THYROID DISORDERS

38

Have you ever wondered what your thyroid actually does? Well, this small but mighty gland plays a crucial role in your body’s metabolic processes by producing hormones that regulate various functions. Situated at the front of your neck, just below the skin, your thyroid is shaped like a butterfly and is a vital part of your endocrine system. Thyroid disease, also known as thyroid disorders, occurs when your thyroid gland produces either too much or too little of these important hormones. This condition can vary from a harmless enlarged gland called a goiter, which may require no treatment, to more severe issues such as life-threatening cancer.

What Happens When Your Thyroid Goes Off Track?

Trouble arises when your thyroid produces too much or too little hormone. This imbalance is called thyroid disease, and it can affect people of all ages.

The two main types of thyroid disorders are:

• Hyperthyroidism: When your thyroid makes too much hormone, your body goes into overdrive. This can lead to symptoms like anxiety, weight loss, rapid heartbeat, and bulging eyes. Hyperthyroidism occurs due to overproduction of thyroid hormones and can manifest in various ways:
  • Graves’ disease: This condition involves the thyroid gland producing an excess amount of hormone.
  • Toxic adenomas: Nodules develop in the thyroid gland, disrupting the body’s chemical balance by overproducing thyroid hormones.
  • Subacute thyroiditis: Inflammation of the thyroid causes excess hormone secretion, leading to temporary hyperthyroidism.
  • Pituitary gland malfunctions or thyroid cancerous growths: Rarely, these can also cause hyperthyroidism.
• Hypothyroidism: When your thyroid doesn’t produce enough hormone, your body slows down. Symptoms can include fatigue, weight gain, depression, and feeling cold all the time. Causes of hypothyroidism include:
  • Hashimoto’s thyroiditis is an autoimmune disorder where the body attacks thyroid tissue, leading to hormone deficiency.
  • Postpartum thyroiditis: Occurring after childbirth, miscarriage, or abortion, it’s usually temporary.
  • Iodine deficiency: Since iodine is essential for hormone production, its deficiency can cause hypothyroidism.
  • Surgical removal of the thyroid gland: in cases of thyroidectomy or chemical destruction.
  • Excessive iodine exposure: Certain medications or contrast dyes may lead to hypothyroidism.
  • Previous thyroid issues or lithium usage: These factors can also contribute to hypothyroidism.

If left untreated, hypothyroidism can lead to severe complications such as myxedema and coma, which are particularly risky for newborns and infants, potentially causing intellectual disabilities and stunted growth.

While thyroid cancer is rare, it can develop in about 5% of thyroid nodules. Individuals who have undergone radiation treatment to the head and neck, possibly for acne, may have a higher risk of thyroid cancer. Regular monitoring and early intervention are crucial in managing thyroid disorders effectively.

Diagnosing thyroid disorders

Diagnosing thyroid disease can be challenging because its symptoms often resemble those of other conditions. To accurately identify thyroid issues, your doctor may perform various tests:

1. Blood tests: These are one of the most reliable methods for diagnosing thyroid problems. By analyzing the levels of thyroid hormones in your blood, your doctor can assess thyroid function. Blood samples are typically taken from a vein in your arm.
2. Imaging tests: Your doctor may recommend imaging tests, such as a thyroid scan or ultrasound, to examine the thyroid gland. These tests help detect any abnormalities in the size, shape, or presence of nodules or growths within the thyroid.
3. Physical exams: During a routine physical examination, your doctor may gently feel your neck to check for any noticeable growths or enlargements of the thyroid gland. This simple and painless procedure can provide valuable insights into thyroid health.
4. Iodine uptake tests: If hypothyroidism is suspected, your doctor may perform an iodine uptake test to determine the underlying cause. This test tracks the amount of iodine absorbed by the thyroid gland, as iodine is essential for thyroid hormone production.

Additionally, you can perform a basic self-assessment at home to check for any signs of thyroid abnormalities:

1. Grab a mirror and a glass of water.
2. Locate your thyroid gland on the front of your neck, between your collarbone and Adam’s apple.
3. Tilt your head back and take a sip of water while observing your thyroid gland in the mirror.
4. Pay attention to any lumps or bumps that may appear as you swallow.
5. Repeat this process a few times, looking for any consistent abnormalities.
6. If you notice any unusual lumps or bumps, it’s essential to contact your doctor for further evaluation and guidance.

