Spleen deficiency may cause frequent urination. As the spleen has the role of transporting water and grain and carrying water and fluid, if the spleen and stomach show weakness and the spleen’s role of transporting water and grain and carrying water and fluid is impaired, it will lead to a decline in the function of the kidneys and a deficiency of kidney qi, which may cause symptoms such as frequent urination. At the same time, spleen deficiency may also be accompanied by symptoms such as loose stools (thin and unformed feces), low food intake, abdominal distension, fatigue (mental exhaustion, physical weakness), low qi and laziness (lack of strength, not wanting to talk), lingering abdominal pain (persistent mild abdominal pain), liking for warmth and pressure, and swelling of the limbs. In addition, heat drenching and kidney deficiency may also cause increased urination. Therefore, if patients experience frequent urination, it is recommended that they consult a hospital to identify the cause and standardize the treatment under the guidance of a doctor. It should be noted that if you drink a lot of water or drink fruit juice, tea and other liquid beverages, it will also lead to increased urination, which is a normal phenomenon and does not require special treatment.
