Treatment of cystitis includes drinking plenty of water and taking oral sodium bicarbonate to alkalize the urine, reducing irritation to the urinary tract. Atropine and diazepam may be used. Applying heat to the bladder area and taking hot water sitz baths can relieve bladder spasms. Antibacterial drugs such as cephalosporins and quinolones can be used. In recent years, for women with uncomplicated cystitis without complications, sensitive antibacterial drugs can be appropriately used for treatment. Postmenopausal women often experience urinary tract infections frequently. The lack of estrogen, leading to a decrease in lactobacillus in the vagina and an increase in pathogen proliferation, is often a factor in infections. Therefore, adopting estrogen replacement therapy can also maintain the normal vaginal environment and reduce the occurrence of urinary tract infections.
