Effect of dietary fiber on complications of gastric surgery: prevention of postprandial hypoglycemia by pectin
Open accessAbstract
The dumping syndrome is a very troublesome problem to some patients after gastric surgery. Gel-forming carbohydrates have recently been used to modify glucose absorption. The addition of 14.5 g of pectin to a 50-g oral glucose load prevented the occurrence of hypoglycemic symptoms and maintained the blood glucose levels above control values by 64% at 90 min (P less than 0.002) and 46% at 120 min (P less than 0.01) in postgastric surgery patients whose 120-min values after 50 g of glucose alone had fallen below 50 mg per 100 ml (2.8 mmoles per liter). Breath H2 production, used as an index of bacterial fermentation of glucose, was abolished or reduced by pectin in all 5 cases in which this had previously occurred. A trial of 10 g of pectin per day prevented recurrent postprandial hypoglycemic attacks in the most severely affected individual. Pectin and perhaps other unabsorbable polysaccharides are likely to prove useful in the treatment of abnormal carbohydrate absorption after gastric surgery.

A number of short-term studies involving the ingestion of up to 15 g of guar gum or pectin with each meal have demonstrated the efficacy of these dietary supplements in slowing gastric emptying, reducing GI hormone release, improving hyperglycemia and controlling dumping symptoms.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
