Understanding the thyroid: function, imbalances and natural support
What is the thyroid and how does it work?
The thyroid is a small, butterfly-shaped gland located at the base of the neck. Despite its size, it plays a crucial role in regulating metabolism, energy production and overall hormonal balance.
The thyroid produces two key hormones: thyroxine (T4) and triiodothyronine (T3), which influence almost every cell in the body. T4 and T3 are regulated by the pituitary gland, which releases thyroid-stimulating hormone (TSH) to help maintain balance.
How thyroid imbalances affect health
When the thyroid is not functioning properly, it can lead to significant health issues. There are two primary types of thyroid dysfunction: hypothyroidism and hyperthyroidism.
Hypothyroidism (underactive thyroid) is commonly caused by Hashimoto’s thyroiditis, an inflammatory autoimmune condition where the body mistakenly attacks the thyroid and occurs when the thyroid does not produce enough hormones, leading to slow metabolism.
Symptoms include:
Fatigue and low energy
Weight gain and difficulty losing weight
Dry skin and hair loss
Depression or mood changes
Cold intolerance
Brain fog and memory issues
Hyperthyroidism (overactive thyroid) is commonly caused by Grave’s disease, another autoimmune condition, and results from excessive thyroid hormone production, speeding up metabolism.
Symptoms include:
Unexplained weight loss
Anxiety and nervousness
Rapid heartbeat or palpitations
Insomnia
Excessive sweating
Heat intolerance
Who is affected by thyroid imbalances?
Thyroid imbalances can impact anyone, but some groups are at higher risk:
Women are significantly more likely to experience thyroid disorders, particularly during pregnancy, postpartum, and menopause where those big hormonal shifts occur.
Thyroid function naturally changes with age, making older adults more susceptible
Those with other auto immune conditions i.e. lupus, coeliac disease are more prone to thyroid dysfunction
Individuals with nutritional deficiencies including iodine, selenium, zinc plus a number of others
Prolonged stress can impact hormone regulation, including thyroid function
How to support and balance thyroid function naturally
Fortunately, there are several ways to support thyroid health through lifestyle and dietary choices.
Nutrients
Iodine: found in seaweed, fish and dairy. Iodine is an essential component of T4 and T3
Selenium: Brazil nuts, sunflower seeds and tuna. Protects the thyroid from oxidative stress and plays a role in converting T4 to T3
Zinc: shellfish, beef and pumpkin seeds. Supports immune function and hormone production
Stress management
Prolonged stress increases cortisol levels which can interfere with thyroid hormone conversion. Regular exercise, deep breathing and meditation can help to reduce stress
Supporting gut health
Maintaining a healthy balanced gut microbiome aids in nutrient absorption and immune regulation. Fibre-rich foods and probiotics support gut health and in turn thyroid function
Avoiding toxins
Endocrine (hormone) disruptors found in plastics, processed foods and household products can impact thyroid function. Selecting organic foods and using natural cleaning products when possible can reduce toxin exposure
Regular thyroid testing
Since symptoms of thyroid dysfunction can overlap with other conditions, regular blood tests (TSH, T3, T4,and thyroid antibodies) can provide a clearer picture of thyroid health
The thyroid plays a vital role in maintaining overall health and wellbeing, and when out of balance, can lead to a range of symptoms affecting energy levels, weight, mood and metabolism.
