Asthma: the Warning Signs

Asthma can come on suddenly, or its symptoms can be more chronic. The most common symptoms of asthma include:

Asthma triggers may include a common cold, exercise, cold air, and allergens.

What should you do if you have any of these asthma warning signs? Ideally, you and your doctor should have already worked out an asthma action plan. This is a simple set of steps to follow when you have asthma symptoms. Your asthma action plan may include measuring your breathing capacity with a device called a spirometer and taking a dose of quick relief inhaler medication. Your doctor may also want you to change the dose of your daily maintenance therapy to help control your asthma.

Warning Signs of an Asthma Emergency

Some warning signs of asthma are more serious. They include:

  • Symptoms that keep getting worse, even with treatment
  • Difficulty catching your breath or talking
  • Flaring your nostrils as you breathe
  • Sucking in your chest or stomach with each breath
  • Difficulty walking
  • A bluish or grayish tinge to your lips or fingernails

If you have any of these asthma symptoms, call 911.

Anaphylaxis

 Some people's asthma is triggered by allergies. For example, hay fever is a risk factor for developing asthma. Some triggers can make asthma worse, and in some cases a serious type of allergic reaction called anaphylaxis can occur. Anaphylaxis can be caused by food allergies, latex allergies, medication allergies, or allergies to insect stings. Most allergic reactions are localized to one area of your body. An allergic reaction in your skin leads to hives. An allergic reaction in your nose leads to congestion.

But in anaphylaxis, many different organs of your body are affected at once. The results are rapid and life-threatening. Signs of anaphylaxis are:

  • Hives and itchiness
  • Vomiting
  • Diarrhea
  • Pain in the abdomen
  • Severe swelling in the throat that makes it hard to swallow or breathe; this can lead to stridor, or wheezing.
  • Confusion
  • Slurred speech
  • Fast or weak pulse
  • Dizziness (caused by a drop in blood pressure)
  • Unconsciousness

Anaphylaxis is a medical emergency. Keep in mind that anaphylaxis often develops quickly after exposure to the allergen -- possibly within minutes. If you know you’re at risk for anaphylaxis, your doctor should have prescribed an epinephrine injection kit for emergencies (usually two pens). Always carry it with you and do not hesitate to use it to inject yourself, even if you are unsure that your symptoms are allergy related.

Knowing Your Own Warning Signs of Asthma

Of course, the list of asthma symptoms above is only a general guide. Everyone’s case is different, and you may have other asthma warning signs distinct to you.

So, pay attention to your asthma triggers and symptoms. You may notice a pattern that can help guide you. Knowing your personal triggers of asthma allows you to take action early, reducing the severity of your asthma attacks -- or preventing asthma attacks altogether.
