Bloating and SIBO: when a puffed belly is more than a nuisance

July 06, 20264 min read

Few complaints are as common as a puffed-up belly at the end of the day. Most of the time it's benign and passing. But social media turned an acronym — SIBO — into the universal culprit, and it's worth separating the common from what deserves investigation.

What causes bloating most of the time

Eating fast and swallowing air, chewing gum, drinking through a straw.
Excess fermentable foods in sensitive people (some fibers, beans, sweeteners like sorbitol).
Constipation: a backed-up gut bloats from buildup.
Very large or fatty meals.
Hormonal shifts (common around menstruation).

In other words: it's almost always behavior and diet, not a rare disease.

What SIBO is

SIBO stands for small intestinal bacterial overgrowth — too many bacteria where there should be few. It can cause bloating, gas, discomfort and changes in bowel habits. It's a real condition, but not every puffed belly is SIBO. It's usually linked to predisposing factors (motility problems, surgeries, certain diseases) and is diagnosed with specific tests, not home deduction.

When to investigate with a doctor

Persistent, intense bloating that doesn't improve with simple adjustments.
Accompanied by weight loss, chronic diarrhea, blood in stool, anemia or severe pain.
A marked, lasting change in bowel habits.

These signs take bloating out of the trivial.

What usually helps day to day

Eat slowly, smaller meals, identify individual triggers, treat constipation, move after eating and manage stress (which affects digestion). Trendy restrictive diets on your own can impoverish the microbiome — better done with a dietitian.
