The phenomenon of excessive urination in women may be related to gynecological diseases, such as chronic vaginitis, which can make the bacteria in the vagina opportunistically invade the urethra, thus causing urinary tract infections, which will result in the phenomenon of excessive urination and frequent urination. There are also cases of pelvic fluid accumulation, which can stimulate the nerves in the pelvis, and produce increased urination. However, when women have excessive urination, it may also be caused by other factors, such as recent psychological stress, catching a cold, staying up late, drinking alcohol, sedentary or having the habit of drinking too much water. All of these problems can cause excessive and frequent urination, as well as when a woman has overactive bladder or has mucosal lesions in the bladder, such as glandular cystitis as well as chronic inflammation of the bladder. There are also cases of internal diseases, such as the early stage of chronic renal insufficiency, which can also lead to increased nocturia, and require systematic examination to clarify.
