Urinating more than drinking is mainly considered to be related to physiological factors such as dietary influences and cold stimulation, and pathologic factors such as diabetes mellitus and uremia. 1. Physiological factors: (1) Dietary influences: drinking less water, but consuming more water-rich foods, such as watermelon, pears, etc., can also lead to an increase in the body’s intake of water, resulting in an increase in urine output. (2) Cold stimulation: In order to maintain normal body temperature, it will lead to rapid decomposition of body fat and sugar. Some metabolites will be excreted through urination, which will lead to an increase in urine output. 2. Pathological factors: (1) diabetes mellitus: elevated blood sugar in the body, a large amount of glucose will lead to hypertonic diuresis, triggering the symptoms of polyuria. (2) Uremia: patients with frequent thirst, resulting in increased water intake, urination will also increase accordingly. Even the phenomenon of urinating more than drinking may occur. This phenomenon may also be related to other causes. It is recommended to consult a doctor in time to confirm the diagnosis and take treatment under the doctor’s guidance.
