How is the thinning of the endometrium caused

Patient's question:

Menstrual flow is very little, have not been pregnant for two years

Doctor's answer:

Hello! The factors or causes of endometrial thinning are divided into systemic factors and local factors. Systemic factors include endocrine disorders, such as low estrogen levels, insufficient progesterone, ovulation disorders, and growth hormone deficiency, among others. Local factors mainly involve endometrial damage, adhesions, and absence, among others.
Guidance: The principle of treating endometrial thinning involves using vaginal four-dimensional color Doppler ultrasound to monitor endometrial thickness and follicle size, as well as hysteroscopy. It is important to rule out local factors before diagnosing systemic factors. Treatment is based on the underlying cause, including hormone supplementation or surgical intervention.
