Feeling breathless during a vigorous workout is a common experience that generally is not cause for concern, according to Medline, a division of the National Institutes of Health. However, there are circumstances when shortness of breath can point to a more serious condition, such as asthma or heart disease. Though most breathing problems are easily treatable, any breathing problem requires consultation with your health care provider, MedlinePlus advises.
When to Seek Emergency Help
Medline Plus recommends seeking emergency attention if breathing difficulties come on suddenly, or if someone stops breathing altogether. Chest pain, discomfort or pressure in the chest or lung area could indicate a heart attack. Call your health care provider if you develop fever, wheezing and/or cough, as this may indicate bronchitis or another illness.
Take Precautions If Condition Worsens
Sometimes feeling out of breath is a normal reaction to strenuous exercise, for example, if you don't exercise regularly, or are experiencing severe congestion. However, "if difficulty breathing is new or is getting worse, this may indicate a serious problem," Medline Plus states.
Possible Causes
Possible causes of shortness of breath may include a blockage in your nose mouth or throat. Heart problems can lead to shortness of breath if the heart is not able to pump enough blood to supply adequate oxygen to the body. At times, emotional stress and anxiety can cause breathing difficulties. In addition, asthma or allergies can contribute to breathing problems during exercise.
About Asthma
Exercise-induced shortness of breath or chest tightness is a common manifestation of asthma, according to the University of Iowa. They caution that in general asthma is completely treatable, and should not limit a person from being active. Your doctor may prescribe an inhaled bronchodilator to be used before exercise.
Deep Breathing
Some people have mild physical conditions that cause inefficient, abnormal breathing patterns, according to Medical News Today. For example, during exercise, they are breathing too fast or shallow to utilize their full lung capacity. Sometimes strenuous exercise can lead to hyperventilation.
HIgh Altitudes
If you are not accustomed to high altitudes, sometimes a workout can be much more challenging in these environments. Other causes of heavy breathing can include a large amount of dust, pollen or pollution in the air, reports Medline.
Testing
Breathing problems can be tested by your physician, who will likely check your lungs, heartand upper airway passages. Common tests that are used to determine the cause of shortness of breath include measurement of blood oxygen saturation, pulmonary function tests, chest X-ray and exercise -- treadmill -- testing.
