heart disease fluid retention
Why are people with COPD have fluctuating weight gain and fluid retention?
Why some people with lung disease often die of heart failure?
When the lungs are damaged they do not expand as they should. In COPD, small air sacs loses the walls apart and come together, causing a loss of surface. The loss means they surface of oxygen to the blood so the body responds by pumping more blood faster. This puts stress on the heart causing it to enlarge, but eventually weaken. In their struggle to cope and the normal mechanisms the clear fluid pressure in the lungs and the rest of the body stop working properly and fluid builds up. This is usually a problem, especially when sleep night, and patients need to be sustained to breathe properly. It is the additional workload placed on the heart that makes it fail.
