Bloating after every meal? Root causes and a 4-week reset
If your belly is flat in the morning and looks two months pregnant by evening, that's not "just how you're built". It's dysbiosis, low stomach acid, a sluggish liver, or a food you don't tolerate — and every one of them is fixable.

The 6 root causes
Low stomach acid (hypochlorhydria)
Common after 40, on PPIs (omeprazole) or with H. pylori. Undigested protein rots in the small bowel — hello, bloating within 20 minutes of a meal.
SIBO (small intestinal bacterial overgrowth)
Bacteria that belong in the colon migrate into the small bowel and ferment carbs early. Signature: bloating that peaks 60–90 minutes after eating, with burping or acid reflux.
Food sensitivity (not allergy)
Lactose, gluten, FODMAPs, garlic/onion for some people. Not IgE — no rash, no anaphylaxis — just gas, cramps and mood drop.
Sluggish bile flow
The liver's bile emulsifies fat. Poor bile flow = fat maldigestion = bloating, greasy or floating stools, and vitamin D/E/K absorption drops.
Chronic stress
The vagus nerve controls gut motility. A stressed nervous system slows the migrating motor complex — food sits, ferments, bloats.
Constipation (silent)
If you're not passing a full easy stool 1–2×/day, gas has nowhere to go. Magnesium bisglycinate + fibre resolves this quietly.
The 4-week reset
- Week 1 — Slow down. Eat sitting, chew each bite 20 times, no water 15 minutes before or during meals (dilutes acid).
- Week 2 — Support digestion. A tablespoon of apple cider vinegar in warm water before heavy meals, or bitter salad greens as a starter. Warm ginger tea after dinner.
- Week 3 — Fix the biome. Add fermented foods (dahi, kanji, a small amount of pickle). Start a multi-strain probiotic. Reduce ultra-processed food.
- Week 4 — Cover fat digestion. Support bile flow with cruciferous veg, beetroot, artichoke, and a liver-gut supplement stack (see below).
When bloating is a red flag
- Unintended weight loss + bloating — needs an endoscopy/colonoscopy.
- Blood in stool, black stool, or persistent iron deficiency.
- New-onset severe bloating after 50 — investigate ovarian and colon causes.
- Bloating with fever, night sweats or persistent pain.
Liver Biome+ — for the gut-liver axis behind the bloat
Bloating is often as much a liver-and-bile story as a gut story. Liver Biome+ combines liposomal silymarin and curcumin for bile flow, NAC and ALA for hepatic detox, and a multi-strain probiotic for the gut biome — the same-side-of-the-portal-vein view of digestive comfort.
