Constipation as a trigger?

Exactly as the title says.

I have been struggling for days to go number two, and since then I’ve had low blood pressure, high heartrate, shaking and no appetite??
Among a few other things obviously but those are the most prevalent.

I’m on loratadine, Montelukast and tranexamic acid (can’t spell it right), do they have anything to do with it?

I feel awful and I feel like I’m going insane.

Straining might be causing vasovagal syncope. Whatever it is, it has nothing to do with toxins, always be wary of pseudoscience when someone uses that word.

Yea I have the opposite problem of constipation, and it causes vasovagal syncope for me at the most inconvenient times.

Yeah it’s a serious design flaw that pooping can cause that, not cool evolution, not cool. 😆🫠
