Adenomyosis is clinically known as adenomyosis of the uterus, and it is dangerous to have an abortion at age 51 with adenomyosis. Adenomyosis is a limited or diffuse endometriosis of the uterine myometrium, which clinically manifests itself in increased menstrual flow, dysmenorrhea, and menstrual cramps that become increasingly severe. At 51 years of age, it is inherently more dangerous to have an abortion. If you also have adenomyosis, it is even more dangerous to have an abortion, as it may cause poor uterine contraction, which may result in increased bleeding after the abortion. At the same time, the abortion may cause damage to the uterine wall of the patient with adenomyosis, in which case the endometrium will continue to grow along the damaged area of the uterine wall, thus making the patient’s adenomyosis condition more serious. When a 51-year-old adenomyosis patient needs an abortion, it is recommended that the abortion be performed in a regular hospital.
