There is no food to replenish the endometrium after abortion with 0.4cm of endometrium, instead, the endocrine system needs to be adjusted, and estrogenic and progesterone hormone drugs can be taken orally. After abortion, the endometrium will be damaged to some extent due to surgical trauma. Its uterine lining has not been fully repaired and may appear to be 0.4cm. If a woman does not experience other uncomfortable symptoms such as abdominal pain, vaginal bleeding, lower abdominal distension, etc., there is usually no need to worry too much. Diet alone cannot promote the recovery of the uterine lining. Oral estrogen and progesterone medication can be taken under the guidance of a doctor to adjust the menstrual cycle, and the uterine lining will usually return to normal after regular menstruation. Women should follow the doctor’s instructions for regular checkups after the abortion in order to find out whether there is any embryonic tissue left in the uterine cavity.
