An asthma attack is a sudden worsening of asthma symptoms caused by the tightening of muscles around your airways (bronchospasm). During the asthma attack, the lining of the airways also becomes swollen or inflamed and thicker mucus -- more than normal -- is produced. All of these factors -- bronchospasm, inflammation, and mucus production -- cause symptoms of an asthma attack such as difficulty breathing, wheezing, coughing, shortness of breath, and difficulty performing normal daily activities. Other symptoms of an asthma attack may include:
Severe wheezing when breathing both in and out
Coughing that won't stop
Very rapid breathing
Chest pain or pressure
Tightened neck and chest muscles, called retractions
Feelings of anxiety or panic
Pale, sweaty face
Blue lips or fingernails
Or worsening symptoms despite use of your medications
When it comes to asthma and appetite, doctors and dietitians worry most about patients who eat too much, shun exercise for fear of becoming breathless, and end up being overweight.
But in a small minority of patients, poorly controlled asthma can leave them too breathless and fatigued to eat properly. Furthermore, a few asthma medications can cause upset stomachs or thrush infections in the mouth, leading to poor appetite.
Some people with asthma may go for extended periods without having an asthma attack or other symptoms, interrupted by periodic worsening of their symptoms, due to exposure to asthma triggers or perhaps from overdoing it as in exercise-induced asthma.
Mild asthma attacks are generally more common. Usually, the airways open up within a few minutes to a few hours after treatment. Severe asthma attacks are less common but last longer and require immediate medical help. It is important to recognize and treat even mild symptoms of an asthma attack to help you prevent severe episodes and keep asthma under control.
What Happens if an Asthma Attack Goes Untreated?
Without immediate asthma medicine and asthma treatment, your breathing will become more labored, and wheezing may get louder. If you use a peak flow meter during an asthma attack, your reading will probably be less than your personal best.
As your lungs continue to tighten during the asthma attack, you will be unable to use the peak flow meter at all. Gradually, your lungs will tighten so much during the asthma attack that there is not enough air movement to produce wheezing. This is sometimes called the "silent chest," and it is a dangerous sign. You may need to be taken to a hospital immediately with a severe asthma attack. Unfortunately, some people interpret the disappearance of wheezing during the asthma attack as a sign of improvement and fail to get prompt emergency care.
If you do not receive adequate treatment for an asthma attack, you will eventually be unable to speak and will develop a bluish coloring around your lips. This color change, known as "cyanosis," means you have less and less oxygen in your blood. Without immediate aggressive treatment in an emergency room or intensive care unit, you may lose consciousness and eventually die.
How Do I Recognize the Early Signs of an Asthma Attack?
Early warning signs are changes that happen just before or at the very beginning of an asthma attack. These changes start before the well-known symptoms of asthma and are the earliest signs that your asthma is worsening.
