Interstitial metaplasia is a change in the lining of a woman’s uterus that is mostly unique to the lining of a pregnant woman’s uterus and may occur in some non-pregnant individuals. The lining of a woman’s uterus after pregnancy is called the meconium, and metaplasia refers to a series of reactions that occur in the meconium after pregnancy. If a woman is pregnant or has had a miscarriage and has endometrial metaplasia on examination, it is a normal reaction. If you are not pregnant but have interstitial metaplasia, it may be due to menstrual disorders, menstrual dysfunction, medication or progesterone, resulting in interstitial metaplasia, which is caused by changes in hormone levels. When the body is in discomfort, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
