How long does puerperal sweat usually last?

Puerperal sweat is a phenomenon that many women will experience right after giving birth. After it occurs, as long as the symptoms are not serious, women do not need to take special treatment measures. As long as they take care of their bodies, the problem of puerperal sweat can be greatly improved. They also need to drink enough water every day. They must sweat enough to excrete toxins and avoid toxin accumulation.

After a woman becomes pregnant, in order to meet the needs of the fetus, not only does her nutritional needs increase, but her blood volume also increases. After full term, the mother's interstitial fluid also increases. This includes an increase in body fluid: the average blood volume can increase by 1000~1500ml, and the interstitial fluid can increase by 1500ml. After giving birth, the mother's metabolism decreases and no longer needs as much water, so the body needs to self-regulate and excrete some of the water out of the body.

Generally speaking, there are three ways to excrete water from the body: breathing, defecation, urination, and sweating. Therefore, some new mothers sweat a lot within 2-3 days after delivery, even if they are resting in bed. This kind of postpartum sweating is called "puerperal sweat" in medicine. It is a normal physiological phenomenon and is not caused by "weakness". It is different from sweating caused by long-term illness, serious illness or critical illness. It is not a manifestation of physical weakness. It is a normal physiological sweating and does not require special treatment.

However, due to excessive bleeding during childbirth, the mother is physically and mentally exhausted after childbirth, and her physical condition declines. When she sweats, her pores are often open, which makes it easy for her to be attacked by wind and cold, leading to colds, upper respiratory tract infections and other diseases. Therefore, when you sweat a lot after giving birth, you should be careful to avoid catching cold and change clothes frequently. Before changing clothes, wipe off sweat on your body with a dry towel to keep your skin dry. In addition, drink some warm water or porridge to replenish water.

In mild cases, there are infections of the perineum, vagina, and cervical wounds, perineal lacerations or episiotomy, local redness and swelling, purulent secretions, inability to sit, obvious tenderness, and the wounds split open after stitches are removed, with the surface covered with necrotic tissue. If bacteria invade from the placental detachment surface, they can spread to the entire endometrium and myometrium and cause inflammation. A large number of bacteria spread outward, which can cause pelvic connective tissue inflammation, acute salpingitis, peritonitis, thrombophlebitis, sepsis or septicemia, etc.

Most women start to have a fever 48 hours after delivery, accompanied by dull pain in the lower abdomen, turbid and foul-smelling lochia, and a large amount of lochia. In cases of simple myometritis, the lochia is mostly odorless and small in amount, and the uterus is large and soft with tenderness. When it spreads to the tissues adjacent to the uterus, the patient may have fever, worsening abdominal pain, and thickening and tenderness on one or both sides of the uterus. If it develops into peritonitis or sepsis, the patient may experience chills, high fever, rapid pulse, abdominal distension, severe tenderness in the entire abdomen, rebound tenderness, and abdominal muscle tension. If the bacteria are highly virulent and the body's resistance is low, infectious shock or even death may occur.
