Can general anxiety develop vasovagal syndrome?

[star68]

Recently I have noticed a feeling of dizziness while pressing to defecate, it happens especially when I am constipated and it's very hot. Then another time I had another episode while doing power walking that left me very shaky, nauseated and edgy, I didn't faint but nearly fainted. Then I have noticed when I am very tired especially emotionally I feel light headed.
I have generalized anxiety since I was very young and I wonder if over the years of panic and nervousness I have damaged my nervous system to the point that I suffer from this condition.
Could someone advise me on the subject?
Thanks

Both of the above posters make good points, but I think since this is a recent development with symptoms of dizziness, nausea, shakiness, nearly fainting and feeling light headed when you're tired, I would recommend seeing your doctor for a check up.
This more than likely IS a matter of keeping yourself well hydrated and adding a stool softener, but I think erring on the side of caution is safer and knowing for sure will eliminate any anxiety this may be causing you.

The vasovagal response isn't a syndrome, it can happen to anyone.  There are people more susceptible to it, but for the most part, it's not going to be affected by anxiety, it's a physiological response.

Now, your anxiety certainly can be exacerbated by those sensations, which adds to your overall poor feeling.  If you've had issues with this before, you need to be sure you're doing some things to try to prevent it, like taking stool softeners and preventing constipation.  Also, you need to exercise caution when bearing down.  If you're taking stool softeners, the idea is you won't have to "work" so hard to have a bowel movement.

Hang in there, certainly keep in touch with your doctor, especially if this happens with any regularity.
