RYGB
• Diet is healthiest of all bariatric surgery patients
MALABSORPTION after RYGB
“doctor: I’don’t like burgers anymore”
• There is restriction but no vomiting
• Especially fat malabsorption
• Enhanced by longer biliopancreatic limb
• Carbohydrate are absorbed in the roux limb and as FFA in
• But some patients make diet mistakes

• DIET DEPENDENT (to fat)

• Diet is healthiest of all bariatric surgery patients

• There is restriction but no vomiting
• But some patients make diet mistakes
• Dumping is far more less

Plasma Bile Acid Profile after RYGB
ILEAL INTERPOSITION
• Higher plasma bile acids after RYGB (although exact
mechanism unknown)
• Correlated with better metabolic profile
• Bile acids increase energy expenditure in BAT1

ILEAL INTERPOSITION
An ileal interposition with a diverted sleeve gastrectomy is an
effective operation for the treatment of type 2 diabetes mellitus
patients with BMI 21-29.

WEIGHT LOSS is IMPORTANT
gastric plication
Failed conservative treatment
SURGERY
WEIGHT REGAIN IS STRONGLY ASSOCIATED WITH RELAPSE OF DM
Lower preoperative BMI is also contributing factor
Possible mechanisms:
-Increased calory intake
-Increased fat mass
-Adaptation of the gut
Further research is needed
