Hello dear
I understand your concern
Acid reflux cause cough and decrease the propulsive movement of the git cause nausea and vomiting after eating.
I would suggest to consult the gatroenterologist and go for endoscopy to rule out severe
esophagitis.
Doctor will give following advises:
Tablet esmoprazole before meal
Syrup mucine
Tablet domperidone
Take soluble fiber like isaphgul husk for proper movement
Avoid spicy/oily food, alcohol and smoking
Take diet like banana, rice, applesauce, yogurt, buttermilk and toast.
Take cough expectorants like
guaifenesin.
For asthma take
Deriphyllin Retard 300 or salbutamol inhaler
Take steam inhalation
Hope this may help you
Contact HCM for the further heath issue
Best regards
Dr. Sagar
