In brief: Various
Your autonomic nervous system (ANS) controls virtually all the organs and systems in your body.
If your parasympathetic (pns) is hyper, you could have urgent urination, diarrhea, gas, bloating, watery eyes, allergies, asthma, low blood pressure. The vaso-vagal response is caused by excess pns tone which will lower pulse and BP at the same time. The vagus nerve is a major player in pns.
