Study Notes
Pregnancy Adaptations and Nutritional Needs
- Pregnancy significantly alters several bodily systems, including cardiovascular, respiratory, and gastrointestinal (GI) systems.
- Increased metabolic demands during pregnancy necessitate adjustments in dietary habits.
- Key changes during pregnancy encompass blood volume, heart rate, kidney function, metabolism, and respiratory function.
- A pregnant woman's diet provides the essential nourishment for fetal growth and development.
- The mother, fetus, and placenta work together (physiologic synergism) to support the developing life.
- Weight gain recommendations depend on the mother's pre-pregnancy nutritional status and BMI.
Weight Gain During Pregnancy
- Underweight women (BMI < 18.5) should aim for 15–28 pounds of weight gain during pregnancy.
- Teenage mothers may gain approximately 35–40 pounds.
- Women carrying twins might gain 35–40 pounds.
- Triplet pregnancies can result in an overall gain of 50 pounds.
- Weight loss is discouraged during pregnancy.
First Trimester Weight Gain
- During the first trimester, average weight gain is 2–4 pounds.
Second and Third Trimester Weight Gain
- Subsequent trimesters usually see a weekly weight gain of approximately 1 pound.
Nutritional Intake During Pregnancy
- Dietary energy primarily fuels the increased metabolic demands of both the mother and the fetus.
- Protein is crucial for tissue development, including fetal growth, placental development, maternal tissue growth, increased blood volume, and amniotic fluid formation.
Protein Requirements During Pregnancy
- Daily protein needs increase by 25g, equating to 50% more than a non-pregnant woman's requirement.
- Complete protein sources include milk, eggs, cheese, soy products, and meats.
- Incomplete protein sources include legumes and grains.
Vitamins and Minerals Crucial During Pregnancy
- Protein-rich foods contribute calcium, iron, and B-vitamins.
- Calcium is vital for fetal bone and tooth development.
- Calcium supplements might be necessary for mothers with low stores or multiple pregnancies.
- Iron aids in hemoglobin production, fetal iron stores, and prevents preterm labor and low birth weights.
- Increased iron intake can lead to black stools.
- A balanced diet providing iron is preferable to supplements due to bioavailability concerns.
- Vitamins A and C support tissue growth, and vitamin B plays a crucial role in pregnancy.
