Many patients are confused by all the literature available on what is best for their pregnancy and developing baby. How much should they eat? What vitamins do they need? Can they exercise? How much exercise? How many calories?

This guide is intended to be an overview of that information. Some basic guidelines will be provided here as a resource to reference. As always, if you have any questions regarding if the recommendations are right for you, discuss your questions with your physician.

Nutrition

Nutrition during pregnancy covers two areas. First, what calories are indicated to intake daily, and second, what nutrients should a pregnant woman consume?

Calories

For average weight women pregnant with a single fetus the general recommendation is to add 400 calories daily to their diet. For women pregnant with twins or higher multiples the daily recommendation may increase to 800 calories a day or more.

Weight Gain

Weight gain The Institute of Medicine (IOM) guidelines recommend weight gain during pregnancy based on a woman’s body mass index (BMI) prior to becoming pregnant. For women with a normal BMI prior to pregnancy (18.5-24.9) the recommended weight gain is 25-35 pounds. This usually averages out to ½ pound to 1 pound per week. For a women who is overweight (BMI 25-29.9) the recommended weight gain is 15-25 pounds. Obese women (BMI 30 or greater) should only gain 11-20 pounds. On the other hand, women who are underweight with a BMI less than 18.4 should have a higher weight gain of 28-40 pounds. (ACOG,2013)

Weight is recorded at every prenatal visit and you should review with your physician if you are gaining too much or too little.

Risks of excess weight gain include macrosomia (a larger than average fetus), gestational diabetes, gestational hypertension, intrauterine fetal demise, preeclampsia, thromboembolism, and perinatal mortality (Bautista-Castaño et al, 2013). Also, obese women have almost twice the risk of a cesarean section as women with a normal BMI (Graham et al, 2014).

Vitamins

Exercise

Exercise has known cardiovascular benefits as well as benefits on improving mood and sleep patterns. Exercise through the pregnancy may help protect against excessive maternal weight gain. Exercises that are low impact are generally considered best, such as walking, swimming, cycling, low impact aerobics and yoga, however, running and jogging may be safe for moms who have participated in those activities prior to pregnancy (ACOG,2011). Any activity that could result in trauma through a fall or blow to the abdomen should be avoided, examples include skiing and soccer. Scuba diving should also be avoided during pregnancy.

Any exercise that causes significant abdominal discomfort, bleeding or contractions should be discontinued immediately. Patient should call their doctors if they experience significant pain or bleeding.
