A caesarean section, often called a C-section, is a surgical procedure in which a baby is born through incisions made in the mother’s abdomen and uterus rather than through the birth canal. This major operation has become one of the most common surgical procedures worldwide, accounting for roughly one in three births in the United States and about one in four in the United Kingdom.

How Common Are Caesarean Sections Worldwide

Caesarean sections have become increasingly common over the past several decades. In the United States, approximately 30% of all deliveries are performed via C-section, according to the Centers for Disease Control and Prevention^[1]. This represents a dramatic increase from just 5% in 1970 to 31.9% in 2016^[3]. Today, more than one million women undergo caesarean deliveries annually in the United States alone, making it the most common surgical procedure performed in the country^[3].

In the United Kingdom, around one in four pregnant women has a caesarean birth^[4]. The increase in caesarean deliveries can be attributed to various factors, including changes in maternal age, medical advancements that allow more complicated pregnancies to proceed safely, and evolving practices in obstetrics^[3]. While about two in every three births occur vaginally, the caesarean section rate continues to be significant^[5].

Why Caesarean Sections Are Performed

A caesarean section is performed when a vaginal delivery would pose greater risks to the mother or baby. The procedure can be planned ahead of time, known as an elective caesarean, when certain conditions are identified during pregnancy. It can also be performed as an emergency when unexpected complications arise during labor^[1].

Planned Caesarean Sections

Several medical conditions may lead doctors to recommend a planned caesarean section before labor begins. These are typically scheduled from the 39th week of pregnancy onward^[4]. One common reason is cephalopelvic disproportion, a term meaning that the baby’s head or body is too large to pass safely through the mother’s pelvis, or the pelvis is too small to deliver an average-sized baby^[1].

Women who have had a previous caesarean section may need another one, though vaginal birth after caesarean is sometimes possible depending on factors such as the type of uterine incision used previously and the risk of uterine rupture^[1]. Multiple pregnancies often require caesarean delivery, particularly when expecting three or more babies, or when twins are positioned in ways that make vaginal birth risky^[1].

The baby’s position in the uterus is another important factor. A breech presentation, where the baby is positioned feet-first or bottom-first, often necessitates a caesarean section if attempts to turn the baby are unsuccessful^[1]. Similarly, a transverse lie, where the baby is positioned horizontally or sideways in the uterus, typically requires surgical delivery^[1].

Complications with the placenta, the organ that nourishes the baby during pregnancy, can also necessitate a caesarean. Placenta previa occurs when the placenta is attached too low in the uterus and blocks the baby’s exit through the cervix^[1]. Certain maternal health conditions, such as heart disease that could worsen with labor, or active genital herpes at the time of delivery, also make caesarean section necessary^[1].

Emergency Caesarean Sections

Even when a vaginal delivery is planned, complications can arise during labor that require an immediate caesarean section. Prolonged labor, also called labor that isn’t progressing, is one of the most common reasons for an unplanned caesarean. This occurs when the cervix stops dilating, doesn’t thin properly, or when the baby stops moving down the birth canal despite contractions^[1].

Problems with the umbilical cord, which connects the baby to the placenta and provides oxygen and nutrients, can become emergencies. The cord may become looped around the baby’s neck or body, caught between the baby’s head and the mother’s pelvis, or may even come out of the cervix before the baby does, a serious condition called umbilical cord prolapse^[1].

Placental abruption, where the placenta separates from the wall of the uterus before the baby is born, is another emergency that requires immediate caesarean delivery^[1]. Fetal distress, indicated by an irregular heart rate or other signs that the baby is no longer tolerating labor well, may also prompt doctors to decide that a caesarean section is the safest option^[1].

Medical Reasons and Risk Factors

While caesarean sections are not diseases themselves, understanding when they become necessary involves recognizing the conditions that increase the likelihood of needing one. Women who have previously undergone a caesarean section are more likely to need another, though this is not always the case^[5].

The shape of the mother’s pelvis can be a determining factor. Some women have a pelvis structure that makes it difficult or impossible for a baby to pass through safely^[2]. Large uterine fibroids, pelvic fractures, or expecting a baby with certain birth defects may also lead to the need for caesarean delivery^[1].

Certain pregnancy complications increase the risk of requiring a caesarean. High blood pressure in the mother, medically known as pre-eclampsia, twin pregnancies where positioning is problematic, and issues with how the placenta or umbilical cord are functioning all elevate the likelihood of surgical delivery^[2]. Additionally, first-time infections with genital herpes occurring late in pregnancy or untreated HIV require caesarean delivery to protect the baby^[4].

What Happens During the Procedure

Understanding what occurs during a caesarean section can help reduce anxiety for expectant mothers. The entire operation typically takes between 40 to 50 minutes to complete^[4], though the time may vary depending on circumstances.

