Why is tracking your weight during pregnancy essential?

According to a study conducted by the National Center for Health Statics, only 32% of expecting mothers gained the recommended amount of weight. 21% of all mamas gained too little. And nearly half (48%) gained too much. To improve your chances of having a healthy baby, tracking your weight gain week by week, or even day by day, is important to lowering the risks associated with being under and overweight.

Increased Risks if Underweight

Miscarriage. An unplanned loss of a pregnancy. [REFERENCE]

Premature birth. Also known as preterm birth, an infant is born before 37 weeks of pregnancy. [REFERENCE]

Gastroschisis. A birth defect of the abdominal wall. The intestines are found outside of the baby’s body, exiting through a hole beside the belly button. [REFERENCE]

Low birth weight. The medical term is Small for Gestational Age (SGA) and serves as an indicator that a child has been malnourished. Infants considered SGA are at risk for health and development problems as they get older. [REFERENCE]

Increased Risks if Overweight

Gestational diabetes. Diabetes that starts during pregnancy for mothers. If not controlled, the condition may lead to high blood pressure and a more serious condition called preeclampsia. [REFERENCE]

Cesarean section. Procedure where the baby is delivered through an abdominal incision. Also called a c-section or cesarean birth. [REFERENCE]

Heart and neural tube defects. The most common example is spina bifida, a failure of a fetal spine to close the right way when it is developing before birth. [REFERENCE]

Metabolic syndrome and childhood obesity. [REFERENCE]

How much weight should you gain when pregnant?

While day-to-day weight gain will fluctuate, the general guideline suggests an expectant mother should gain between 25 to 35 pounds during the course of pregnancy. However, according to the Institute of Medicine, the recommended, healthy pregnancy weight gain changes significantly based on two factors:

  • Your BMI; and
  • The number you're carrying.

BMI stand for Body Mass Index and serves as a rough estimate for body fat based on your weight and height. As your body fat increases above what's considered "normal", the number of pounds, or kilograms, you're expected to gain decreases. And conversely, as your body fat decreases below what's considered "normal", the amount you're expected to gain increases.

The number of beans you're carrying can also impact your ideal weight gain. When carrying twins or triplets, your guideline for target weight gain increases.

Determining your recommended weight gain during pregnancy involves three steps:

  1. Using the BMI calculator below, determine your BMI at the start of your pregnancy.
  2. Using the pregnancy weight gain charts below, find your corresponding weight gain according to how many beans you've got baking in the oven.
  3. Confirm with your health care provider that the target weight gain applies to your circumstance. Every mama and bean is unique.
