Asthma is a long-term disease of the lungs. Its causes airways to get inflamed and narrow, and it also makes it hard to breathe. Severe asthma can cause trouble in talking.  Asthma also refers as “bronchial asthma.”.  It is inflammation of the bronchial tubes; this inflammation is due to extra sticky secretions inside these tubes. People with asthma have symptoms when the airways tight, inflame, or fill with mucus.

Three major signs:

  • Airway blockage. When you breathe as usually, muscle bands around your airways are relaxed, and air moves freely. But when you have asthma, the muscles tighten. It’s harder for air to pass through.
  • Inflammation. It causes red and swollen bronchial tubes in lungs. This inflammation can damage your lungs.
  • Airway irritability.  With asthma People have sensitive airways. These airways tend to overreact and narrow when they come into contact with triggers.

Childhood asthma

It is the most common condition in children. It can develop at any stage of age, but it is slightly more common in children than in adults. Some common factors of childhood asthma include:

  • respiratory infections and colds
  • cigarette smoke, including secondhand tobacco smoke
  • allergens
  • air pollutants, including ozone and particle pollution, indoors and outside
  • exposure to cold air
  • sudden changes in temperature
  • excitement
  • stress
  • exercise

Adult-onset asthma

It can develop at any age; adults are more likely than children to have persistent symptoms.

Some factors that increase the risk of developing asthma in adulthood include:

  • respiratory illness
  • allergies and exposure to allergens
  • hormonal factors
  • obesity
  • stress
  • smoking

Occupational asthma

Occupational asthma can spread from exposure to an allergen or irritant present in the workplace. In these workplaces, allergens cause it in those with a sensitivity or allergy:

  • bakeries, flour mills, and kitchens
  • hospitals and other healthcare settings
  • pet shops, zoos, and other laboratories where animals are present
  • farms and other agricultural settings

In these occupations, irritants can trigger its symptoms:

  • car repairs and manufacturing
  • engineering and metalwork
  • woodwork and carpentry
  • electronics and assembly industries
  • hairdressing salons
  • indoor swimming pools

Those with a higher risk include people who:

  • smoke
  • have allergic rhinitis
  • have a history of asthma or environmental allergies
Seasonal asthma

Seasonal asthma occurs in response to allergens that are present in the surrounding environment at certain times of year. For example, cold air in the winter or pollen in the spring or summer trigger symptoms of seasonal. People with seasonal asthma still have this condition for the rest of the year, but they usually do not experience any symptoms.


Asthma symptoms vary from person to person. You may have infrequent asthma attacks, have symptoms only at certain times — such as when exercising — or have symptoms all the time.

  • Wheezing, a whistling sound when you breathe
  • Shortness of breath
  • Tightness, pain, or pressure in your chest
  • Trouble sleeping because of breathing problems
  • Increasing difficulty breathing, as measured with a device that is used to check how well your lungs are working (peak flow meter)

Causes and triggers

Health professionals do not know exactly about the causes of asthma, but genetic and environmental factors both play significant roles.

list of some others causes.


smoking during pregnancy increase the risk of the fetus developing this condition of asthma later in their life. Some women also experience of asthma symptoms while pregnant.


Higher levels of asthma in people with obesity than those without it.


Allergies can develop when a person’s body becomes sensitized to a specific substance. Once the sensitization has taken place, the person will be susceptible to an allergic reaction each time they come into contact with that substance. Not every person with it has an allergy, but there is often a link between allergy and it.

 Smoking tobacco

  • ground-level ozone


Stress can also start symptoms, but several other emotions such as Joy, anger, excitement, laughter, crying, and other emotional reactions can also trigger an attack.

 Some genetic changes that may play a role in its development. In some cases, epigenetic changes are responsible. These can occur when an environmental factor causes a gene to change.
