What is the reason for less menstrual flow after giving birth to a child

After giving birth to a child, the causes of less menstrual flow usually include endocrine changes, endometrial damage, physical weakness, etc. 1. Endocrine changes The hormone levels in postpartum women will fluctuate greatly, especially the changes in estrogen and progesterone levels, which may affect the growth and shedding of the endometrium, resulting in reduced menstrual flow. For example, when lactation prolactin levels are high, ovarian function will be inhibited to a certain extent, so that estrogen secretion is relatively insufficient, and then the endometrium is thin, menstrual volume will become less. 2. Endometrial damage The delivery process, especially cesarean section, may cause a certain degree of damage to the endometrium. If there are endometrial adhesions or partial deletions, the area of the endometrium will be reduced, resulting in less menstrual flow. For example, improper surgical operation or poor postpartum uterine recovery may cause such problems. 3. Weak body production will consume a lot of women's physical strength and qi and blood, postpartum if not get good recuperation, the body is in a weak state, may affect menstruation. Insufficient qi and blood, unable to fully nourish the endometrium, resulting in insufficient proliferation, menstrual volume will be reduced accordingly. If the postpartum menstrual volume continues to be less, and accompanied by other discomfort symptoms, such as abdominal pain, cycle disorder, etc., should seek medical attention in time, carry out relevant examinations, such as ultrasound examination, sex hormone determination, etc., to clarify the cause, and under the guidance of the doctor for targeted treatment and conditioning. At the same time, postpartum women should pay attention to maintain good living habits and mentality, ensure adequate rest and nutrition intake, help the body to recover and menstruation normal.
