What does 'retching' involve?

Attempting to vomit with no outcome
Evacuation of gastric contents
Feeling nauseous
Experiencing abdominal cramping

The correct answer is: Attempting to vomit with no outcome

Retching refers specifically to the involuntary actions involved when a person attempts to vomit, but no stomach contents are expelled. This act is characterized by the rhythmic contraction of the diaphragm and abdominal muscles, which creates the sensation and action associated with vomiting, even if it does not result in the expulsion of gastric contents. Retching is often accompanied by a feeling of discomfort or nausea, but unlike actual vomiting, it does not result in the evacuation of the stomach. Understanding this distinction is essential, as it highlights the process of what happens in the gastrointestinal system during these involuntary actions.
