Introduction

In a normal menstrual cycle, the endometrium undergoes cyclical changes under the influence of estrogen and progesterone. The proliferative endometrium can thicken to 8-10 millimeters, and during the secretory phase, it can reach 10-14 millimeters. If the endometrium remains thicker than 5 millimeters after menstruation, or is accompanied by abnormal vaginal bleeding, menstrual irregularities, postmenopausal bleeding, or similar symptoms, it may indicate pathological thickening.

Normally, endometrial thickening refers to a condition where the endometrium exceeds the normal thickness range during ultrasound examination, caused by either physiological or pathological factors leading to abnormal endometrial hyperplasia. Detailed analysis is as follows:

During a normal menstrual cycle, the endometrium undergoes cyclical changes under the influence of estrogen and progesterone. During the proliferative phase, the endometrium can thicken to 8-10 mm, and during the secretory phase, it can reach 10-14 mm. If the endometrium remains thicker than 5 mm after menstruation or is accompanied by symptoms such as abnormal vaginal bleeding, menstrual disorders, or postmenopausal bleeding, it may indicate pathological thickening.

Physiological thickening is often related to the menstrual cycle and generally requires no special treatment. Pathological thickening commonly occurs due to excessive estrogen levels, endometrial polyps, endometrial hyperplasia, endometrial cancer, and other conditions. Diagnosis typically requires hysteroscopy or diagnostic curettage to obtain tissue samples for pathological evaluation, after which drug therapy or surgical treatment may be recommended based on the findings.

If endometrial thickening is detected, timely medical consultation is advised. Evaluation should include consideration of the menstrual cycle and associated symptoms to identify the underlying cause, followed by appropriate treatment as directed by a physician. It is also important to regulate hormone levels in daily life, avoid prolonged estrogen stimulation, and undergo regular gynecological examinations.

Why is the endometrium thin despite high estrogen levels?

In general, high estrogen levels accompanied by thin endometrium may be caused by factors such as irregular lifestyle, excessive mental stress, endometrial damage, polycystic ovary syndrome (PCOS), or hyperprolactinemia. When such conditions occur, it is recommended to seek medical attention promptly to identify the underlying cause and receive appropriate treatment. In daily life, it is important to maintain a regular作息 (sleep-wake cycle), avoid excessive fatigue, eat a balanced diet, and reduce intake of high-sugar and high-fat foods.

Which wild vegetables can treat thickened endometrium?

Currently, there is no sufficient scientific evidence indicating that wild vegetables can treat thickened endometrium. While certain wild vegetables are traditionally believed to have mild regulatory effects, such as dandelion, which is considered cooling in nature and may help clear heat according to traditional beliefs, these effects are limited to general dietary regulation and cannot address the underlying pathological causes of endometrial thickening. Consumption should be moderate, and excessive intake should be avoided to prevent gastrointestinal discomfort.
