How effective is fluid replacement for treating dysentery?

Dysentery: Dysentery is usually treated with oral hydration. For severe dehydration, intravenous fluids may be required. Most start with a clear diet and then workup to a BRAT diet. Medications may be used for nausea & vomiting. Sometimes diarrhea medications like loperamind or Lomotil might be prescribed. Because dysentery could be caused by viruses, protozoa, parasites or bacteria it will be determined if antibiotics or medications to treat parasites, etc. are indicated.
