What is Umbilical Cord?

The umbilical cord is a tube-like structure that acts as connectivity for the mother and baby. This cord helps to transport food, oxygen, and nutrients from the mother to the baby, which leads to the growth of the fetus. The other names of the umbilical cord are navel string or birth cord, or funiculus umbilicalis. It also helps to carry out the waste materials from the baby to the mom's home. From there, the mother can get rid of these waste materials. Usually, the nutrients can be transported to the baby using this tube from the placenta of the mom. 


Usually, the umbilical cord contains one vein and two arteries. All three perform specific functions. The vein of the umbilical cord helps to transport oxygen and nutrients from the mom to the baby. On the other hand, the arteries help collect the waste material from the baby and get rid of them through the kidneys of the mother. Both arteries and the vein were protected by a gelatin-like substance called Wharton's jelly.

Umbilical Cord After Birth

After delivery, when the mother gives birth to a baby, the newborn umbilical cord then comes off in between 10 to 14 days. In some cases, the umbilical cord falling off will happen around 21 days as maximum. If not, One needs to consult a doctor immediately. Doctors clamp and cut the umbilical cord from the baby after delivery. As the umbilical cord doesn't have any nerves, it may not give any feeling to both mother and baby. A half-size umbilical stump is left over from the baby's navel. It may fall off automatically. 

Appearance

The umbilical cord stump will have a shiny structure with a pale yellow colour in the early stage. After a few days, the colour may turn into different colours like brown, grey or purple-blue, or even black when the umbilical cord is falling off. The colour may change due to the dryness of the cord. 

How to Take Care of the Umbilical Cord Stump?

Till the umbilical cord falls off, one should maintain proper umbilical cord care. Let's have a glance at field tips that help to take care of umbilical cord stumps. 

  • One should be gentle with the baby and the umbilical cord because the cord is very sensitive.

  • Should not put hands on the umbilical cord stump and never try to pull it out because it is a natural process.

  • It is always advisable to give sponge baths instead of putting the baby in a tub or a basin or any other showers.

  • Keep the umbilical cord clean and dry.

  • One should take care while wrapping diapers also.

These are some of the tips that help to take umbilical cord care to avoid unnecessary umbilical cord issues.

Symptoms of Infected Umbilical Cord

One should be cautious and observe the umbilical cord to avoid adverse effects. Here are a few general symptoms which help to identify the infected umbilical cord. 

  • Swelling or rashes around the area of the umbilical cord.

  • Bleeding at the tip of the umbilical cord.

  • White or yellow discharge which looks like pus coming from the umbilical cord.

  • Any irritation or pain felt by the baby when you touch the umbilical cord.

  • Generally, in the case of premature babies, few babies suffer from the infected umbilical cord.

These are the few symptoms observed. When the umbilical cord falls off, a few drops of blood may come out. It is a natural thing, and no need to worry about this. If the umbilical cord blood is too much, then immediately call a doctor and take the advice.

Abnormalities of Umbilical Cord

During the growth of a baby, the umbilical cord may face several abnormalities. Few are very common and have alternatives. But few abnormalities are very severe and need different kinds of treatments. For example, the umbilical cord around the neck is a common cause and can be heard from many mothers. It is also an abnormality of the umbilical cord. It is known as Nuchal Cord. Some of those abnormalities are - 

  • Vasa Previa

  • Nuchal Cord

  • Umbilical Cord Knots

  • Short Umbilical Cord

  • Umbilical Cord Cysts

  • Umbilical Cord Prolapse

  • Single Umbilical Artery

Conclusion

Thus, the umbilical cord is a tough and sensitive tube-like structure that connects the baby to its mom. It is so sensitive and significant. It might be clear how to take care of the umbilical cord stump and the abnormalities and infections that occur to the cord. So, everyone should take proper care and diet and have a happy pregnancy and motherhood by following the suggestions of the doctor.

FAQs on Umbilical Cord

1. What is the umbilical cord and what is its main function?

The umbilical cord is a flexible, tube-like structure that connects a developing baby (fetus) to the placenta during pregnancy. Its primary function is to act as a lifeline, transporting oxygen-rich blood and nutrients from the mother to the baby, and carrying away waste products like carbon dioxide.

2. What are the blood vessels in a normal umbilical cord?

A normal, healthy umbilical cord contains three blood vessels, each with a specific job:

  • One umbilical vein: This large vessel carries oxygenated blood and essential nutrients from the placenta to the baby.
  • Two umbilical arteries: These smaller vessels carry deoxygenated blood and waste products away from the baby and back to the placenta for disposal.

3. What is Wharton's jelly and why is it important?

Wharton's jelly is a gelatinous, connective tissue that surrounds and insulates the blood vessels within the umbilical cord. Its main purpose is to act as a protective cushion, preventing the cord from being compressed or knotted, which could cut off the vital supply of blood and oxygen to the developing baby.

4. What happens to the umbilical cord after a baby is born?

After birth, the umbilical cord is no longer needed, so it is clamped and cut. This process is painless for the baby as the cord has no nerves. A small stump is left attached to the baby's navel, which naturally dries up, shrivels, and falls off on its own, usually within one to three weeks, forming the belly button.

5. How does a single umbilical artery (SUA) differ from a normal cord?

A single umbilical artery (SUA) is a condition where the cord has only one artery instead of the usual two. In this case, one artery must perform the work of two in clearing waste from the baby. While many babies with SUA are born perfectly healthy, it can sometimes be associated with a higher risk of issues with the baby's heart, kidneys, or digestive system, so doctors may recommend extra monitoring.

6. What is vasa previa and why is it considered a serious condition?

Vasa previa is a rare but very serious pregnancy complication. It occurs when the baby's blood vessels from the umbilical cord run unprotected across or very close to the cervix. This is dangerous because the vessels can tear during labour or when the mother's water breaks, leading to rapid and life-threatening blood loss for the baby. Early detection via ultrasound is key to a safe delivery.

7. Why do some medical professionals recommend delaying the clamping of the umbilical cord?

Delaying cord clamping for at least 30 to 60 seconds after birth allows more blood to transfer from the placenta to the baby. This simple practice can significantly increase the baby's iron stores for the first few months of life and improve blood circulation. This ensures the baby receives a final boost of oxygen-rich blood and nutrients before the cord is cut.
