In patients with acute diarrhea, stool cultures should be reserved for grossly bloody stool, severe dehydration, signs of inflammatory disease, symptoms lasting more than three to seven days, immunosuppression, and suspected nosocomial infections.

    How Can Dehydration From Diarrhea Be Prevented And Treated

    Oral rehydration solutions are liquids that contain a carbohydrate and electrolyte . Originally, the World Health Organization developed the WHO-ORS to rapidly rehydrate victims of the severe diarrheal illness, cholera. The WHO-ORS solution contains glucose and electrolytes. The glucose in the solution is important because it forces the small intestine to quickly absorb the fluid and the electrolytes. The purpose of the electrolytes in the solution is the prevention and treatment of electrolyte deficiencies.

    In the U.S., convenient, premixed commercial ORS products that are similar to the WHO-ORS are available for rehydration and prevention of dehydration. Examples of these products are Pedialyte, Rehydralyte, Infalyte, and Resol.

    Most of the commercially available ORS products in the U.S. contain glucose. Infalyte is the only one that contains rice carbohydrate instead of glucose. Most doctors believe that there are no important differences in effectiveness between glucose and rice carbohydrate.

    Whats The Difference Between Normal Diarrhea And Severe Diarrhea

    There are actually several different ways to classify diarrhea. These types of diarrhea include:

    • Acute diarrhea: The most common, acute diarrhea is loose watery diarrhea that lasts one to two days. This type doesnt need treatment and it usually goes away after a few days.
    • Persistent diarrhea: This type of diarrhea generally persists for several weeks two to four weeks
    • Chronic diarrhea: Diarrhea that lasts for more than four weeks or comes and goes regularly over a long period of time is called chronic diarrhea.
