A 44-year-old member asked:

Is it normal to experience a lot of nausea while performing a valsalva maneuver?

Soemtimes: When some people swallow or bear down, the vagus nerve is overly stimulated and creates a nausea sensation. Usually this person has an excessive gag reflex as well. Try not to do a valsalva maneuver unnecessarily..

Alternobaric vertigo: Another cause for this problem can be unequal clearing of the ears. This can happen if you valsalva when you are congested. One eustachian tube opens, allowing greater pressure to develop in the middle ear on one side. The difference in pressure between the two middle ears "confuses" the inner ear causing severe vertigo and nausea. The condition is known as alternobaric vertigo.
