      breast changes

      When a pregnant woman becomes a new mother, the main change in her breasts is the start of lactation. Maternal breasts are usually Postpartum That is, it begins to fill and harden, and there is induration when touched, followed by milk secretion. Postpartum breast changes will cause some problems. For example, postpartum mastitis usually occurs in the 10th day after delivery? 14 days, especially among first-time mothers. The main cause of the disease is that the body's resistance decreases after delivery, which makes it easy for bacteria to invade, grow, and reproduce. Treatment generally includes bed rest, hot compresses, fluid intake, and antibiotics. If symptoms are very severe, you should arrive promptly Hospital See a doctor. In addition, new mothers may have sagging breasts. Some mothers think that breast sagging is caused by breastfeeding. In fact, breast changes are caused by pregnancy, not breastfeeding. As long as you use suitable bra support and pay attention exercise The pectoralis major muscle can gradually improve.

      Uterus changes

      During pregnancy, various systems of the mother's body adapt to fetus To meet the needs of growth and development, a series of adaptive physiological changes must be carried out, with the uterus experiencing the greatest changes. Before pregnancy, the uterus is only the size of a pear, but by the time the pregnancy is full term, the uterus will become like a large winter melon. After the fetus and placenta are delivered, the uterus will immediately contract and gradually return to normal size. This process is called uterine involution.

      The speed of uterine recovery depends on the maternal age, healthy The condition, length of labor, mode of delivery, number of deliveries, and whether you are breastfeeding all matter. Generally speaking, due to the delivery of the fetus and the stripping of the placenta, a wound is formed on the surface of the endometrium, which needs to wait until 6 weeks after delivery, that is, 42 days, to fully heal. At this time, the uterus can basically return to its non-pregnant state.

      After delivery, the cervix appears relaxed, congested, and edematous; by about 1 week after delivery, the external shape and internal os of the cervix return to their original shape; the internal os closes at about 2 weeks; and returns to normal size by 4 weeks. Due to birth contusion, the cervix will change from the round shape before delivery to a transverse cleft.

      Changes in the perineum

      The vulva of mothers who give birth naturally will suffer from edema and pain due to compression and tearing during childbirth. These symptoms will disappear within a few days after delivery.

      When mothers giving birth for the first time give birth naturally, due to factors such as the tight perineal area, large fetal head circumference, and midwifery operations, it is easy to cause perineal tears and injuries. In order to avoid this situation, many mothers will undergo an episiotomy. Therefore, after delivery, new mothers who have undergone lateral incision need to pay attention to the care of the perineum, keep the perineum clean and dry, and avoid wound infection.

      After delivery, the vaginal cavity of a new mother gradually shrinks, and the vaginal wall muscle tension gradually recovers. The dilation phenomenon that occurs after delivery can be restored after 3 months. If the muscles in the vagina are damaged through squeezing and tearing, their recovery will take longer. In addition, some exercises are needed in time after delivery to strengthen the recovery of elasticity and promote vaginal firmness.

      Low back and leg pain

      Many women experience lower back and leg pain after giving birth. This is because during pregnancy, the development of the fetus increases the size of the uterus, and at the same time the abdominal circumference and weight increase. The enlarged abdomen protrudes forward. In order to adapt to this physiological change, the center of gravity of the body must change, and the load on the lower back increases. Therefore, pregnant women often feel soreness in the lower back and legs. When it's time to give birth, the mother usually lies on her back. She spends a long time on the delivery bed and cannot move freely. During delivery, a lot of physical strength and heat energy are consumed, which aggravates the pain in the waist and legs.

      In addition, during the confinement period, some mothers do not pay attention to scientific rest methods. Various situations may cause the mother to feel pain in the waist and legs after delivery. The pain in the waist and legs that a mother feels after giving birth is generally a physiological change and can be recovered. If the pain does not relieve but gradually worsens, it is necessary to seek timely treatment from a doctor.

      changes in urination

      During pregnancy, a woman's body retains a large amount of water, so the urine output increases significantly in the early puerperium. In addition, some new mothers also experience urinary incontinence. The internal causes of urinary incontinence are female The urethra is relatively short. The external cause is that the fetus passes through the birth canal during delivery, which causes the muscle membrane of the bladder, uterus and other tissues to be injured, elasticity is damaged, and the urethra relaxes and loses its proper function.

      Therefore, pregnant women should avoid premature labor and pay attention to prevention constipate , but also consciously do anal contraction exercises regularly to slowly restore the contractility of the pelvic floor muscles. After a period of time, the incontinence will relieve and disappear on its own. If the condition does not improve, you need to see a urologist or obstetrician.

      skin , body shape and other changes in appearance

      During pregnancy, many expectant mothers have varying degrees of pigmentation on their skin and stretch marks on their lower abdomen. After childbirth, the pigmentation in the midline of the lower abdomen will gradually disappear; however, the purple-red stretch marks that appear on the abdomen will turn into permanent silver-white old stretch marks. The abdominal skin is affected by the expansion of the uterus during pregnancy, the elastic fibers are broken, and the abdominal muscles are separated to varying degrees. The abdominal wall shows obvious relaxation after delivery, but it will recover after 6 to 8 weeks.

      After a woman gives birth, the male hormones in her body suddenly return to normal, stimulating hair loss, which manifests as postpartum hair loss.

      Due to the decrease in estrogen and progesterone levels after childbirth, new mothers are prone to chloasma on their faces, and most women's bodies will undergo significant changes after giving birth, such as a bulging abdomen, a thick and round waist, and wide hips.
