Thick endometrium can usually be helped by taking oral progesterone to help the lining fall off; however, food, in general, does not have pharmacological effects, so food will not help the endometrium fall off. Thick endometrium is generally caused by excessive proliferation of the endometrium. Excluding pregnancy, lesions and other factors, you can follow the doctor’s instructions to take oral progesterone to help the endometrium fall off, such as progesterone capsules, dydrogesterone tablets and so on. However, it should be noted that oral progesterone may cause nausea, vomiting, so you need to follow the doctor’s advice, not recommended to take oral medication at will. Generally, after taking oral progesterone, about 1 week after stopping the medication, there will be withdrawal bleeding, and after the bleeding is over, the uterine lining will generally become thinner. If there is still no obvious effect after medication, it is recommended to consult a doctor in time to choose the rest of the appropriate treatment.
