When we experience anxiety, our body goes into a fight or flight mode. Releasing stress hormones like cortisol and adrenaline. These hormones can affect the digestive system, leading the symptoms like nausea, stomach pain, or even vomiting. Anxiety-induced nausea is a real physiological response, so you're not making it up.

During moments of anxiety, the sympathetic branch becomes overactive, triggering a cascade of psychological responses.
