Your breathing test is normal, but you may have mild symptoms such as an on-going cough and increased mucus production. The breathing test shows mild air flow blockage. The test measures the forced expiratory volume in 1 second FEV1.

The stages help describe the condition, but they cannot predict how long a person is likely to survive. In most cases, emphysema and COPD result from cigarette smoking. Other causes appear to be genetic factors, such as an alpha-1 antitrypsin deficiency, and exposure to environmental irritants, including secondhand smoke, workplace pollutants, air pollution, and biomass fuels.

People with small airways in proportion to their lung size may be more at risk than those with wider airways, according to a study. In addition, not all people who smoke develop emphysema. It may be that genetic factors make some people more susceptible to the condition. Treatment cannot cure emphysema, but it can help:. The main medications for emphysema are inhaled bronchodilators , which can help relieve symptoms.

They relax and open the airways, making it easier for a person to breathe. If a person uses them regularly, these options can improve lung function and increase exercise capacity. There are short-acting and long-acting drugs, and people can combine them. Treatment may also change over time and as the condition progresses. People can take steps to manage their symptoms, improve their quality of life, and slow the progression of emphysema.

The sooner a person takes these steps, the more helpful they will be. Pulmonary rehabilitation is a program of care that encourages people with emphysema to learn about and manage their condition.

There is a focus on developing and maintaining healthful lifestyle choices. Making these changes may not alter the overall course of the condition, but it can help people manage the symptoms, improve their exercise capacity, and boost their quality of life.

People should also ensure that they meet with their healthcare provider regularly and receive their routine vaccinations, including those for flu and pneumonia. In time, breathing can become more difficult, and a person may need oxygen therapy some or all of the time. Some people use oxygen overnight, for example. In addition, it has not been shown that pulmonary rehabilitation produces any change in pulmonary function tests PFTs or overall oxygen requirements for individuals.

If medical treatment does not alleviate the symptoms of COPD, or symptoms and exacerbations increase, surgery may be an option. However, in order to be a candidate for surgery, there are specific criteria. These include not being a current smoker, participating in a pulmonary rehabilitation program, and being strong enough to receive surgery.

If damage to the lungs is too severe or surgery does not alleviate symptoms, a doctor may recommend a lung transplant. Call or request an appointment online to get started today. Columbia University Irving Medical Center. Emphysema Emphysema is a progressive, destructive lung disease in which the walls between the tiny air sacs are damaged. COPD vs Asthma COPD and asthma are both obstructive lung diseases marked by shortness of breath but asthma is by definition reversible while with COPD the airflow obstruction is either irreversible or only partly reversible.

Bronchodilators Bronchodilators relax the muscles of the bronchi, the major air passageway in the lungs. This allows air to get in and out easier. These medications are available in pill or liquid form taken orally , or as an aerosol spray inhaled.
