Last Sunday night, we had a major argument right before bed ~10. At ~11:30 she went to get some water, and literally collapsed for quick moment after having heavy breathing. She then started sweating hard and had diarrhea. The next day she was tired, but since had no more breathing or sweat/diarrhea issues. We were trying to consider all symptoms from bad food, or stress attack or even heart. But with no more symptoms other then some tiredness since (it is now Thursday night) What would be causes of this? and should it be urgent for dr care several days later, or to wait to see if there are any re-occurences in the future?
