Understanding Hypothyroidism and Pregnancy

Pregnancy is a beautiful journey, but when you’re dealing with hypothyroidism, it can feel like you’re navigating uncharted waters. Take a deep breath—you’re not alone, and with the right information and support, you can have a healthy, successful pregnancy.

Why Hypothyroidism Matters During Pregnancy

When your thyroid isn’t producing enough hormones, it can lead to:

• Increased risk of miscarriage
• Preeclampsia
• Premature birth
• Low birth weight
• Developmental challenges for your baby

Don’t worry, though; there is a lot you can do to support your thyroid (and baby) during this exciting time!

Your Comprehensive Survival Guide

1. Pre-Pregnancy Preparation

Before you even start trying to conceive, here’s what you need to do:

• Schedule a comprehensive thyroid panel with your healthcare provider (or consider working with us in our clinic)
• If you’re on thyroid medication, consider working with your prescribing physician to optimize your thyroid medication dosage
• Consider taking a good prenatal supplement like Prenatal Pro by Designs for Health. If you’re in Canada, you can get them here; if you’re American, you can get them here.
• Take 200mcg of seleniomethionine daily with food.
• Check your vitamin D levels to assess whether you’re deficient.

2. Medication Management

Thyroid medication isn’t something to play guessing games with during pregnancy, so if you’re on medication, speak with your prescribing physician.

• Most women require a 30-50% increase in thyroid medication during pregnancy
• Get your thyroid levels checked every 4-6 weeks
• Never stop or adjust medication without professional guidance

3. Nutrition Matters

Your diet can significantly impact thyroid function and pregnancy health:

Key Nutrients to Focus On:

• Iodine: Critical for thyroid hormone production
• Selenium: Supports thyroid hormone conversion
• Zinc: Helps with hormone regulation
• Omega-3 fatty acids: Supports fetal brain development

Recommended Foods:

Wild-Caught Fish

Nutritional Superstars:

• Omega-3 Fatty Acids: Essential for fetal brain development and reducing inflammation
• Selenium: Supports thyroid hormone production and conversion
• Vitamin D: Critical for thyroid function and immune system health – please note that dosing will be based on your levels – do not guess with this!
• Iodine: Crucial for thyroid hormone synthesis – however, taking iodine supplementation should only ever be done with the preemptive work required under the care of an iodine-literate practitioner, or you risk having a flare-up if you have Hashimoto’s.

Specific Benefits:

• Salmon, sardines, and mackerel are particularly beneficial
• Helps reduce autoimmune thyroid activity
• Supports cognitive development of the baby
• Reduces risk of postpartum thyroiditis

Pregnancy Caution: Choose low-mercury fish and limit consumption to 2-3 servings per week.

Eggs

Nutritional Powerhouse:

• Selenium: One egg contains about 20% of daily selenium needs
• Iodine: Critical for thyroid hormone production
• Choline: Essential for fetal brain development
• Protein: Supports overall maternal and fetal health
• Vitamin D: Supports thyroid and immune function

Special Pregnancy Benefits:

• Helps stabilize blood sugar levels
• Provides complete protein with all essential amino acids
• Supports healthy weight management
• Reduces inflammation associated with thyroid disorders

Nuts and Seeds

Nutritional Highlights:

• Selenium: Particularly in Brazil nuts
• Zinc: Critical for thyroid hormone metabolism
• Magnesium: Supports overall hormone balance
• Healthy Fats: Reduces inflammation
• Protein: Supports sustained energy

Specific Seeds and Nuts to Focus On:

• Brazil Nuts: Highest selenium content (just 1-2 nuts meet daily requirement)
• Pumpkin Seeds: Rich in zinc and magnesium
• Chia Seeds: Omega-3 fatty acids and protein
• Almonds: Vitamin E and magnesium

Leafy Green Vegetables

Nutritional Powerhouses:

• Magnesium: Supports thyroid function
• Iron: Prevents anemia common in thyroid disorders
• Vitamin A: Supports immune function
• Folate: Critical for fetal development
• Antioxidants: Reduces inflammation

Top Greens to Incorporate:

• Kale
• Swiss chard
• Collard greens
• Arugula (this green is beneficial if you wrestle with high oxalate greens like spinach, which, on a side note, can be due to a vitamin B6 in the form of P5P deficiency!)

Proteins

Nutritional Benefits:

• Amino Acids: Support thyroid hormone production
• Zinc: Critical for thyroid function
• Iron: Prevents pregnancy-related anemia
• Vitamin B12: Supports energy and metabolism

Best Protein Sources:

• Chicken breast
• Turkey
• Lean beef
• Greek yogurt

Protein is vital; you should aim for a minimum of 100g of protein daily. If you’ve never tracked your protein, I would highly advise you to start for a couple of days to see your baseline.

Pro Tip for Thyroid Health

Cooking and Preparation Matters:

• Choose organic when possible
• Lightly cook vegetables to preserve nutrients, but minimize raw food. Often, women who are exhibiting thyroid strain will have low stomach acid and will wrestle with digesting raw.
• Combine foods strategically (e.g., vitamin C with iron-rich foods helps absorption)
• Stay hydrated
• Consider food combinations that enhance nutrient absorption

4. Lifestyle Modifications

Pregnancy with hypothyroidism requires a holistic approach:

• Prioritize sleep (aim for 8-9 hours)
• Manage stress through meditation or gentle yoga
• Lift weights (your last two reps should be challenging!). This will help you with managing your blood sugar regulation throughout your pregnancy.
• Stay hydrated
• Listen to your body and rest when needed

5. Potential Challenges to Watch For

Be aware of these potential complications:

• Fatigue that goes beyond normal pregnancy tiredness
• Persistent weight gain
• Depression or mood changes
• Constipation
• Hair loss
• Muscle weakness

6. Monitoring and Self-Advocacy

The Power of a Detailed Symptom Journal

Why Keep a Symptom Journal?

Tracking your health is more than just writing down symptoms—it’s about creating a comprehensive narrative of your pregnancy journey, especially with hypothyroidism. Your journal becomes a powerful tool for:

Mastering Medical Appointments

Preparation is Key

Before the Appointment:

• Review your symptom journal

• Note any changes since the last visit

Questions to Always Ask:

1. How do my current thyroid levels compare to previous tests?
2. Are my medication dosages optimal for pregnancy?
3. What additional tests or monitoring do you recommend?
4. Are there any new research or treatments I should know about?
5. How might my thyroid condition impact my pregnancy and delivery?

Remember, self-advocacy isn’t about being combative—it’s about being informed, prepared, and active in your healthcare journey.
