Initial Steps to Take Before Trying to Conceive
Before trying to conceive, start taking folic acid supplementation (400 mcg daily), achieve a healthy body weight, optimize management of any chronic medical conditions, review medications for teratogenic effects, update immunizations, and undergo appropriate screening for infections. 1
Nutritional Preparation
Folic acid supplementation: Begin taking 400 mcg of folic acid daily at least 3 months before conception to reduce neural tube defects risk by nearly 75% 1, 2
- Higher dosage (4-5 mg daily) is recommended for women with specific risk factors:
- Previous pregnancy affected by neural tube defects
- Taking folic acid antagonists
- Obesity (BMI >35)
- Diabetes mellitus
- Family history of neural tube defects 1
- Higher dosage (4-5 mg daily) is recommended for women with specific risk factors:
Healthy weight: Aim for a BMI between 18.5-24.9 kg/m² 1
- Women who are overweight or obese have increased risks of:
- Diabetes and gestational diabetes
- Hypertension
- Macrosomia and shoulder dystocia
- Operative delivery
- Congenital anomalies
- Intrauterine growth restriction
- Spontaneous abortion and stillbirth
- Preeclampsia and eclampsia 1
- Women who are overweight or obese have increased risks of:
Medical Optimization
Chronic disease management:
Diabetes: Achieve optimal glycemic control before conception, ideally A1C <6.5% to reduce congenital anomalies risk 1
- Poor glycemic control during early pregnancy directly increases risk of congenital anomalies 1
Hypothyroidism: Ensure proper management as dosage requirements increase during early pregnancy 1
Hypertension: Optimize blood pressure control and review medications for pregnancy safety 3
Medication review: Assess all current medications for teratogenic potential 1
Preventive Care
Immunization update: Ensure you're current on:
- Hepatitis B
- Rubella (MMR)
- Varicella
- Tdap (tetanus, diphtheria, acellular pertussis)
- Influenza
- HPV (if indicated) 1
Infection screening: Get tested for:
- Sexually transmitted infections (chlamydia, gonorrhea, syphilis)
- HIV
- Hepatitis B
- Periodontal disease 1
Lifestyle Modifications
Substance use cessation:
Environmental assessment:
- Evaluate workplace exposures to toxicants (healthcare, dry cleaning, printing, manufacturing, agriculture)
- Assess household exposures to heavy metals, solvents, pesticides
- Avoid mercury exposure by limiting consumption of large fish (shark, swordfish, tilefish, king mackerel) 1
Genetic and Family Planning
Genetic screening: Consider screening based on:
- Family history of congenital anomalies
- Ethnic background
- Age
- Carrier testing for conditions like cystic fibrosis when appropriate 1
Reproductive life plan: Develop a plan for:
- When you want to conceive
- Spacing between pregnancies
- Family planning goals 1
Mental Health and Social Support
- Mental health screening: Address:
- Depression and anxiety
- Intimate partner violence
- Major psychosocial stressors 1
Common Pitfalls to Avoid
Waiting until pregnancy is confirmed: Many critical developmental events occur in the first few weeks after conception, often before pregnancy is recognized 1
Overlooking folic acid supplementation: Neural tube closure occurs by 28 days after conception, making pre-pregnancy supplementation essential 1
Neglecting chronic disease optimization: Conditions like diabetes significantly increase risk of birth defects when poorly controlled at conception 1
Assuming all medications are safe: Many common medications are teratogenic and require substitution before conception 1
Delaying immunizations: Some vaccines (like rubella) must be given before pregnancy and require waiting periods before attempting conception 1
By following these comprehensive preconception steps, you can significantly improve your chances of a healthy pregnancy and reduce risks of complications for both you and your baby.
