What is wretching?

Wretching, also known as dry heaving, is the involuntary spasm of the respiratory and stomach muscles that results in the sound and motion of vomiting, without actually expelling any vomit or gastric contents. It is often a symptom of nausea, stomach discomfort, or other gastrointestinal disorders. Wretching can be triggered by various causes, such as intoxication, food poisoning, motion sickness, morning sickness during pregnancy, or stress and anxiety. It can cause dehydration, fatigue, and abdominal pain if it persists for a long time, and it may also lead to more severe conditions if left untreated. Treatment for wretching may include medication to manage nausea and vomiting, psychological counseling, hydration, and checking for any underlying medical conditions.
