for those with POTS - possible source of nausea

[Guest guest]

This is an old article but I found it illuminating:

http://www.ncbi.nlm.nih.gov/pubmed/15742822

Conclusions: These data indicate that reductions in cerebral blood flow precede

the development of nausea. Further work is necessary to determine what role

cerebral hypoperfusion plays in motion sickness and whether cerebral

hypoperfusion can be used to predict the development of nausea in susceptible

individuals.
