  We consider the $(2+1)$ flavor Polyakov Quark Meson Model and study the
fluctuations (correlations) of conserved charges upto sixth (fourth) order.
Comparison is made with lattice data wherever available and overall good
qualitative agreement is found, more so for the case of the normalised
susceptibilities. The model predictions for the ratio of susceptibilities go to
that of an ideal gas of hadrons as in Hadron Resonance Gas Model at low
temperatures while at high temperature the values are close to that of an ideal
gas of massless quarks. Our study provides a strong basis for the use of PQM as
an effective model to understand the topology of the QCD phase diagram.
