This test is similar to sigmoidoscopy, but the physician looks at the entire colon. In most cases, replacing lost fluid to prevent dehydration is the only treatment necessary. These medicines sometimes trap the organism in the intestines, prolonging the problem. In these situations, physicians usually prescribe antibiotics. Physicians treat viral causes with medication or leave them to run their course, depending on the severity and type of the virus.
Dehydration is particularly dangerous for children, who can die from it within a matter of days.
Although water is extremely important in preventing dehydration, it does not contain electrolytes. To maintain electrolyte levels, you should also have chicken or beef broth, which contains sodium, and fruit and cola drinks, which contain potassium. For children, physicians often recommend a special rehydration solution with essential nutrients. You can buy this solution in the grocery store without a prescription. Examples include Pedialyte, Ceralyte, and Infalyte.
