Document Summary
Gastroenteritis (gastro: gastroenteritis is inflammation of the stomach and intestines, which is typically a result of bacterial toxins or viral infections. Gastroenteritis can be acute or chronic: acute gastroenteritis is usually infectious (meaning it is transmittable). Can cause haemolytic syndrome, which is characterized by progressive renal failure. C. difficile is usually hospital acquired. Giardia also known as beaver fever. Caught through contaminated food/water (beaver feces: gastroenteritis is caused by abnormal intestinal water and electrolyte transport. The foreign toxins pull water into the intestinal tract and the water is lost through diarrhea and vomiting -> dehydration! The younger the child, the more vulnerable they are. The child has not been exposed to many pathogens and has not acquired protective antibodies. Also, newborns do not have a well-developed gi mucosal barrier. Children also have higher metabolic rates, resulting in more water lost. Secretory diarrhea vs. osmotic: gastro can be spread through: Fecal-oral route: through ingesting contaminated feces via food or water.
