Some issues Dr. Jonathan Koff, MD can help you with:

Lung Issues

Every cell in the body requires oxygen to function and produces carbon dioxide as a waste product. In order to keep the body's tissues constantly supplied with fresh oxygen and to keep waste from building up, the lungs pump air in and out, even while sleeping or unaware. Unfortunately, diseases and disorders affecting the lungs are some of the most common medical problems afflicting people around the world. Some of the most common lung problems include asthma, COPD, pneumonia, and lung cancer.

Asthma is a chronic disease where swollen, inflamed airways make it hard to breathe. It is often brought on by specific triggers. While asthma is a common condition, affecting millions of people, it can also be serious and even fatal in severe cases. Treatment involves avoiding triggers and using inhaled corticosteroid medications.

COPD, or Chronic Obstructive Pulmonary Disease, is the name given to two illnesses that both cause difficulty breathing: emphysema and chronic bronchitis. In emphysema, the air sacs of the lungs become damaged, while with bronchitis they become clogged with mucus. COPD is the fourth leading cause of death in the United States. It is almost always caused by breathing irritants into the lungs, such as smoking or heavy pollution.

Pneumonia is a lung infection that can be caused by bacteria, a virus, or fungi. Most healthy people recover from pneumonia in a week or two, but for some people pneumonia can be fatal. There are treatments available for pneumonia, but the best treatment is to prevent getting sick in the first place. People who are at risk should make sure they get a flu shot every year. There is also a vaccine available for the type of bacteria that causes pneumonia.

Lung cancer occurs when abnormal cells inside the lung grow into a tumor, destroying healthy tissue. Because it is so difficult to detect lung cancer in early stages when it has few symptoms, it is the deadliest form of cancer, responsible for the most cancer deaths both in the U.S. and worldwide. Most lung cancer is caused by exposure to tobacco smoke, but between 10-15% of cases are not linked to smoking.

Some problems with the lungs are minor and are not cause for concern. However if symptoms have lasted for a month or more, even if they are minor, it is worth checking with a healthcare professional. A cough, shortness of breath, or excess mucus production that lingers for weeks are all worth getting looked at.

Lung Transplant

Patients who have very severe lung disease may need a lung transplant. The diseased lung is entirely removed and replaced with a healthy lung, usually donated by a person who died. Either one or both lungs can be transplanted.

Contrary to popular belief, lung transplant is rarely used to treat lung cancer. It is a more common treatment for patients with other advanced lung diseases, such as cystic fibrosis, sarcoidosis, pulmonary fibrosis, and chronic obstructive pulmonary disease (COPD). Lung transplant is a serious operation and is generally used as a last resort for patients who have only a short time to live without surgery.

During a transplant, an incision is made on the side of the chest (for a single lung) or in the middle (for both lungs). Patients may be hooked up to a heart-lung bypass machine, which will do the work of moving blood and oxygen through the body during the procedure. After the diseased lung is cut away from the main airway and blood vessels, the donor lung is stitched into place. Surgery may take as long as twelve hours, and a hospital stay of two to three weeks after surgery is not uncommon. For the first hours or day after surgery, patients use a ventilator, or a machine to help them breathe. Tubes will be inserted into the chest to help drain excess air and fluid. During recovery, physical therapy and breathing exercises are used to help the new lung work as well as possible.

Lung capacity is carefully monitored for several months after surgery. Patients who have had a transplant will also have to take anti-rejection drugs for the rest of their lives. These drugs stop the body's immune system from attacking the new lung. The main risks after a transplant are infection and rejection (when the immune system attacks the 'foreign' lung). A healthy lifestyle, including maintaining a diet high in vegetables and lean protein, not smoking, and getting enough exercise, is important to keeping the lungs functioning as well as possible. With proper care, many patients can live ten or even twenty years after a lung transplant.
