will sinus drainage cause dizziness and nausea

Hi,

It shouldn’t but every person is different so everything is possible.

Have you experienced dizziness and nausea during sinus drainage? If you did maybe you should inform your doctor about this. It is probably nothing that should concerns you but there is no harm in asking.

And dizziness and nausea can be caused by various other things for example low blood sugar, lack of sleep; some types of foods and of course some more serious conditions.

Also you could be suffering from lack of iron or some vitamins. If you determine this is the cause of nausea and dizziness try to improve your diet with iron and more fruit. You can take some supplements as well.
