Frequent urination is not necessarily caused by Kidney Yang Deficiency (Shen Yang Xu). Frequent urination primarily refers to an increased frequency of urination. The causes of frequent urination include Bladder Damp-Heat (Pangguang Shi Re), Liver Qi Stagnation (Gan Qi Yu Jie), San Jiao Qi Transformation Dysfunction (San Jiao Qi Hua Bu Li), and Kidney Yang Deficiency (Shen Yang Xu). Frequent urination due to Bladder Damp-Heat is generally accompanied by symptoms such as urinary heat and pain, and treatment requires clearing heat and promoting diuresis.
Frequent urination caused by Liver Qi Stagnation is accompanied by lower abdominal distension and pain, and is more pronounced during times of stress, requiring soothing the liver and relieving tension. Frequent urination due to Kidney Yang Deficiency is usually more noticeable at night, with clear and profuse urine that is pale in color, accompanied by symptoms such as soreness in the lower back and knees, and a fear of cold. Treatment requires tonifying the kidneys, warming Yang, and reducing urination.
