Thanks for posting your query.
as you are having only one kidney
so your renal system is compromised. GFR is much reduced, and Vitamin D deficiency and anemia
are also related to kidney.
You should watch their protein consumption to avoid taxing the kidneys as they heal.A low-cholesterol
and low-saturated-fat diet is good.High-potassium foods such as bananas, kiwis, avocados, prunes and prune juice, tomato juice and sauce, nuts, dried peas and beans, chocolate, orange and orange juice should be avoided. Vitamin D and Calcium supplements
would be helpful.
Hope it helps.
