While scientific advances have dramatically improved the quality of life and life expectancy of people with CF, the majority will need to treat the illness for the rest of their lives. There is currently no cure for CF, although researchers are working on one. The most important thing you can do to help improve your own health and that of people with CF is to maintain a healthy weight, be active, limit your alcohol intake to less than two drinks per day for men or one drink per day for women, eat a balanced diet full of nutritious foods, and avoid smoking. People with CF may also benefit from taking supplements daily. These include vitamins B6 and B12, magnesium, zinc, and fluoroquinolones (such as moxifloxacin or levofloxacin). They may also require treatments such as intravenous antibiotics or lung transplants. As new therapies are developed, it is important to follow them closely so that you do not suffer any side effects. There is still much research to be done in order to find a cure for CF. However, recent advances have led to hopes of extending the lifespan of those with the disease. In addition, clinical trials using bone marrow transplants have shown some promise for improving quality of life issues related to lung function.
