<s>[INST] i had asthama which is said to cause till some age and after that it must disappear but still after eating ice cream or due to dust, paint , and coagulation of phlegm i get hard breathing my age is 19. Please do suggest any necessary care & medicines. [/INST] Hello. Thank you for asking at Chat Doctor. If you have breathing problems only infrequently, I would suggest you to have a albuterol inhaler with you and use it whenever you get symptoms of asthma attack. This is known as intermittent asthma, you need not take regular medications for that. However, if you have frequent symptoms, if your symptoms prevent you from daily activities/exercise/sports, if you have to awaken at night frequently due to cough, you could have persistent asthma. In that case I would suggest you to take regular asthma controller medications. I would suggest you to consult an Allergist-Immunologist who will ask your symptoms in detail and may suggest you allergy testing, which will be helpful to you to decide what to avoid and how to. As general measures, I would suggest you to avoids dusts-air pollution-smokes-cold air currents as much as possible. Please also avoid cold Chat Doctor.  Regular breathing exercises and a nutritive diet rich in vitamins and minerals will help you in long run. Hope this will be helpful to you. Wish you the best of the health. Regards. </s>
