Dizziness when surfacing

[reynoldss2]

My husband and I are newbies. We have worked through many of the little things from being new but can't seem to find a solution to this one.
When my husband starts to ascend he becomes very light headed to the point of almost passing out. He has tried ascending slowly and looking up to the surface so that his ears are clear. We have asked various dive instructors and they can't give us a reason why it's happening or what to do to stop it. Can you help?

Doc Vikingo & Doc Saturation in the medical section of this board may have a few insights medically.

From my own experience, I have sometimes felt dizzy when my ears have not both cleared properly. When one of them clears, and the other does not, it turns into a merry-go-round under water, which is most unnerving if you are not used to it. It seems to happen to me when I have a case of a-symptomatic flu, in other words, I am sick with the flu, but I cannot tell that I am sick, until I go scuba diving and I try to clear my ears.

When it happens, it serves as a warning to me, that I should not be diving right now, until I get well again.

It's called alternobaric vertigo. ( Do a search, there's a lot on it )
It happens to me sometimes when I don't wear a hood and get down into the colder water. It vanishes when I surface.

Thank you for your help. At least now I know that there is such a thing and can do some research. I really appreciate the scubaboard. This has been a godsend for us.
Thanks again.
