Frequent desire to urinate is a manifestation of frequent urination, which can be divided into physiological and pathological causes. 1. Physiological causes: (1) Drinking too much water: it will lead to an increase in urine volume and trigger frequent urination. (2) Climate change: more urine in winter cold, less urine in summer heat, is a normal physiological phenomenon. 2. Pathologic causes: (1) Urethritis, cystitis, urinary tract stones, urethral polyps and other diseases can trigger frequent urination. (2) Neurogenic urinary frequency: bladder detrusor dysplasia, neurosis, etc., can also trigger frequent urination. (3) other diseases: such as diabetes mellitus, uremia, etc., can also trigger this symptom. The causes of this phenomenon are relatively complex. It is recommended to consult a doctor as soon as possible to confirm the diagnosis and follow the doctor’s instructions for treatment.
