Thanks for the query.
can increase the urine output. However it needs to be administered under the supervision of a nephrologist
2) The dose of cresp has to be adjusted by the nephrologist to target a Hemoglobin
3) Citrus fruits, bananas, tomatoes , green vegetables are rich in potassium. One of the ways is to cut and boil the vegetables and discar the water before eating.
Hope this helps
