After discovering cystitis, do not be too stressed mentally, actively treat it, drink more water, and orally take sodium bicarbonate to alkalinize the urine. This can reduce irritation to the urinary tract. Additionally, medicines like atropine and diazepam can be used, and appropriate heat application to the bladder area, as well as hot water sitz baths, can alleviate bladder spasms. Antibiotics such as cephalosporins and quinolones can be appropriately used. For simple cystitis, you can choose antibiotics that are more sensitive, using a three-day treatment method, which is similar to a seven-day course, with fewer side effects and lower costs. (Please use medications under the guidance of a doctor.)
