There are several reasons for endometrial calcification: First, endocrine system disorders, the hormone levels in the body are affected by the endocrine system, and abnormalities in the endocrine system may lead to too high a level of certain hormones, resulting in too high or too low a concentration of certain ions, leading to endometrial calcification. Secondly, age factor, with age the deposition of calcium on the endometrium, as well as the removal of the decrease, so that the endometrium calcification. Third, blood system diseases, if the blood calcium content is too high, or phosphate content is too high, especially the elevated level of calcium phosphate, easy to make the endometrium calcification. Fourth, dietary habits, also easy to cause endometrial calcification, long-term consumption of calcium-rich foods, such as eggs, meat, etc., can make the body’s calcium content rise, thus accelerating the calcification of the endometrium.
