Diarrhea and Gastroenteritis
- Diarrhea is defined as an increase in stool fluidity, volume, and frequency.
- Acute diarrhea lasts less than two weeks.
- Chronic diarrhea lasts more than two weeks.
- Important factors about formula feeding include needing a number of bottles each day, how to clean them, and how much milk or water is needed, and how to prepare it.
- Babies need a certain amount of calories per kg (e.g., 80-120 Kcal/kg/day).
- Feeding babies every 2-3 hours is typical for infants and young children.
- A baby is typically considered well-fed if it is comfortable after a feeding and does not cry; it should sleep for around 2 hours after feeding.
Causes of Seizure in Patients with Diarrhea
- Dehydration
- Fever (Febrile Seizures)
- Electrolyte imbalances (hyper/hypo natremia)
- Hemolytic Uremic Syndrome (can lead to uremic encephalopathy or hypertensive encephalopathy).
- Parental diarrhea (can be a symptom of meningitis but not always).
- Systemic (non-GIT) conditions and infections can also cause diarrhea.
Mechanisms of Diarrhea
- Osmotic (due to digestive enzyme deficiencies or ingestion of unabsorbable solutes with common examples include viral infections, lactase deficiency, or infections).
- Secretory (increased secretion and decreased absorption common in cholera, and toxigenic E. coli).
- Exudative (inflammation- decreased colonic reabsorption and increased motility common in bacterial enteritis).
- Increased motility (decreased transit time common in Irritable bowel syndrome).
Causes of Acute Diarrhea in Infancy and Childhood
- Non-enteric causes: otitis media, meningitis, sepsis, and parental diarrhea.
- Non-infectious causes: food allergies, drug side effects, malabsorption.
- Infections of the gastrointestinal tract (e.g., rotavirus).
Infantile Gastroenteritis: Principal Causes
- Escherichia coli (EPEC, ETEC, EIEC).
- Viruses (rotavirus, noroviruses).
Enteropathogenic E. coli (EPEC)
- Affects the small intestine.
- Causes local destruction of intestinal epithelial cells.
- Causes infantile diarrhea and does not involve bloody stools.
- Often accompanied by fever, nausea, and vomiting.
- Self-limiting, no specific antibiotic treatment necessary.
- Over 20 identified serotypes in outbreaks.
- May affect maternity or neonatal units.
Enterotoxigenic E. coli (ETEC)
- Affects the small intestine.
- Causes low-grade fever, nausea, watery diarrhea, and cramps.
- Produces heat-labile enterotoxin and heat-stable factors that have cholera-like effects.
- Leads to fluid and electrolyte loss.
Enteroinvasive E. coli (EIEC)
- Affects the large intestine, causing bloody diarrhea.
- Develops into bacillary dysentery.
- Causes invasion and local destruction of intestinal epithelial cells.
- Not associated with enterotoxins.
Viral Gastroenteritis
- Frequent cause of infantile gastroenteritis.
- Up to 50% of cases caused by rotavirus (most common).
- Short incubation period (2-4 days).
- Often presents as diarrhea of mild to moderate severity, potentially with vomiting.
- More common in winter months.
- Diagnosed by detection of rotavirus antigen in stool.
- Treatment is supportive care.
Other Viruses Causing Infantile Gastroenteritis
- Noroviruses and sapoviruses (family Caliciviridae).
- Astroviruses.
- Adenoviruses.
Management of Infantile Gastroenteritis
- Replacement of fluid and electrolytes.
- Antibiotics are typically not indicated.
- Breastfeeding should be continued.
Other Infectious Causes of Infantile Gastroenteritis
- Salmonella
- Shigella (bacillary dysentery)
- Campylobacter jejuni.
- Giardia lamblia.
Enterohaemorrhagic E. coli (EHEC)
- Causes hemorrhagic colitis with abdominal cramps.
- Bloody diarrhea.
- Can cause hemolytic uremic syndrome (HUS).
- Often caused by E. coli O157:H7.
- Children are at greater risk than adults for complications.
- Antibiotics are not recommended as they can increase the risk of HUS.
Haemolytic Uraemic Syndrome (HUS)
- May follow uncomplicated diarrheal illness, with common symptoms like anemia, acute renal failure and thrombocytopenia.
- Caused by verocytotoxin (VTEC).
- Diagnosed by lab tests like sorbitol non-fermenting strains.
Cryptosporidiosis
- Self-limiting diarrheal illness in children, often accompanied by nausea and vomiting.
- Acquired by drinking or consuming contaminated water with cysts of Crypto parvum.
- Extremely resistant to chlorination.
- Usually caused by infected cattle.
