Obesity
Extra weight on the body would make it more difficult to move around. Thus, you can be winded more easily and require more oxygen to do daily activities at work or at home. This is particularly true when you change altitudes or perform lots of physical exercises. In addition, excess fat would block some parts of your blood vessels, making it harder for oxygen to move around. Thus, shortness of breath might happen as a result. Fortunately, this cause can be resolved easily with some lifestyle changes, such as drinking water, limiting unhealthy foods, and doing exercises. [4]
