  We consider the possibility that wormhole geometries are sustained by their
own quantum fluctuations, in the context of noncommutative geometry and
Gravity's Rainbow models. More specifically, the energy density of the graviton
one-loop contribution to a classical energy in a wormhole background is
considered as a self-consistent source for wormholes. In this semi-classical
context, we consider the effects of a smeared particle-like source in
noncommutative geometry and of the Rainbow's functions in sustaining wormhole
geometries.
