Asthma

There are two types of asthma:

Allergic, which is triggered by allergens, such as animal dander, mold, chemicals, feathers, fumes and tobacco smoke.

Non-Allergic, which can be triggered by temperature changes, anxiety, fear, laughing, stress and low-blood sugar.

Asthma can be difficult to diagnose because it masquerades as other diseases, like bronchitis, emphysema and lower respiratory infections. Blood tests, chest x-rays and other tests are necessary when asthma is suspected.

Possible Causes of Asthma
Asthma is caused by the spasms in the smooth muscles surrounding the bronchi and bronchioles (small airways in the lungs), causing the passageways to partially close. The spasms are accompanied with increased mucus which clogs the bronchioles/bronchi and worsens the attack. It is often triggered by an allergic response and the immune system produces histamine; thus, any type of allergen can precipitate an asthma attack. Cardiac asthma, a less common form of asthma, is caused by heart failure.

Possible Symptoms and Complications of Asthma
Symptoms of asthma include difficulty breathing (especially exhalation), sudden fits of coughing, wheezing and tightness in the chest.  Complications of asthma include home confinement, breathing difficulty, hospitalization, asphyxia, and in very serious cases, death.

Possible Lifestyle Changes for Asthma
Eat a diet high in vegetables, fruits, whole grains, nuts and protein. Avoid ice cream and other cold foods and drinks. Exercise regularly, but moderately if increased activity tends to increase asthma attacks. Find ways to decrease stress and anxiety to help ward off attacks. Consider removing carpeting to remove dust mites, germs and bacteria that can trigger asthma attacks. Cover mattresses and pillows with plastic casings to keep them clean and dust-free.
