What are the common causes of umbilical cord odors?

The umbilical cord is the connection between a mother and her baby in the womb that provides it with nutrients and removes waste. Since the cord is not needed after birth, it is cut into a small piece of tissue that dries up and falls off without the need for additional medical intervention. While cord problems are relatively rare, problems do occasionally arise. One of the most common complications is odors from the umbilical cord. Common causes of cord odors are infection, dirt, bacteria, and harmless odors associated with drying of the cord.

Some level of odor from a newborn's umbilical cord is common and should not be a cause for concern. Normal odors from the umbilical cord are mild and should not be noticed unless the baby's doctor is very close to the stump. To help prevent umbilical cord odors, it's important to keep the area dry and avoid rubbing the diaper on it. The area should be allowed to air dry as much as possible and should not be exposed to lotions or soaps, although rubbing alcohol can be done if necessary. While some parents may be tempted to remove the dry stump, this can cause bleeding and increase susceptibility to infection.

Umbilical cord odors caused by infection will be noticeable during diaper changes and may be accompanied by discharge or pus in the area. An infection can be caused by bacteria or dirt getting into the stump of the cord. Bacteria can come from caregivers who don't wash their hands before cleaning the area or changing diapers, or from the diaper material itself. Newborns can also have a fever due to the infection.

Common signs of an umbilical cord infection include swelling around the cord stump or significant redness in the area. While some bleeding from the stump is normal, excessive bleeding can also be a sign of infection. White or yellow pus draining from the site is a clear indication that the cord stump is not healing properly. The odor from the cord will be unpleasant and may worsen over time.

Umbilical cord infections can be serious and require professional medical treatment as soon as possible. Treatment may include antibiotics or a simple cautery procedure. Any concerns about umbilical cord odors should be discussed with the baby's pediatrician.
