If you’ve been told “your labs are normal” but you still feel exhausted, foggy, or unlike yourself, you’re not alone—and you’re not imagining it. Thyroid disease, especially when tied to autoimmunity, can be complex, misunderstood, and too often treated with a one-size-fits-all solution. At Brain Health D.C. in Carlsbad, CA, we offer a different path—one that honors your story, investigates the root causes, and empowers you to heal from the inside out.

Welcome to a space where your symptoms are taken seriously, and your healing journey is personal.

Understanding Thyroid Disease

The thyroid gland may be small, but its role in your health is anything but. Located at the base of your neck, this butterfly-shaped gland helps regulate energy levels, metabolism, body temperature, mood, digestion, and hormone balance. When your thyroid isn’t functioning properly, it can affect nearly every system in your body—and leave you feeling like a shadow of yourself.

Types of Thyroid Dysfunction

Thyroid disease comes in several forms, and understanding the root of your condition is essential to truly healing:

• Hypothyroidism (Underactive Thyroid): The thyroid doesn’t produce enough hormones, slowing down metabolism. This is the most common form, especially in women.
• Hyperthyroidism (Overactive Thyroid): The thyroid produces too much hormone, speeding up metabolism and often leading to anxiety, weight loss, and heart palpitations.
• Hashimoto’s Thyroiditis: An autoimmune condition where the immune system mistakenly attacks the thyroid, leading to chronic inflammation and eventual hypothyroidism.
• Graves’ Disease: An autoimmune form of hyperthyroidism where the immune system overstimulates the thyroid, leading to excess hormone production.

Common Symptoms to Watch For

Whether underactive or overactive, thyroid dysfunction can manifest in ways that are often overlooked or misattributed to stress, aging, or mood disorders. Symptoms include:

• Persistent fatigue and sluggishness
• Weight gain or unexplained weight loss
• Cold sensitivity or feeling overheated
• Hair thinning or dry, brittle hair
• Brain fog, forgetfulness, or poor concentration
• Depression, irritability, or anxiety
• Menstrual irregularities, including heavy or irregular periods

If these symptoms sound familiar, you're not alone—and there is a path forward. Through a functional medicine lens, we explore the deeper layers of your thyroid health to bring lasting relief and vibrant energy back to your life.

Why Conventional Treatment Often Falls Short

For many people living with thyroid disease, the journey begins—and ends—with a prescription. Medications like Synthroid (levothyroxine) are often the first line of defense, and while they can help regulate hormone levels, they rarely address the underlying dysfunctions that caused the thyroid imbalance in the first place.

Medication Isn’t a Cure—It’s a Starting Point

While hormone replacement can be helpful for some, it’s not the whole story. Many patients still struggle with fatigue, brain fog, mood swings, and weight challenges even after their labs appear “normal.” This is because medication alone doesn’t address inflammation, autoimmunity, nutrient imbalances, or gut dysfunction—factors that are often at the root of thyroid issues.

One-Size-Fits-All Labs Don’t Tell the Full Story

In conventional care, thyroid testing is often limited to TSH (Thyroid Stimulating Hormone)—a single marker that doesn’t reveal the full picture of thyroid health. In contrast, functional medicine looks deeper, evaluating:

• Free T3 and Free T4
• Reverse T3
• Thyroid antibodies (TPO, TG)
• Cortisol levels
• Nutrient status (selenium, iodine, zinc, iron, vitamin D)

Without these insights, it’s easy for underlying issues to go undetected, and for patients to continue feeling unwell despite being told everything is "fine."

Autoimmunity: The Hidden Root Cause

In many cases, especially in Hashimoto’s and Graves’ disease, the real issue isn’t just hormone imbalance—it’s the immune system attacking the thyroid. If this autoimmune component isn’t identified and addressed, inflammation continues, symptoms worsen, and the thyroid continues to deteriorate over time.

At Brain Health D.C., we do more than manage symptoms. We investigate the "why"—and empower you with answers, strategies, and support to reclaim your health.

