Goitre

Overview

A goitre is an enlargement of the thyroid gland, which is a small butterfly-shaped gland in the front of your neck. The thyroid makes hormones that help control your body's energy use. When it gets bigger, it can form a lump or swelling in your neck.

Yes, goitres are fairly common around the world. In areas where iodine is added to salt, they are less common but still occur, especially in women and people over 40.

Goitres can affect anyone, but they are more common in women, people over 40, and those with a family history of thyroid problems. People with certain autoimmune diseases or who live in iodine-deficient regions are also at higher risk.

Symptoms

Common symptoms

• Visible swelling at the base of the neck
• A feeling of fullness or pressure in the throat
• Difficulty swallowing or a sensation of a lump in the throat
• Hoarseness or coughing
• Tightness in the neck area

Symptoms in children

• A noticeable lump or swelling in the neck
• Breathing difficulties if the goitre is large
• Problems feeding or swallowing in infants

Symptoms in older adults

• Same swelling as in younger adults, but may be more pronounced
• Difficulty swallowing or breathing due to pressure from the enlarged gland
• Increased likelihood of the goitre affecting thyroid function (overactive or underactive)

Causes

Main causes

• Iodine deficiency: Not getting enough iodine in your diet can cause the thyroid to enlarge.
• Autoimmune disease: The immune system attacking the thyroid (e.g., Hashimoto's disease or Graves' disease) can cause swelling.
• Thyroid nodules: Lumps that form inside the thyroid can make the whole gland bigger.

Risk factors

• Being female
• Being over 40 years old
• Having a family history of goitre or thyroid conditions
• Living in an area with low iodine in the soil (such as some mountainous regions)
• Having an autoimmune disease like type 1 diabetes or rheumatoid arthritis

When to see a doctor

See a doctor urgently if:

• If you have sudden trouble breathing or swallowing
• If you have severe pain or swelling in your neck

Book a routine appointment if:

• If you notice a new or growing lump in your neck
• If you have symptoms like a feeling of fullness, hoarseness, or mild swallowing difficulty
• If you have other thyroid symptoms like weight changes, fatigue, or mood swings

Diagnosis

Your doctor will examine your neck and ask about your symptoms and medical history. They will feel the thyroid gland and may check for any lumps. To confirm a goitre and find the cause, they will usually order some tests.

Tests that may be done

• Blood tests to check thyroid hormone levels (TSH, T3, T4) and antibodies for autoimmune conditions
• Ultrasound scan of the neck to see the size and structure of the thyroid and look for nodules
• A radioactive iodine uptake test or thyroid scan to check how well the thyroid is working

What to expect at your appointment

The tests are usually painless. An ultrasound is a gentle scan using sound waves – you just lie down while a small device is moved over your neck. Blood tests are taken from your arm. Results often come back in a few days, and your doctor will explain what they mean.

Treatment

Treatment depends on the size of the goitre, your symptoms, and whether your thyroid function is normal. Many small goitres need no treatment other than monitoring. If the goitre is causing symptoms or if your thyroid is overactive or underactive, your doctor will suggest a treatment plan.

Self-care at home

• If you have an iodine deficiency, your doctor may suggest increasing iodine in your diet (e.g., using iodized salt, eating seafood, but always follow medical advice).
• Avoid taking supplements containing high doses of iodine without checking with your doctor, as too much can make things worse.
• If you smoke, consider stopping, as smoking can make goitres more likely.
• Eat a balanced diet with enough fruits, vegetables, and whole grains.

Medical treatments

If your thyroid is underactive (hypothyroidism), your doctor may prescribe thyroid hormone replacement therapy to bring hormone levels back to normal. If it is overactive (hyperthyroidism), treatments may include medicines that reduce hormone production, radioactive iodine therapy to shrink the thyroid, or beta-blockers to control symptoms like rapid heartbeat. The exact choice depends on your specific situation.

When is surgery considered?

Surgery to remove part or all of the thyroid may be recommended if the goitre is very large, causing breathing or swallowing problems, or if it contains suspicious nodules that could be cancerous.

Living with this condition

Living with a goitre often requires little to no change in your daily life, especially if it is small and not causing symptoms. You may need regular check-ups with your doctor to monitor the goitre's size and your thyroid function.

Lifestyle tips

• Wear comfortable clothing that does not put pressure on your neck.
• If you have a visible swelling, you may choose to wear scarves or collars if it makes you feel more comfortable.
• Get regular exercise to maintain overall health and energy levels.
• Manage stress through relaxation techniques like deep breathing or meditation.

Diet and exercise

A balanced diet with adequate iodine (not too much, not too little) is important. Talk to your doctor about your specific needs. Staying active with moderate exercise can help you feel better overall, but no special diet or exercise is proven to shrink a goitre.

Mental health and emotional wellbeing

Having a visible lump on your neck can affect your self-esteem or cause anxiety about health. It is normal to feel concerned. Talking to a trusted friend, family member, or a counsellor can help. Remember that most goitres are not dangerous.

Prevention

In areas where goitre is caused by iodine deficiency, using iodized salt and eating iodine-rich foods like fish, dairy, and eggs can help prevent it. For autoimmune causes, there is no known way to prevent them. Regular check-ups can help catch goitres early.

Complications

If left untreated

• The goitre may grow larger and press on the windpipe or food pipe, causing breathing or swallowing difficulties.
• Thyroid function may become abnormal (overactive or underactive), leading to symptoms like weight changes, heart problems, or fatigue.
• In rare cases, nodules within a goitre can become cancerous, though most are benign.

Long-term outlook

With proper medical care, most goitres can be managed well. Many people live with a small goitre for years without any problems. Even when treatment is needed, outcomes are usually excellent. Surgery or medication can effectively control symptoms, and regular monitoring ensures any changes are caught early. Your healthcare team will guide you through the best options for your situation.
