WebDiuretics work by increasing the excretion of sodium from the kidneys, drawing water along with the sodium. Around 180l of water is filtered by the kidneys each day, but only around 1.5l of this will actually leave the body. Filtration occurs in the nephrons of the kidney, when blood passes through the glomerular capillaries at high pressure. WebJan 23, 2024 · National Center for Biotechnology Information
