When several nodules form in the thyroid, the condition is known as a multinodular goiter or enlarged thyroid. Thyroid enlargement can cause difficulty in breathing and eating.

Multinodular goiters are a common thyroid disorder, especially among older individuals and women.

What is a Multinodular Goiter?

The thyroid is a tiny, butterfly-shaped gland in your neck that helps regulate essential processes in your body, like metabolism. Sometimes, the thyroid can start growing for various reasons, forming these little bumps or nodules.

This unusual lump in or on the thyroid gland at the front of the neck are usually caused by the abnormal overgrowth of cells in the gland. Either solid or filled with fluid, there are different types of thyroid nodules:

  • Non cancerous Thyroid Nodules
  • Toxic Nodules (Hyperthyroidism)
  • Multinodular Goiter
  • Thyroid Cysts

A Multinodular Goiter is a thyroid gland that has grown larger than usual and developed several small, rounded bumps or nodules.

Thyroid Nodules

The Supreme Vascular and Interventional Clinic understands the concern and uncertainty surrounding thyroid nodules. If you’ve discovered a lump in your neck, we’re here to provide clarity, comprehensive care, and thyroid nodule treatments.

Multinodular Goiter Overview and Symptoms

The thyroid may enlarge and form nodules for various reasons. While it’s common among adults and older individuals, most nodules are harmless and don’t cause issues.

Multinodular Goiter may sound complex, but it’s pretty straightforward. Imagine it as an enlarged thyroid gland with multiple small bumps, or nodules, on it.

If nodules become too large or numerous, they impact the thyroid’s normal function. Symptoms like difficulty swallowing, breathing, or voice changes could arise. Consulting a healthcare professional is essential if these symptoms occur. Regular check-ups and prompt consultation with healthcare professionals ensure you can maintain your thyroid and overall health.

 

Who is Predisposed to Multinodular Goiters?

Multinodular Goiters aren’t uncommon, especially among adults and older individuals. Certain groups of individuals are more prone to developing Multinodular Goiter. Here’s a look at some factors contributing to this condition.

  • Age and Gender: Goiters most often occur in adults and become more prevalent with age. Women, especially those over 60, are more likely to develop nodules and multinodular goiters on their thyroid glands.
  • Geography: People living in regions with low iodine levels in the soil and water are at a higher risk of developing multinodular goiters.
  • Autoimmune Disorders: some people living with Hashimoto’s Thyroiditis are more likely to get goiters.
  • Family History: A family history of thyroid disorders, including multinodular goiters, can increase an individual’s susceptibility to developing the condition. Genetic factors may play a role.

Understanding these risk factors can help individuals and healthcare professionals identify potential vulnerabilities and take proactive measures. Learn more in detail in our interesting article, “The Thyroid Gland Function and Common Disorders”

Causes of Multinodular Goiter

There are several potential multinodular goiter causes, and often, a person may have several of these factors at play:

  • Iodine Deficiency: Insufficient iodine intake can contribute to the development of Multinodular Goiter. Since the thyroid relies on iodine to produce hormones, a lack of iodine can lead to gland enlargement and the formation of nodules.
  • Radiation Exposure: Exposure to radiation through medical treatments or environmental factors is another risk factor. Individuals who have undergone radiation therapy to the neck or chest area may be more prone to developing thyroid nodules.
  • Autoimmune Diseases: Certain autoimmune disorders, such as Hashimoto’s thyroiditis, increase the risk of goiters. With autoimmune disease, the body’s immune system mistakenly attacks the thyroid, leading to inflammation and potential nodule formation.

    Risk Factors of Multinodular Goiter

    Previously, we touched upon the causes of Multinodular Goiter, shedding light on factors such as iodine deficiency, age, genetic predisposition, autoimmune conditions, radiation exposure, and geographical influences.

    Insufficient iodine intake remains a prominent risk factor because it plays a crucial role in thyroid hormone production. Geographical factors, including low iodine levels in certain regions, can elevate the risk of goiters.

    Multinodular goiters also tend to become more prevalent with age, especially in women over 60. Genetic factors contribute to the likelihood of developing thyroid nodules. Autoimmune diseases like Hashimoto’s thyroiditis and exposure to radiation, whether through medical treatments or environmental sources, are all common causes.

     

    Diagnosis of Multinodular Goiter

    A combination of diagnostic tools allows your doctor to accurately diagnose Multinodular Goiters, assess their impact on thyroid function, and determine appropriate management strategies.

    Your physician will order multinodular goiter ultrasounds, CT scans, or other scans to get a view of the size of the goiter and any abnormalities. You and your specialist will then decide on the proper treatment for your diagnosis.

     

    Multinodular Goiter Treatment in Singapore

    Treatment for multinodular goiter includes several options, including medication, iodine supplements, thyroid hormone replacement, surgery, and radioactive iodine treatment.

    Medication can help control thyroid hormones and reduce nodule size, while iodine supplements may be a preferred treatment for a deficiency. Thyroid hormone replacement is prescribed if the thyroid isn’t producing enough hormones. This is the least invasive multinodular goiter treatment.

    For more severe cases, for example, goiters causing swallowing or breathing issues, there are surgical options. As NIH research recommends, larger nodules, such as those 4cm or larger, should be removed through thyroid nodule surgery. A doctor may remove the nodule or perform a biopsy to rule out cancers. Surgical resection and radiofrequency ablation are effective treatments of nodular goiter. RFA is a safe and minimally invasive treatment of benign thyroid nodules, even toxic ones. 

    Finally, radioactive iodine treatment involves taking a substance to shrink nodules.

    For people with co-occurring conditions, the choice of therapy depends on their overall health. Medications and thyroid hormone replacement can be suitable for those with certain conditions, while surgery or radioactive iodine might be carefully considered, taking into account any potential complications. Individuals must communicate openly with their doctors to determine the most appropriate treatment, considering their unique health situation.

    Always talk to a specialist about the best treatment for your specific situation. They can guide you to the most suitable path toward thyroid health.

    Multinodular Goiters and Cancer

    While most multinodular goiters are benign and non-cancerous, there is a small risk of malignancy within these nodules. Thyroid cancer can occur in one or more of the nodules, making it essential for individuals with multinodular goiters to undergo proper evaluation and monitoring.

    Multinodular goiters are a common thyroid disorder, especially among older individuals and women. According to additional research from the National Institutes of Health, “Single and multiple thyroid nodules are found in 5.3% of women, with an increased frequency in women over 45 years of age.” Cancerous nodules are also most common in women over the age of 60.

    The prognosis for people with multinodular goiters depends on the presence and type of thyroid cancer, if any. Papillary thyroid cancer is the most common cancer found in multinodular goiters, and most people have good outcomes with treatment.
    In cases where thyroid cancer is detected, surgical removal of the affected nodules or the entire thyroid gland may be recommended. Find out more on our informative blog post, “Types of Thyroid Nodules and Cancer”.

    Regular follow-up and monitoring, including periodic ultrasound examinations and thyroid function tests, are essential to detect any nodule changes and ensure timely intervention. A specialized thyroid nodule clinic should be a part of your treatment plan.
