If you bypass someone or something that you would normally have to get involved with, you ignore them, often because you want to achieve something more quickly.
A bypass is a surgical operation performed on or near the heart, in which the flow of blood is redirected so that it does not flow through a part of the heart which is diseased or blocked.
If a surgeon bypasses a diseased artery or other part of the body, he or she performs an operation so that blood or other bodily fluids do not flow through it.
