Reports of severe lung illness experienced by hundreds of people who were using e-cigarettes raise questions again about the safety of vaping. Vaping can help some people stop smoking, but potential health risks likely outweigh any benefit.

While shortness of breath can be caused by several ailments, the most common are a lung issue, a heart problem, anemia (low red blood cell count), or deconditioning. Even if the cause remains unclear, a doctor can create a treatment plan to improve symptoms.

The FDA authorized a brand of smokeless tobacco to use language in its advertising claiming that using snuff reduces risk of lung cancer compared to smoking cigarettes. Technically this is true, but it's not the health advantage the product's maker would like consumers to think it is.

Many COVID-19 symptoms—such as fever, cough, or muscle aches—overlap with the symptoms of other respiratory conditions, such as influenza, a common cold, or asthma. But there are differences among the conditions. For example, a bout of the flu or a cold will not cause shortness of breath the way COVID-19 will. And while asthma can cause shortness of breath, it won’t cause a fever or body aches the way COVID-19 will. A person who’s experiencing concerning symptoms of respiratory illness should report them to a doctor.

About one in eight adults over age 45 has chronic obstructive pulmonary disease (COPD). COPD refers to several lung-damaging conditions, particularly emphysema and chronic bronchitis, that cause coughing and breathlessness. But many people don't know much about COPD, which is largely caused by cigarette smoking and may be mistaken for heart disease. Anyone with symptoms of COPD should be evaluated by a physician. People who have heart disease who have ever smoked or lived with a smoker should be tested for COPD.
