Nutrient Issues

Protein.Post weight loss surgery patients are encouraged to achieve and
maintain an adequate protein intake. This can be a challenge for any patient
with the small size of the stomach pouch and food intolerances after
surgery.For patients with ESRD on dialysis, maintenance of protein
adequacy is a common problem. For patients with CKD nearing dialysis,
predialysis diet prescriptions frequently recommend limited protein. Protein
recommendations should be individualized based on comorbid chronic
conditions and laboratory measures of protein stores.
Renal diet versus post weight loss surgery diet. Foods normally encouraged
as part of a healthy diet for bariatric patients may be limited on CKD diet.
Lab values need to be monitored frequently. For patients with CKD and/or
ESRD, recommendations for limiting protein and minerals should be adjusted
based on laboratory measures.

One common nutrition issue for CKD patients is elevated serum phosphorus.
Foods high in phosphorus include whole grains, beans/legumes, nuts, and
milk. Following weight loss surgery, patients are generally encouraged to
consume these foods to help meet protein, fiber, and some vitamins/mineral

Elevated serum potassium may necessitate a decreased intake of certain
fruits and vegetables in addition to milk/dairy products.
Thus, limiting certain foods due to high serum levels of phosphorus or
potassium may necessitate a decrease in foods also high in protein, further
contributing to potential protein inadequacy
