10 Causes of Fainting
Reviewed: Dr. Gromatzky
Cause #6: Diarrhea
It’s not likely that diarrhea itself will cause you to fall unconscious. However, there are a number of conditions that cause diarrhea that are also known to cause fainting.
Viruses, medication, food, allergies, stress, and other medical problems can all contribute to both diarrhea and fainting. If you have experienced any sudden changes in your health, or if you’ve made any drastic changes in your life – such as taking a new medication – and are experiencing diarrhea, be cautious of losing consciousness during your day. Diarrhea can also cause dehydration and as we know, dehydration can lead to fainting.
