What causes chest tightness and dry vomiting?

　　In fact, recurrent chest tightness manifests with a variety of symptoms. Some individuals may experience no noticeable discomfort—suggesting the condition is relatively mild. Others, however, may feel extremely uncomfortable, as if something heavy is constantly pressing on their chest, accompanied by shortness of breath. Such symptoms often indicate an underlying medical condition, and prompt evaluation and treatment are generally recommended.

　　What Causes Chest Tightness Accompanied by Dry Heaving?

　　When chest tightness occurs together with vomiting (including dry heaving), myocardial ischemia should be considered first—particularly inferior wall myocardial ischemia, which is more common in such presentations. Diagnosis can be confirmed via electrocardiogram (ECG) and cardiac enzyme testing upon symptom onset. Gastrointestinal disorders—including gastritis or gastric/duodenal ulcers—may also cause chest tightness and vomiting, primarily through gastroesophageal reflux or esophageal spasm. Additionally, psychological conditions—such as functional (neurogenic) vomiting—can produce similar symptoms. Therefore, when encountering patients presenting with chest tightness and vomiting in clinical practice, thorough diagnostic evaluation is essential to identify the underlying cause, followed by targeted treatment.

　　If chest tightness is accompanied by dizziness, reduced coronary blood supply is often suspected. Referral to a cardiology department is advised, with ECG used to confirm diagnosis. Dietary management typically emphasizes low-fat foods. If dizziness is also associated with cervical spondylosis or cerebral hypoperfusion, patients should avoid prolonged periods of forward head posture during work or study.

　　Patients are advised to maintain a balanced diet rich in nutrients, fresh fruits, and vegetables, and to engage in moderate physical exercise. We hope this information proves helpful.
