Our seven-year-old son vomited several times during one night at the beginning of the year. He vomited twice again the next morning. He had never experienced such severe nausea before. He spent most of the day in bed and slept a lot. Over the next four days, he usually felt quite well in the mornings, but always felt nauseous in the evenings, without vomiting again. By the fifth day, he had fallen asleep very early again in the evening, so I had prepared an emergency bowl for him once more. An hour later, I checked on him and could smell that he had probably vomited again. Sure enough, the bowl was full—he had probably woken up briefly, vomited, mostly hitting the bowl, and then gone right back to sleep.

What happened:
Two weeks before the symptoms began, we went on vacation. Completely unexpectedly, a good friend of our other son was at the same vacation spot, so they played together almost the entire time. His brother was excluded most of the time and was rarely able to play with them, which annoyed him greatly and which he probably experienced as a territorial conflict involving the ectodermal lesser curvature of the stomach: The siblings would normally have done a lot together on vacation, which he had certainly been looking forward to, but as it was, his brother was hardly available to play with him.

There were no symptoms during the active conflict phase. When the vacation ended after 8 days, it took us a few days to get back into our daily routine. On the fourth day at home, the children played together extensively and happily in the evening, which was probably the moment of conflict resolution and the beginning of the conflict-resolved phase of SBS. The mucous membrane became inflamed as part of the cell growth process, causing severe nausea upon contact with stomach acid the following night. In the middle of the conflict-resolved phase, around five days later, the epileptoid crisis occurred in the middle of sleep, during which the mucous membrane suddenly became highly hypersensitive (as it belongs to the inner skin system) Once again, the sudden vomiting typical of the epileptic crisis of this SBS occurred. The symptoms then improved significantly and disappeared completely after a few more days when the SBS had run its course.
