Why do I bloat after meals?
Bloating after meals can have several causes. The timing, meal patterns, and other symptoms can help us understand what may be contributing.
What often contributes
Eating habits and swallowed air
Eating quickly, drinking through a straw, chewing gum, or eating while stressed or distracted causes excess air to enter the upper digestive tract, producing gas and a distended feeling after meals.

Bacterial fermentation in the colon
When carbohydrates and certain fibers pass through the small intestine without complete breakdown, resident gut bacteria ferment them in the colon, producing gas that can cause noticeable bloating, cramps, and fullness.

Food intolerances and transit changes
Difficulty breaking down specific sugars (like lactose) or proteins, as well as slow motility or constipation, make it harder for gas to move through the digestive tract normally, leading to post-meal pressure.

Is this the only thing going on?
Take a quick look across these three questions:
Are you waking in the night or waking unrefreshed?
Do you hit an afternoon crash or reach for sugar to get through the day?
Has your cycle, mood, or tolerance for stress shifted recently?
If two or more are a yes, this may be one piece of a larger pattern.
