Postpartum Recovery Science

Understand the scientific laws of postpartum body recovery to help you get through the puerperium better

Uterus Recovery

The uterus shrinks from 1000 g back to 50 g within 6–8 weeks. The fundus descends 1–2 cm daily and enters the true pelvis after 10 days.

  • 1 week postpartum: uterus ≈ 500 g
  • 2 weeks postpartum: uterus ≈ 300 g
  • 6–8 weeks postpartum: uterus ≈ 50 g
Lochia Changes

Lochia lasts 4–6 weeks, total volume ~500–1000 ml. Divided into three stages: bloody, serous, and white lochia.

  • Bloody lochia: days 3–4
  • Serous lochia: days 5–14
  • White lochia: after day 14
Weight Recovery

Postpartum weight loss includes fetus, placenta, and amniotic fluid (~5–6 kg); the rest needs gradual reduction through diet and exercise.

  • Immediately: –5–6 kg
  • 1 week: –2–3 kg more
  • 6 months: target pre-pregnancy weight
Menstruation Return

Timing varies individually; breastfeeding delays return, average 6–8 months postpartum.

  • Non-breastfeeding: 6–10 weeks
  • Mixed feeding: 3–6 months
  • Exclusive breastfeeding: 6–18 months
C-section Recovery

C-section recovery takes longer: wound healing 7–10 days, full recovery 6–8 weeks. Special wound care and infection prevention needed.

  • Wound healing: 7–10 days
  • Full recovery: 6–8 weeks
  • Scar softening: 3–6 months
Pelvic-floor Repair

Postpartum pelvic-floor laxity is common and needs targeted exercise. Kegel is the most effective method.

  • Mild laxity: start exercise at 6 weeks
  • Moderate laxity: needs professional guidance
  • Severe laxity: may need surgery

Postpartum Recovery FAQ

Lochia usually lasts 4–6 weeks, total volume ~500–1000 ml. It is divided into three stages: bloody lochia (days 3–4), serous lochia (days 5–14), and white lochia (after day 14). If lochia lasts more than 6 weeks, has a foul smell, or suddenly increases, see a doctor promptly.

Vaginal-delivery moms can start light exercise at 6–8 weeks postpartum, C-section moms need 8–10 weeks. Begin with walking and pelvic-floor training, then gradually increase intensity. Avoid strenuous exercise within 6 months postpartum.

Timing varies individually: non-breastfeeding moms 6–10 weeks, mixed-feeding moms 3–6 months, exclusive-breastfeeding moms 6–18 months. Breastfeeding inhibits ovulation and delays menstruation return. Even if menstruation hasn’t returned, ovulation may already occur.

Immediately after delivery you lose ~5–6 kg (fetus, placenta, amniotic fluid), then another 2–3 kg in the first week. The remainder needs gradual reduction via reasonable diet and exercise. Aim to return to pre-pregnancy weight by 6 months postpartum, losing ≤0.5 kg per week.

C-section recovery takes longer: wound healing needs 7–10 days, full recovery 6–8 weeks. Special wound care and infection prevention are required. No food for 6 h post-op, ambulation only after 24 h. Avoid heavy lifting and strenuous exercise for 6 weeks.

Postpartum pelvic-floor laxity is common and can be improved with Kegel exercises. Start at 6 weeks postpartum, 3 times daily, 10–15 min each. If symptoms are severe (e.g., obvious urinary incontinence, vaginal laxity), consult a doctor for professional assessment and treatment.

Postpartum depression presents as persistent low mood, anxiety, irritability, insomnia, loss of appetite, etc. “Baby blues” are common and usually resolve within 2 weeks. If symptoms last >2 weeks or worsen, it may be postpartum depression—seek medical help promptly.

The 6-week postpartum checkup is very important; it assesses uterus recovery, wound healing, pelvic-floor function, etc. The doctor will check blood pressure, weight, CBC, and do ultrasound if necessary. This key exam ensures good recovery—don’t miss it.
