merpaperpleIt's not necessarily late dumping syndrome, this is the dietary guideline for early dumping syndrome too. Based on UpToDate and ScienceDirect this is how it works:
Absent or dysfunctional pyloric sphincter
-> food is rapidly emptied from the stomach into the small bowel
-> hypertonic solution forms in the jejunum
-> rapid fluid shifts from the plasma into the bowel
-> hypotension and SNS response (eg. colicky abdominal pain, diarrhea, nausea, tachycardia)
Simple carbohydrates are more hypertonic, I think.
helloYep, seems that because the patient has prediabetes, he should avoid eating excessive starchy foods.
