Hi Julie,
Information from the Combined Health Information Database (a health education resource from a number of federal goverment health agencies) reveals that dumping syndrome occurs when undigested food reaches the lower end of the small intestine causing an influx of fluid into the gut and, ultimately, rapid flushing of the bowels. It seems your husband has a tell-tale symptom of "late" dumping--low blood sugar that occurs one to three hours after a meal. I'm sure the docs mentioned the importance of eating several small meals per day, watching refined carbohydrates and sugar alcohols, as well as the value of consuming liquids between--not at--meal times. That's pretty standard stuff when it comes to treating this. You might also get recommendations from a registered dietitian who specializes in diabetes care. Contact the American Dietetic Association at 800.877.1600 and ask for an RD with a CDE credential (certified diabetes educator). You may also wish to consider adding digestive enzymes to your husbands nutrition plan. These enzymes help to break down the food in the stomach, therefore, reducing the chances of having large amounts of undigested foods travel to the lower gut. I hope this helps.
Best,
