This fluid can build up in
the arms, legs, lungs and other organs
of the body.
The heart
is working extra hard so sweating occurs. Heart failure also causes breathlessness, confusion, memory problems or disorientation, fatigue and a fast heart rate at times. I had a friend who passed, basically drowning from fluid in his lungs, because of heart failure.
