It is shown that the spectrum of spin-wave excitations in a Heisenberg antiferromagnet can be described consistently in the framework of the method of irreducible Green's functions. The anomalous contributions to the renormalization of the mean field are taken into account from the very beginning. The spin wave damping is calculated self-consistently.
