Asthma causes 

What is Asthma

Asthma is a disease that causes to swell and narrow the airways of the lungs, leading to wheezing, dyspnoea, chest tightness, and coughing.

 

Symptoms of Asthma

Most people with asthma have attacks separated by symptom-free periods. Some people have long-term shortness of breath with episodes of increased shortness of breath. Either wheezing or a cough may be the main symptom.

 

Asthma attacks can last for minutes to days, and can become dangerous if the airflow is severely blocked.

 

Symptoms include:

  1. Cough with or without sputum (phlegm) production
  2. Pulling in of the skin between the ribs when breathing (intercostal retractions)
  3. Shortness of breath that gets worse with exercise or activity
  4. Wheezing

 

Emergency symptoms that need prompt medical help:

  • Bluish color to the lips and face;
  • Decreased level of alertness, such as severe drowsiness or confusion, during an asthma attack;
  • Extreme difficulty breathing;
  • Rapid pulse;
  • Severe anxiety due to shortness of breath;
  • Sweating;

 

Other symptoms that may occur:

  • Abnormal breathing pattern –breathing out takes more than twice as long as breathing in–
  • Breathing temporarily stops
  • Chest pain
  • Tightness in the chest

 

Causes of Asthma

Asthma is caused by inflammation (swelling) in the airways. When an asthma attack occurs, the lining of the air passages swells and the muscles become tight surrounding the airways. This reduces the amount of air that can pass through the airway.

 

In persons who have sensitive airways, asthma symptoms can be triggered by breathing in substances called allergens or triggers.

Risk factors of common asthma:

  1. Animals (pet hair or dander)
  2. Dust mites
  3. Certain medicines (aspirin and other NSAIDS)
  4. Changes in weather (most often cold weather)
  5. Chemicals in the air or in food
  6. Mold
  7. Pollen
  8. Respiratory infections, such as the common cold
  9. Strong emotions (stress)
  10. Tobacco smoke

 

Many people with asthma have a personal or family history of allergies, such as hay fever (allergic rhinitis) or eczema.

Others have no history of allergies.

 

Treatment of Asthma

The goals of treatment are:

= Control airway swelling

= Stay away from substances that trigger your symptoms

= Help you to be able to do normal activities without asthma symptoms

 

You and your doctor should work as a team to manage your asthma. Follow your doctor’s instructions on taking medicines, eliminating asthma triggers, and monitoring symptoms.

 

Medicines Treatment for Asthma

There are two kinds of medicines for treating asthma:

  1. Control medicines to help prevent attacks
  2. Quick-relief (rescue) medicines for use during attacks
  3. Long-term Medicines

 

These are also called maintenance or controller medicines. They are used to prevent symptoms in people with moderate to severe asthma. You must take them every day for them to work. Take them even when you feel OK.

 

Some long-term medicines are breathed in (inhaled), such as steroids and long-acting beta-agonists. Others are taken by mouth (oral). Your doctor will prescribe the right medicine for you.

 

Quick-relief Medicines

These are also called rescue medicines. They are taken for:

Coughing,

Wheezing,

Trouble breathing,

Or an asthma attack.

 

Just before exercising to help prevent asthma symptoms caused by exercise.

Tell your doctor if you are using quick-relief medicines twice a week or more. Your asthma may not be under control and your doctor may need to change your dose of daily control drugs.

 

Quick-relief medicines include:

Short-acting inhaled bronchodilators

Oral corticosteroids for when you have an asthma attack that is not going away

 

A severe asthma attack requires a checkup by a doctor. You may also need a hospital stay. There, you will likely be given oxygen, breathing assistance, and medications given through a vein (IV).

 

Prevention

You can reduce asthma symptoms by avoiding triggers and substances that irritate the airways.

  • Cover bedding with allergy-proof casings to reduce exposure to dust mites.
  • Remove carpets from bedrooms and vacuum regularly.
  • Use only unscented detergents and cleaning materials in the home.
  • Keep humidity levels low and fix leaks to reduce the growth of organisms such as mold.
  • Keep the house clean and keep food in containers and out of bedrooms. This helps reduce the possibility of cockroaches. Body parts and droppings from cockroaches can trigger asthma attacks in some people.
  • If a person is allergic to an animal that cannot be removed from the home, the animal should be kept out of the bedroom. Place filtering material over the heating outlets to trap animal dander. Change the filter in furnaces and air conditioners often.
  • Eliminate tobacco smoke from the home. This is the single most important thing a family can do to help someone with asthma. Smoking outside the house is not enough. Family members and visitors who smoke outside carry smoke residue inside on their clothes and hair. This can trigger asthma symptoms. If you smoke, now is a good time to quit.
  • Avoid air pollution, industrial dust, and irritating fumes as much as possible.
