What Causes Asthma To Start Up?

Welcome to an insightful article on what causes asthma to start up. Asthma is a common respiratory condition that affects millions of people worldwide. The triggers for asthma can vary from person to person, but common factors such as allergies, respiratory infections, exercise, and environmental irritants can play a role in flare-ups. By understanding these triggers and taking steps to manage them, you can better control your asthma and improve your quality of life. So let’s dive into the factors that could be causing your asthma to start up and how you can effectively manage them.

What Causes Asthma To Start Up?

Have you ever wondered why asthma can suddenly start up out of nowhere? Understanding the triggers and causes of asthma can help you manage the condition better and improve your quality of life. Let’s delve into the various factors that can lead to the onset of asthma.

Genetics and Family History

Did you know that having a family history of asthma puts you at a higher risk of developing the condition yourself? Genetics can play a significant role in the onset of asthma. If one or both of your parents have asthma, you are more likely to have it as well.

Personal Risk Factors

Your own personal health history can also contribute to the development of asthma. If you have had respiratory infections as a child, you may be more susceptible to asthma. Additionally, if you have allergies (such as hay fever or eczema), you are at a higher risk of developing asthma.

Environmental Factors

Environmental factors can also trigger the onset of asthma. Exposure to certain substances and pollutants in the environment can lead to the development of asthma, especially in individuals who are genetically predisposed to the condition.

Common Environmental Triggers

  • Allergens: Pollen, pet dander, dust mites, and mold are common allergens that can trigger asthma symptoms. Avoiding exposure to these allergens can help prevent asthma attacks.
  • Tobacco Smoke: Secondhand smoke or exposure to smoke can irritate the airways and trigger asthma symptoms.
  • Air Pollution: High levels of pollution in the air can exacerbate asthma symptoms and increase the risk of developing the condition.
  • Chemical Fumes: Exposure to fumes from cleaning products, paints, and other chemicals can also trigger asthma symptoms in some individuals.

Respiratory Infections

Respiratory infections, such as the flu or a cold, can also be a trigger for asthma. Infections in the respiratory tract can lead to inflammation in the airways, making it harder to breathe and triggering asthma symptoms.

Viral Infections

Viral infections, such as rhinovirus and respiratory syncytial virus (RSV), are common culprits for triggering asthma attacks. It’s essential to take precautions to avoid getting sick, especially during the cold and flu season.

Occupational Exposures

If you work in an environment where you are exposed to certain substances or irritants, you may be at risk of developing occupational asthma. This type of asthma is triggered by exposure to substances in the workplace, such as chemicals, dust, or fumes.

Common Occupational Asthma Triggers

  • Industrial Chemicals: Workers in industries that handle chemicals, such as cleaners, painters, and factory workers, are at risk of developing occupational asthma.
  • Agricultural Dust: Farmers and agricultural workers who are exposed to dust and pesticides are also at risk of developing asthma.
  • Healthcare Workers: Healthcare workers who are exposed to latex, disinfectants, and other substances in clinical settings may develop occupational asthma.

Allergic Reactions

Allergic reactions can play a significant role in triggering asthma symptoms. When your body comes into contact with an allergen that you are sensitive to, it can lead to inflammation in the airways and cause asthma symptoms.

Common Allergens

  • Pollen: Seasonal allergies to pollen from trees, grasses, and weeds can trigger asthma symptoms.
  • Pet Dander: Animal dander from cats, dogs, and other furry animals can also trigger asthma attacks in individuals with pet allergies.
  • Food Allergies: Certain food allergies can also lead to asthma symptoms in some individuals. Common food allergens include nuts, shellfish, and dairy products.

Smoking and Secondhand Smoke

Smoking and exposure to secondhand smoke can have detrimental effects on your respiratory health and can exacerbate asthma symptoms. If you have asthma, it’s crucial to avoid smoking and exposure to smoke to prevent worsening of your condition.

Effects of Smoking on Asthma

  • Inflammation: Smoking can lead to inflammation in the airways, making it harder to breathe and triggering asthma symptoms.
  • Decreased Lung Function: Smoking can decrease lung function over time, making it more challenging to manage asthma symptoms.
  • Worsening Symptoms: Smoking can worsen asthma symptoms and lead to more frequent asthma attacks.

Hormonal Changes

Hormonal changes can also impact asthma symptoms, especially in women. Changes in hormone levels during puberty, menstruation, pregnancy, and menopause can influence asthma symptom severity.

Puberty and Asthma

  • During puberty, hormonal changes can affect lung function and asthma symptoms. Some individuals may experience worsening asthma symptoms during puberty, while others may see an improvement.
  • It’s essential to work closely with your healthcare provider to manage asthma symptoms during puberty to ensure optimal lung function.

Stress and Emotional Factors

Stress and emotional factors can trigger asthma symptoms in some individuals. Emotional stress can lead to physical symptoms, including shortness of breath and chest tightness, making asthma worse.

Managing Stress

  • Relaxation Techniques: Practices such as deep breathing, meditation, and yoga can help reduce stress levels and improve asthma symptoms.
  • Exercise: Regular exercise can help manage stress and improve overall lung function, reducing the risk of asthma attacks.
  • Therapy: Cognitive-behavioral therapy (CBT) and counseling can be beneficial in managing stress and emotional factors that contribute to asthma symptoms.

Obesity and Asthma

Obesity is a significant risk factor for developing asthma and can worsen symptoms in individuals who already have the condition. The extra weight can put added pressure on the lungs, making it harder to breathe.

Effects of Obesity on Asthma

  • Inflammation: Obesity can lead to chronic inflammation in the body, exacerbating asthma symptoms and making it harder to manage the condition.
  • Reduced Lung Function: Excess weight can restrict lung function, making it more challenging to breathe and increasing the risk of asthma attacks.
  • Treatment Challenges: Obesity can make it more difficult to manage asthma symptoms and may require personalized treatment plans for optimal control.


Understanding the various factors that can trigger asthma symptoms and lead to the onset of the condition is essential for effectively managing asthma. By identifying your personal triggers and working with your healthcare provider to develop a comprehensive treatment plan, you can control asthma symptoms and improve your quality of life. Remember to prioritize your respiratory health and take proactive steps to manage your asthma effectively.
