Overview
Your thyroid gland is a small, butterfly-shaped organ. It is found at the front of your neck, just below the voice box. The main purpose of the thyroid gland is to regulate metabolism, energy levels, and overall hormonal balance. It is part of your endocrine system, which creates and releases thyroid hormones into the bloodstream.
When the body needs more energy in certain situations—such as during cold weather or pregnancy—the thyroid gland produces more hormones. However, if it produces either too much hormone (hyperthyroidism) or too little hormone (hypothyroidism), it can lead to a condition called thyroid disease.
What is the Thyroid Gland?
The main purpose of the thyroid gland is to produce hormones that regulate metabolism, heart rate, body temperature, and protein synthesis. The thyroid gland produces two main hormones:- Thyroxine (T4): The primary hormone that influences metabolism and energy levels.
- Triiodothyronine (T3): A more active hormone that also affects metabolic processes.
What are the common thyroid disorders?
Primarily, there are two main types of thyroid disorders: hyperthyroidism (an overactive thyroid) and hypothyroidism (an underactive thyroid), each of which can be caused by various conditions.Hyperthyroidism
Hyperthyroidism is a condition in which the thyroid gland is overactive. Due to this, it produces too much thyroid hormone. This increases the body's metabolism and affects various body functions. This condition may lead to many symptoms, including:
- Muscle weakness
- Weight loss without trying
- Sweating
- Diarrhoea
- Nervousness
- Rapid heart rate
- Thinning skin and brittle hair
Hypothyroidism is quite the opposite of hyperthyroidism. This condition occurs when the thyroid gland doesn't produce enough hormones. It can cause some of the body's functions to slow down. Hypothyroidism can be caused by Hashimoto's thyroiditis, thyroid surgery, or damage from radiation treatment. This condition may lead to various symptoms, such as:
- Tiredness
- Increased sensitivity to cold
- Constipation
- Dry skin
- Weight gain
- Puffy face
- Hoarse voice
- Hashimoto’s Thyroiditis: This is an autoimmune disorder that can cause the thyroid gland to become inflamed, leading to goitre (neck swelling) and other symptoms.
- Thyroid Tumours: This condition occurs when a small, noncancerous growth in the thyroid gland, called a nodule or adenoma, develops. It can cause hyperthyroidism. Treatment often involves surgery to remove the overactive nodule.
- Thyroid Cancer: Thyroid cancer is more common in those who have had radiation to the head, neck, or chest, but it can also occur without risk factors. The four main types are papillary, follicular, anaplastic, and medullary. These cases are treatable.
How to Diagnose Thyroid Disorders
Your doctor can diagnose thyroid disease through physical examination, medical history, and blood tests. If thyroid disease is suspected, your doctor may recommend:Blood Tests:
- A blood test to measure thyroid-stimulating hormone (TSH).
- Low TSH levels can indicate a thyroid disorder.
- A blood test to measure T4 hormone.
- Measures anti-thyroid peroxidase (anti-TPO) antibodies.
- High levels of antibodies may indicate thyroid damage.
- High TSH levels could indicate hypothyroidism (underactive thyroid).
- Low TSH levels could indicate hyperthyroidism.
What are the treatment options for thyroid disorders?
Hypothyroidism- An underactive thyroid (hypothyroidism) is usually treated with daily hormone replacement tablets called levothyroxine. They are used to replace low hormone levels.
An overactive thyroid (hyperthyroidism) thyroid condition, where medication is used to reduce hormone production. Various medications are recommended by doctors :
- Antithyroid drugs (like methimazole) are used to reduce hormone production.
- Radioactive iodine: Destroys overactive thyroid cells.
- Surgery: Removal of part or all of the thyroid gland.
The treatment of thyroid nodules depends on the type of nodule and its symptoms.
- Monitoring: Regular ultrasound exams if nodules are benign.
- Biopsy: Fine needle aspiration for suspicious nodules.
- Surgery: If nodules are large or cancerous.
- Surgery: Removal of the thyroid gland (thyroidectomy).
- Radioactive Iodine Therapy: To destroy remaining cancerous cells.
- Thyroid Hormone Therapy: To suppress TSH and reduce cancer recurrence risk.
