Understanding Asthma - Symptoms and Treatment

Every person’s asthma is different, and not everyone experiences the same symptoms. Wheezing is the most easily recognized symptom of asthma, but there is an argument that a cough is the most common. Other symptoms include shortness of breath or chest tightness.

Many people have combinations of these asthma symptoms, and others may have only one or two. Symptoms may also change over time, for instance, a person who previously had only wheezing and chest tightness, may go on to develop coughing and/or shortness of breath as symptoms.

Wheezing

Wheezing is most often cited as the most common symptom of asthma. [1] Wheezing is a whistling noise that is audible when exhaling, in some cases, it may only be audible via a stethoscope when a doctor or nurse listens to your lungs. [2]

Coughing

Cough is the most common reason people seek medical attention each year. [3] While a cough can accompany other asthma symptoms, cough variant asthma is a type of asthma where a cough is the only symptom a person may have. [4] Often, cough is dry [5], but it can be productive in some cases.

Chest Tightness

People describe chest tightness many ways, including feeling as if a resistance band has been tightened around their chest, or as if something heavy is upon their chest. Chest tightness may develop due to the tightening of muscles around the airways, but some research indicates other components of bronchospasm within the airway may contribute to the sensation of chest tightness. [6]

Shortness of Breath

Also known as dyspnea, the subjective sensation of being short of breath as it varies between each patient can be difficult to explain. It may feel as if you are trying to breathe through a straw, and that you cannot get air efficiently in and out of your lungs. This may be due to a problem called “air trapping,” in which the bulk of air is not able to be exhaled from the lungs. [7]

Changes in Asthma Symptoms

As mentioned, asthma symptoms may change over time, and even from one day or attack to the next. Symptoms can range from mild, which resolve within a few hours, to severe enough to require emergency medical treatment. Having an asthma action plan created by your doctor can help ensure you know how to assess your symptoms, and respond appropriately.

Treatment of Asthma

Treatment for asthma targets the main causes of asthma symptoms—inflammation of the tissues lining the airways and constriction of the smooth muscles around the airways.

Rescue (or reliever) medications are those that are taken only when you have asthma symptoms. These medications work quickly to relieve symptoms, usually within 15 minutes, and last for about 4 hours. Ventolin (salbutamol/albuterol), Xopenex and Bricanyl are examples of short-acting rescue medications. These medications are most often taken by metered dose inhaler or dry powder inhaler, but can also be taken by nebulizer as prescribed by a doctor.

The right medications for you depend on many things — your age, symptoms, triggers and what works best to keep your asthma under control.

Most people will need an daily controller (or maintenance) medications, usually an inhaled steroid—a corticosteroid which fights inflammation—which keeps inflammation under control. Flovent, Pulmicort, Qvar, and Alvesco are examples of these kinds of medications.

Inhaled steroids lead to:

  • Better asthma control
  • Fewer symptoms and flare-ups
  • Reduced need for hospitalization

A long-acting bronchodilator is sometimes combined inhaled steroid to keep asthma symptoms under control. Long-acting bronchodilators are most often prescribed in a combination inhaler with inhaled corticosteroids, such as in Advair, Symbicort, and Dulera.

In some cases, another medication called an anti-leukotriene, or leukotriene receptor antagonist (LTRA) is used, which helps to block a pathway responsible for allergic responses and mucus production—one of these medications, and the most common, is called Singulair. Unlike most other medications, LTRAs can be taken as a pill. A person’s response to LTRAs is very individual—they are not entirely effective for all people.

Asthma management is different for everyone, and different people have different preferences about their treatment and devices used, as well as which medications work for them. It may take trial and error to figure out which medications are best for your asthma.
