What happens if you leave an asthma attack untreated?

Asthma is a chronic respiratory condition that affects millions of people worldwide. It is characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, coughing, and shortness of breath. While asthma attacks can be managed and controlled with proper treatment, leaving an asthma attack untreated can have serious consequences for your health. In this article, we will explore the potential risks and long-term effects of untreated asthma attacks.

Consequences of Leaving an Asthma Attack Untreated

When an asthma attack occurs, the airways become inflamed and swollen, making it difficult for air to flow through. If not promptly treated, the following consequences may occur:

Increased Severity of Symptoms

The primary consequence of leaving an asthma attack untreated is the worsening of symptoms. The swelling and inflammation of the airways can lead to:

  • Difficulty breathing and shortness of breath: As the airways narrow, it becomes harder to take in enough oxygen, resulting in a sensation of breathlessness.
  • Wheezing and coughing: The restricted airflow causes a characteristic wheezing sound and persistent coughing.

These symptoms can be not only uncomfortable but also alarming, and they may cause anxiety and distress for the individual experiencing them.

Prolonged Duration of the Attack

Untreated asthma attacks can also result in a longer duration of the attack itself. Delaying treatment can lead to prolonged symptoms, delayed recovery, and frequent exacerbations. This may require more intensive treatments and a longer time to regain normal respiratory function.

Risk of Complications

Leaving an asthma attack untreated increases the risk of complications, including:

  • Respiratory infections: The compromised airways are more susceptible to respiratory infections such as bronchitis or pneumonia.
  • Pneumonia: The inflammation in the airways can facilitate the infiltration of bacteria, leading to the development of pneumonia.
  • Allergic reactions: Asthma attacks can be triggered by allergens, and leaving them untreated may result in more severe and frequent allergic reactions.
  • Respiratory failure: In severe cases, untreated asthma attacks can lead to respiratory failure, where the lungs are unable to provide sufficient oxygen to the body.

Long-Term Effects of Untreated Asthma

Aside from the immediate consequences, untreated asthma attacks can also have long-term effects on your respiratory health. Some of these effects include:

Airway Remodeling

Untreated or poorly controlled asthma can result in changes to the structure of the airways. The persistent inflammation and repeated episodes of swelling can lead to airway remodeling, which refers to structural changes in the airways. These changes can cause a permanent narrowing of the airways, making it difficult for air to flow in and out of the lungs.

Reduced Lung Function

Untreated asthma can also lead to decreased lung function over time. The ongoing inflammation and damage to the airways can result in decreased lung capacity. This means that your lungs may not be able to hold as much air as they should, making it harder to breathe efficiently. Reduced lung function can have a significant impact on your everyday activities and overall quality of life.

Increased Risk of Asthma-Related Mortality

One of the most concerning long-term effects of untreated asthma is an increased risk of asthma-related mortality. When asthma attacks are left untreated or poorly controlled, the frequency and severity of attacks tend to increase. This puts individuals at a higher risk of experiencing severe asthma attacks that can be life-threatening. Prompt treatment and proper management are essential for reducing the risk of fatal outcomes.

Importance of Early Intervention and Treatment

To prevent the potential complications and long-term effects of untreated asthma attacks, it is crucial to seek early intervention and prompt treatment. Here are some important measures to take:

Management with Medications

There are various medications available for managing asthma. Quick-relief medications, also known as bronchodilators, can help to relax and open up the airways during an attack. Long-term control medications, such as corticosteroids, can help to reduce inflammation and prevent future attacks. It is important to work with a healthcare provider to determine the most appropriate medications and dosage for your specific needs.

Asthma Action Plan

An asthma action plan is a personalized guide that outlines the steps to take for asthma management. It typically includes information on recognizing early symptoms, taking appropriate medications, and seeking emergency care if necessary. Following an asthma action plan can help you respond effectively to asthma attacks and prevent complications.

Regular Follow-Up with Healthcare Provider

Regular follow-up appointments with a healthcare provider are essential for monitoring asthma control and adjusting the treatment plan as needed. Your healthcare provider can assess your symptoms, review medication effectiveness, and make any necessary adjustments to optimize your asthma management.


Leaving an asthma attack untreated can have serious consequences for both your immediate and long-term health. It can lead to increased severity and duration of symptoms, as well as an elevated risk of complications. Untreated asthma attacks can also result in permanent structural changes to the airways, reduced lung function, and a higher risk of asthma-related mortality. Prompt treatment and regular asthma management are crucial for mitigating these risks and maintaining optimal respiratory health. If you have asthma, it is important to work closely with your healthcare provider to develop an individualized treatment plan and take the necessary steps to manage your condition effectively.
