Pregnancy Nutrition Counseling

Personalized nutritional guidance to support balanced weight gain, micronutrient adequacy, and fetal development before, during, and after pregnancy.

Indication

• Planning trimester-appropriate nutrition and adequate weight gain in healthy pregnancy
• Preconceptional folic acid and micronutrient assessment before pregnancy
• Medical nutrition therapy in the presence of gestational diabetes or pregestational diabetes
• Excessive or insufficient gestational weight gain, or baseline obesity/underweight
• Management of hyperemesis gravidarum (severe pregnancy nausea and vomiting)
• Pregnancy complications such as iron deficiency anemia, B12 deficiency, and gestational hypertension
• Nutritional support during multiple pregnancy (twins/triplets) and lactation

Preparation

• Bring current gestational week, ultrasound report, and the name of your obstetric provider
• Share recent blood tests (CBC, ferritin, B12, vitamin D, fasting glucose, OGTT)
• Bring a list of vitamin-mineral supplements and medications you use
• Note your prepregnancy weight, current weight, and weekly weight changes
• Share complaints (nausea, constipation, reflux) and any history of pregnancy complications

How it's performed

1. The dietitian assesses eating habits, food intolerances, and aversions
2. Height, weight, and arm/waist circumference (when needed) are measured; target weight range is set based on prepregnancy BMI
3. Trimester-specific energy needs (typically +340 kcal in the second and +450 kcal in the third trimester), protein, calcium, iron, folic acid, and omega-3 are planned
4. Food safety guidance is provided (raw meat, unpasteurized dairy, high-mercury fish)
5. Practical nutritional strategies are given for nausea, constipation, and reflux
6. Supplement doses and follow-up intervals are coordinated with the physician/midwife

Post-procedure

• Generally at least one visit per trimester; more frequent in high-risk pregnancies
• At each visit weight changes, edema, blood pressure, and laboratory values are reviewed
• The plan is revised based on the OGTT result (24-28 weeks)
• After delivery, an additional ~500 kcal/day is planned for the lactation period
• At 6-8 weeks postpartum, maternal weight, iron/B12 levels, and breastfeeding adequacy are evaluated

Risks

• Insufficient folic acid intake increases the risk of neural tube defects (spinal cord developmental defect)
• Underweight or undernutrition increases the risk of preterm birth and low birth weight
• Excessive weight gain increases the risk of gestational diabetes, macrosomia (large baby), and preeclampsia
• Uncontrolled vegetarian/vegan diets may cause B12, iron, and omega-3 deficiency
• Uncontrolled supplement use can cause toxic effects of fat-soluble vitamins such as vitamin A (especially in the first trimester)
