Symptoms of cystitis - burning, pain in the urethra, lower abdomen, frequent urination are known to many. Modern medicine considers bacteria and viruses as the most common cause of cystitis - E. coli, proteus, staphylococcus, streptococcus, sexually transmitted infections (gonorrhea, trichomonas, genital herpes, chlamydia, ureaplasma, mycoplasma, Gardnerella).For their diagnosis, urine and blood tests are used. These tests do not always give accurate results, and often do not detect bacteria and viruses. Acute, bacterial cystitis can sometimes be treated with antibiotics. Chronic cystitis is poorly treated.
