Hemo and neusea

[BigSteve]

What causes nausea during hemo? The toxins are being filtered out. Is it  blood pressure?
My problem, which is minor, is that about half way through my in-center hemo my stomach
get "queasy". I don't vomit as many dialysis patients do, but the feeling stays for hours.
I can only eat a small amount of something light when I get home.

BigSteve, Our clinic told us that most cases are probably due to hypotension (low blood pressure). We did home-hemo and Len would get that feeling half way through and I would turn off the UF for about 10 minutes and he would be fine for the rest of the treatment. Hope this helps.

it from taking off too much fluid, causing your blood pressure to drop to low. it can cause nausea and cramping. basically you are becoming dehydrated. try cutting your uf rate by .5 (even if the tech tries to tell you, you can't you have the right to tell them exactly how much to take off.)

Yes, this 10 minute "break" gives the fluid a little bit of a chance to move out of its hiding spots and into your bloodstream. We have also had a small amount of hypertonic saline used. I believe that the saline actually encourages the fluid movement out of the hidng spots. Perhaps someone more technical than I can better explain the mechanism.

I had a similar problem when I first started dialysis. I never gained any fluid so my bp would nosedive when I first started. The problem was solved by hooking me "straight up". In other words, starting the saline as soon as blood started pulling.
