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