Clinically, patients who experience an increase in the number of urine during the day, or even an increase in the volume of urine, which is normal in the evening, are mostly suffering from some functional disorders, which are not caused by organic diseases. It is generally due to the sympathetic nerves of the human body being more excited during the day, or having recent work stress, high mental tension, or high mental concentration, as well as the surrounding environment being colder, which can lead to the endocrine secretion of the human body. Neurohumoral regulation out is enhanced, which leads to changes in the level of antidiuretic hormone secreted by the hypothalamus, and leads to increased urination. When this phenomenon of increased urine occurs clinically, the patient must also specify whether there are any obvious symptoms of discomfort. These accompanying symptoms are mainly frequent urination, urgent urination, painful urination, and discomfort of lower abdominal cramps after urination. If these clinical manifestations are present, urinary system examinations, such as ultrasound and urine routine, can be performed to evaluate the functional status of the urinary system organs, morphology and physicochemical changes in the composition of urine, to comprehensively evaluate whether the increase in urine is caused by disease. No special treatment is needed.
