Corrections to the energy levels of ground state excitons embedded in a gas of excitons, electrons, and holes are obtained within the framework of the Green's function technique. Contributions of the interaction with free carriers and excitons are considered in the first Born approximation, and plasmon effects are taken into account. Numerical values are given for the exciton energy shift linear in the densities at different temperatures and different electron—hole mass ratios.
