Patients with cystitis cannot heal on their own without formal treatment; instead, their symptoms will gradually worsen. The main symptoms of cystitis include frequent urination, urgency, painful urination, and discomfort or pain in the lower abdomen or perineum. After a confirmed diagnosis of cystitis, it is necessary to seek timely treatment at the local hospital's urology department. Treatment can be administered through intravenous antibiotics or by taking oral antibiotics. Additionally, patients should increase their water intake and urinate frequently, as these measures can effectively treat cystitis. Generally, patients can recover within about a week.
