Hyperthyroidism treatment

Overactive Thyroid (Hyperthyroidism)

An overactive thyroid, also known as hyperthyroidism or thyrotoxicosis, occurs when the thyroid gland produces too much thyroid hormone. This can lead to a range of symptoms and may require medical treatment.

What is the thyroid?

The thyroid is a small, butterfly-shaped gland located at the front of the neck, just in front of the windpipe (trachea). It produces hormones that regulate many important functions in the body, including your metabolism, heart rate, and body temperature.

When the thyroid becomes overactive, it releases too much of these hormones into the bloodstream, which can cause a number of symptoms and, in some cases, lead to more serious health problems.

Who is affected?

Hyperthyroidism can affect anyone, but it is around 10 times more common in women than in men. It most often develops between the ages of 20 and 40.

Symptoms of an Overactive Thyroid

An overactive thyroid can cause a wide range of symptoms, including:

  • Feeling anxious, nervous, or irritable
  • Mood swings
  • Difficulty sleeping
  • Persistent tiredness or muscle weakness
  • Sensitivity to heat
  • A swelling in the neck (goitre)
  • Irregular or rapid heartbeat (palpitations)
  • Shaking or trembling
  • Unexplained weight loss

Timely diagnosis and appropriate treatment can significantly reduce the risk of these complications.

If you’re experiencing symptoms or have concerns about your thyroid health, our specialists at Sulis Hospital are here to help.

If you think you may have symptoms of an overactive thyroid, you should seek medical advice.

A specialist will talk to you about your symptoms and may recommend a blood test to check your thyroid hormone levels. If your results suggest hyperthyroidism, further tests may be carried out to determine the underlying cause.

Hyperthyroidism is usually treatable, and there are several options available depending on your individual needs:

  • Medication – to reduce the amount of thyroid hormone your body produces
  • Radioiodine treatment – a targeted form of radiotherapy that reduces thyroid activity
  • Surgery – removal of part or all of the thyroid gland

Your treatment will be discussed in detail with an endocrinologist (a specialist in hormonal conditions), who will help determine the best approach for you.

There are several possible causes of an overactive thyroid, including:

  • Graves’ disease – an autoimmune condition and the most common cause
  • Thyroid nodules – lumps in the thyroid that produce excess hormones
  • Certain medications – such as amiodarone, used to treat irregular heart rhythms.

If left untreated, an overactive thyroid can lead to complications, including:

Eye problems – such as dry or bulging eyes and double vision

Pregnancy risks – including pre-eclampsia, premature birth, or miscarriage

Thyroid storm – a rare but serious condition where symptoms rapidly worsen and become life-threatening