- More severe manifestations in immunocompromised persons (e.g. AIDS).
Gastroenteritis Associated with Travel
- Enterotoxigenic E. coli (Traveller’s diarrhea).
- Salmonella and Campylobacter spp (food poisoning).
- Shigella spp (bacillary dysentery).
- Giardia lamblia (giardiasis).
Giardiasis
- Caused by Giardia lamblia (protozoan pathogen).
- Cosmopolitan, affects globally.
- Acquired by ingestion of contaminated food or water; cysts resist chlorination.
- Develops into trophozoites in the duodenum.
- Symptoms include cramping, flatulence, diarrhea, and steatorrhea.
Giardiasis: Diagnosis and Management
- Identification of cysts in stool (acid-fast stain or PCR).
- May need duodenal aspirate or small bowel biopsy for diagnosis in certain cases.
- Treatment is typically with metronidazole.
Bacillary Dysentery (Shigellosis)
- Caused by Shigella sonnei (most prevalent in developed countries).
- Often presents as a mild, self-limiting illness.
- Low infecting dose and is typically acquired via direct contact.
- Locally invasive in the large bowel
- Isolated on selective media
- Other Shigella species (e.g. flexneri, boydii, dysenteriae) typically acquired abroad and can lead to severe illness in developing countries
Uncommon Causes of Diarrhea
- Amoebic dysentery (causative organism: Entamoeba histolytica, often associated with eating contaminated food containing cysts and can cause colon ulceration. Variations in symptoms exist from mild cases to severe cases with blood and mucus in stool. Other severe symptom is liver involvement that can cause hepatitis and liver abscess).
- Amoebic dysentery can have severe complications such as perforation of the large bowel and peritonitis.
- Symptoms may also involve the liver.
Cholera
- Severe diarrheal illness.
- Rice water stools.
- Vomiting and nausea may accompany the disease.
- Leads to dehydration, prostration, and electrolyte loss.
- Caused by toxigenic Vibrio cholerae (3 types e.g. classic, El Tor, and O139).
- Usually transmitted through water.
Other Infections of the Intestinal Tract
- Enteric fever (typhoid and paratyphoid) caused by Salmonella enterica.
- Yersinia enterocolitica gastroenteritis.
- Aeromonas hydrophila (aquatic organism).
- Plesiomonas shigelloides colitis
- Pseudomembranous colitis (C. difficile).
Complications of Diarrhea
- Dehydration.
- Metabolic acidosis.
- Gastrointestinal Complications (e.g., perforation, and secondary lactase deficiency).
- Nutritional complications.
Management of Diarrhea
- Oral Rehydration Solutions (ORS).
- Effective for all types and degrees of dehydration.
- Prevention is important via good sanitation and hygiene.
Oral Rehydration Solution (ORS) Composition
- Glucose.
- Sodium Chloride.
- Tri-Sodium Citrate (bicarbonate).
- Potassium Chloride
Chronic Diarrhea (> 2 Weeks)
- The diagnosis should be made for children who are growing well and who do not have fluid or electrolyte abnormalities or fail-to-thrive issues.
- Focus on identifying if the cause is due to infectious etiology, or a secondary lactase deficiency).
- Investigations can include stool, urinalysis, blood count, and electrolytes.
- If FTT exists more investigation (e.g: nutritional status, antibody, genetic and other tests) may be needed.
Toddler's Diarrhea
- Most common cause of chronic diarrhea during infancy.
- Diagnosis is usually made by excluding other conditions (no weight loss, no fluid or electrolyte abnormalities, and no FTT).
- Onset is typically between 6 and 36 months.
- Usually ceases spontaneously between 2-4 years.
- History of excessive fruit juice intake may cause disaccharide malabsorption.
Lactase Deficiency (Lactose Intolerance)
- Clinical features include chronic watery diarrhea, abdominal pain, bloating, and borborygmus.
- Diagnosis is made by trying off milk/ lactose free milk or performing a breath hydrogen test in patients over 6 years of age.
- Management includes following a lactose-free diet.
Celiac Disease
- Also known as gluten-sensitive enteropathy.
- Mucosal defect associated with toxic or immunologic reaction to gluten found in foods such as barley, rye, oats and wheat.

- May have a high prevalence in children with atopic conditions such as eczema, asthma, allergic rhinitis and food allergies.
- Two clinical scenarios exist, enterocolitis, and enteropathy.
- Enterocolitis is characterized by acute symptoms (vomiting, diarrhea, anemia, and hematochezia).
- Enteropathy is characterized by chronic symptoms (chronic diarrhea, hypoalbuminemia and associated treatments include starting with a casein hydrolysate formula).
