When working out (high cardio) what makes your stomach churn that you want to throw up?

Answer 1

A lot of times that happens because one ate too close to working out..

eating sends ‘build’ signals to the body, while exercise sends ‘breakdown’ signals to the body to produce energy. Those 2 types of signals are opposite to one another

Generally, it’s a good idea to eat 2-3 hours before a workout, anything closer than that could negatively affect exercise performance.
