Key Takeaways
- Sweating and feeling sick during a bowel movement is usually caused by a vasovagal response, a nervous system reaction to straining.
- This reaction can cause dizziness, nausea, cold sweats, and even fainting, a condition sometimes called poop syncope.
- Common culprits include constipation, straining too hard, dehydration, and standing up too fast afterward.
- Most cases are harmless and go away with better bathroom habits and hydration.
- See a doctor if you faint, have chest pain, or feel sick every time you have a bowel movement.
