My husband has been diagnosed with chronic kidney disease in Dec 2016. He has been afib since 1992. When they diagnosed CHF, they added Oasis 40 2x daily along with his warfarin and lowered his digoxin too 125 mcg. He is restricted to 40 oz of fluids daily. How does this affect his kidneys?

I am not familiar with the drug “Oasis”.  Patients with heart disease also commonly have chronic kidney disease (CKD).  The doses of his medications will need to be adjusted for his kidney function and he will have to be monitored … Continue reading

I see you recommended the DASH diet but that diet specifies the need for foods rich in potassium. I had understood that potassium, like sodium, are both to be kept low. Or does one only even have to think about that if blood tests suggest that the kidneys are not processing those minerals? CKD and diets seem to be a contradictory minefield. Does one need to adjust diet to prevent stressing the kidneys or does one only have to adjust if the kidneys have deteriorated to the point of not processing these minerals, as shown by blood test results? (My GFR was 46 at the most recent test.)

I recommend the DASH diet for patients with chronic kidney disease (CKD) Stage 1, 2 or 3.  In most cases, potassium is not a problem when the estimated glomerular filtration rate (eGFR) is greater than 30 milliliters per minute per … Continue reading

My father has diabetes but it is controlled now. His creatinine level was 5.4 four months ago. Now it is 4.2 after taking treatment. Is it a sign of improved kidney functioning than before? But this protein level is now 150 which was 52 before. Potassium level is 5.9 now. He is 57 years old. I want to know that is it possible to reverse this process to normal stage?

I am unable to make a specific diagnosis based on the information that you present.  Your father should be carefully monitored by his physician.  There may be some room for improvement, but I cannot provide a prognosis based on the … Continue reading

I have a gfr of 59. Is it ok to do water fasting with stage 3 kidney disease?

I am not familiar with the term “water fasting”.  If this means dehydration, this is likely not something I would recommend.  I recommend hydration with plain water.

I HAVE STAGE 4 CKD- WHICH IS BETTER WHITE RICE AND ENRICHED WHITE/WHEAT FLOUR OR BROWN RICE AND WHOLE GRAINS?

I don’t know of any information that says that different forms of rice and wheat have any effects on the kidney.  I believe that whole grains and brown rice may be better for patients with diabetes and kidney disease, but … Continue reading

Hi. I have IgA Nephropathy, with a eGFR of 70-ish. I eat healthily with lots of fruit and veg, low sodium etc. Unfortunately my potassium levels are high 5.7. I am concerned that to change my diet to low potassium will be a diet less supportive of low blood pressure. What would you suggest? Also I was seeing a kidney consultant a year ago but was discharged as kidney function was not too bad. My GP in my last OPA denied that the kidneys excrete toxins, denied that creatinine was measured as a marker for small molecule filtration and seemed generally defensive and dismissive of what I had learned about my own condition. I am concerned that she does not have a good understanding of this condition. I work in a specialist mental health team and I am very aware that GP’s lack in depth knowledge of subjects as they need instead to have some understanding of terrifically broad subjects. I am however concerned that her advice may not necessarily be well informed. I am also concerned that one should also be careful with internet sources.

Your potassium should generally be in the range of 3.5 to 5.5 milliequivalents per liter (mEq/L).  Your potassium is mildly high.  I might suggest that the test be repeated to see if the potassium is consistently high.  If it is … Continue reading

I have been diagnosed with IgA nephropathy and is in stage 3 CKD. My question is related to diet. I have observed from experience that if I follow a low protein diet, my egfr and creatinine seems to be in better level. When I increase food intake there is a decrease in egfr and increase in creatinine levels. My nephrologist insists not to worry about diet or protein at this stage. Is it better to take less food and be underweight or is it better to take enough food and worse the blood results?

I agree with your physician.  I am not a fan of low protein diets.  This can lead to malnutrition which can have other ill effects on your body.  I suggest that you follow a low salt DASH diet.  You can … Continue reading

I am looking for a dietician who can create a meal plan for me to follow. I cannot grasp the concept of creating one myself. Where can I find a reasonably priced renal dietician?

There should be registered dietitians in your area and the best way to access them is to discuss this with your physician and seek a referral to a dietitian who could review your current diet and make suggestions.  Your primary … Continue reading

Hi, my mother is in stage 3 kidney disease. She has been laxative dependent for many, many, many years. I have been reading and learned laxatives aren’t safe for her. She is 77 years old and eats very little fiber. Is there a fiber powder supplement that is safe for her to use, such as benefiber?

Fiber laxatives are safe, including “Benefiber”.  Laxatives to avoid are mostly magnesium containing laxatives such as Milk of Magnesia and Magnesium Citrate.  Mixtures of Polyethylene Glycol (PEG) with electrolytes are also safe when mixed in water.  Brand names for PEG … Continue reading
