Had solid bm this morning after 5 days of none. afterwards been feeling really nauseated and can't eat. hx of gastritis. no fever?

BM frequency varies: widely, commonly from several times/day to once every 3 days, less if not eating much or foods with very low residuals. You are describing symptoms, responses we may become consciously aware of, after intense enough or less distracted. However symptoms are only clues, not causes. U volunteer Hx of gastrointestinal issues. As embodied Soul↔Mind↔Brain↔Body creatures, controls/causes mostly internal.
