  We investigate wormhole solutions using the modified gravity model $f(Q,T)$
with viscosity and aim to find a solution for the existence of wormholes
mathematically without violating the energy conditions. We show that there is
no need to define a wormhole from exotic matter and analyze the equations with
numerical analysis to establish weak energy conditions. In the numerical
analysis, we found that the appropriate values of the parameters can maintain
the weak energy conditions without the need for exotic matter. Adjusting the
parameters of the model can increase or decrease the rate of positive energy
density or radial and tangential pressures. According to the numerical analysis
conducted in this paper, the weak energy conditions are established in the
whole space if $\alpha< 0$, $12.56 < \beta < 25.12$ or $\alpha > 0$, $\beta >
25.12$. The analysis also showed that the supporting matter of the wormhole is
near normal matter, indicating that the generalized $f(Q,T)$ model with
viscosity has an acceptable parameter space to describe a wormhole without the
need for exotic matter.
