Hyperthyroidism generally known as an overactive thyroid is a condition where the thyroid gland produces high amounts of thyroid hormones. This affects nearly every bodily system because thyroid hormones play a crucial role in metabolism. 

Approximately 2 in 100 Indians experience this condition with women being more prone than men. Hyperthyroid Tests are necessary in the early stages to ensure safe treatment for the potential dangers.

What is Hyperthyroidism?

Hyperthyroidism occurs when the thyroid gland located in the neck fails to follow the normal feedback mechanism that regulates hormone production. Normally, the hypothalamus and pituitary gland work together to control thyroid hormone levels through the Hypothalamic Pituitary Thyroid (HPT) axis. This feedback loop ensures that the body maintains optimal levels of thyroid hormones.

The process begins with the hypothalamus releasing Thyroid-Releasing Hormone (TRH) when it needs more thyroid hormones are needed. TRH then stimulates the pituitary gland to release Thyroid Stimulating Hormone (TSH), which in turn prompts the thyroid gland to produce thyroxine (T4) and triiodothyronine (T3). Most of the hormones produced are T4 but T3 is more metabolically active among all. Therefore, T4 is converted into T3 in peripheral tissues, such as the liver and kidneys.

When there are sufficient levels of T4 and T3 in the bloodstream in a healthy thyroid gland the hypothalamus and pituitary gland reduce the production of TRH and TSH respectively. 

This decrease in TSH signaling leads to a reduction in thyroid hormone production, maintaining a balance. Get an Affordable Hyperthyroid Test Price to check whether the thyroid gland continues to produce high levels of T4 and T3 despite low levels of TSH disturbing this delicate balance.

Symptoms of Hyperthyroidism

The symptoms of hyperthyroidism are diverse and widespread due to the involvement of multiple body systems. If found severe, it is advised to opt for the Hyperthyroid Test.

Cardiovascular Symptoms:

  • Rapid heartbeat (tachycardia)
  • Heart palpitations
  • Increased risk of atrial fibrillation, a heart rhythm disorder that can lead to stroke

Metabolic Symptoms:

  • Excessive sweating
  • Unintended weight loss despite increased appetite
  • Increased hunger

Neurological Symptoms:

  • Irritability
  • Anxiety
  • Nervousness
  • Sleeplessness

Musculoskeletal Symptoms:

  • Fatigue
  • Muscle weakness

Dermatological Symptoms:

  • Thinning skin
  • Brittle hair and nails

Reproductive Symptoms:

  • Menstrual irregularities
  • Infertility

Gastrointestinal Symptoms:

  • Frequent bowel movements

Other Symptoms:

  • Goiter (enlargement of the thyroid gland)
  • Tremors

Complications of Hyperthyroidism

Hyperthyroidism can lead to several complications affecting various body systems:

Cardiac Considerations

Hyperthyroidism may contribute to atrial fibrillation, a heart rhythm disorder. This condition increases the risk of stroke. Additionally, congestive heart failure, where the heart does not pump enough blood and oxygen throughout the body, is also a concern.

Skeletal Considerations

Hyperthyroidism can lead to difficulty transporting calcium into the bones, potentially increasing the risk of osteoporosis. This is particularly concerning for older adults, as it can lead to fractures and mobility issues.

Vision Considerations

Thyroid eye disease occurs when the muscles and tissues surrounding the eye receive too many thyroid hormones. This condition is more common in smokers and can cause bulging of the eyes, redness, retracted or inflamed eyelids, double vision, light sensitivity, and painful pressure in the eye.

Skin Considerations

Dermopathy usually occurs on the shins and feet and is characterized by a color change and swelling.

Thyrotoxic Crisis

Hyperthyroidism may also raise the risk of a thyrotoxic crisis, also known as a thyroid storm. This is a serious condition that requires immediate medical attention. Symptoms include rapid heartbeat, confusion and delirium, nausea, vomiting, fever, and dehydration.

Diagnosis of Hyperthyroidism

Diagnosing hyperthyroidism involves a combination of medical history, physical examination, and blood tests.

Medical History and Physical Examination

During the examination, healthcare providers may check for:

  • Slight tremor in fingers and hands
  • Overactive reflexes
  • Rapid or irregular pulse
  • Eye changes
  • Warm, moist skin
  • Enlargement or tenderness of the thyroid gland

Blood Tests

Hyperthyroid Test measures the levels of T4, T3, and TSH. A high level of T4 and a low level of TSH are common in people with hyperthyroidism. These tests are particularly important for older adults, as they may not exhibit classic symptoms of hyperthyroidism.

It's crucial to note that thyroid blood tests can give false results if you are taking biotin, a B vitamin supplement often found in multivitamins. Inform your healthcare provider if you are taking biotin or a multivitamin containing biotin. To ensure accurate test results, you may be asked to stop taking biotin 3 to 5 days before the test.

Additional Diagnostic Tests

If Hyperthyroid Test results indicate hyperthyroidism, your healthcare provider may suggest additional tests to determine the underlying cause:

  1. Radioiodine Scan and Uptake Test: This involves ingesting a small dose of radioactive iodine to see how much of it collects in the thyroid gland and where it collects. A high uptake suggests that the thyroid gland is overproducing hormones, often due to Graves' disease or overactive thyroid nodules. A low uptake may indicate thyroiditis, where stored hormones are leaking into the bloodstream.
  2. Thyroid Ultrasound: This test uses high-frequency sound waves to create images of the thyroid. It is effective for detecting thyroid nodules and does not involve radiation, making it suitable for pregnant or breastfeeding individuals.

Management and Treatment of Hyperthyroidism

  1. Medications: Thionamides, such as carbimazole and propylthiouracil, are used to reduce thyroid hormone production. Beta-blockers may be prescribed to manage symptoms like rapid heartbeat.
  2. Radioactive Iodine Treatment: This involves ingesting radioactive iodine to reduce thyroid hormone production. It is highly effective but requires precautions post-treatment, such as avoiding close contact with others, especially children and pregnant women, for a short period.
  3. Surgery: In some cases, surgery may be necessary to remove part or all of the thyroid gland. This requires lifelong thyroid hormone replacement therapy to maintain normal hormone levels.

Supportive Approaches

In addition to conventional treatments, supportive approaches can aid in symptom relief and improve quality of life:

  • Dietary Changes: Eating a balanced diet rich in fruits, vegetables, and whole grains can help manage symptoms.
  • Stress Management: Techniques like meditation and yoga can reduce stress, which may exacerbate symptoms.
  • Regular Exercise: Gentle exercise can help maintain physical health without exacerbating fatigue.
