Can there ever be a shortage in epinephrine an and(or) nor-epineprine production?if yes, what are the probable causes of d shortage?what is the cure?

Adrenal depletion: Healthy energy levels allow the stress hormones you mention (plus others) to only be called upon for emergencies. Myriad reasons for poor energy can call upon those hormones for everyday things. This gets you through for awhile but taxes the body in many ways and wears those glands out.

No: There could be other factors which could make the effect of Epinephrine and norepinephrine less effective like adrenal insufficiency.
