Postpartum chills and shivering can feel alarming for new mothers. Have you experienced sudden shaking, your teeth start to chatter or uncontrollable shivers right after delivery, even when the room isn’t cold? These episodes are common, but they often leave mothers wondering if something is wrong.
In most cases, postpartum chills after 1 week result from rapid hormonal changes, fluid shifts, and the physical stress of labor. This article explains why they happen, how long they usually last, and when it’s important to call your doctor for further evaluation.
Dr. Laura Riley, an obstetrician at Weill Cornell Medicine, explains that “postpartum shivering is typically harmless and self-limited, but persistent episodes deserve medical attention.” In the next sections, we’ll explore the causes, simple remedies, and expert-backed insights to help you manage postpartum chills with confidence.
What Causes Postpartum shaking?
Postpartum shaking can occur for several reasons, ranging from hormonal shifts to the body’s response to labor. The intensity varies: some women may experience mild trembling, while others have uncontrollable shivers that feel similar to intense chills.
Below are the most common causes:
1. Hormonal Fluctuations
During pregnancy, estrogen and progesterone levels rise dramatically. After delivery, these hormones plummet quickly, triggering physiological reactions such as shivering, mood changes, and night sweats. These shifts are part of the body’s natural reset after childbirth.
2. Adrenaline and Birth Stress
Labor is a physically demanding process. The adrenaline released during childbirth can linger, leading to involuntary shaking after delivery. This reaction is particularly common in the first few hours postpartum.
3. Anesthesia or Epidural Side Effects
Women who receive an epidural or spinal anesthesia may notice chills and trembling as the medication wears off. This is a common side effect caused by the body’s reaction to anesthesia and changes in blood pressure.
4. Fluid and Blood Loss
Childbirth involves significant fluid shifts. Blood loss, dehydration, or the rapid return of blood circulation to normal levels can trigger shivering episodes as the body works to stabilize itself.
5. Temperature Regulation
Many women experience drastic body temperature changes during and after birth. Sweating followed by chills, or an inability to regulate body heat, is often due to the body recalibrating after pregnancy.
When Should You Worry about Postpartum Shaking?
Although postpartum shaking is usually harmless, there are times when it may indicate something more serious. Understanding when to worry is crucial for ensuring your safety and health.
Normal Postpartum Shaking
- Occurs within the first few hours after delivery.
- Lasts for a few minutes to one hour.
- Resolves on its own without intervention.
- Not associated with other concerning symptoms.
When It May Signal a Problem
Seek medical attention if you notice:
- Persistent or Severe Shivering: Tremors that continue for days or worsen instead of improving.
- High Fever: A temperature above 100.4°F (38°C) often indicates an infection.
- Chest Pain or Shortness of Breath: These could be signs of a blood clot or another serious complication.
- Dizziness or Fainting: May point to excessive blood loss or severe dehydration.
- Confusion or Disorientation: Could indicate infection or other underlying issues.
If any of these symptoms occur alongside shaking, it’s best to contact a healthcare provider immediately.
How Should You Feel 1 Week Postpartum?
At one week postpartum, your body is still in recovery mode. Here’s what you should expect versus what may indicate any health problems:
What’s Normal
- Mild Fatigue and Weakness: Labor and delivery place enormous strain on the body, and it’s normal to feel tired.
- Light to Moderate Vaginal Bleeding (Lochia): This gradually decreases in flow and changes from bright red to pink, then brown.
- Mild Discomfort or Cramping: Your uterus continues shrinking back to its pre-pregnancy size.
- Occasional Sweating or Chills: Hormones are still shifting, and your body may struggle with temperature regulation.
When to Be Concerned
- Heavy Postpartum Bleeding: Soaking a pad in an hour or passing large clots can signal postpartum hemorrhage.
- Fever and Severe Chills: May indicate infection.
- Intense Abdominal Pain: Could be a sign of retained placenta or infection.
- Depression or Anxiety: While “baby blues” are common, persistent or severe physical and emotional struggles may signal postpartum depression.
Monitoring your recovery during this first week is critical. Keeping track of symptoms and communicating concerns to your doctor helps ensure a safe healing process.
Postpartum Chills and Other Signs of Infection
While hormonal changes and adrenaline surges explain most postpartum chills, sometimes shivering is a red flag for infection. Recognizing additional symptoms can help distinguish between normal recovery and a serious complication.
Possible Postpartum Infections:
Endometritis (Uterine Infection)
- Symptoms: Fever, abdominal pain, foul-smelling vaginal discharge, persistent chills.
- Risk Factors: Prolonged labor, cesarean delivery, or retained placenta.