Preparation and Anesthesia

Before the surgery begins, several preparatory steps take place. The woman signs consent forms and meets with an anesthesiologist to discuss pain management options^[1]. Most caesarean sections are performed using regional anesthesia, either an epidural or spinal block, which numbs the body from the breasts down to the feet while the mother remains awake^[1][4]. General anesthesia, where the patient is completely asleep, may be used in certain emergency situations when the baby needs to be delivered more quickly^[4].

A catheter, a thin flexible tube, is inserted into the bladder to keep it empty during and after the procedure^[1][2]. This typically remains in place for at least 12 hours^[10]. The area where the incision will be made is cleaned with antiseptic, and any hair in the region may be clipped or shaved^[1][2]. Heart and blood pressure monitors are applied, and an intravenous line is placed in the hand or arm to deliver medications and fluids^[1].

The Surgical Process

During the actual procedure, a screen is placed across the mother’s body so she cannot see the surgical area, though doctors and nurses will explain what is happening throughout^[4]. The surgeon makes an incision approximately 10 to 20 centimeters long, usually horizontally across the lower abdomen, just below the bikini line^[2][10]. In rare cases, a vertical incision just below the bellybutton may be necessary^[10].

After the abdominal incision, a second incision is made through the wall of the uterus^[2]. The baby is then carefully delivered through these openings. Women often feel some tugging and pulling sensations during this part of the procedure, even though there is no pain due to the anesthesia^[4]. If the baby is healthy and there are no complications, the mother and her birth partner can see and hold the baby immediately after delivery^[4].

Once the baby is delivered, the surgeon removes the placenta and closes both incisions with stitches^[2]. The wound is typically covered with a dressing for at least the first 24 hours^[10]. Women can usually begin breastfeeding as soon as they are out of the operating room and fully awake^[2].

Recovery After Caesarean Section

Recovery from a caesarean section takes longer than recovery from a vaginal delivery because it is major surgery. Most women stay in the hospital for one to four days after the procedure, though many are discharged after one or two days if there are no complications^[10][16].

Immediate Recovery in Hospital

While in the hospital, women receive pain medication to manage discomfort from the incision^[10]. Healthcare providers encourage new mothers to get out of bed and move around as soon as possible, as this helps prevent blood clots and aids in faster healing^[10]. Women can typically eat and drink as soon as they feel hungry or thirsty^[10]. The catheter usually remains in the bladder for at least 12 hours before being removed^[10].

During this hospital stay, mothers have regular close contact with their babies and can begin establishing breastfeeding^[10]. Medical staff monitor both mother and baby for any signs of complications. When it’s time to go home, women need to arrange for someone to drive them, as they will not be able to drive themselves for several weeks^[10].

Recovery at Home

The first few weeks at home require careful attention to healing and activity restrictions. Most women need pain medicine for the first few days to two weeks^[12]. Common over-the-counter options like paracetamol or ibuprofen are generally safe for breastfeeding mothers, though aspirin and stronger painkillers like codeine are typically not recommended^[10].

Vaginal bleeding, called lochia, occurs even after a caesarean section and can last up to six weeks^[12]. The discharge gradually changes from red to pink, then to a yellowish or white color^[12]. Women should use sanitary pads rather than tampons to reduce the risk of infection^[10].

The incision site requires daily care. Women should gently clean and dry the wound each day, typically while showering with mild soap and water, letting water run over it without scrubbing^[12][9]. If surgical tape strips were used, they should be allowed to fall off naturally, usually within about a week^[12][9]. Non-dissolvable stitches or staples are typically removed by a midwife after five to seven days^[10].

Activity Restrictions

Physical activity must be limited during the healing period. Women should not lift anything heavier than their baby for the first six to eight weeks^[12][9]. Short walks are encouraged as they help increase strength, prevent blood clots, and reduce constipation^[12][9]. However, heavy housework, jogging, most exercises, and activities that cause heavy breathing or muscle strain should be avoided^[12].

Driving is typically not recommended for at least two weeks, and only when women feel safe and are not taking narcotic pain medications^[12]. Riding as a passenger with a properly worn seatbelt is fine^[12]. Taking baths should wait until the incision has healed and postpartum bleeding has stopped; showers are permitted^[9][10]. Public pools and hot tubs should be avoided until cleared by a doctor^[9].

Most women can resume normal activities within four to eight weeks^[12], though full recovery typically takes about six weeks^[2][16]. Sexual activity can usually begin after six weeks, but women should discuss this timing with their healthcare provider at their postnatal checkup^[12]. The six-week postnatal visit is an important opportunity to discuss recovery, any concerns, and contraception options^[10].

The Surgical Scar

The incision creates a scar that changes appearance over time. Initially, the scar appears as a raised, horizontal line about 10 to 20 centimeters long, just below the bikini line^[10]. At first, it will be red and obvious, often appearing slightly puffy and darker than the surrounding skin^[12]. The area remains tender for up to three weeks or more^[12].

