Motility Is a Nerve Signal
The stomach empties because the vagus nerve tells it to. When vagal signalling is impaired — by diabetes, viral illness, surgery, dysautonomia or chronic stress physiology — food sits, and everything downstream backs up with it.
That backlog is also why gastroparesis and small intestinal bacterial overgrowth so often appear together: stagnant contents are a growth medium.
Why It Is Mislabelled
Early fullness, nausea, bloating and unintentional weight loss are frequently attributed to anxiety or disordered eating, particularly in younger women. A gastric emptying study is the objective test, and it is often ordered late.
Where a cause is not obvious, the next questions — autonomic function, blood sugar control, infection history, mast cell activity — are rarely asked at all.
What a Root-Cause Look Adds
We assess blood sugar and insulin, autonomic function, thyroid status, gut infections and overgrowth, nutrient deficiencies that impair muscle and nerve function, mould exposure where history suggests it, and connective tissue involvement.
Nutrition strategy runs alongside this — meal texture, volume and timing make the day workable while the drivers are addressed. Any significant weight loss or inability to keep fluids down is a medical issue that belongs with your gastroenterology team.
