Hello, Thank you for asking at HCM. I went through your history and would like to make suggestions for you as follows: 1. As you have shortness of breath, hay fever, initially seasonal progressing to perennial, all these symptoms suggest possibility of asthma, may be allergic. 2. For confirmation of diagnosis of asthma a test known as Spirometry with post-bronchodilator reversibility is necessary. 3. At present, based on your history, I would suggest you allergy testing for common air-born allergens such as house dust mite, insect proteins, molds, pollens, animal dander, etc. This will help you identify the substance causing allergies to you as well as to know the measures to avoid them. Based on allergy testing, an Allergist-Immunologist also may prescribe you allergen specific immunotherapy which works on immune system to gradually improve allergy symptoms over a long time period. 4. As you have symptoms year around, I usually suggest my such patients regular montelukast + levocetirizine and a preventer inhaler such as inhaled corticosteroids. These should to be taken regularly under physician s guidance to avoid symptoms of asthma. 5. For patients with ectopic heartbeats or other heart problems, I usually suggest them to use levosalbutamol in place of salbutamol as levosalbutamol is more safe in terms of cardiac symptoms. Also, regular use of inhaled corticosteroids will reduce your requirement of salbutamol/levosalbutamol. Please note that both salbutamol and levosalbutamol are rescue type of inhalers which are to be used on as-and-when-needed basis. Inhaled corticosteroids are preventer type of inhalers which are to be taken on regular basis. 6. Regular breathing exercises will help you in a long run to improve your lung capacity. 7. A healthy diet rich in vitamins, minerals and antioxidants will also help gradually to improve your immune system. Please note that allergy is a disorder of immune system. Such diet with adequate fluids during day will also improve your symptoms of tiredness. 8. In general, please avoid exposure to dusts, smokes and air pollution as much as possible. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health ahead. Thank you & Regards.
