The symptoms of acute UTI are mainly urinary tract irritation symptoms, mostly seen as urinary frequency, urinary urgency and painful urination. Patients with severe infection may be accompanied by peripheral symptoms, such as high fever, chills, nausea, vomiting, dizziness, headache and other symptoms. Acute urethritis is still the result of bacterial infestation. Generally, the human body has a certain resistance to general bacterial infestation, but if the patient has recently had other illnesses that have led to a decrease in physical quality, it is relatively easy to cause other pathogenic bacteria to infest and develop acute urethritis. The most common types of acute urethritis are: 1. bacterial urethritis, such as E. coli infestation leading to acute urethritis, 2. gonococcal urethritis, mainly transmitted by impure sex, often with discharge from the urethra, accompanied by painful urination, etc., which may induce inflammatory conditions in other areas, such as prostatitis, epididymitis, etc., 3. non-gonococcal urethritis, such as ureaplasma solani infection. If the above symptoms appear, it is still recommended to go to a public hospital urology department for regular examination, if necessary, to do urine and secretion culture, choose sensitive antibiotics for treatment to ensure that it can be cured. Do not use random medication and delay treatment.
