What causes dry heaving and gastric reflux?

　　Dry heaving and nausea may be associated with factors such as vigorous physical activity, dry air, smoking, overeating, and others. They may also stem from gastric disorders or upper respiratory tract infections. Additionally, psychological factors—such as exposure to adverse stimuli—can trigger reflexive dry heaving and nausea.

　　What Causes Dry Heaving and Nausea?

　　Dry heaving and nausea may arise from various physiological or pathological factors; thus, a precise diagnosis requires individualized assessment based on the patient’s specific clinical presentation. Physiologically, potential triggers include intense exercise, dry ambient air, smoking, and binge eating. These factors may irritate the sensitive nerves in the pharynx and stomach, thereby inducing dry heaving and nausea.

　　Pathologically, dry heaving and nausea may result from improper diet, common colds, early pregnancy, medication use, chronic pharyngitis, or upper gastrointestinal diseases. Acute onset of dry heaving and nausea is often attributable to dietary indiscretion. Patients should pay attention to their eating habits and avoid exposure to cold. In women of childbearing age, early pregnancy must be ruled out by reviewing menstrual history. Medications—including antibiotics or nonsteroidal anti-inflammatory drugs (NSAIDs)—may also provoke these symptoms. Discontinuation of such medications should occur only under physician supervision, after which symptoms may gradually subside.

　　Patients are generally advised to consume moderate amounts of easily digestible foods—such as millet porridge, noodles, or egg drop soup—which provide essential nutrition while minimizing gastric irritation and helping alleviate nausea and dry heaving. Under medical guidance, patients may take medications including domperidone tablets, Xiangsha Yangwei Pills, or omeprazole enteric-coated tablets—agents that support gastric health and suppress nausea/vomiting.
