Gonorrhea complications can occur of gonorrhea is not treated, which can be serious and life threatening. If the bacteria is not treated it can spread into the reproductive tract and in some rare cases into the blood stream. If it spreads into the blood stream it can infect the joints, heart valves, and the brain.
The most common complication in women is pelvic inflammatory disease, or PID. This will most likely show up right after a menstrual period and cause scar tissue in the fallopian tubes, which can lead to ectopic pregnancy. An ectopic pregnancy can lead to a miscarriage and can be life threatening to the mother.
Untreated gonorrhea, in men, can lead to what is called epididymitis, which is a painful condition in the testicles. If this condition is left untreated, it can lead to infertility.
