Cystitis refers to the congestion of the bladder mucosa caused by a bacterial infection, leading to symptoms such as frequent urination, urgency, painful urination, and blood in the urine. In this case, antibiotics can be used for treatment. If necessary, a urine culture and drug sensitivity test should be conducted, and sensitive antibiotics should be selected based on the results. Alternatively, empirical medication using levofloxacin or cephalosporin antibiotics can be employed. After anti-inflammatory treatment, recovery usually occurs within about a week. During treatment, it is important to maintain a light diet and avoid spicy and irritating foods. Drinking more water and urinating frequently can help flush out negative exudates and blood clots from the bladder.
