Study Notes
Pregnancy Adaptations
- Pregnancy significantly alters the cardiovascular, respiratory, and gastrointestinal (GI) systems.
- Increased metabolic demands require dietary and other adaptations.
- Blood volume, heart rate, renal function, metabolism, and respiratory function all change during pregnancy.
- Maternal nutrition provides the nourishment needed for fetal growth and development.
- Physiological synergy involves collaboration between the mother, fetus, and placenta to support life.
- Weight gain during pregnancy depends on pre-pregnancy nutritional status and BMI.
- Underweight (BMI < 18.5) women need approximately 15 lbs.
- Teenage pregnancies require 35-40 lbs.
- Twin pregnancies need 35-40 lbs.
- Triplet pregnancies need approximately 50 lbs.
- Weight reduction during pregnancy is discouraged.
- Average first-trimester weight gain is 2-4 pounds.
- Subsequent trimester weight gain averages 1 lb per week.
- Energy from food fuels increased metabolic needs for mother and fetus, and supports tissue building.
- Complex carbohydrates, monosaturated and polyunsaturated fats, and protein are preferred energy sources.
Protein Needs During Pregnancy
- Protein is crucial for fetal and placental development, maternal tissue growth, and increased blood volume.
- Amniotic fluid creation also uses protein.
- Protein requirements increase by 25g/day or 50% more compared to a non-pregnant woman's needs.
- Protein-rich foods (milk, eggs, cheese, soy, meat) are complete protein sources.
- Incomplete protein sources include legumes and grains, which can be part of a balanced diet.
Mineral and Vitamin Needs During Pregnancy
- Calcium is vital for fetal bone and tooth development.
- Calcium supplements might be necessary if maternal stores are low or pregnancy involves more than one fetus.
- Iron supports hemoglobin synthesis and fetal iron stores.
- Iron supplementation is recommended, taken 1 hour before or 2 hours after meals, with water or orange juice.
- Iron deficiency can lead to preterm delivery and low birth weight.
- A common side effect of iron supplements is black stools.
- Dietary iron is preferable as it has better bioavailability than supplemental iron.
- Vitamins A and C are needed for tissue growth.
- Vitamin B is necessary for various metabolic processes.

Description
This quiz explores the physiological changes that occur during pregnancy, including adaptations in cardiovascular, respiratory, and gastrointestinal systems. It highlights the nutritional needs of the mother and the fetal development process, addressing weight gain recommendations for different pregnancy scenarios. Test your knowledge on how maternal health impacts both mother and child during this critical period.
