Are COPD patients extremely hungry at times?

Usually not. Most commonly advancing COPD will lead to weight loss. If the person is taking Prednisone for copd, the medication can lead to a substantial increase in appetite and often result in weight gain ( in part due to water retention).
No. Steroids may make COPD pts hungry but overinflation reduces stomach size leading to decreased intake, as COPD progresses weigt loss and decreased appetite ensue as work of breathing outstrips calorie intake. Pts shoul eat multiple small meals daily to combat wt loss.
