If a female patient has frequent urination with bloating symptoms, the first thing to consider is a bladder infection. Cystitis is mainly caused by retrograde bacterial infection, such as women with vaginitis or lack of hygiene during sex, bacteria can enter the urethra retrogradely through the urethra and gradually spread to the bladder and cause inflammation of the bladder. Some patients also have symptoms such as painful urination, incomplete urination, pain in the small abdomen, and in severe cases, bloody urine, chills and fever. In this case, you need to go to the urology department of the hospital in time to do urine routine, urine culture and drug sensitivity test to clarify the specific causative agent of cystitis, and then choose a sensitive antibiotic for treatment. During the treatment period, pay attention to a light diet, do not eat spicy and stimulating food, drink more water and urinate regularly, relying on the flushing effect of urine to flush out the inflammatory exudate and bacteria from the bladder, which is conducive to the recovery of the disease.
