Hypothyroidism

What is Hypothyroidism?

• Definition: Hypothyroidism is a condition where the thyroid gland is underactive, resulting in insufficient production of thyroid hormones.

• Thyroid Hormones: These hormones (T3 and T4) are crucial for regulating metabolism, energy levels, and overall bodily functions.

• Classification:

  • Primary Hypothyroidism: The thyroid itself is malfunctioning (very rare, less than 10% of cases)

  • Secondary Hypothyroidism: The issue arises from the pituitary gland not producing enough TSH (thyroid-stimulating hormone).

  • Tertiary Hypothyroidism: Problems originate from the hypothalamus, affecting TRH (thyrotropin-releasing hormone) production.

What does Hypothyroidism do in our body?

• Metabolism: Slows down metabolism, leading to weight gain and fatigue.

• Heart Rate: Affects heart rate, often causing bradycardia (slower heart rate).

• Thermoregulation: Impairs thermoregulation, making individuals sensitive to cold.

• Cognitive Function: Influences cognitive function, leading to forgetfulness and brain fog.

• Mood: Alters mood, contributing to feelings of depression or anxiety.

What causes Hypothyroidism?

• Autoimmune Disorders: Conditions like Hashimoto's thyroiditis, where the immune system attacks the thyroid.

• Previous Treatments: Surgery or radioactive iodine treatment affecting the thyroid.

• Nutritional Deficiencies: Lack of iodine, essential for hormone production.

• Medications: Some drugs (e.g., lithium, amiodarone) can disrupt thyroid function.

• Genetic Factors: Family history may increase susceptibility.

Major Warning Signs of Hypothyroidism

• Fatigue: Persistent fatigue or noticeable decreases in energy.

• Weight Changes: Unexplained weight gain or difficulty shedding pounds.

• Cold Sensitivity: Increased sensitivity to cold temperatures.

• Skin and Hair: Changes in skin and hair, such as dryness or hair loss.

• Digestive Issues: Muscle weakness or joint pain.

Symptoms of Hypothyroidism

• Facial Swelling: Swelling in the face, particularly around the eyes.

• Hoarseness: Hoarseness or changes in the voice.

• Menstrual Changes: Heavy or irregular menstrual periods.

• Mental Health: Mental health challenges, including depression and anxiety.

• Cognitive Issues: Cognitive issues, like forgetfulness and brain fog.

How does Hypothyroidism affect the Immune System?

• Immune Response: This can weaken the immune response, increasing susceptibility to infections.

• Autoimmunity: This may trigger other autoimmune disorders as the body’s defence systems malfunction.

How does Hypothyroidism affect the Cardiovascular System?

• Cholesterol Levels: Increases LDL cholesterol levels, raising the risk of heart disease.

• Heart Rate: Potential for bradycardia and low blood pressure.

• Heart Enlargement: Severe cases can lead to heart enlargement (cardiomyopathy).

How does Hypothyroidism affect the Integumentary System?

• Skin Issues: Causes dry skin, hair loss, and brittle nails.

• Facial Puffiness: May lead to puffiness, especially in the face.

How does Hypothyroidism affect the Lymphatic System?

• Lymphatic Flow: Slowed lymphatic flow, possibly leading to fluid retention and swelling.

• Lipedema: An increasing number of women discovering the link between this fat disorder and thyroid disease.

• Immune Defenses: Weakened immune defences may hinder the body’s ability to fight infections.

How does Hypothyroidism affect the Endocrine System?

• Hormonal Imbalance: Disrupts hormone balance, affecting sex hormones and cortisol levels.

• Metabolism: Can impair glucose metabolism and insulin sensitivity, increasing diabetes risk.

How does Hypothyroidism affect the Muscular System?

• Muscle Weakness: Causes muscle weakness and stiffness.

• Cramps: May lead to cramps and muscle pain due to metabolic slowdown.

How does Hypothyroidism affect the Digestive System?

• Gastrointestinal Motility: Slows gastrointestinal motility, leading to constipation.

