Thirst and frequent urination are considered to be caused by overactive bladder syndrome, and diabetes mellitus is also suspected. The most common cause is urinary tract infection caused by drinking too little water. It is necessary to drink a lot of water, ensuring a daily intake of 1500-2000 ml of water, which can relieve the symptoms in time and can be cured without treatment for relatively minor infections, and if necessary, routine urine and urine culture tests can be done. If it shows white blood cells above the normal range and also red blood cells, it can be treated with oral antibiotics and triple gold tablets. Antibiotics should be chosen from the quinolone group, such as norfloxacin and gatifloxacin. If it is determined to be caused by overactive bladder syndrome, it can be treated with oral solifenacin or mirabellum.
