Bear said:I was going to start another thread for this, but I have question related to the diet. I received some concerning news that I'm showing signs of kidney disease most likely related to taking medications, specifically Lithium and the amount of water I drink due to the dry mouth from the medication. The indicator that shows I'm having problems is the GFR (Glomerular Filtration Rate) that has been read twice recently at 56 where 60 and above is normal. Blood pressure was normal. Blood sugar level was good at around 85 and I had no protein in my urine. I've been taken off lithium and was given a packet of reading about the condition and what to do in terms of eating. The information says to limit sodium and potassium and to eat a smaller amount of protein than normal.
I've been on the diet for three weeks and have been supplementing both sodium and potassium, so now I'm not sure what to in terms of supplementation and the diet. I was kind in a shocked state when I was told about the issue and didn't ask about the diet I'm on. The only mention of the kidneys I remember in the reading was in reference to the only time that the Atkins/high meat diet has shown to cause problems with the kidneys is when someone has a pre-existing kidney condition. The reference was in 'Life witout Bread' or 'The Art and Science of Low Carbohydrate living', but I loaned them out and not sure which one it is in.
I'm going to start digging and searching the internet for information on what I can do for the condition and hopefully find something in relation to the diet and kidney problems. If anyone knows a good place to start or can point anything out that is useful to read, it is greatly appreciated.
It is particularly the glycated protein that is problematic and damaging for the glomerular filtration, that is, the caramelized proteins. So restricting sugar is still a way to go, but with a compromised kidney function, you'll have to be very careful with your protein intake. It is not only mainstream news, but this issue is brought pretty much in all the low carb books so far. Jonny Bowden from Living Low Carb says the low carb diet is contraindicated in cases of compromised kidney function.
You'll have to moderate your protein intake and network with your doctor to find the recommended amount of protein per day. Then, you can adjust the diet around that, getting more fats from butter snacks, coconut oil, etc. I find it possible to restrict protein and carbs and get most of the energy intake from fats. You can eat green veggies or mushrooms as a means to eat more fat.
There are many centers in the US working with patients and offering ketosis as a line of treatment. Perhaps you can contact one and explain your situation?
If you have reduced glomerular filtration, stop taking potassium and sodium supplementation ASAP. It is dangerous. If the potassium doesn't get filtrated normally, it will accumulate to the point where your heart can stop. You'll have to monitor this closely with blood tests. Depending on how much your glomerular filtration is compromised, potassium can accumulate fast. Be careful with all the minerals.
