Asthma is a chronic infection of the lungs that affects the entire airway from your nose till lungs. It causes wheezing and can make it tough to respire normally. Some asthma episodes are triggered due to an allergen or irritant, viruses, exercising, emotional strain, and other factors.

Asthma irritates the internal walls of the airlines, or a bronchial tubes, and causes them to become swollen and infected. During an asthma or allergy attack, the airways will swell, the muscle tissue round them will tighten, and it will become tough for air to move inside and out from the lungs.

For a few human beings, bronchial asthma is a small problem but for some it can affect the quality of life, create problems with everyday activities and become life-threatening.

Asthma Causes

Inflammation of the lungs or asthma occurs when a physical component such as allergens, pollens, viruses or other micro agents attack on immune system.

Acute asthma

Acute infection can be the end result of:

  • Exposure to an irritant, together with a dust or bee bite
  • any type of internal wounds
  • an inflammation

When a human body finds any pathogens or damage, immune system results in a different kind of reactions:

  • Plasma proteins accumulate at the damaged tissue site, which results in infection because of the buildup of fluid at the site of damage.
  • Neutrophils releases from white blood cells or leukocyte, they get closer to the affected vicinity. Molecules that fight with pathogen, are also released from these leukocytes to the site of infection.
  • Leukocytes and plasma proteins reach the site of injury with the help of enlargement of small blood vessels.

Acute inflammation signs can be troublesome and occur simultaneously. In some cases, they can become life threatening as well. How severe and how long they’ll stay will rely upon the extent of injury to the tissues or exposure to the irritant.

Chronic asthma

Chronic asthma infection can expand if a person’s body has:

Sensitivity: Chronic inflammation can happen when immune system triggers something irrelevant in a body. Super sensitivity to an outside entity can bring about an allergic reaction.

Exposure: Sometimes, lengthy-time period, low-grade exposure to an irritant, consisting of a commercial chemical, can bring about such long-term infections.

Autoimmune disorders: Immune system sometimes mistakenly attacks normal tissue, which results in the form of long-term asthma infection.

Auto inflammatory diseases:  In auto inflammatory disease, inherited elements can trigger the immune system to attack airways or cells of airways causing long term asthma.

Persistent acute inflammation: In few instances, when acute inflammation is not well treated completely, so this may result in chronic infection.

Factors that could increase the hazard of chronic infection includes:

  • Old age
  • Being obese or unhealthily fat
  • Diet with unhealthy fats and ultra-processed sugar
  • Cigarettes and tobacco smoking
  • Hormonal fluctuations
  • Pressure on the lungs, or general depression/stress
  • Sleep troubles

In healing, inflammation play an important role however, chronic infection may additionally increase the threat of numerous diseases, such as rheumatoid arthritis, some of cancers, atherosclerosis, hay fever and periodontitis. (1,2)

Asthma Symptoms

The symptoms of asthma depend on a person’s body. Person may additionally have uncommon hypersensitive reactions or attacks sometimes with exercise, daily routine activities, stress and more. Asthma symptoms and signs are:

  • Problem in breathing
  • Tightness of chest
  • Reduced lung capacity.
  • Wheezing when exhaling, that’s a common signal of allergies in children
  • Trouble napping resulting from problem in breathing
  • Coughing attacks which can be worsened through a breathing virus, along with flu or a cold.

For some human beings, allergies symptom and sign can contribute to the asthma attacks.

  • Exercise-induced allergies, which can be worse when air is dry and boldness.
  • Occupational bronchial asthma, precipitated by inhaling workplace irritants which include dirt, gases or chemical particles.
  • Allergy-prompted attacks, brought about through airborne substances, including mold spores, pollen, waste of cockroach, skin particles and dander of pets.

Asthma Triggers

Exposure to various irritants and materials that cause allergies (allergens) can trigger symptoms of asthma. Asthma triggers are specific from person to person and may encompass:

  • Airborne allergens, such as dust particles, pollen, mold spores, debris of cockroach or pet dander
  • Respiratory tract infections, including habitual bleeding
  • Physical activity
  • Cold wind
  • Air pollution, irritants and smoke
  • Certain Some drugs, including aspirin, beta blockers and non-steroidal anti-inflammatory drugs including ibuprofen (Motrin IB, Advil, etc.) and naproxen sodium (Aleve)
  • High sensation and stress,
  • Sulfites and preservatives are added to some foods and beverages, such as shrimp, nuts, processed potatoes, beer, and wine.
  • (GERD) Gastroesophageal reflux disease, a condition in which acid flows from the stomach to the throat.

Asthma medicines and treatments

There are 4 varieties of bronchial asthma drugs and treatments:

  • Quick-relief drugs – These drug treatments work quickly to alleviate sudden and acute signs and symptoms. User takes them as per need.
  • Controller drugs – These drugs assist in manipulating bronchial asthma via correcting the underlying problems in the airways, which include swelling and extra mucus. They may be one or aggregate of drugs.
  • Combination of quick-alleviation and controller drugs – These drug treatments are used for each quick-relief remedy and management of asthma in long-term. (They are used in long-acting-inhalers, however, their use is no longer allowed approved by FDA).
  • Biologics – This type of treatment targets a protein to prevent swelling inside the airlines. They are for humans with positive kinds of persistent bronchial asthma and are given by using injection or infusion. (1,2)
