Rehydration

In those with excessive fluid losses and dehydration, more aggresive measure like intravenous fluids or oral rehydration therapy with isotonic, electrolyte solutions containing glucose or starch should be given. Oral rehydration therapy is less expensive, often just as effective, and more practical than intravenous luids. A number of oral rehydration solutions are available, including pedialyte, rehaldehyte, ricelyte, resol. The world health organization (WHO) formula and home made Oral Rehydration Solution (ORS) are equally effective. Fluids should be givenat rates of 50 to 200 ml/kg/24 hour, depending on the hydration status. Intravenous fluid (RL solution) are prefferd acutely for patient with severe dehydration and in those who cannottolerate oral fluids.
Rice water
Rice-flour based ORS was found to be an inexpensive, palatable, easily available, and an effective alternative to glucose-based formula. Results of the study showed that rice-ORS treated episodes of watery diarrhea ended with shorten duration (median duration 2 days vs 4 days) and fever hospitalization (0,1 % vs 0,5%) compared to those treated with glucose-ORS. These differences were statically significant.

Dietary modification using kaind of healthy food
Total stopping of food is unnecessary and not recommended.

Patient should be encouraged to take frequent feedings, soft, easily digested foods such as bananas, rice, crackers, and soups are generally well tolerated and provided needed nutrients for the repair of the intestinal tract. Diary products should be avoided because transient lactase deficiency can be caused by enteric viral and bacterial infections. Caffeinated beverages and alcohol, which can enhance intestinal motility and secretions, should be avoided. It is best to avoid sugary fluids such as soft drinks. High sugar beverages tend to draw fluid into the intestinal tract rather than increase the absorption of fluid.
