What Our Protocols Say

Bloating-Dominant Limit or avoid

Alcohol irritates the gut lining and affects motility. Beer is particularly problematic due to fructans.

Tip: If drinking, choose dry wine or vodka with soda water.

Constipation (IBS-C) Avoid (dehydrating)

Alcohol dehydrates you, which worsens constipation significantly.

Tip: If you drink, increase water intake substantially to compensate.

Diarrhea (IBS-D) Strictly Avoid

Alcohol is a gut stimulant that directly triggers loose stools and urgency.

Tip: Avoid completely during your symptom management phase.

Mixed (IBS-M) Avoid

Alcohol has unpredictable effects and can swing symptoms either direction.

Tip: Track carefully if you choose to drink; most do better avoiding.

Post-SIBO Recovery Avoid

Alcohol disrupts gut healing and can promote bacterial growth.

Tip: Avoid for at least 4-6 weeks post-treatment.

Stress-Triggered Avoid

Alcohol disrupts sleep and increases anxiety — both worsen gut-brain symptoms.

Tip: Avoid while working on nervous system regulation.
