausea and vomiting - especially in severe cases or in the case of a bacterial infection.
Fever – usually associated with bacterial or viral infections.
Bloating and flatulence - caused by inflammation of the intestines.
Dehydration - as a result of significant fluid losses through diarrhea and vomiting.
General ill-feeling - weakness, fatigue, and sometimes dizziness.
Cause
Enterocolitis can be caused by bacterial (E. coli, Salmonella, C. difficile), viral (rotavirus, norovirus) or parasitic (Giardia) infections, but also by non-infectious factors such as inflammatory bowel disease, drug reactions or intestinal ischemia.
Treatment
Treatment consists of hydration, probiotics and medication to control symptoms. In case of serious bacterial infections, antibiotics are administered, and in the case of chronic inflammations, corticosteroids or immunosuppressants can be used.
What is Enterocolitis?
Enterocolitis is a combined inflammation of the small intestine (enteritis) and the colon (colitis), which affects the normal functioning of the digestive tract. It can be triggered by a variety of causes, including bacterial, viral, parasitic infections or non-infectious factors, such as inflammatory bowel disease. Symptoms include diarrhea, abdominal pain, fever and dehydration.
Are there differences between gastroenteritis, enteritis and enterocolitis?
Yes, there are differences. Gastroenteritis affects both the stomach and the small intestine, being mainly an inflammation of the upper and lower gastrointestinal tract. Enteritis refers exclusively to the inflammation of the small intestine, without affecting the colon, while enterocolitis involves the inflammation of both, the small intestine and the colon.
Types of enterocolitis
There are several types of enterocolitis, classified according to the triggering cause. The most common are infectious enterocolitis and non-infectious enterocolitis, each having different mechanisms and requiring specific treatments.
Infectious enterocolitis
Infectious enterocolitis is caused by pathogenic microorganisms, such as bacteria (E. coli, Salmonella, Shigella), viruses (rotavirus, norovirus) or parasites (Giardia). This form of enterocolitis is often associated with contaminated food or water and is manifested by acute symptoms, such as severe diarrhea, fever and abdominal pain. The treatment is based on rehydration, diet, probiotics and in some cases, the administration of antibiotics.
Non-infectious enterocolitis
Non-infectious enterocolitis is triggered by non-microbial factors, such as inflammatory bowel diseases (Crohn's disease, ulcerative colitis), intestinal ischemia or adverse reactions to certain drugs. This form can be chronic and requires long-term treatments, including anti-inflammatory, immunosuppressive and, sometimes, surgical interventions.
What are the causes of infectious enterocolitis?
Infectious enterocolitis is triggered by a variety of pathogens, including viruses, bacteria and parasites, which invade the digestive tract, causing inflammation of the small intestine and colon. These infections are usually transmitted through the consumption of contaminated food or water, poor hygiene or contact with infected people.
Viral infections: Norovirus, rotavirus, adenovirus, astrovirus and other viral agents.
Viral infections are one of the most common causes of enterocolitis, especially in children. Norovirus is the main causative agent of acute gastroenteritis, causing severe diarrhea and vomiting. Rotavirus is particularly common in young children, causing severe diarrhea and dehydration. Other viruses, such as adenovirus, astrovirus and other viral agents, can also cause similar symptoms, lasting several days.
Bacterial infections: Salmonella, Clostridium difficile, Escherichia coli, Shigella spp., Yersinia enterocolitica.
Bacterial infections can cause more severe forms of enterocolitis. Salmonella is frequently associated with food poisoning, while Clostridium difficile is an opportunistic bacterium that can trigger enterocolitis after antibiotic treatments. Escherichia coli (especially the toxic strains) and Shigella spp. cause dysentery, characterized by bloody diarrhea. Yersinia enterocolitica mainly affects children and can mimic the symptoms of appendicitis.
Parasitic infections: Giardia lamblia, Cryptosporidium, Cyclospora.
Parasites such as Giardia lamblia, Cryptosporidium and Cyclospora can cause enterocolitis, especially in areas with poor sanitary conditions. Giardia lamblia is an intestinal parasite that causes prolonged diarrhea, flatulence and abdominal cramps. Cryptosporidium and Cyclospora are usually transmitted through contaminated water, causing severe watery diarrhea and sometimes dehydration.
What are the causes of non-infectious enteritis?
Non-infectious enteritis is caused by non-microbial factors that cause inflammation of the small intestine, such as inflammatory bowel diseases, the use of certain drugs or chronic digestive syndromes. These causes can lead to persistent symptoms, including abdominal pain, diarrhea and digestive discomfort.
Inflammatory causes
Inflammatory causes of non-infectious enteritis include chronic conditions such as Crohn's disease, ulcerative colitis and irritable bowel syndrome, which cause inflammation and dysfunction in the digestive tract, manifested by diarrhea, abdominal pain and gastrointestinal discomfort.
Crohn's disease
Crohn's disease is a chronic inflammatory condition that can affect any part of the digestive tract, but most commonly attacks the small intestine. Deep inflammation can cause diarrhea, abdominal pain, weight loss and, in severe cases, the formation of fistulas or abscesses.

