Bloating after meals is often treated with a generic enzyme at a single dose, and it often fails. The food that triggers the bloating points to the mechanism: protein suggests low stomach acid, fiber suggests low pancreatic enzymes, and fat suggests gallbladder sludge. The clinical strategy of Datis Kharrazian, PhD, DHSc, DC, MS, MMSc, FACN, is to match the support to the food, then raise the dose until the bloating resolves.
A patient reports bloating most evenings and has already tried probiotics and cutting out gluten. Breakfast and lunch are fine. Asked what she ate on her worst nights, she names steak or another heavy protein meal. It sits in her stomach like a brick. The pattern points to low stomach acid, and none of her earlier changes addressed it.
Why digestive support for bloating fails
There are two common mistakes. The first is not asking which food causes the bloating, so the patient gets support that doesn't match the mechanism.
The second is often overlooked: the dose is too low. A patient who takes one capsule, feels no change, and stops has not had a real trial.
What does bloating after each type of food mean?
A few questions about the meal identify the mechanism:
- Protein meals: bloating and a heavy, brick-in-the-stomach feeling after steak or other protein points to low hydrochloric acid, which the stomach needs to digest protein.
- Fiber meals: bloating and distension after a salad or other high-fiber meal points to low pancreatic enzymes.
- Fatty or fried meals: bloating after fries or other greasy food points to thickened bile or gallbladder sludge. The gallbladder can't release bile well enough to digest the fat.
How do you find the right dose of digestive enzymes?
Start with one capsule with the problem meal. If the bloating is still there, add one more capsule at the next similar meal, and keep going until the bloating and distension go away.
This applies to hydrochloric acid, pancreatic enzymes and bile support alike. It takes a few days of adjusting, and the working dose varies from patient to patient.
How do bile salts help with fat intolerance?
Bile salts can be very effective at thinning the bile so it flows and digests fat. Lipase, the enzyme that breaks down fat, can be taken alongside them.
The same titration applies: start with one capsule and increase until the bloating improves. Too much bile salt can cause diarrhea and more frequent bowel movements, which signals the dose has gone past what the patient needs.
What if everything causes bloating?
Some patients bloat no matter what they eat. Sugar, fiber and almost any food leaves them distended, and some say they look pregnant all day.
That pattern suggests small intestinal bacterial overgrowth (SIBO). Bacteria from the large intestine have moved into the small intestine, where they ferment sugars and fibers and produce gas. A breath test that measures hydrogen and methane can confirm it.

Frequently asked questions
Why do some patients say enzymes didn't work for them?
Usually because they stopped at one capsule. The dose has to be raised meal by meal until symptoms go away before anyone can say an enzyme failed.
Can a patient need more than one type of digestive support?
Yes. A patient who bloats after both protein and fatty meals may need hydrochloric acid with protein and bile support with fat. The food history guides each one.
Do enzymes help SIBO bloating?
Not on their own. When every food causes bloating, the problem is bacteria in the small intestine rather than a single digestive shortfall, and it needs its own workup.
