Asthma is a condition that makes breathing difficult due to swelling and tightening of the airways.
Your risk of developing asthma depends on how many of these factors are present.

Instead, multiple genes contribute.
Environmental Factors
Several environmental factors can also cause asthma.
For example:
3.
Immune System Sensitivity
An overactive or sensitive immune system can also play a role in developing asthma.
Smoking
Smoking is a significant risk factor for developing or worsening asthma.
Cigarette smoke contains harmful chemicals that irritate the airways, damage lung tissue, and reduce lung function.
Excess Weight
Being overweight is a significant risk factor for asthma.
Fat tissue is also linked to chronic inflammation.
People with excess weight have higher levels of certaininflammatory markersthat can cause airway narrowing and reduced lung function.
Allergies andallergic asthmaare triggered by glitches in the immune system.
The immune system overreacts when exposed to an allergen, like pollen or pet dander.
Why Do Some People Have More Severe Asthma?
You may also find yourself limiting activity to avoid a flare-up or attack.
Severe asthma happens because of extra sensitive lungs, genetics, or other chronic health conditions.
Summary
A combination of genetic, environmental, and lifestyle factors causes asthma.
It can be triggered by various allergens, poor air quality, and weather, among other things.
People with asthma can lead active, healthy lives by following their treatment plans and avoiding triggers.
