The questions you searched at 2am, answered plainly.
Each page gives the mechanism, the timings and the way to tell 1 cause from another. None of them can tell you what your trigger is, because that answer is in your own 14 days of logs. They can tell you where to look.
- 01Why am I bloated every evening?Evening bloating is rarely the evening meal. It is usually the day's fermentable food arriving in your colon 4 to 8 hours later, on top of gas that never left. The clock is the clue, and it points backwards to lunch.Updated 2026-08-23
- 02Is dairy causing my gas?It might be, and dairy is one of the easier suspects to test. Lactose gas starts 30 minutes to 2 hours after a dose, and it scales with the dose. If a glass of milk does it and hard cheese does not, that pattern is your evidence.Updated 2026-08-23
- 03How long after eating onions do symptoms start?Usually 4 to 8 hours, and sometimes up to 12. Onions are high in fructans, which your small intestine cannot absorb at all. They ferment in your colon, so lunch produces the gas you feel at 8pm.Updated 2026-08-23
- 04Bristol type 6 every morning: what does it mean?Type 6 means your stool moved through your colon too fast for water to be reabsorbed. Every morning, on a schedule, points at something repeated the day before rather than a one-off, because the morning urge itself is normal.Updated 2026-08-23
- 05I cut gluten for a week and nothing changed. What now?A week is not a failed test, it is not a test at all. You changed 1 thing you noticed and several you did not, you had no control days, and normal symptoms vary enough to swamp the difference.Updated 2026-08-23
