Hey,
What kind of shunt did you have put in may i ask?
Fixed pressure (High medium low)
Or an adjustable programmable one?

Reason I ask is that I currently have a fixed pressure one, I went into hospital the other week, feeling headachy (not bad headaches, just little ones) and Nauseous, which had continued for weeks...its now been about a month ongoing.
Well, I was given ICP monitoring over a period of 2 days, which suggested that I was overdraining, meaning the shunt was working too well and was taking too much fluid away from my head.
Therefore Im going into hospital tomorrow to be admitted again and have my shunt changed to a programmable to try and control this problem.

I wasnt aware that headache and nausea was a symptom of overdraining otherwise things would have clicked alot sooner than they did.

I do just hope, its your head adjusting from high pressure to a relatively normal pressure though. But of course, as anyone would say, if your concerned do just ask your neurosurgeon for his prospective of what is causing the nausea, should it be related to whats happening inside your head.
Good luck!!

Did they adjust your shunt? how you feeling after that?

I am 30 yrs old and I have a VP Shunt installed in 2004 due to brain lipoma between the 3rd and 4th ventricles... for the last month I've been having nauseas and presure in top of my head that feels like someone is pushing me down, and I feel dizzy... I hope is not that
