The endometrium, as a crucial part of the female reproductive system, its thickness changes not only reflect a woman’s physiological health but also are closely related to the menstrual cycle. Many women have questions: What is the normal thickness of the endometrium? At what thickness does menstruation occur? Let’s explore these topics in detail.
The thickness of the endometrium is not constant; it fluctuates cyclically with the menstrual cycle. A complete menstrual cycle is typically divided into the menstrual phase, the proliferative phase, and the secretory phase.
During the menstrual phase, the endometrium sheds and bleeds, and at this time, the endometrial thickness is the thinnest, generally about 1 – 4 millimeters.
After menstruation ends, the proliferative phase begins. Under the action of estrogen, the endometrium starts to repair and gradually thickens, increasing from 4 – 5 millimeters to 8 – 10 millimeters.
In the secretory phase, progesterone takes effect, and the endometrium continues to thicken in preparation for the implantation of a fertilized egg. At this time, the endometrial thickness can reach 10 – 14 millimeters. If no fertilized egg implants, the endometrium will start to shed again, entering the next menstrual cycle.
So, at what thickness does menstruation occur? Generally, when the endometrial thickness reaches around 8 – 12 millimeters, the conditions for menstruation are met. However, this is not an absolute value, as the menstrual cycle is also affected by various factors such as endocrine, emotions, and the environment.
For example, long – term high stress and irregular daily routines may lead to endocrine disorders, which in turn affect the normal growth and shedding of the endometrium, causing menstrual cycle disorders and altering the relationship between endometrial thickness and menstruation.
In addition to the above, there are some highly concerned questions about endometrial thickness and menstruation:
Q: What are the impacts of abnormal endometrial thickness?
A: An overly thin endometrium may be caused by multiple factors such as repeated abortions, endocrine disorders, and endometrial diseases. This can affect the implantation of a fertilized egg, increase the risk of female infertility, and may also lead to scanty menstruation.
On the other hand, an overly thick endometrium may be related to high estrogen levels, endometrial hyperplasia, etc. Long – term excessive thickness poses a potential risk of developing endometrial cancer and may also cause symptoms such as heavy menstruation and prolonged menstrual periods.
Q: How is endometrial thickness detected?
A: The most commonly used detection method is ultrasound examination. Through B – ultrasound, the thickness, morphology, and echo of the endometrium can be clearly observed. It is generally recommended to conduct multiple detections at different stages of the menstrual cycle, which can provide a more comprehensive understanding of the changes in the endometrium.
In addition, hysteroscopy can directly visualize the endometrium, but it is an invasive examination and is usually used when endometrial lesions are suspected.
Q: How can an overly thin endometrium be regulated?
A: First, adjust your lifestyle. Maintain a regular schedule, avoid staying up late, and ensure sufficient sleep. Have a reasonable diet and consume more foods rich in estrogen, such as beans and soy products, grains, and nuts.
Second, if the thin endometrium is caused by endocrine disorders, medication for endocrine regulation should be used under the guidance of a doctor. For cases where the endometrium is damaged and thinned due to abortion surgery, drugs to promote endometrial repair can be used as prescribed by the doctor.
