Polycystic Kidney Disease (PKD) Support Group
Polycystic kidney disease (PKD) is a progressive, genetic disorder of the kidneys. It occurs in humans and other organisms. PKD is characterised by the presence of multiple cysts (polycystic) in both kidneys. The disease can also damage the liver, pancreas and rarely the heart and brain.

Why would a doctor refer you to a dietitian if diet plays no part in PKD? She told me to restrict my sodium, watch my potassium and phosphorus intake, but nothing would change my lab reports.
Does anyone have any dietary advice?
That sounds like a pretty useless dietician. I have reduced the amount of potassium in my diet and my serum potassium figure fell: a direct result. The same happened with my phosphorous. I have kept my sodium low for years and this is reflected in the fact that I still take only the very minimum dose of BP medication. It's so low that nobody else takes this dose and the pharmacist has to order it specially. None of this may improve function but it can limit damage being done elsewhere in the body, reduce itching if you have that problem and make you feel better. I think her attitude is poor. Which things do your lab reports indicate need attention?

If you eat a high protein meal prior to blood tests and are somewhat dehydrated, this will put your creatinine level up.
"Food intake can affect the bodys acidbase balance through supply of acid precursors (i.e., noncarbonic acids, such as sulfuric acid) or base precursors (i.e., alkali salts from organic acids [OAs], such as citrate and bicarbonate). In general, meat, fish, cheese, grain products, and rice are relatively strong net acidifying foods, which are also high in phosphate, whereas fruit (apples, peaches, and raisins), legumes, vegetables (spinach and cauliflower), and potatoes are relatively strong net alkalinizing foods, and foods low in acid, such as potassium, are potentially renal-protective. Our contemporary Western diets are shifting from relatively alkalinizing toward more acidifying. The consequence of high DAL is a state of metabolic acidosis, which is a common complication of advanced CKD.14 Our findings suggest that high DAL plays a role in the progression of kidney disease. They reinforce the findings of earlier studies that have shown beneficial effects of alkali supplementation in slowing the progression of kidney disease7,8 and studies documenting the association of metabolic acidosis with CKD progression.15,16
We noted an association of DAL and progression to ESRD for participants with albuminuria. Our findings are in accordance with previous studies that have shown high consumption of meat food groups (i.e., each serving per day greater intake of the sum of red meat, processed meat, poultry, and fish) to be positively associated with albuminuria.17,18 By contrast, a dietary pattern characterized by high consumption of fruits and vegetables (i.e., each serving per day greater intake of the sum of fruits, fruit juice, vegetables, nuts, and legumes) was inversely associated with albuminuria. Because albuminuria is a major risk factor for ESRD progression, our data suggest that higher DAL may lead to kidney injury, which may portend progression to ESRD."

The only trouble is, once your potassium levels start to rise (with declining function), it's largely the alkaline foods that have to go. That leaves nothing to eat at all!
Overall - not too shabby. I do have light pain most of the time if I stop and think about it, but it's what I'd call "non-disruptive" pain. It doesn't keep me from concentrating at work, etc... Just kind of there. (Cyst ruptures are the exception to this pain rule. I've had blood in urine maybe 15 times over the years but only a couple have come with bad pain)
Bending/twisting certain ways is a no-go for me now. Kidneys around 20cm each, and I think maybe they are starting to encroach on other organs (i.e. stomach).
Overall, for me the symptoms have been way better than described.
Double-nephrectomy and simultaneous starting of hemo on the other hand, might be a little less fun. But it's part of the plan. It's all good...
First of all welcome to the group. I hope you'll feel a little better after exploring some of the posts here. No, this is not all in your head. My function is 28% and my consultant says I can can expect to experience the fatigue and pain that you describe. Some people have nausea, too, for various reasons. I have everything that you list, too. Over the years, I've seen that a number of people have doctors who believe PKD does not cause pain. They are very wrong. Your kidney function is at the level which requires you to start thinking about renal replace therapy options. Refuse to see your doctor's PA again. Ask to see your doctor, or see another doctor. You deserve better. You may also benefit from seeing a renal dietician. Let us know how things go.
