Moderate to severe inflammation of the uterus can easily lead to irregular menstruation, dysmenorrhea, uterine polyps and other hazards that need to be analyzed specifically. 1. Irregular menstruation: when moderate to severe inflammation occurs in the uterus, the proliferation and shedding of the endometrium will be affected, thus causing irregular menstruation. 2. Dysmenorrhea: when endometrial inflammation occurs, the menstrual blood will not be discharged properly during menstruation, the uterus will contract excessively, and the small blood vessels in the uterus will have spasms, thus causing dysmenorrhea. 3. Uterine polyps: when the inflammation in the uterus persists, it will cause the local endometrium to proliferate into polyps, and in severe cases, the polyps will also cause infertility. The endometrial inflammation may also produce leukorrhea, induce salpingitis and even infertility, etc. It is recommended that the endometrial inflammation should not be delayed, and go to the hospital in time for standardized treatment to prevent the delay of the condition.
