Quite commonly, due to the barrage of newness the body experiences on an outdoor outing (new sensations, new exercise habits, new diet, etc) the body can stop the system up while it tries to figure out what is going on. We regularly warn participants that this is an expected and natural response, and some departure from "normal" habits is to be expected.

However, at a certain point, chronic constipation can lead to greater complications (fecal impaction, gross discomfort, diminishing quality of experience).

Is there an excepted standard on how long is "too long" to be stopped up before we should start aggressively treating or considering evacuation (of the person if not the bowels)?

  • If you're in a "pack it out" area for a day or two, a little constipation might be a lucky break! :-) More seriously, severe intestinal cramps can occur at altitude with not too much constipation. Gas needs to get out one way or the other.

    This really is more of a general healthcare problem - although it is useful for the outdoors. I have been able to go for about 4 days out in the wild before needed to clear out, without too much discomfort - but I don't recommend this as a regular thing, or have any idea how long would be 'too long'.

After leading a number of trips in the backcountry I've had some experience with greenhorns experiencing this unfortunate reality.

Everyone's Body is different

Some people will need pass a BM every morning, for others every other day is normal. As a trip leader with young kids I make sure to monitor and ask about results from each of the participants. It's my position that if the subject is taboo, then those who already are having a problem will be even more embarrassed.

Using the other members of the group to help monitor if someone has gone days, or is uncomfortable can at times be a good resource as well. You don't need to ask them to spy, usually making a general conversation about the subject is enough to elicit a response.

Where to draw the line

I will allow participants to go a couple days without a productive BM, but on the third day I start becoming more concerned. This is usually the point that I take action by speaking to the person directly.

If the problem is not one of motivation (ie. participant wants to go but cannot) then generally the problem is dehydration. Proper hydration throughout the day, until urine runs clear usually solves the problem.

If not and problems persist for 4-5 days:

  • Laxatives can be provided.
  • Stool softeners can be provided
  • Ultimately, the participant may need to be brought to the doctor to treat impaction.

Motivational Issues

If the problem is not with dehydration or diet, then it likely rests with the participant not wanting to feel exposed, or not feeling comfortable with the surroundings.

These can sometimes be the hardest to deal with, and will require one-on-one discussion with the participant about their concerns, fears, and ultimately how to resolve the problem.

Don't start off with the scared strait approach. If you start right into the..."here are all the things that could happen if you don't poop!" speech, you are likely to make them more anxious and more likely to get bottled up.

Best of luck out there!


As a scout leader I have been taking many groups of young people for hikes lasting from one night to more than one week. I have often experienced that participants refrain from pooping outside and that this is leading to painful constipation after typically three to four days. When deviation from own (often daily) routines, the risk of getting into constipation rises from day 1.

In our group we always bring up the toilet issue when planning for a hike. We try to normalize it, e.g. by speaking explicit about how to do it and stressing the fact that we all do it. Thus we have found it wise to be open about our own needs as leaders, and that even the adults have no other choice than pulling shorts down and squat with a bare bum. And reminding that we all like to have some privacy in just that moment.
