Uterine hypertrophy is a serious gynecological disease, if not effectively treated may cause female infertility situation, seriously affecting the health of women, and the causes of uterine hypertrophy are largely 3 points. The first is chronic inflammation of the uterus in multiple mothers. The number of pregnancies or births in women leads to malignant proliferation of elastic fiber tissue in the myometrium. In addition, long-term chronic gynecological inflammatory stimulation can lead to uterine congestion and edema, resulting in varying degrees of uterine hypertrophy. Secondly, the continuous estrogenic stimulation due to diminished or disrupted ovarian function can lead to hypertrophy of the myometrium. Especially for patients with long-term functional uterine bleeding, it is more common for this group to suffer from uterine enlargement. The third is caused by inflammation, such as pelvic inflammatory disease and chronic myometritis of the uterus causing fibrosis of the uterus, which leads to uterine hypertrophy; in addition, inflammation can cause pelvic congestion, edema and bruising of the uterine tissue, which leads to an enlarged uterus. There are other possible causes of uterine hypertrophy, and I hope that women will be alerted and go to a regular hospital for examination as soon as possible when they experience discomfort, so that they do not miss the opportunity to save their lives because of carelessness.
