What’s asthma? its types, signs, causes, and treatment.

Asthma is a disease that affects your lungs’ airways. It is a chronic (ongoing) condition. A chronic condition doesn’t go away and needs ongoing medical management.

Asthma affects more than 24 million people in the United States. This total includes roughly 5.5 million children. Asthma can be life-threatening if you don’t get treatment.

How does asthma work?

Asthma is a chronic respiratory condition where the airways in the lungs are inflamed and narrowed causing breathlessness, wheezing, chest tightness, and coughing. Symptoms come as recurrent episodes known as asthmatic attacks most commonly at night or early in the morning. Asthma is usually diagnosed in childhood and lasts for life.

The lungs contain millions of air tubes or airways, called bronchi and bronchioles, which bring air in and out of the body. The airways have a layer of smooth muscle in their wall which enables them to constrict or dilate. In response to the body's higher demand for air, such as during exercises, the airways dilate to increase airflow.

In the presence of pollutants in the air, the airways constrict to prevent the lungs from being polluted. In people suffering from asthma, these airways are inflamed, narrowed, and become more sensitive to certain substances.

What’s an asthma attack?

When you breathe normally, muscles around your airways are relaxed, letting air move easily. During an asthma attack, three things can happen:

Bronchospasm: The muscles around the airways constrict (tighten). When they tighten, it makes the airways narrow. Air cannot flow freely through constricted airways.

Inflammation: The airway linings become swollen. Swollen airways don’t let as much air in or out of the lungs.

Mucus production: During the attack, your body creates more mucus. This thick mucus clogs airways.

Causes of asthma are complex and not fully understood but likely involve a combination of genetic and environmental factors. Family history is a known risk factor for asthma. There are at least over twenty genes associated with asthma of which many are involved. worldwide suffer from asthma. And about 250,000 people die from it every year.infomationzon.blogspot.com

Why do people get asthma and how can this disease be fatal?

Asthma affects the respiratory system, particularly the smaller airways, such as the bronchi and bronchioles. These airways have an inner lining called the mucosa that's surrounded by a layer of smooth muscle. In people with asthma, the airways are chronically inflamed, which can make them hyper-responsive to certain triggers.

Asthma signs :

Shortness of breath.
Chest tightness or pain.
Wheezing when exhaling, which is a common sign of asthma in children.
Trouble sleeping caused by shortness of breath, coughing, or wheezing.
Coughing or wheezing attacks are worsened by a respiratory virus, such as a cold or the flu.

cause of schema

Tobacco Smoke.
Dust Mites.
Outdoor Air Pollution.
Pests (e.g., cockroaches, mice)
Pets.
Mold.
Cleaning and Disinfection.
Other Triggers.

3 types of asthma

Allergic asthma.
Non-allergic asthma.
Cough-variant asthma.

Allergic asthma.

Allergic asthma is a breathing condition where the airways you breathe through tighten when you inhale an allergen. Common allergens include pollen, dander, and mold spores. This type of asthma is very common in both children and adults.

Non-allergic asthma.

Non-allergic asthma, or non-atopic asthma, is a type of asthma that isn't related to an allergy trigger like pollen or dust and is less common than allergic asthma. The causes are not well understood, but it often develops later in life and can be more severe.

Cough-variant asthma:

Cough-variant asthma is a type of asthma in which the main symptom is a dry, non-productive cough. (A non-productive cough does not expel any mucus from the respiratory tract.) People with cough-variant asthma often have no other "classic" asthma symptoms, such as wheezing or shortness of breath.

first-line treatment for asthma:

Beta-agonists are considered first-line therapy for intermittent asthmatics. If frequent use of beta-agonists occurs more than twice a week, controller therapy should be considered. For persistent asthma, low-dose inhaled corticosteroids are recommended in addition to reliever medication.

The best asthma treatment:

Quick-relief inhalers (bronchodilators) quickly open swollen airways that are limiting breathing. In some cases, allergy medications are necessary. Long-term asthma control medications, generally taken daily, are the cornerstone of asthma treatment.

Foods To Avoid With Asthma:

Eggs.
Cow's milk.
Peanuts.
Soy.
Wheat.
Fish.
Shrimp and other shellfish.
Tree nuts.

The best food for Asthma:

Almonds, hazelnuts, and raw seeds are good sources, as well as cruciferous vegetables like broccoli and kale. Vitamin E has tocopherol, a chemical that could help cut how much you cough and wheeze from your asthma.
