● Eat slowly for 20 minutes or more.
● Food should be well chewed and should be consumed in
small volumes. After surgery the stomach can only hold 1 – 2 ounces of food or fluid, but can expand up to 4 – 5 ounces.
● Liquids should be consumed 30 minutes before meals or at
least 30 minutes afterwards.
● Proteins should be consumed before fats and
carbohydrates, in an amount of at least 60 g
daily, which is above the daily requirement for women
● Anyone who has gastric banding may develop iron and vitamin B-12 deficiencies.
● Roux-en-Y gastric bypass procedures can cause nutrient deficiencies for iron, calcium, folic acid, and vitamin B-12. Dumping syndrome is common with this surgery which includes nausea, vomiting, abdominal pain, cramps, diarrhea, dizziness, and lightheadedness.
● Biliopancreatic diversion procedures have a greater risk for nutrient deficiencies.
● Fat absorption and lactose intolerance can cause concerns.
● Dehydration and gallstones may develop.
● A vitamin/mineral supplement is generally recommended.
Dietary counseling is extremely important to the success of the surgery. Regular appointments, during the rapid weight loss phase (the first 6 to 12 months), are necessary.
