Hi there,
This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.

Yes laryngospasm can occur during vomiting.

Both are mediated by the vagus nerve stimulation.

The nausea results in the activation of the forceful reverse peristalsis of the stomach pushing the content into the esophagus.

The vomiting center then quickly sends signal to the glottis which is closedc due to the strong contractions of the laryngeal muscles to prevent any aspiration to the lungs.

This can sometimes results in laryngospasm causing life threatening situation by affecting air movement into lungs.

But the whole reflex only lasts for seconds hence not usually a problem.

Best wishes,
