What is asthma? And why is it classified as an allergic type?
Asthma is caused by two factors:
- First, the contraction of the bronchi (or air ducts into the lungs) obstructs airflow to the lungs.
- Second, because the inner membrane of the bronchi is swollen and secretes mucus leading to bronchial obstruction.
Allergic reactions are one of the causes of these two factors. These factors make patients have difficulty in breathing, chest pain, chronic cough, wheezing.
About 20-25% of people with nasal allergies also have asthma. Conversely, about 20-80% of people with asthma also suffer from allergic rhinitis. There is therefore a relation between the two. However, allergies are not the only cause of asthma. One of the other causes is air pollution.
Symptoms of allergies and asthma
Both allergies and asthma can cause respiratory symptoms, such as coughing and airway congestion. However, there are also symptoms unique to each disease.
Allergies may cause:
- watery and itchy eyes
- sneezing runny nose
- scratchy throat rashes and hives
Asthma usually does not cause those symptoms. Instead, people with asthma more often experience:
- chest tightness
- breathlessness coughing at night or in the early morning
In addition to these symptoms, such as hay fever, asthma and eczema, can any person have any other symptoms?
Allergic reactions can occur anywhere in the body and cause symptoms at the site. For example:
Allergic reactions may occur on one or more parts of the body at the same time; in other words, allergic symptoms can change with time on the same person. For example, a newborn baby may have an allergy to eczema. Eczema make it hard to raise him/her when they grow up. Older people may have neck pain, dry cough, abdominal pain.
Treatment for allergies and asthma
As we all know, all the symptoms of this disease are caused by the body’s exposure to allergens. These allergens then stimulate the body to release chemicals that cause symptoms to the sick. Therefore, the most reasonable way for treatment is to avoid contact with the heteroantity, if possible, by reviewing and changing the environment.
For example, if you are allergic to cats and dogs hairs, stay away from them.
If you have dust allergies, clean the house, use HEPA air purifiers. In the event that all allergic reactions cannot be avoided, medications should be used to prevent allergic reactions and to reduce symptoms.
- For rhinitis, patients can take Antihistamine or Decongestant medication (one or both, depending on whether or not they have a stuffy nose).
- For first generation products like Diphehydramine (Benadryl), patients may have side effects such as drowsiness, difficulty working and unable to drive.
- Second-generation antihistamines such as Loratadine (Claritin), Fexofenadine Hydrochloride (Allegra) which do not cause drowsiness. In addition, your doctor may add topical steroids to the nasal spray. However, all antihistamines and decongestants are used to relieve the symptoms and cannot cure the cause of the disease. To get rid of the root cause may require immunotherapy (or allergy shots).
Consulting with a physician, and taking steps to limit exposure, even people with both asthma and allergies can effectively manage both conditions.