Urinary Tract Infection (UTI)
- Symptoms: Painful urination, frequent urge to urinate, cloudy or strong-smelling urine, fever.
- Risk Factors: Catheter use during delivery, dehydration.
Mastitis (Breast Infection)
- Symptoms: Red, swollen, or painful breast, fever, chills, flu-like symptoms.
- Risk Factors: Blocked milk ducts or cracked nipples during breastfeeding.
Wound or Incision Infection
Symptoms: Redness, swelling, pus, or pain around a C-section incision or episiotomy site.
Risk Factors: Poor wound healing, diabetes, obesity.
When to Call a Doctor Immediately?
If you experience shivering alongside fever, foul-smelling discharge, abdominal pain, or wound complications, it is crucial to seek medical attention right away. Postpartum infections can progress quickly and require antibiotics or other medical treatments.
Commonly Asked Questions about Postpartum Chills and Shivering (FAQs)
When to call your doctor about postpartum chills?
Call your doctor about postpartum chills immediately if accompanied by trouble breathing, fever over 100.4°F, or signs of deep vein thrombosis (leg pain/swelling). These may indicate infection or serious complications requiring urgent care.
What are postpartum chills and shivering?
Postpartum chills and shivering are common experiences for many women in the days following childbirth. These sensations can occur as a result of hormonal changes, physical exhaustion, and heat loss that the body undergoes after giving birth. While they can be uncomfortable, they are usually considered a normal part of the postpartum recovery process.
What causes postpartum chills?
The causes of postpartum chills can vary widely. Factors may include hormonal fluctuations, the body’s adjustment to temperature regulation after childbirth, and even the effects of anesthesia if a cesarean section was performed. Additionally, intense shivering may occur during the first few days postpartum as the body works to stabilize itself after the stress of labor.
Are postpartum chills a sign of infection?
While chills following birth can be totally normal, they could also indicate an infection, particularly if accompanied by other symptoms like fever or foul-smelling discharge. If you experience persistent chills that last longer than an hour or have other concerning symptoms, it is important to contact your health care provider right away for peace of mind.
When do postpartum chills typically occur?
Postpartum chills often occur during the first six weeks after birth, particularly in the first few days as the body is adjusting. Some women may experience shaking after birth immediately following delivery, especially if they received neuraxial analgesia or had a vaginal birth. The experience can vary among individuals.
How can I manage postpartum chills?
To manage postpartum chills, it is helpful to keep warm with blankets and clothing. Skin-to-skin contact with your new baby can also help regulate your body temperature and provide comfort. Staying hydrated and resting can further support your recovery during the postpartum period.
Should I worry about postpartum shivering?
Experiencing postpartum shivering phenomenon is usually a normal occurrence, but if the shivering is intense or accompanied by other symptoms, it may be wise to consult your health care provider. They can help determine if the shivering is part of the normal recovery process or if it requires medical attention.
How long do postpartum chills last?
Postpartum chills can last for a few minutes to several hours, often resolving within the first few days. However, if the chills persist beyond this period or if you have concerns about your postpartum health, it is advisable to reach out to your health care provider for guidance.
What should I do if I got postpartum chills?
If you got postpartum chills, it’s important to monitor your symptoms. Ensure you are warm and comfortable, and consider speaking with your health care provider if the chills are severe or persistent. Keeping an eye out for additional symptoms can help ensure that any potential issues are addressed promptly.
What are the symptoms of pulmonary embolism after giving birth?
Symptoms of pulmonary embolism after giving birth include sudden shortness of breath, chest pain (worse when breathing), rapid heart rate, coughing (sometimes bloody), and fainting. Seek emergency care immediately—it’s life-threatening.
Can I do pelvic floor exercises 1 week postpartum?
Yes, you can start gentle pelvic floor exercises (like Kegels) 1 week postpartum if delivery was uncomplicated. Go slowly, stop if painful, and consult your doctor—especially after a C-section or severe tearing.
Conclusion
Postpartum Chills and Shivering are a common part of recovery, usually caused by hormonal shifts, adrenaline, or anesthesia. Most women experience these tremors within the first few hours after birth, and they resolve on their own. However, ongoing or severe shaking, especially when accompanied by fever, pain, or heavy bleeding, should not be ignored.
At one week postpartum, your body is still healing, and while mild discomfort, fatigue, and temperature fluctuations are normal, any warning signs of infection or excessive bleeding require urgent evaluation.
By understanding what’s normal and what’s not, you can confidently navigate postpartum recovery and know when to seek help. Always prioritize your health—recovery is not just about rest, but also about recognizing when your body needs medical attention.
