Why Am I Bloated After Sourdough
You switched to sourdough because it was supposed to be the healthy option. Now you're bloated every time you eat it and nobody can explain why.
Why it happens
Sourdough fermentation reduces but does not eliminate gluten and FODMAPs. For people with non-coeliac gluten sensitivity or IBS, even the reduced levels in sourdough are enough to trigger fermentation by gut bacteria — producing gas and bloating within two to three hours. The Weizmann Institute's research on 800 people confirmed that gut responses to identical foods vary wildly between individuals. What's fine for most people can be a consistent problem for you.
The delay between eating and bloating — two to three hours — makes the connection almost impossible to spot without data. Most people never connect it because they ate the sourdough at breakfast and feel bloated at lunch.
How Normal finds it
What this means
Normal found this pattern across 8 data points in 3 weeks. No elimination diet. No food diary. Just telling Normal how you feel.
The point is not that why am i bloated after sourdough has the same cause for everyone. It is that your body leaves a trail in ordinary days: what you ate, how you slept, how stressed you were, how fast you moved through the day, and when the symptom showed up.
Normal is built to catch those patterns over time, so you stop guessing from generic advice and start seeing what reliably changes how you feel.
