What do soldiers do when they have diarrhea?

Digestive Relief on the Frontlines

When military personnel face gastrointestinal issues during operations, maintaining physical readiness becomes a top priority. Simple dietary adjustments are often the first line of defense against dehydration and exhaustion.

For immediate relief, soldiers often rely on the principles of the classic BRAT diet (Bananas, Rice, Applesauce, Toast). Consuming apples and applesauce is particularly effective because they contain high amounts of pectin, a natural soluble fiber that helps solidify loose stools. In contrast, apple juice is avoided because its high sugar content can actually worsen symptoms.

Bland carbohydrates are essential for providing gentle energy without irritating the stomach lining. Plain toast without butter—though a small amount of jelly or jam is acceptable—offers easily digestible calories. Similarly, saltines and plain crackers play a crucial role in recovery. Beyond being gentle on the digestive system, their high salt content helps replenish vital sodium and electrolytes lost during illness, helping service members stay hydrated and focused.
