Gary; thank you for your response and yes it is somewhat helpful, but because we are still unsure of what is happening I am also still very confused.
My husband is very, very healthy and can pretty much eat anything he wants. He has no allergies and there is no food that causes him bloating or pain. He has never had any bouts of pain from his pancreas. His only issues are the loose, pale stools, and very frequent bowel movements with occasional gas and occasional oily stools. He is not on any special kind of diet right now mainly because we are not sure if he should be avoiding fat, protein, or carbs. We are just trying to avoid sugar as he does get spikes of high blood glucose levels, but only spikes up to 140-150. We have been trying a high calorie daily intake of 3000 calories at least per day. He seems to lose 1-2 lbs every 3 months, but has not gained any weight for the past 8 years. He is 5'8". I am getting concerned with his weight, but doctors don't seem to be and I don't really understand why. Just like being overweight can be unhealthy isn't being underweight just as bad too? Your information was helpful and I realize everyone has a different set of circumstances, so for us it is really hard to figure this out
