Symptoms of Fetal Macrosomia

It is very difficult to detect this disease, during the pregnancy. That is why the disease is all the more risky. It can remain undiagnosed for a very long time. These are the common symptoms of fetal macrosomia:

Large Fundal Height

Your doctor can skip out on measuring the fundal height, during your pregnancy. This height is the distance between the top of uterus and the pubic bone. A larger fundal height is a very prominent symptom of fetal macrosomia.

Increase in Amniotic Fluid

If the amount of amniotic fluid is higher, then it is a sign that the baby is larger than average. Amniotic fluid is an amount of urine output of your baby. The increase in size of the child might also increase the amount urinal output.

So far these are the symptoms which can be detectable, as far as the disease is concerned. But it is also essential to know the causes which trigger this kind of syndrome.

Risk Factors Associated with Fetal Macrosomia

There is more than one factor which initiates the risks of fetal macrosomia. There are certain things you can control. But others are out of your hands. The following are the common risk factors associated with the disease:

Maternal Diabetes

If you are already suffering from diabetes, before pregnancy, then the chances are high that your baby might get exposed to the risk of fetal macrosomia. If you have neglected your diabetic tendencies, before pregnancy, your baby might end up with larger shoulders and a huge amount of body fat.

History of Fetal Macrosomia

If you have already given birth to a child with fetal macrosomia, then chances are that your next child will also end up with that disease. Also if you, yourself were an overweight child, during your birth, the risk of the disease remains.

Maternal Obesity

If you are suffering from obesity, then chances are high that your child will suffer from the disease. History of obesity in the family also keeps this risk alive.

Excessive Weight Gain

If you are gaining excessive weight during your pregnancy then you can put your fetus at the risk of this disease. This is also concern for the mothers who were previously obese and again gaining weight during pregnancy.

Repetitive Pregnancies

Studies show that the weight of the child increases upon each pregnancy. For that reason if you are repetitively giving birth to children, then you are putting the new born to risk of being born with a greater body mass than the others.

Having a Male Child

This is something you cannot help. But it is true that male children weigh more than the female counterparts. Male children are at a greater risk of suffering from this disease.

Overdue Pregnancy

If your pregnancy is overdue for more than two weeks then there is a high chance that your baby will weigh more than normal. That is why overdue pregnancies increase the risk of fetal macrosomia.

Age of the Mother

The age of the mother is also another critical factor influencing the weight of the child. Women who are more than 35 years old tend to give birth to larger children than younger women.

Therefore, fetal macrosomia is mostly the result of diabetes, maternal obesity, and excessive weight gain during pregnancy amongst other causes. These are the conditions which you can control and cater to. You can consult with your doctor and undergo tests to make sure that you recover from these conditions and put your child out of the danger zone.
