  We perform a global fit within the inert doublet model taking into account
experimental observables from colliders, direct and indirect dark matter
searches and theoretical constraints. In particular, we consider recent results
from searches for dark matter annihilation-induced gamma-rays in dwarf
spheroidal galaxies and relax the assumption that the inert doublet model
should account for the entire dark matter in the Universe. We moreover study in
how far the model is compatible with a possible dark matter explanation of the
so-called Galactic center excess. We find two distinct parameter space regions
that are consistent with existing constraints and can simultaneously explain
the excess: One with dark matter masses near the Higgs resonance and one around
72 GeV where dark matter annihilates predominantly into pairs of virtual
electroweak gauge bosons via the four-vertex arising from the inert doublet's
kinetic term. We briefly discuss future prospects to probe these scenarios.
