This study focuses on the investigation of traversable wormhole solutions in the framework of f(G, T) gravity. The Gauss-Bonnet invariant is denoted by G, and T represents the trace of the energy-momentum tensor. By carefully selecting specific forms for the red-shift function and the f(G, T) model, explicit expressions for ordinary matter are derived. The research thoroughly examines anisotropic, isotropic, and barotropic matter distributions to assess the feasibility of wormholes. Through graphical analysis, it is demonstrated that the effective energy-momentum tensor consistently violates the null energy condition throughout its evolution. However, within certain regions for each matter distribution, ordinary matter satisfies the energy constraints. This finding suggests that these traversable wormhole solutions can be considered physically viable within the framework of this theory.
