Question

Can nervousness cause stomach upset?

Answer 1

Yes, nervousness can cause stomach upset. When you are nervous and anxious, this sets off the fight or flight response. This fight or flight response shifts the body's resources from the non-essential systems for survival, such as the gastrointestinal system and reproductive system, to the cardiovascular system and skeletal muscles. This shift leads to changes in the gastrointestinal system, such as stomach upset and stomach pain.
