Patient discussion about breathlessness

Q. can one prevent asthma attack from happening from the moment he/she feels breathless???

A. If the patient feels breathless, than it's no longer preventing the attack but rather treating it. Prompt treatment of asthma attacks is very important and achieved mainly with bronchodilators (medications taken through inhalation), mainly short-acting beta agonists. More advanced treatments is usually given by medical professional as deemed needed.

Preventing asthma attacks is achieved through better control of the disease (with drugs such as inhaled steroids) and through avoidance of triggers such as infections of the lung (vaccinations etc.), avoidance of chemical irritants, pet allergens, cold, dry air etc.

Q. Is there a known connection between asthma and cat allergy? I've been with asthma for many years now but usually get several attacks every year and they are caused from being around pine trees or when I'm with a cold- it also affects my breathing. Lately I get serious attacks after being in a house with a cat. I've never knew a cat allergy- I used to pat many and never got breathing difficulties as a result of a touch with them and lately it happends every time. Are cat a known asthma cause? can I do anything to prevent that?Can I maybe overcome it by being next to cats more often and getting myself used to it?

A. you may be becoming more sensitive to cats an other things--there are drugs on the market that you take everyday to control asthma/allergies--that can prevent you from even having an attack--i am a retired respriratory therpist/emt so i dont no about natural/chinese medicines---i will tell you this asthma can kill --donot try to treat yourself--i dont no what kind of dr you have but--go to a pulmonary DR. with asthma you have to take your meds everyday because skipping can cause you to be come more sensitive to allergens an can cause you to go into a bad attack---mrfoot56--feel better.
