Birth Weight

What is birth weight?

Birth weight is the first weight of your baby, taken just after being born. A low birth weight means that the baby is less than 5 pounds, 8 ounces. A high birth weight means that the baby is more than 8 pounds, 13 ounces.

What can cause low birth weight?

A baby with a low birth weight can be born too small, too early (premature), or both. This can happen for many different reasons. They include:

  • Health problems in the pregnant parent
  • Taking certain medicines during pregnancy
  • Substance use during pregnancy
  • Infections during pregnancy
  • Being pregnant with multiple babies
  • Problems with the placenta, the organ that brings oxygen and nutrients to the baby
  • Having small parents
  • Genetic conditions in the baby
  • Birth defects

What problems can low birth weight cause?

Babies with low birth weight may be more at risk of certain health problems. They include immediate problems, such as:

  • Breathing problems
  • Infections
  • Hypoglycemia (low blood sugar)
  • Jaundice
  • Trouble keeping warm

There is also a higher risk of longer-term problems, including:

  • Delayed motor and social development
  • Learning disabilities
  • Certain health conditions as an adult, such as heart disease, high blood pressure, diabetes, and obesity

What can cause high birth weight?

Causes of high birth weight can include:

  • Having big parents
  • Diabetes in the pregnant parent
  • Certain genetic conditions
  • Too much weight gain during pregnancy

What problems can high birth weight cause?

High birth weight can be a concern because it can make delivery of the baby difficult and raise the risk of birth injuries. The baby is at higher risk of problems with:

  • Blood sugar
  • Breathing problems
  • Jaundice

Can birth weight problems be prevented?

You may be able to prevent some birth weight problems by:

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
