I do a lot of macro photography, and recently have been pushing it with the addition of extension tubes. I notice that, if I increase the ISO beyond 400, the noise level becomes really noticeable. Is this an inevitable effect of the magnification?

Thanks, Dennis.

You can increase the exposure, a lot of noise can come from being slightly under. You wont really get rid of all of it. You can also use flash to help pump more light in.
Trouble is that I am running sequences of over 1000 shots and the flash overheats and shuts down, or the batteries go dead.

Then you will need continuous light source. You will need to setup a custom light balance.

To answer you question. If you take a light reading of the subject, the background will be under exposed. Noise will show up. This is true for most anything. A bird in a tree, the background is usually underexposed. Even if you use long exposure, some of the background will be under exposed. Noise will show. Adding the extensions, will lower the light hitting the sensor. So, you need to have more light.... someway.
