What should I do if I vomit whenever I cough?

  Vomiting upon coughing can be managed through general treatment and medication. Specific approaches are as follows:
　　1. General Treatment
　　If a person has consumed excessive amounts of spicy or irritating foods, or has overeaten, gastric motility may slow down, causing food to remain in the stomach. During coughing, this may lead to abnormal relaxation of the lower esophageal sphincter, resulting in vomiting. Patients can relieve symptoms by engaging in light activities such as slow walking to promote gastrointestinal motility.
　　2. Medication
　　If inflammatory lesions exist in the digestive tract and general treatment is ineffective, medications such as domperidone tablets, omeprazole enteric-coated capsules, or pantoprazole sodium enteric-coated tablets may be used. However, medication must be taken under the guidance of a qualified physician. If any discomfort occurs during treatment, medical attention should be sought promptly.
　　It is recommended that patients maintain a healthy lifestyle during treatment, avoid staying up late, eat a bland diet, and refrain from consuming irritating foods such as spicy, raw, cold, or greasy items. Smoking and alcohol consumption should also be avoided.
