We embark on a systematic expansion of dissipative hydrodynamics through the utilization of a Schwinger-Keldysh FT. In this pursuit, we unveil the Navier-Stokes equations as a natural byproduct, emerging elegantly as an energy-momentum balance equation within our novel framework. The fluid system under scrutiny manifests intriguing invariance, showcasing symmetry notably characterized by spatial translation. Our methodology, rooted at the Closed-Time-Path (CTP) formalism, delves into the intricate landscape of hydrodynamic correlation functions and dissipative phenomena. A distinctive feature lies in the preservation of SDiff_ (R^1, 3) symmetry for fluctuation fields, enabling a systematic and rigorous treatment of dissipative hydrodynamics up to second order in derivatives. This approach significantly advances our comprehension of fluid behavior at low energy scales, offering fresh insights and expanding the horizons of theoretical exploration.
