Just been told my kidneys aren't functioning at 100% after routine blood test results - 51%. Dr then told me they hadn't been functioning at 100% for the last 10 years when they were 70% and then 2012 at 61% and that that if they reduced to 30% I would be referred to a specialist. She said it was my immune system, I asked why I hadn't been told previously and she said that there wasn't any reason to tell me. I said I was a little surprised. I spoke to her about some ongoing back problems (almost three years affecting the whole of my left side), ongoing fatigue (a few years) she asked if I took ibuprofen or aspirin and I said no, she asked me about my diet which I said I haven't had an appetite for a couple of years and she then said she was going to order some more blood tests as my cholesterol has gone down significantly she said there may be an underlying cause. She said the good news was I'm not diabetic. I have low blood pressure so she told me to drink plenty of water but I need the loo straightaway to add salt - which is what happened but I haven't added salt. She also told me to eat plenty of fruit and veg.
I came home a bit bewildered and came across this site so you can imagine my surprise at my dr's apparant casualness at telling me my kidney function is 51%. I have low vitamin d and asthma otherwise healthy. I have had a metallic taste in my mouth fir several months which I forgot to mention to dr but reading here indicates that may be significant.
I'm clueless about food and have been searching online for a dietician that can help me but haven't found one yet - I'm Midlands based.
The dr didn't go through the blood test results in detail but I can see from posts here references to various results. I can access some of the results online - just need to understand them!
Sorry for the long post but wanted to get as much info in as possible.
I'm female, 55 and would appreciate all and any guidance on next steps.
