Shortness Of Breath

What Causes Shortness of Breath?

Shortness of breath can have many causes. It can be caused by blockages in the airways due to upper respiratory problems such as asthma, chronic bronchitis, excessive cigarette smoking, and sleep apnea. It can also be caused by the heart's inability to function properly. If the heart is weak, the body becomes overworked, demanding more and more oxygen. If the lungs are damaged in any way they will struggle to keep up with the additional demand, causing the person to breathe harder and harder as physical activity continues. Individuals who are extremely overweight will also have a difficult time maintaining normal respirations during physical activity. The additional weight can stress the heart requiring it to work much harder than normal.

What Kind of Health Problems are Associated with Shortness of Breath?

In most cases, shortness of breath is associated with both pulmonary and cardiovascular health problems. While the lungs are the organs that supplies the oxygen, the heart is responsible for keeping the oxygen moving throughout the body. When a person is extremely overweight or has upper respiratory problems that stress both the heart and lungs, their respiratory rate begins to fluctuate. If a person is severely over weight, the increased pressure on the diaphragm can prevent it from expanding naturally. If an upper respiratory problems is the issue, the lungs themselves may not be able to fully expand and take in the oxygen needed for the body to function.

How is it Treated?

Shortness of breath is often treated with supplemental oxygen dispensed through a canula and a portable oxygen tank. Individuals who are overweight, may be able to improve their breathing by shedding a few pounds and beginning to exercise both their body and their lungs. Those who have upper respiratory issues may be treated with steroids or with inhalers to help improve lung function. The exact cause of the shortness of breath will determine how the doctor chooses to treat the condition. For example, asthma will be treated much differently than a person who has difficulty breathing due to being excessively overweight.
