In late pregnancy, reduced urine output is generally due to a high-salt diet. If decreased urination occurs during the final stage of pregnancy, it is usually a normal physiological phenomenon. Women experience water and sodium retention during pregnancy, and regularly consuming foods high in salt can affect the body's metabolism, thereby reducing urine volume. Drinking plenty of warm water during pregnancy can help maintain normal urine output.
