Loss of Appetite
When your lungs are affected by inflammation, their volume would be increased significantly in size. This lowers the amount of available space between your stomach and lungs. Thus, these two organs would push against each other when you eat, making it very uncomfortable. Also, emphysema makes breathing more difficult and discourages you from eating as usual. This loss of appetite leads to unexpected weight loss over time. Some foods can even worsen the symptom such as high-fiber foods, caffeine, carbonated drinks, spicy foods, and salty foods. [4]