Functional Medicine Approach to Thyroid Disease

Functional medicine doesn’t ask, “How do we treat your symptoms?”—it asks, “Why is your body struggling in the first place?” At Brain Health D.C., we take a holistic, patient-centered approach to thyroid disease, looking beyond lab results to understand the full landscape of your health.

We Start With Root Causes

Thyroid dysfunction rarely exists in isolation. Instead, it’s often a symptom of deeper imbalances in the body. Through the functional medicine lens, we explore how these core systems contribute to thyroid dysfunction:

• Gut Health: Leaky gut, dysbiosis, or chronic infections can fuel autoimmunity and hormone imbalances.
• Inflammation: Systemic or localized inflammation stresses the immune system and impairs thyroid conversion.
• Nutrient Deficiencies: Lack of selenium, iodine, zinc, iron, or vitamin D disrupts hormone production and conversion.
• Toxins and Heavy Metals: Environmental exposures can block thyroid receptors or trigger immune dysfunction.
• Chronic Infections: Viral or bacterial triggers (like Epstein-Barr virus) are often linked to autoimmune thyroid issues.
• Stress and Adrenal Dysfunction: Cortisol imbalances impair thyroid hormone conversion and increase inflammation.

Comprehensive Thyroid Testing

Unlike standard protocols, we go far beyond TSH. Our testing is designed to identify the root causes, not just monitor hormone levels. Lab work may include:

• TSH, Free T3, Free T4, Reverse T3 – to understand how your thyroid is functioning and how well your body is converting hormones.
• Thyroid antibodies (TPO and TG) – to detect autoimmune activity like Hashimoto’s or Graves’ disease.
• Inflammatory markers – such as CRP and homocysteine, which indicate immune system stress.
• Nutrient panels – to assess essential vitamins and minerals that impact thyroid health and metabolism.

Personalized Treatment Plans

At Brain Health D.C., there is no one-size-fits-all solution—because no two thyroid journeys are alike. Dr. Nisreen creates highly personalized treatment plans that are grounded in both evidence-based science and deep respect for your individual experience, lifestyle, and goals.

Each plan is designed to support your body’s natural healing abilities and address the root causes of your thyroid dysfunction from the inside out.

Nutritional Strategies

Food is powerful medicine. Your plan may include:

• Anti-inflammatory diets to calm immune activity and reduce symptoms.
• Gluten-free protocols, particularly helpful for autoimmune thyroid conditions like Hashimoto’s.
• Elimination diets to uncover hidden food sensitivities that may be triggering inflammation or fatigue.

These dietary shifts are always personalized and guided with care, not restriction—focused on healing, not deprivation.

Targeted Supplement Protocols

Specific nutrients play a vital role in thyroid function and immune balance. Based on lab results and your individual needs, Dr. Nisreen may recommend:

• Selenium and zinc to support hormone conversion and immune regulation.
• Vitamin D for immune health and inflammation control.
• Iodine—when appropriate and in the correct form—to support thyroid hormone synthesis, only after thorough assessment.

All supplements are thoughtfully selected for quality, dosing, and your unique physiology.

Gut Healing and Detoxification

A healthy gut is essential for a healthy thyroid. Dr. Nisreen may integrate:

• Gut restoration protocols to repair leaky gut, balance microbiota, and optimize digestion.
• Detox support to gently reduce the body’s toxic burden, especially if heavy metals or mold are contributing to thyroid dysfunction.

Stress Reduction and Nervous System Support

Chronic stress is a major driver of thyroid and autoimmune dysfunction. You’ll receive practical, effective tools to:

• Regulate the nervous system through breathing, mindfulness, and movement.
• Restore adrenal balance, improve sleep, and reduce anxiety and overwhelm.

Ongoing Monitoring and Adjustments

Healing is a journey—and we’re with you every step of the way. Dr. Nisreen provides:

• Regular follow-ups and re-testing
• Adjustments to your plan as your body heals
• Education and empowerment so you understand and participate in your progress
