Postpartum Complications
Health problems that can arise in the weeks after childbirth
Quick Facts
- Type: Pregnancy-related condition
- When: First days to weeks after delivery
- Common types: Bleeding, infection, clots, mood disorders
- Seek urgent care: Heavy bleeding, high fever, chest pain, severe headache
Overview
The postpartum period, often called the fourth trimester, covers the weeks after childbirth while the body recovers from pregnancy and delivery. Most people heal without serious problems, but a range of complications can occur during this time, and some can be serious or even life-threatening if not recognized and treated.
Postpartum complications include heavy bleeding, infections, blood clots, high blood pressure problems, and mental health conditions such as postpartum depression. Many serious problems develop in the first days to weeks after birth, but some can appear up to a year later. Knowing the warning signs and seeking care promptly is one of the most important ways to stay safe after delivery.
Warning Signs
Certain symptoms after childbirth should prompt urgent medical attention. Seek help if you have:
- Heavy bleeding, such as soaking a pad in an hour or passing large clots
- A fever, foul-smelling vaginal discharge, or worsening pelvic pain (signs of infection)
- Chest pain, shortness of breath, or a leg that is swollen and painful (possible blood clot)
- A severe headache that does not ease, vision changes, or severe swelling (possible blood pressure problem)
- Thoughts of harming yourself or your baby, or feeling unable to cope
Trust your instincts: if something feels seriously wrong, seek care even if it is not on this list.
Common Complications
Several specific conditions account for most serious postpartum problems.
- Postpartum hemorrhage: Excessive bleeding after delivery, most often because the uterus does not contract firmly enough.
- Infection: Of the uterus (endometritis), a cesarean or tear wound, the urinary tract, or the breast (mastitis).
- Blood clots: The risk of clots in the legs or lungs is highest in the weeks after birth.
- High blood pressure disorders: Preeclampsia can begin or continue after delivery.
- Mood disorders: Postpartum depression, anxiety, and the rare but serious postpartum psychosis.
Risk Factors
- Cesarean delivery or a complicated, prolonged labor
- A previous postpartum complication or a history of clots
- High blood pressure or preeclampsia during pregnancy
- Obesity or limited mobility after birth
- A personal or family history of depression or anxiety
- Severe tears or retained placental tissue
Diagnosis
Postpartum complications are identified through symptom review, examination, and targeted tests.
- Examination and observation: Checking bleeding, the uterus, wounds, breasts, and blood pressure.
- Blood and urine tests: To detect infection, anemia, or kidney and liver problems.
- Imaging: Ultrasound for retained tissue or clots in the leg, and lung scans if a clot in the lungs is suspected.
- Mental health screening: Standard questionnaires to detect depression and anxiety.
Treatment
Treatment depends on the specific complication.
- Heavy bleeding: Medicines to help the uterus contract, replacement of fluids or blood, and procedures to remove retained tissue or stop bleeding when needed.
- Infection: Antibiotics, with hospital care for more serious infections.
- Blood clots: Blood thinners (anticoagulants).
- High blood pressure: Blood-pressure medicines and close monitoring.
- Mood disorders: Counseling, support, and medication when appropriate; postpartum psychosis is a psychiatric emergency.
Early treatment greatly improves outcomes, which is why prompt evaluation of warning signs matters so much.
Prevention and Self-Care
- Attend all scheduled postpartum check-ups, including the early ones
- Stay active as able to reduce clot risk, and follow any blood-thinner advice
- Keep wounds clean and watch for signs of infection
- Monitor blood pressure if you had it raised in pregnancy
- Accept support, rest when possible, and talk openly about your mood
- Know the warning signs and have a plan for who to call
When to See a Doctor
Seek emergency care after childbirth for any of these:
- Heavy bleeding (soaking a pad in an hour) or large clots
- Chest pain, trouble breathing, or a painful, swollen leg
- A high fever or foul-smelling discharge
- A severe or persistent headache, vision changes, or severe swelling
- Thoughts of harming yourself or your baby
For thoughts of self-harm or harming the baby, contact emergency services or a crisis line immediately. These symptoms are urgent and treatable.
Frequently Asked Questions
What are the most common postpartum complications?
The most common serious complications are heavy bleeding (postpartum hemorrhage), infections of the uterus, wounds, urinary tract, or breast, blood clots, high blood pressure disorders such as preeclampsia, and mood disorders including postpartum depression.
How long after birth can complications occur?
Many serious complications happen in the first days to weeks after delivery, but some, such as blood clots, preeclampsia, and mood disorders, can appear weeks to months later, even up to a year. Postpartum care continues well beyond the first visit for this reason.
What postpartum bleeding is too much?
Soaking through a pad in an hour, passing clots larger than a golf ball, or feeling faint and dizzy are warning signs of dangerous bleeding. These need urgent medical attention. Some bleeding for a few weeks is normal, but it should gradually lessen.
When is a postpartum mood change an emergency?
Feeling persistently sad, anxious, or unable to cope deserves prompt help. Thoughts of harming yourself or your baby, or losing touch with reality, are emergencies. Contact emergency services or a crisis line immediately, as these conditions are treatable.
Can postpartum complications be prevented?
Many risks can be reduced by attending postpartum check-ups, staying active to lower clot risk, monitoring blood pressure if it was raised, keeping wounds clean, and seeking help early for warning signs. Knowing the danger signs is one of the most protective steps.
