Manuel,
I had bowel obstructions about every 4-6 weeks for a year. They all resolved on their own with a liquid diet, stretching, hot baths, etc. Know the symptoms of a bowel obstruction well. Unfortunately, the final one I had landed me in the ER, but the emergency team could't find the obstruction on the imaging so they waited to perform surgery. When my body went into shock after 17 or so hours they decided to take me into surgery. 90% of the small bowel died because the blood supply had been cut off the entire time and was removed leaving me with short bowel syndrome, very tiny intestine, and a new way of living.
I'm in no way discouraging you from your adventure, but it's a good consideration to have and be as prepared for as you can be, just in case.
