Dr. Ronald W. Hamner M.D.'s Expert Contributions
My mother is a CKD patient and her urine output is decreasing. What could this mean?
Decreasing urine output may mean kidney function is worsening to the need for dialysis. However, dehydration is common in people with CKD from poor appetite. If the legs are swollen and urine output drops, call your doctor. If legs are not swollen and urine output drops, try extra 1-2 glasses of water or chicken soup. READ MORE
Are there any supplements that will strengthen my mom's kidney function?
Kidney function is better served by avoiding foods and substances that increase work for the kidney. For example, phosphate almost totally excreted by the kidneys. To reduce the amount of phosphate work load for the kidneys, avoid colas, hard cheese, large amounts of brown beans and phosphate preservatives READ MORE
