You need to keep up your nutrition, even if you don't feel hungry or you lose breath whenever you try to eat. It often helps to eat small snacks, and to eat more often. Maintain a good balance between food groups. Keep your fat intake low, but remember that proteins and carbohydrates are essential. Fresh vegetables and fruit maintain the carbohydrates as well as important vitamins.
Fish contains plenty of protein and also important protective oils.
Your doctor, health centre or hospital will be able to point you towards good nutrition advice. All these treatments can be combined together in a team approach. Pulmonary rehabilitation programs aim to improve shortness of breath, give a feeling of control, ease both anxiety and depression, reduce fatigue, make exercise easier, and make overall quality of life better. As you improve you will feel less of a burden on your spouse or other carer, and their enjoyment of life will also pick up. Working with others with similar problems helps you and them.
