Quick Answer
If diarrhea occurs in the backcountry, immediately identify the cause, rest, and drink plenty of fluids to replace lost electrolytes. Use oral rehydration solutions or electrolyte tablets to replenish essential minerals. Seek medical attention if symptoms persist or worsen.
Assessing the Situation
When diarrhea strikes in the backcountry, your primary concern is hydration and electrolyte balance. If you’re with a partner or group, have one person stay with the afflicted individual while the others seek help or assess the situation. If you’re solo, prioritize your own safety and seek aid as soon as possible.
Rehydration and Electrolyte Replacement
Drink at least 1-2 quarts (1-2 liters) of water or an oral rehydration solution within the first hour to replace lost fluids. Use electrolyte tablets or powders to replenish crucial minerals, aiming for a balance of sodium, potassium, and chloride. Aim to consume 5-10 grams of carbohydrates per hour to maintain energy levels.
Medical Evaluation and Evacuation
If symptoms persist or worsen, seek medical attention as soon as possible. Monitor vital signs, such as body temperature and blood pressure, for signs of dehydration or other complications. If you’re unable to walk or move, consider signaling for help or using a satellite phone to call for rescue.
