In people with asthma, the inside of the airways can get red, swollen, and filled with mucus. In people with asthma, the muscles around the airways can spasm and squeeze tighter. This leaves less room for air to pass through.
The airways close up so exhaling becomes difficult. Symptoms: intermittent sob, cough, wheezing, chest tightness. Usually worse at night and/or early a.m. Chest tightness from the airways closing up: band-like constriction.
Each person with asthma has her own set of asthma inducers and asthma triggers. Asthma inducers: If you breathe in something you're allergic to- for example, dust or pollen- or if you have a viral infection- for example, a cold or the flu- your airways can become inflamed (red and swollen). Asthma triggers: If you breathe in an asthma trigger like cold air or smoke, or if you exercise, the muscles around your airways can go into spasm and squeeze together tightly. This leaves less room for air to pass through.
It's important for every person with asthma to know what their triggers and inducers are, so they can avoid them.
