Severe conditions that develop under any tx or procedure, has to be dealt with by the provider, especially if life threatening
. But the patient is
responsible for honestly forwarding what is happening to them to their physician. When they don't, the provider can not make a good medical decission. A 60 lbs wt loss, hgb at 4, arrythmia, etc are things that the MD can see for himself, without the pt's input, but he can not force the pt to accept tx or intervention.
