The thyroid gland is a small butterfly-shaped organ located at the base of the neck which plays a crucial role in maintaining overall health. This vital gland produces hormones that regulate metabolism, growth, energy production, and many essential body functions. The health of your thyroid gland is integral to how your body functions daily.
Key Thyroid Hormones
The thyroid gland produces several essential hormones that regulate numerous bodily processes:
- Thyroxine (T4): The primary hormone, T4, controls your metabolism and energy levels.
- Triiodothyronine (T3): T3 is the active form of thyroid hormone that affects almost every physiological process in your body.
- Calcitonin: Regulates calcium levels, promoting bone health and aiding in calcium absorption.
- Reverse T3 (rT3): An inactive form of T3 that regulates the balance of active thyroid hormones.
The Role of TRH & TSH
The thyroid gland’s activity is regulated by two key hormones: thyrotropin-releasing hormone (TRH) and thyroid-stimulating hormone (TSH). TRH is produced in the hypothalamus, which signals the pituitary gland to release TSH. TSH then stimulates the thyroid gland to produce the thyroid hormones, T3 and T4, which regulate metabolism. When thyroid hormone levels drop, TRH and TSH production increase to boost hormone release, while high levels suppress their production. Maintaining balanced TSH levels is critical for proper thyroid function and overall metabolic health.
Thyroid Disorders: Hypothyroidism and Hyperthyroidism
Hypothyroidism
Hypothyroidism occurs when the thyroid gland fails to produce enough hormones, resulting in a slower metabolism. In India, an estimated 10-15% of the population suffers from this condition, with iodine deficiency and autoimmune disorders like Hashimoto’s thyroiditis being the most common causes. Hashimoto’s occurs when the immune system mistakenly attacks the thyroid gland, impairing its function. The symptoms can vary from persistent fatigue, weight gain, depression, and dry skin to more severe signs like muscle weakness, hair loss, and cold intolerance.
In addition to these symptoms, untreated hypothyroidism can lead to more serious complications such as heart disease, high cholesterol, and infertility. Early detection is essential and is typically done through blood tests that measure TSH and free T4 levels. Lifestyle adjustments such as consuming iodine-rich foods, managing stress, and maintaining a balanced diet play a key role in supporting thyroid health and managing the symptoms of hypothyroidism effectively.
Hyperthyroidism
Hyperthyroidism occurs when the thyroid gland overproduces hormones, leading to an accelerated metabolism throughout the body. This condition affects approximately 1-2% of the Indian population and is often associated with Graves' disease or toxic nodular goitre. Graves' disease is an autoimmune disorder where the immune system mistakenly stimulates the thyroid to produce excess hormones, while toxic nodular goitre involves the growth of thyroid nodules that secrete excess hormones.
Common symptoms of hyperthyroidism include unexplained weight loss, heightened anxiety, rapid heartbeat, and excessive sweating. If not addressed, hyperthyroidism can have severe long-term consequences, including heart disease, such as atrial fibrillation, which can increase the risk of stroke. It can also lead to osteoporosis, where bones become brittle and more prone to fractures, and muscle weakness, which can impact mobility and daily functioning. Additionally, untreated hyperthyroidism can result in a thyroid storm, a rare but critical condition characterised by a sudden and extreme exacerbation of symptoms, potentially leading to fever, confusion, and even heart failure.
Both hypo- and hyperthyroidism significantly impact overall well-being and require continuous management to mitigate risks and maintain quality of life.
Triggers and Risk Factors for Thyroid Disorders
Ageing: The risk of thyroid dysfunction increases with age, affecting 5-10% of adults over 60 in India due to decreased iodine intake and rising autoimmune disorders. Regular thyroid monitoring in older adults is crucial.
Menopause: Menopause can impact thyroid function, particularly in women with autoimmune conditions, with symptoms like hot flashes often overlapping with thyroid imbalance, complicating diagnosis.
Pregnancy: Up to 10% of Indian women experience hypothyroidism during pregnancy, making adequate iodine intake vital for preventing complications and supporting fetal development, with a recommended daily intake of 250 mcg.
Environmental Factors: Excessive iodine, infections, stress, and certain medications can trigger thyroid dysfunction, with excessive iodine intake from iodised salt or supplements potentially leading to hypo- or hyperthyroidism. Managing these environmental factors is essential for thyroid health.
Managing Thyroid Health
Maintaining thyroid health requires attention to several areas of your lifestyle:
- Balanced Diet: Ensure a diet rich in iodine (iodised salt, dairy, seaweed), selenium, and zinc. Avoid excess iodine.
- Physical Activity: Regular exercise supports metabolism and overall health.
- Quality Sleep: Prioritise 7-9 hours of restful sleep to support hormone regulation.
- Stress Management: Practice mindfulness, meditation, or other stress-relief techniques to keep cortisol levels in check, as high stress can disrupt thyroid function.
- Routine Check-ups: Regular thyroid function tests help in early detection and management of imbalances.
