Can you give some examples of physical symptoms or maladies attributable to prior surgical disruption of the meridian system?

There can be many consequences, some of which are involved with subsequent physical illnesses within the body. All of the organ functions in their physiologic regulation employ the energies of the meridian system to coordinate things, so any disruption of meridian connectivity, and especially the disruption of chakras themselves, will compromise the communication network and will leave organs somewhat isolated from the communication flow. This will be seen as an underproduction or overproduction of mediators, as well as the decline of function to cause a buildup of waste products or toxins, or the inefficient clearing. So there are a variety of effects that can cause digestive system malfunctions, cardiovascular malfunctions, lung malfunctions, and circulatory and nerve problems of all kinds. There is a long, long, list so there will not be easy things to single out and point to as a culprit.
