Thanks for your question on Healthcare Magic. I can understand your concern. In my opinion, you should consult pulmonologist for your husband. Her is having chronic GERD (gastroesophageal reflux disease) which is causing bloating, heartburn, chest pain etc. This chronic GERD can cause asthma and breathlessness due to chronic reflux in the lungs. And they will cause shortness breath tiredness etc. So consult pulmonologist and get done clinical examination of respiratory system and PFT (pulmonary function test). PFT will not only diagnose bronchitis but it will also tell you about severity of the disease and treatment is based on severity only. He will need inhaled bronchodilator and inhaled corticosteroids. Control of GERD is also important. So avoid stress and tension, avoid hot and spicy food. Continue prilosec. Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