Over time, the scar becomes thinner, flatter, and usually fades to match the color of the surrounding skin^[12][10]. It is often hidden by pubic hair. On darker skin tones, the scar tissue may fade to leave a brown or white mark^[10]. Though the scar is permanent, its appearance typically improves significantly with time.

Potential Risks and Complications

While caesarean sections are generally safe procedures, they do carry more risks than vaginal deliveries and are major operations^[1][4]. Understanding potential complications helps women recognize warning signs and seek help promptly when needed.

Risks to the Mother

One of the most common complications is infection, which can occur in the wound or in the womb lining^[4]. Women should watch for signs including increased pain, pus, swelling, redness, swollen lymph nodes, or fever^[9][14]. A fever over 100.4 degrees Fahrenheit requires immediate medical attention^[9][14].

Blood clots are another potential risk, which is why early movement after surgery is strongly encouraged^[4]. Signs of a blood clot include pain in the thigh, groin, back of knee, or calf^[9][14]. Excessive bleeding during or after the procedure is possible, and women should seek immediate care if they experience bright red vaginal bleeding that soaks through more than one pad every two hours or less^[9][14].

During surgery, there is a small risk of accidental damage to nearby organs, such as the bladder or the tubes connecting the kidneys to the bladder^[4]. In rare cases, the baby may be accidentally nicked when the uterus is opened^[4]. Amniotic fluid embolism, where amniotic fluid enters the mother’s bloodstream, and postpartum bleeding are additional risks associated with caesarean delivery^[2].

Implications for Future Pregnancies

Having a caesarean section can affect subsequent pregnancies. The surgical scar on the uterus slightly increases the risk of complications in future births. Women who have had one caesarean may need another, though vaginal birth after caesarean is sometimes possible^[2][4]. Adhesions, bands of scar tissue that can form between internal organs after surgery, may develop and potentially cause complications in future pregnancies^[2].

Risks to the Baby

Babies born by caesarean section may experience temporary breathing difficulties, particularly if the procedure is performed before 39 weeks of pregnancy without a medical reason^[2]. This is why established guidelines recommend avoiding caesarean sections before 39 weeks unless medically necessary^[2]. However, these breathing problems typically resolve quickly with appropriate care.

Emotional Recovery

Physical healing is only one aspect of recovery from a caesarean section. Many women experience complex emotions after the procedure, particularly if it was unplanned or followed a difficult labor. Some mothers feel relieved, while others may feel sad, disappointed, or even guilty about needing a caesarean^[12].

These feelings are normal and can occur even in women who had vaginal births. It’s important to talk with partners, family, or friends about these emotions^[12]. However, if feelings of depression, sadness, hopelessness, or troubling thoughts persist or worsen, women should seek help from their healthcare provider immediately^[9][14]. This could indicate postpartum depression, which requires professional support and treatment.

Nutrition and Self-Care

Proper nutrition plays an important role in healing after surgery. Women should drink plenty of water and other fluids, aiming for about eight cups per day^[9][12]. A well-balanced, healthy diet helps the body repair itself^[9]. Eating plenty of fruits and vegetables supports overall health and helps prevent constipation^[12].

Constipation is a common problem after caesarean section, so taking a daily fiber supplement can be helpful^[9]. Some women may also need bulk laxatives, which their healthcare provider can recommend^[12]. Women should avoid crash dieting and instead ask their doctor when it’s safe to begin trying to lose weight gained during pregnancy^[9].

Rest is crucial for recovery. Women should sleep when their baby sleeps and not hesitate to ask family and friends for help with household tasks, caring for older children, or watching the baby while they nap^[9][12]. It’s normal to feel tired easily, so listening to the body and avoiding exhaustion is important^[12].

Understanding How the Body Changes

A caesarean section involves significant changes to the body’s normal functioning. During the procedure, the surgeon must cut through multiple layers of tissue, including skin, fatty tissue, abdominal muscles, and the muscular wall of the uterus^[3]. Each of these layers must heal, which is why recovery takes several weeks.

The surgical incisions trigger the body’s natural healing response. Inflammation occurs at the wound site as part of this process, which is why the area appears red and swollen initially. Over time, the body produces collagen and new tissue to repair the incision, eventually forming scar tissue. The uterus, which was opened to deliver the baby, must also contract back to its pre-pregnancy size while healing from its own incision.

Hormonal changes that occur after any birth, whether vaginal or caesarean, affect multiple body systems. These hormones influence mood, milk production for breastfeeding, and the process of the uterus returning to its normal size. The sudden hormonal shifts can contribute to the emotional ups and downs many women experience in the weeks following delivery.

The bladder and bowel function may be temporarily affected by the surgery and anesthesia. This is why a catheter is used initially and why constipation is common in the recovery period. The abdominal muscles that were cut during surgery need time to regain their strength, which is why lifting restrictions and exercise limitations are important during healing.