Ulcerative colitis
Ulcerative colitis is another intestinal inflammatory disease that mainly affects the colon, but can also cause enteritis in some cases. It is characterized by inflammation and ulceration of the intestinal mucosa, causing bloody diarrhea, abdominal cramps and fatigue.
Irritable bowel syndrome
Irritable bowel syndrome (IBS) is not an inflammatory disease itself, but it can trigger symptoms similar to enteritis, such as diarrhea, constipation, bloating and abdominal pain. Although the exact cause is unknown, IBS is often linked to stress and food sensitivities.
Medicinal causes
Certain medications can cause enteritis as a side effect. Prolonged use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can irritate the intestinal lining and cause inflammation. Also, chemotherapy, antibiotics or immunosuppressive drugs can disturb the bacterial balance in the intestine, leading to inflammation and unpleasant digestive symptoms.
Risk factors for enterocolitis
Enterocolitis can affect people of all ages, but certain risk factors can increase the likelihood of developing this condition, either due to increased exposure to pathogens or due to the vulnerability of the immune system.
Social and life factors
Factors such as traveling to areas with poor hygiene, consuming contaminated food or water, close contact with infected people or living in crowded environments increase the risk of contracting enterocolitis. Also, the lifestyle that involves an unhealthy diet and chronic stress can aggravate the symptoms.
Compromised immunity
People with a weakened immune system, such as those undergoing chemotherapy treatments, suffering from HIV/AIDS or taking immunosuppressive drugs, are more prone to intestinal infections, including enterocolitis, because their bodies cannot effectively fight pathogens.
Poor hygiene conditions
Lack of access to clean drinking water, poor personal hygiene or improper handling of food are important factors that increase the risk of enterocolitis, especially in underdeveloped areas or in communities with insufficient sanitary conditions.
Symptoms of Enterocolitis
The symptoms of enterocolitis can vary depending on the cause, the severity of the condition and the affected area of the digestive tract. In general, enterocolitis is manifested by a combination of gastrointestinal symptoms, but certain characteristics are specific to each cause.
Common symptoms
Common symptoms of enterocolitis include:
- Diarrhea (watery, bloody or mucus)
- Abdominal pain and cramps
- Nausea and vomiting
- Fever
- Dehydration
- Bloating and flatulence
- General state of ill health and fatigue
Specific symptoms depending on the cause
The symptoms of enterocolitis vary depending on the cause that triggers it, each type of infection (viral, bacterial or parasitic) having specific characteristics that can help identify the pathogen and establish the appropriate treatment.
Symptoms of viral enterocolitis
Viral enterocolitis causes frequent watery diarrhea, nausea, vomiting and mild fever. Symptoms are often self-limiting, lasting between 1 and 3 days, but in severe cases (such as rotavirus infection), dehydration and the need for intensive rehydration may occur.
Symptoms of bacterial enterocolitis
Bacterial enterocolitis is often characterized by severe diarrhea, often with blood or mucus, high fever, and intense abdominal cramps. Bacteria such as Shigella, Salmonella or E. coli can cause these symptoms, and in serious cases can lead to complications such as septicemia.
Symptoms of parasitic enterocolitis
Enterocolitis caused by parasites, such as Giardia or Cryptosporidium, is manifested by persistent diarrhea, which can last several weeks, accompanied by bloating, flatulence and abdominal cramps. In some cases, symptoms of malabsorption may also appear, leading to weight loss and weakness.
Diagnosis of enterocolitis
The diagnosis of enterocolitis involves a combination of symptom evaluations and diagnostic tests to determine the cause and severity of the condition. A correct diagnosis is essential to guide the appropriate treatment and prevent complications.
Symptomatic evaluation
Symptomatic assessment consists of discussing with the patient the medical history, duration and nature of symptoms, as well as risk factors and recent exposures (such as travel or consumption of suspect foods). The doctor will analyze common symptoms, such as diarrhea, abdominal pain and fever, and ask about possible specific symptoms depending on the suspected cause.
Diagnostic tests
Diagnostic tests may include blood tests to assess general health and signs of infection, stool tests to identify pathogens (bacteria, viruses or parasites) and, in some cases, imaging (ultrasonography, CT) to rule out complications. These tests help confirm the diagnosis and determine the best treatment method.

Treatment of enterocolitis
The treatment of enterocolitis depends on the specific cause and the severity of the condition, being composed of several approaches that include supporting the body, drugs and complementary therapies.
Supportive treatment
Supportive treatment is essential to prevent dehydration and maintain electrolyte balance. It involves rehydration through the consumption of clear liquids, oral rehydration solutions or, in severe cases, the administration of intravenous fluids. Also, patients are advised to follow a light diet, avoiding irritating or hard-to-digest foods.
Drug treatment
Drug treatment is specific for the cause of enterocolitis. Antibiotics may be necessary in severe bacterial infections, while antiviral drugs may be used in viral cases. In addition, antidiarrheal drugs can be prescribed, but with caution, because they can aggravate bacterial infections. In the case of inflammatory bowel diseases, corticosteroids or immunosuppressants can be used to reduce the inflammation.
Integrative therapy
Integrative therapy includes complementary methods that can support conventional treatment. These may include the use of probiotics to restore gut flora, personalized nutritional therapies, acupuncture or stress management techniques such as meditation and yoga. These approaches can help relieve symptoms and improve the quality of life of patients.

Diet in case of enterocolitis
Diet plays a crucial role in the management of enterocolitis, helping to reduce inflammation and restore intestinal health. In the first days after the onset of symptoms, a light diet is recommended, which includes easily digestible foods, such as boiled rice, bananas, applesauce and toast. It is important to avoid fatty, spicy or acidic foods, as well as dairy products, which can irritate the intestinal mucosa. As symptoms improve, foods rich in nutrients and probiotics, such as yogurt, cooked vegetables and clear soups, can be gradually introduced. Adequate hydration is essential, through the consumption of liquids and rehydration solutions, to prevent dehydration.
Conclusion
Enterocolitis is a gastro-intestinal condition that can be caused by infectious or non-infectious factors, having a significant impact on the patient's quality of life. Correct diagnosis and treatment are essential to manage symptoms and prevent complications. Diet plays an important role in the recovery process, and the therapeutic approach must be personalized according to the cause and severity of enterocolitis. Through a combination of supportive treatment, medication and a proper diet, most patients can return to normal health.
