Many women have a question about whether fibroids and adenomyosis are the same disease, and if not, what is the difference between the two? How to distinguish them? This article today will take you through the two diseases and how to treat adenomyosis. Adenomyosis and fibroids are both relatively common gynecological diseases, and although the difference between these two diseases is only one word, the difference is very big. First of all, uterine fibroids and adenomyosis are not the same two diseases, the causes of which are different and the symptoms of clinical performance are also different. Uterine fibroids are formed by the proliferation of myometrial cells stimulated by estrogen in the body, and are usually asymptomatic except for submucosal fibroids (a type of uterine fibroid). They are often detected during medical checkups or during examinations for menstrual irregularities. The main symptoms are pain in the lower abdomen, irregular menstruation, and abdominal distention. Adenomyosis is a disease caused by ectopic endometrium in the myometrium. In recent years, the incidence of adenomyosis has been increasing among infertile women due to the delay in their childbearing age. Its main symptom is progressive menstrual pain, which is more severe with each period than the previous one, and can lead to increased menstrual flow and even heavy bleeding. In comparison, adenomyosis is more serious and, while causing severe menstrual pain in women, it can also affect pregnancy and therefore cannot be ignored. Adenomyosis is formed when the endometrium is ectopic to the myometrium. The blood from the ectopic endometrium does not flow out, so it can cause menstrual pain.
