The symptoms of frequent urination before menstruation are considered to be related to the following factors: First, it may be the premenstrual syndrome that occurs before menstruation. Some women may experience frequent urination before menstruation because of hormonal changes in the body and an increase in prostaglandins, which can cause stimulation of the bladder and urethra. Secondly, frequent urination may also be a symptom triggered by urinary system infection. Inflammatory stimulation of the female urinary system can lead to frequent urination. Thirdly, other gynecological diseases, such as vaginitis and pelvic inflammatory disease, cannot be ruled out completely, and when various diseases appear, the inflammation will spread to the urinary system, resulting in symptoms such as frequent urination and urgent urination. If accompanied by various symptoms such as itching and odor, it is best to go to the hospital for examination and treatment in a timely manner, and it is also recommended to drink more warm water, which can relieve the symptoms of the disease.
