Sorry I didn't reply to your kind words before this - I didn't realise that there had been a response. I had another blood test today, but haven't had the result yet, of course. I also saw a medical consultant at the hospital about my liver problems but they just want to leave everything with my GP. My GP is a very kindly man, but he is the only one available here and he seems happy just to keep a watching brief over these various ailments. He does say that he is concerned (actually more concerned about the possibility of my liver cirrhosis resulting in cancer than in my kidney problem) but no treatment is on offer. I can't help thinking that the large proportion of protein I have been consuming whilst low-carbing might have had an effect on my kidneys. No point asking about that because no-one here believes in low-carbing and they are bound to say "I told you so..."
