Yes, it's normal to experience different smells after a C-section due to postpartum hormonal shifts, increased sweating (to shed extra fluid), and normal postpartum discharge (lochia), but a foul, strong, or fishy odor, especially from the incision or vaginal discharge, combined with redness, fever, pus, or increased pain, is a sign of infection and requires urgent medical attention. A mild, metallic, or musty smell from vaginal discharge is typical, but bad smells from the surgical site often signal bacterial buildup or infection, needing prompt treatment.
Even long after surgery, a C-section scar can become infected—especially if moisture or bacteria build up in skin folds. A bad smell, especially a unpleasant odour, can be a sign of a low-grade infection or bacterial overgrowth in the skin folds around the scar.
Like so many other aspects of the postpartum period, how long postpartum body odor lasts can vary and ranges anywhere from a few weeks to a few months. Per Chuang, it usually dissipates between weeks 12 and 16 postpartum, as lochia (i.e. postpartum bleeding) usually resolves during this time.
If your incision smells bad during the first six to eight weeks after surgery, it's possible that you have an infection, Dr. Lamb said. This could either be a bacterial infection of the wound itself, or a yeast infection of the tissue surrounding it, she added.
Everyone's postpartum recovery looks different. For some, the most noticeable odor fades within a few weeks to a few months. For others—especially those who are breastfeeding or experiencing ongoing hormone shifts—it may linger for up to a year.
This hormonal shift can kick your perspiration levels up a notch, leading to that distinct postpartum body odor. So yes, experiencing a change in your body scent during this time is common and just another part of the postpartum package.
Following surgery, you may be less active and spend more time sitting or lying down. This often leads to increased sweating in the treated area, which, combined with bacteria, can produce an unpleasant odor. Keeping the area clean and dry minimizes bacterial growth and associated smells.
Normal lochia after birth has a strong fishy smell like menstruation, lochia usually lasts about 20 days on average, or can be up to 40 - 45 days.
Signs of torn internal stitches may include severe pain, unusual bleeding, swelling, pus, or the wound edges separating. Although this complication is rare, it's important to seek immediate medical advice if you suspect your C-section internal stitches have torn.
Postpartum Vaginal Care: Hygiene Tips for After Giving Birth
You should wash your wound daily, showering is preferable to bathing. Do not use soap on your wound, just use water. Pat the wound dry with a clean towel, avoid rubbing the wound.
You will probably need about 6 weeks to fully recover. It's important to take it easy while the incision heals. Avoid heavy lifting, strenuous activities, and exercises that strain the belly muscles while you recover. Ask a family member or friend for help with housework, cooking, and shopping.
Keep an eye on your scar.
Once you can visualize the incision, you can start keeping an eye on how it's healing. The coloration of the c-section scar should start to fade from red to pink, and it should look pretty uniform. The c-section scar should become less tender to the touch as this happens.
Offensive smell – This may come from your wound or vagina (denoting an infection in the womb, rather than your C-section wound). Some women may struggle to identify what a 'normal' smell is, as there'll be a mix of new smells from you and your baby (breastmilk, baby's nappies, vaginal blood loss, etc.)
A C-section wound should gradually become less painful and look cleaner as the days go by. If it becomes more painful, swollen or warm, this may be a sign of infection. Increased redness spreading around the scar, a feeling of heat, or tenderness that seems to worsen rather than improve are also signs to look out for.
How long do you bleed for after a c-section? You will have some vaginal bleeding (called lochia) for 2-6 weeks after the birth. This is the mucous, tissue and blood that is shed after birth as your womb (uterus) replaces its lining. Bleeding sometimes lasts longer than this, but it should have stopped by 12 weeks.
It takes about six weeks to recover from a C-section, but each woman's timeline will be different. An incision — typically a horizontal cut made in your lower abdomen — can take weeks to heal. During that time, it's recommended that you avoid lifting anything heavier than your baby.
The incision is discharging pus, is open, or has foul-smelling drainage. If you have diabetes, the risk of infection at the incision site is higher. Symptoms of infection include redness and foul-smelling discharge, and the incision failing to heal properly.
You may remove your wound dressing and take showers if stitches, staples, or glue were used to close your skin. Do not soak in a bathtub or hot tub, or go swimming, until your provider tells you it is OK. In most cases, this is not until 3 weeks after surgery.
Does the doctor use the same scar for a second C-section? If you're having a second C-section, normally your surgeon will attempt to cut through the same scar. This might not be possible if there's lots of scar tissue in the area, or if the scar tissue is too thick to cut through.
Infections that develop after delivery of a baby (postpartum infections) usually begin in the uterus. Bacteria can infect the uterus and surrounding areas soon after delivery. Such infections commonly cause pain in the lower abdomen, fever, and a foul-smelling discharge.
While the odor may not be the most pleasant thing to experience, it is a standard for wounds to produce an odor. Wound odor is one of the ways that doctors and nurses can tell if a wound is healing correctly or becoming infected.
Hormonal changes
After giving birth, your body undergoes significant hormonal shifts as it transitions from pregnancy to postpartum. These changes impact everything from your sweat glands to your body's scent. Increased perspiration, combined with bacteria on the skin, can lead to a stronger and more noticeable odor.
Nonenal® (also known as 2-Nonenal) is a naturally occurring compound responsible for the distinct odor associated with aging. It typically appears after age 40, becoming more noticeable in both men and women.
