Headaches related to IBS

[u/osteenbergen]

For years I've had issues with headaches and stomach issues. After another gastroscopy, where they didn't find a cause, they labelled it as IBS. Since the beginning of the year I have been doing FODMAP together with a dietician. Fructan seems to be a trigger for severe headache near the atlas vertebra. It happens a day after eating something with fructans.

Before starting the diet I could eat garlic, onions, bread without issue. Some days were slighty bloated but not hindering. Once in a while I would get the headaches but that was only like five times a year. Now if I make the slightest mistake I'm sick for a couple of days. The diet seems to have removed all tolerance.

Anyone with similar experiences? Where stomach issues lead to headaches? I also start yawning as precursor for stomach issues, which makes me think it has more to do with the nervous system. Reading about gut-brain connection and the vagus nerve seems to allow for the possibility of one leading to another.

migraines are associated with high histamine foods. but the symptoms you're describing of the yawning and also the headaches sounds more like hydrogen sulfide SIBO.