By being aware of the symptoms and risk factors associated with thyroid disease and undergoing appropriate diagnostic tests, you can take proactive steps to manage your thyroid health effectively.

Treatment Options: Getting Back on Track

Treating thyroid disease involves various approaches tailored to the specific type and underlying cause of the condition. Here’s a breakdown of treatment options:

1. Subacute Thyroiditis Treatment:
   • Subacute thyroiditis typically resolves on its own without medical intervention.
   • Over-the-counter pain relievers like acetaminophen or aspirin can help alleviate discomfort. However, aspirin should be avoided in children due to the risk of Reye’s syndrome.
   • If pain persists, anti-inflammatory drugs such as dexamethasone or prednisone may be prescribed for a short period of time.
2. Hyperthyroidism Treatment:
   • Radioactive iodine treatment, antithyroid medication, or surgery are common approaches.
   • Radioactive iodine treatment involves ingesting a tablet or liquid containing radioactive iodine, which damages thyroid cells and reduces hormone production. Multiple treatments may be necessary, but hypothyroidism may develop as a result.
   • Antithyroid medications typically alleviate symptoms within 6–8 weeks and may need to be continued for about a year before reassessment. Regular checkups are essential post-medication cessation.
   • Surgery is reserved for specific cases such as pregnancy, large goiters, or cancerous nodules.
3. Hypothyroidism Treatment:
   • Hypothyroidism requires lifelong thyroid hormone replacement therapy.
   • Synthetic thyroid hormones, like levothyroxine, are commonly prescribed. Adjustments to the dosage may be necessary to manage side effects like nervousness or chest pain, which are rare.
   • It’s crucial to inform your doctor of all medications and supplements being taken, as some may affect thyroid hormone absorption or efficacy.
4. Thyroid Cancer Treatment:
   • Thyroid cancer treatment typically involves surgical removal of the cancerous tissue or the entire thyroid gland (thyroidectomy).
   • If cancer has spread, additional affected tissues, such as lymph glands in the neck, may also be removed.

Healthcare providers will carefully weigh the benefits and risks of each treatment option alongside you, tailoring the decision to your unique circumstances. By understanding the available treatments and actively participating in the decision-making process, individuals can effectively manage thyroid disease and optimize their overall health and well-being.

Alternative Treatment and Thyroid Diet: Exploring Options

While conventional medical treatments are often effective in managing thyroid problems, some individuals may seek alternative therapies to complement their treatment. It’s essential to discuss these options with your doctor to ensure they are safe and compatible with your current treatment plan.

1. Naturopathic Approaches:
   • Naturopaths may utilize homeopathic remedies, herbal supplements, traditional Chinese medicine, and acupuncture to address thyroid issues. Scientific studies haven’t found strong evidence that these therapies directly treat thyroid disorders, although they might help manage stress linked to the condition
   • Naturopathic treatments may be legal in some states but illegal in others. It’s important to verify the qualifications and licensure of any practitioner offering these services.
2. Chiropractic Care:
   • Chiropractors may use spinal manipulation techniques to relieve the symptoms of thyroid disorders by reducing muscle tension and enhancing blood circulation. While chiropractic care can offer symptom relief, its direct impact on thyroid function is limited.
3. Thyroid Diet:
   • A balanced diet rich in protein, calcium, magnesium, iodine, B vitamins, vitamin A, and vitamin C can support thyroid health.
   • Iodine deficiency can contribute to thyroid dysfunction, so ensuring adequate iodine intake is crucial. However, excessive selenium supplementation in iodine-deficient individuals can lead to hypothyroidism, so it’s essential to consult with a healthcare provider before starting any supplements.
   • Certain substances, like pseudoephedrine (found in cold remedies) and alkaloids (including caffeine), may exacerbate thyroid symptoms and should be avoided.

Note:

It’s important to note that while these alternative therapies and dietary adjustments may offer symptom relief and support overall health, they should not replace conventional medical treatments prescribed by a healthcare professional. Regular monitoring and communication with your doctor are essential for managing thyroid disease effectively and preventing complications.

Thyroid disease can vary in severity, from harmless goiters to life-threatening conditions like thyroid cancer. Seeking prompt medical attention and adhering to prescribed treatments can help prevent complications and promote overall well-being. If you experience symptoms of thyroid disease or have concerns about your thyroid health, consult with your healthcare provider for personalized evaluation and management.
