Asthma is a disease that narrows the airways due to swelling and excess mucus. Patients with asthma usually have difficulty breathing. They may also suffer chest tightness, chronic coughing, and wheezing. While there is no definitive cause for asthma; there are certain common triggers that patients can avoid to reduce the symptoms and frequency of asthma flare ups. Certain foods for example, can worsen symptoms or even cause a severe asthma attack, such as: 1. Eggs Someone who has an allergy to this would break out in hives. If you have asthma, it could be one of your more severe triggers. Severe asthma can cause a rapid increase in your airway inflammation. Asthma attacks are more likely to occur when eating eggs. Or perhaps eating something containing it. 2. Cow’s milk Milk is the root for a good digestion of calcium and sturdy bones. Unfortunately, if you suffer from asthma you may want to keep away from dairy products. The reason is because cow’s milk could produce more mucus in your lungs that is already there. Milk is customary in most foods, which means it is more likely for consumption. Which in turn, makes asthma symptoms worse. 3. Nuts Nuts, particularly tree nuts (i.e., peanuts) are another common trigger for sevre asthma attacks.
