The Digestive & Absorption for RYGB Surgery comments that I provide to my bariatric surgery patients can be helpful along with the Bariatric Surgery Nutrition Guide.

Digestion of carbohydrates and protein is very dependent on brush border enzymes in the small intestine (1). Deficiencies in these enzymes are common post surgery in Roux-en-Y gastric bypass patients. Symptoms of gastro-intestinal need for digestive enzyme replacement are: intestinal gas, abdominal discomfort, flatulence and diarrhea.

Adding the probiotic yeast Saccharomyces boulardi and a bifidobacterum + lactobacillus probiotic may improve digestion, absorption and gut health (2).

Saccharomyces boulardi SACC2 60 capsules (take 1 or 2 per day)
Vital 10 (5+billion) VIT56 100 capsules (take 1 to 3 per day)
Open the capsules and stir them into a shake or applesauce daily.
