THE PROBLEM
When fluid stays in the tissues
For people living with heart failure, congestion can mean breathlessness, swelling, and repeated hospital care. Established treatments remain essential, but some patients continue to experience difficult-to-treat fluid overload.
The lymphatic system collects excess fluid from tissues and returns it to the bloodstream. When pressure in the veins is elevated, that return can become more difficult. Fluid can accumulate when drainage cannot keep pace.
This makes lymphatic drainage an important pathway to investigate alongside existing heart-failure treatment.
