Small babies may appear physically mature and even have normal length, but retain low body weight and mass.
What Causes a Baby to Be Small?
This is usually genetic, although in most cases, they are as a result of fetal growth problems that could have happened inside the uterus.
A condition called intrauterine growth restriction is a major culprit. This condition stops the baby from getting enough nutrients and oxygen through the placenta from the mother, thereby slowing down growth.
Other factors that might contribute to having a small baby include:
- Chronic kidney disease
- High blood pressure
- Substance abuse (alcohol, Drugs)
Diagnosing the size of your baby is mostly done through regular clinic visits and antenatal tests. Sometimes there could be a problem between the placenta and uterus. Such problems include:
- Decreased blood flow in the uterus and placenta
- Infection in the tissues surrounding the uterus
- Placenta abruption (placenta detaches from the uterus)
- Placenta previa (Placenta attaches low in the uterus)
Your developing baby may also encounter situations that may influence low birth weight. These include:
- If they are more than one (multiple pregnancy)
- Birth defects
- Chromosomal abnormalities
Delivering a Small Baby
Delivery of a small baby is usually done vaginally or through a C section. Key concerns that your delivery team may encounter include:
- Low oxygen levels in your baby
- Low Apgar score
- Meconium aspiration
- Difficulty maintaining normal body temperature.
Prevention of Low Baby Weight
Once you doctors determine that indeed you’re carrying a small baby, you may be booked for more regular visits to monitor any fetal growth problems. Other ways to improve your baby’s weight are such as:
- Stopping smoking or any drug related abuse.
- Eating a healthy diet while pregnant.
- Treatment for small babies (low birth weight)
Once your baby is born, your doctor may consider the following before recommending a course for treatment. These are based on:
- Your baby’s weight and condition
- Mother’s opinion or preference.
- Results of the Apgar score
Treatment will often involve hospitalization and will involve:
- Your child being put on temperature controlled beds
- In babies who may lack a strong suckle, tube feeding may be considered to ensure nutrition
- Low oxygen levels will be constantly monitored and supplemented till an improvement is noted.
A commitment by all mothers to attend regular antenatal check ups go a long way in determining any birth weight related complications and should religiously be attended.
