Is Asthma Genetic? | Risk factors of Asthma

Does Asthma run in the family?

Asthma may be genetic; however, not all instances of asthma are genetically inherited. Asthma is a spectrum of reasons as well as risk factors.

Asthma is a lung disease that can cause inflammation within the airways. Inflammation may cause the airways in the lungs to swell and become extremely sensitive, causing the chest to tighten and wheeze.

Asthma is a problem for people of all different ages and genders. It is estimated that in the United States, 8%Trusted Source of adults has asthma. But, certain people could be more susceptible to developing asthma than others.

This article examines whether the different forms of asthma are linked to genetics, other causes and risk factors, and treatment.

Are the different kinds of asthma genetic?

Many types of asthma are genetically based. The various kinds that suffer from asthma include:

  • Adult-onset asthma that develops in adults
  • Exercise-induced asthma
  • allergic asthma
  • Nonallergic asthma
  • occupational asthma
  • asthma and chronic obstructive pulmonary disorder

One has a higher chance to suffer from asthma when one has an ancestral history of the disease. As such, asthma could be inherited. Researchers have described asthma as being a “highly inheritable disease.”

According to a 2014 study by the Trusted Source, Genetic factors are responsible for about 70% of an individual’s chance of being diagnosed with asthma. This means that genes significantly influence whether or not a person develops the disease.

But, genetics isn’t the sole reason for asthma. People develop asthma even when they do not have a relative with the disease. One could have a genetic predisposition to asthma but not suffer from it.

Genetics play a less significant influence on the development of asthma later in life, which means the onset of asthma in adults and occupational asthma is not as dependent on genetics.

One can also suffer from asthma without a genetic predisposition or genetic cause for the disease. Indeed, many external factors can cause asthma in a person.

What causes asthma?

Both environmental and genetic factors are both involved when it comes to the making of asthma. However, scientists don’t know the precise causes. They have discovered several triggers for asthma-related symptoms.

The asthma triggers can differ from individual to individual and could include:

  • respiratory infections, such as flu or cold the flu
  • Airborne irritants
  • air pollution
  • Smoke from tobacco
  • exercise
  • cold air
  • Medicines, like beta-blockers as well as nonsteroidal anti-inflammatory medicines
  • stress
  • Preservatives for food and drinks
  • allergens like dust, dander, and pollen

Risk factors

Specific factors that increase the risk of developing asthma can increase the likelihood of becoming asthmatic.

Genetics or family background of asthma can increase the chance of developing asthma at an early stage in their lives.

Other potential risk factors for asthma comprise:

  • being overweight
  • smoking
  • who suffer from allergies or other Allergies
  • often exposed to second hand smoke
  • exposure to different types of pollution, like exhaust emissions
  • Exposure to occupational-related irritants, which include dust and chemicals


Asthma symptoms and severity differ by individual. Certain people might often experience symptoms, whereas others may have them occasionally.

Asthma symptoms may be characterized as:

  • wheezing
  • chest tightness
  • difficulties breathing
  • breathlessness
  • coughing

Sometimes, triggers may trigger a short-term worsening of asthma attacks if someone is suffering from an asthma attack, the bronchial tubes of their body contract.

In the course of an asthma attack, asthma symptoms can get severe, and you may require an emergency inhaler or, in certain instances, emergency medical treatment.

Asthma symptoms are:

  • A sensation of the chest tightening rapidly
  • rapid breathing
  • blue-tinted nail and skin
  • breathlessness that isn’t related to physical exercise
  • chest retractions
  • the inability to breathe the full breath

Many people have asthma. Not all suffer from all of these symptoms. Additionally, the fact that someone exhibits these symptoms does not guarantee that they have asthma.

Treatment for asthma aims to Assist people in managing their symptoms of asthma and avoiding attacks . It could also help reduce the long-term lung damage that can result from uncontrolled asthma .

A physician may suggest an array of treatment options.

Asthma treatment that lasts for a long time may consist of:

  • long-term inhaled asthma medication such as corticosteroids, bronchodilators, and inhalers that combine
  • Allergy medication

Doctors may also prescribe quick-acting short-term asthma medications to treat attacks. They can be:

  • Oral or intravenous steroids reduce the severity of attacks by reducing swelling in the airways.
  • quick-acting bronchodilators, like albuterol inhalers

A physician may also suggest lifestyle adjustments to help people manage their symptoms.

The lifestyle modifications that someone who has asthma may include:

  • Recognizing triggers and staying clear of them
  • Air conditioning is an excellent option to prevent allergens that trigger asthma from outside.
  • regular cleaning of the home to keep away dust and mildew
  • Covering the nose and mouth when it is cold
  • managing stress and intense emotions


Asthma is a genetic disorder; however, it could be caused by other causes or risk factors, particularly in asthma that develops at an adult age.

The majority of people can manage their asthma effectively through medication. However, some people might experience difficulties bringing their asthma symptoms to work.

In such situations, individuals should be aware of their triggers and stay clear of them as frequently as is possible.
