Overview

When stool moves slowly through the colon, bacteria have more time to ferment residual nutrients, producing excess gas. Additionally, the retained stool itself causes physical distension, creating a sensation of bloating and fullness.

Possible Causes

Inadequate Fiber/Fluid

common

Low fiber intake and dehydration produce hard, slow-moving stools that promote gas accumulation.

IBS-C

common

Constipation-predominant IBS involves sluggish motility with visceral hypersensitivity amplifying bloating sensation.

Hypothyroidism

less-common

Low thyroid function slows gut motility, contributing to constipation and secondary bloating.

When It Is Serious

New-onset constipation after age 50, blood in stool, persistent narrowing of stools, or unexplained weight loss.
