The uterine cavity may be endometrial polyps, uterine submucous fibroids, etc. The causes are different, and common treatments include medication and surgery. 1. Endometrial polyps: if the polyps are small and have no obvious clinical symptoms, some of the polyps can disappear by themselves, and regular visits can be done; if the polyps are large in size, accompanied by symptoms such as irregular vaginal bleeding, surgical treatment can be taken; if the polyps are older and the effect of repeated treatment is not good, it is recommended to carry out a total removal of the uterus surgical treatment. 2. Uterine submucous fibroid: If the uterine submucous fibroid is small and has no obvious symptoms, it can be left untreated and can be rechecked on time; if there are symptoms such as increased menstrual flow, prolonged menstruation period and leucorrhoea, it can be treated with oral mifepristone as prescribed by the doctor, and it is recommended to have surgery as soon as possible if the symptoms are serious. If there are superfluous organisms in the uterine cavity, it is recommended to consult a doctor in time to avoid delaying the condition.
