What are Silent Asthma Attacks?

The term “silent asthma” is not well defined. It’s not a diagnostic phrase, and some medical practitioners may use it haphazardly to refer to asthma with a quiet symptom. Asthma symptoms that are quiet are referred to as silent symptoms. Coughing and wheezing would not be included in this category. Breathlessness and chest tightness are the most typical silent signs of asthma. Nevertheless, a diagnosis of asthma based solely on these two symptoms is uncommon. When an asthma attack occurs without any of the typical audible signs, it is referred to as having silent asthma symptoms. The sounds of wheezing, gasping, or coughing are audible signs. 

Why are silent asthma attacks so dangerous?

Your breathing may get more difficult and your wheezing may become louder if you don’t take your asthma medication and get treatment very away. Using a peak flow meter during an asthma attack will likely result in a reading that is below optimal.

You might not be able to use the peak flow meter at all as your lungs continue to constrict during the asthma episode. Your lungs may gradually become so constricted during an asthma episode that there is insufficient airflow to cause wheezing. This warning sign, sometimes known as the “silent chest,” should be taken seriously. If you are having a serious asthma attack, you need to be brought right away to the hospital.

If you don’t get the right care for an asthma attack, you can eventually lose your ability to speak and your lips might start to turn blue. You are experiencing “cyanosis,” a colour change that indicates decreasing blood oxygen levels. You could lose consciousness and possibly pass away if you don’t receive urgent treatment right away in an emergency room or critical care unit.

Asthma patients have a wide range of therapy options. To effectively manage symptoms, early intervention, prevention, and therapy are essential. 

Similar to asthma with wheezing, quiet asthma can be treated primarily with drugs that lessen or eliminate symptoms. The ideal course of therapy will be decided in consultation with your doctor and tailored to your particular case of asthma.

The asthma diagnosis by the following treatment:

If you think you could have silent asthma, you should talk to your doctor. Based on your symptoms, the information you have provided, and your medical history, they could ask for more testing if they think you have asthma. These tests consist of:

  • Spirometry monitors the amount of air that enters and leaves your lungs.
  • The amount of air that can be exhaled with the most effort is called peak expiratory flow.
  • By increasing the amount of nitric oxide you exhale, fractional exhaled nitric oxide evaluates the inflammation in your airways.
  • The bronchoprovocation test assesses how much exposure to allergens alters your spirometry.


Despite the fact that wheezing and coughing are the primary signs of an asthma attack, it is possible to experience an asthma attack without exhibiting those symptoms. After a while, silent asthma can develop into a serious and sometimes fatal condition. By taking your medicine as directed and becoming familiar with the signs of asthma, you can prevent silent asthma episodes and manage your condition effectively.
