From your symptoms and history it seems to be Gastroesophageal Reflux Disease
(GERD). This may be due to various causes like Z-E Syndrome, Hiatal hernia, obesity. GERD also causes breathing problems. Some investigations like endoscopy
and esophageal pH monitoring are required to confirm the diagnosis.
Avoid eating spicy foods. Medications like Pantoprazole
help in reducing acidity and vomiting.
Surgery may be required depending upon report after investigation. Consult a local gastroenterologist for clinical examination.
