Hi Lee Ann,
I have never heard anything about the connection between MCV and folate/B12, previously. My nephs and dietitians never bring this one up. They mainly only speak about values related to Hgb/iron sat., PTH/calcium/phos., K and clearance values. I try to study one lab value at a time when the time is appropriate. I looked up MCV on my reports and found that mine has always run between 100-117 when the scale top value is 96. Therefore, there has always been a H for high by MCV. How high does MCV have to be to indicate a problem?
Re the homosysteine presentation at DiatxZN, to determine if one has high homosysteine they are to test B6, B12 and folic. Does this problem have anything in common with the high MCV issue?
Re zinc and appetite. Even now that I am on nocturnal, appetite is still an issue. I don't have a poor appetite, always have an albumin over 40, but what I do have is a picky appetite. When I say picky what I mean is, prior to CKD I was a person who had a very good appetite as in there were few foods I did not like and was not picky like ppl who dislike so many foods. Also, I could go for anything that was for supper, or anything that was on the menu. But ever since CKD, I have had a very selective appetite in that I can look at a menu and barely one single entre appeals to me, but fortunately I seem to be able to find just one choice I can go for. And whereas the thought of let's say a hamburger makes me gag on Monday, that might be exactly what I want to eat on Tues. Usually, as far as the meat portion of a meal, I am completely turned off by all meat choices but one per day, but the one I am in the mood for works fine. Its very weird. It is sort of like being a pregnant woman. The good thing is, I do eat well if it is what I am in the mood for, but each day it is a task to figure out what I feel like eating. I usually never know until the afternoon what that will be. Can never plan a weekly menu. So, I would definitely call this an appetite problem, but I manage ok.
Also, there are times when appetite is down and it goes on this way for maybe most of a week. It's sort of like I get bored of food, but this may be due to a higher need then some to have something that is well prepared and a new dish, unlike the rest of my family who seems to be able to eat whatever is available. I never eat something that I am not in the mood for or then it will taste really off to me. So, I would definitely say that CKD has affected me this way. Of, course, non-CKD ppl could have similar issues, but I would say it is more pronounced in me. Whether this calls for a little zinc or not, I don't know. One dietitian told me that one would have to take a lot of zinc for it to be toxic. Notice the renal vitamins that contain zinc either contain 15, 25 or 50 mg. Have no idea how toxic that is to a kidney patient. Is it zinc that is also recommended for hair loss? I have noticed that selenium as well as copper is also in some renal vitamins. What would be the purpose of this?
I have never been tested for serum Vit. D. I asked my dietitian about D3 and she said what you are saying here that I should be tested for Vit. D since I take Hectorol to make sure the addition of D3 would not be too much added D. But isn't D3 a different type of D that the body needs? Do you know of a separate D3 supplement should it work out that I take this along with Hectorol? Well, one thing is for sure, I will be glad to settle this issue knowing I have made a better choice in a renal vitamin, although I am not positive of anything here as it seems like such a vague subject. If it can't be tested to know what a person's vitamins levels are, it doesn't sound like a very exact science.
