my husband was taken to emergency last night they said he had a trapped vagus nerve. He had excessive vomiting and diarhea, he was also going into unconciosness, this happened about 5-6 times. Whilst in the hospital they took blood and discovered he had a high potassium .
Hello, High potassium is not related to the vomiting and diarrhea. The loss of conscience could be related to low blood pressure, due to deny Chat Doctor.  For this reason, I recommend taking plenty of fluids and stay at bed rest. A food intoxication or gastroenteritis could mimic this clinical situation. You should discuss with his doctor on the above issues. Hope I have answered your query. Let me know if I can assist you further.
