Why am I so gassy?
Last updated September 3, 2026.
Passing gas 13-21 times daily is normal. More than that usually means swallowed air or fermentable carbs - lactose, beans, sugar alcohols in sugar-free products. Gas with diarrhea, blood, or weight loss needs a doctor.
What to do
- Run a two-week food diary - personal triggers vary.
- Try one week lactose-free - the most common single cause.
- Check sugar-free gum and mints - sorbitol and xylitol ferment hard.
- See a doctor for the flags - diarrhea, blood, weight loss, night pain.
