Can Stress Cause Nausea and Vomiting?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 22nd, 2026.
Yes, stress can directly cause nausea and vomiting through the gut-brain connection. When you're stressed, your body releases hormones like cortisol and adrenaline that can disrupt normal digestive function. The vagus nerve, which connects your brain to your digestive system, becomes overstimulated during stress responses. This disruption slows gastric emptying and increases stomach acid production, leading to nausea. Studies show that up to 40% of people with chronic stress experience regular digestive symptoms, including nausea and vomiting. Stress-induced nausea is particularly common during anxiety attacks, major life changes, or periods of intense emotional pressure.
