1.   All studies were performed in the fasting state.

2.   The test was done in the fasting state.

3.   Increased breath hydrogen excretion after the ingestion of glucose and increased breath hydrogen excretion in the fasting state, is a useful indicator of intestinal bacterial overgrowth.

4.   In functional diarrhoea there is more to and fro movement of intraluminal contents in the fasting state than in normal controls.

5.   Thus detection of a persistent tachygastria in the fasting state is highly suggestive of a neuropathic basis for the pseudoobstruction.

6.   We were impressed that the tachygastria in our patients with neuropathic pseudoobstruction was both persistent and raised consistently in the fasting state.
