The outlook for people with connective tissue diseases is different for everyone. The outlook depends on what type of disease you have, whether or not you get treatment, and how effective the treatment is. Some types of connective tissue diseases may have relatively minor consequences, and some can be fatal (if they affect the lungs, kidneys or heart.) Some types of these diseases are painful, while others have more mild symptoms.
You may be asked to make some lifestyle changes. Also, you may be asked to get vaccines for the flu or vaccine for pneumonia (when your connective tissue disease is in remission).
