Asthma causes And Symptoms
Asthma causes: Asthma is a condition where the airways swell and narrow and produce more mucus. This may make breathing difficult and activate coughing, wheezing and shortness of breath.
For many people, asthma is a slight annoyance. For many others, it is sometimes a significant issue that interferes with daily activities and might result in some life threatening asthma attack.
Asthma can’t be cured, but its symptoms can be controlled. Since asthma frequently changes over time, so it is vital that you work with your physician to keep track of your symptoms and signs and adjust treatment as necessary.
Astham causes
It isn’t clear why some people get asthma and others don’t, but it’s probably due to a combination of environmental and genetic (inherited) factors are astham causes.
Asthma causes triggers
Exposure to various irritants and substances that trigger allergies (allergens) can trigger signs and symptoms of asthma. Asthma triggers are different from person to person and can include:
- Strong emotions and stress
- Sulfites and preservatives added to some types of foods and beverages, including shrimp, dried fruit, processed potatoes, beer and wine
- Gastroesophageal reflux disease (GERD), a condition in which stomach acids back up into your throat
- Airborne substances, such as pollen, dust mites, mold spores, pet dander or particles of cockroach waste
- Respiratory infections, such as the common cold
- Physical activity (exercise-induced asthma)
- Cold air
- Air pollutants and irritants, such as smoke
- Certain medications, including beta blockers, aspirin, ibuprofen (Advil, Motrin IB, others) and naproxen (Aleve)
Asthma symptoms differ from person to person. You might have rare asthma attacks, have symptoms only at particular times — like when exercising — or even have signs all of the time.
Asthma signs and symptoms include:
- Asthma signs and symptoms that are more frequent and bothersome
- Increasing difficulty breathing (measurable with a peak flow meter, a device used to check how well your lungs are working)
- The need to use a quick-relief inhaler more often
- Shortness of breath
- Chest tightness or pain
- Trouble sleeping caused by shortness of breath, coughing or wheezing
- A whistling or wheezing sound when exhaling (wheezing is a common sign of asthma in children)
- Coughing or wheezing attacks that are worsened by a respiratory virus, such as a cold or the flu
For some people, asthma causes signs and symptoms flare up in certain situations:
- Exercise-induced asthma, which may be worse when the air is cold and dry
- Occupational asthma, triggered by workplace irritants such as chemical fumes, gases or dust
- Allergy-induced asthma, triggered by airborne substances, such as pollen, mold spores, cockroach waste or particles of skin and dried saliva shed by pets (pet dander)