• Appetite Changes: Alters appetite and weight, impacting digestive health.

How does Hypothyroidism affect the Nervous System?

• Cognitive Issues: Contributes to cognitive issues, such as memory loss and difficulty concentrating.

• Peripheral Neuropathy: May lead to peripheral neuropathy, resulting in tingling or numbness.

How does Hypothyroidism affect the Skeletal System?

• Bone Density: Decreased bone density, heightening osteoporosis risk.

• Joint Pain: Joint pain and stiffness can occur due to metabolic issues.

How does Hypothyroidism affect the Thyroid Pathway?

• Hormone Production: Inhibits hormone production, disrupting the feedback loop (thyroid pathway) with the pituitary gland.

• TSH Levels: Leads to elevated TSH levels as the body tries to stimulate the thyroid.

How does Hypothyroidism affect the Liver?

• Metabolism: Slows liver metabolism, impairing detoxification.

• Fatty Liver: May contribute to fatty liver disease due to altered lipid processing.

Physical Ailments that affect Hypothyroidism

• Mental Health Disorders: Increased risk of depression and anxiety due to high number of T3 receptors in the brain.

• Cardiovascular Issues: Higher risk of heart disease and hypertension.

• Musculoskeletal Disorders: Conditions like arthritis may be more common.

• Sleep Disorders: Insomnia or excessive daytime sleepiness can be prevalent.

Food that impacts Hypothyroidism

• Goitrogens: Foods like soy and raw cruciferous vegetables can inhibit thyroid function when consumed excessively.

• Iodine-Rich Foods: Seaweed, fish, and dairy support thyroid health but should be balanced to avoid excess.

• Selenium-Rich Foods: Brazil nuts and mushrooms may enhance thyroid hormone production.

Medications that Impact Hypothyroidism

• Other Medications: Some medications (e.g., lithium) can interfere with thyroid hormone synthesis.

• Vitamin D: Important for immune health and may influence thyroid activity. Learn More

• Zinc: Aids in thyroid hormone synthesis and immune function. Learn More

Heavy Metals that Impact Hypothyroidism

• Lead: Interferes with hormone synthesis and metabolism. Learn More

• Mercury: Disrupts endocrine function, potentially harming thyroid health. Learn More

• Cadmium: Disrupts endocrine function and hormonal pathways. Learn More

Testing for Hypothyroidism

• TSH Test: Measures thyroid-stimulating hormone levels to assess function.

• Free T4 and Free T3 Tests: Evaluate the levels of active thyroid hormones.

• Reverse T3: Evaluate stress levels and how much of active hormone is being converted back into non-active form.

• Antibody Tests: Help diagnose autoimmune thyroid conditions like Hashimoto’s.

Treatment for Hypothyroidism

• Levothyroxine: Commonly prescribed synthetic hormone replacement.

Nutrients for Hypothyroidism

• Iodine: Essential for hormone production; deficiency can lead to hypothyroidism. Learn More

• Selenium: Crucial for converting T4 to the more active T3 hormone. Learn More

• Zinc: Supports hormone synthesis and immune health. Learn More

• Vitamin D: Important for overall health and thyroid function. Learn More

• Tyrosine: The “T” in the T3 & T4, an amino acid derived from Protein. Learn More

Alternative Therapies for Hypothyroidism

Lifestyle Modifications:

• Stress Management: Techniques such as yoga, meditation, or deep breathing exercises to reduce stress, which can impact thyroid health.

• Regular Exercise: Engaging in regular physical activity to help maintain a healthy weight and boost energy levels.

• Acupuncture:

  • May help improve energy levels and balance hormones by promoting overall well-being.

• Chiropractic Care:

  • Can support spinal health and potentially improve nervous system function, which may indirectly benefit thyroid health.

• Homeopathy:

  • Some individuals may find relief with homeopathic remedies tailored to their specific symptoms and overall health.

• Essential Oils:

  • Oils like frankincense and myrrh may be used for their potential anti-inflammatory and hormone-balancing properties.
