Dyspnea: Shortness of breath can be from several causes, heart and lung issues are first, such as asthma, heart failure, etc. It is can also be secondary to stomach problems, such as gastritis and acid reflux. Chronic nasal congestion from allergies can also cause shortness of breath. Anemia is also another cause, the list is endless.

A 21-year-old member asked:

Why do I always get so short of breath after climbing stairs, but not while I am climbing them?

See below: You are more likely to notice the shortness of breath after you stop and maybe that is why you stopped in the first place. Keep walking and you will eventiually get short of breath while doing the exercise. When you stop you have just completed the entire exercise so more likely to be short of breath than when you were halfway finished.

Short of breath: It very well be something in your home you are reacting to. It could be mold, or something you are allergic to e.g. House dust, mites, or some chemical you are reacting to. Animals in the home can also cause allergy and problems with irritattion of the lungs. You could have low grade asthma. You may have a toxic home. You need medical attention to find out why you are short of breath.

A 43-year-old member asked:

If someone with a greenfield filter develops shortness of breath, could there be a clot in the filter?

2 doctor answers2 doctors weighed in
Dr. Aaron Milstone
Pulmonology 27 years experience
Yes: Unfortunately filters may not be all that protective. Filters can actually develop clot on the metal extensions of the device. These can break off and embolize to the lungs. Filters should really never be placed without having the patient also on blood thinner unless the patient absolutely cannot take blood thinner.
