What treatment is recommended for a normotensive patient with gastroenteritis and hematochezia?

In cases of gastroenteritis, the primary concern is typically fluid loss due to diarrhea and potential vomiting, which can lead to dehydration. For a normotensive patient experiencing gastroenteritis, oral rehydration therapy is specifically recommended because it is effective for replacing lost fluids and electrolytes without the need for intravenous interventions, which are generally reserved for more severe cases involving dehydration or when oral intake is not feasible.

Oral rehydration therapy is effective as it typically consists of a balanced mixture of water, salts, and sugar that helps to replenish electrolyte stores while promoting hydration through oral intake. This method is not only less invasive but also more convenient for patients who are able to tolerate oral fluids.

In contrast, intravenous fluids would be more appropriate if the patient were showing signs of dehydration or if oral rehydration failed. Close observation may be warranted in certain situations, but monitoring alone does not address the immediate need for fluid replacement. Antidiarrheal medications can sometimes be inappropriate in the setting of infectious gastroenteritis, as they may prolong the illness by slowing down the clearance of the pathogen from the intestines.

Thus, oral rehydration therapy is the most appropriate initial treatment for a normotensive patient with gastroenteritis who is
