The human neck, though often overlooked, houses an important gland that controls many of our body’s vital functions—the thyroid. The thyroid gland is located at the front of the neck and plays a key role in regulating metabolism, heart rate, and body temperature. When the thyroid swells or develops abnormal lumps, goiters, and thyroid nodules are among the most common culprits. While these two issues may seem similar, they are quite different in terms of causes, risk factors, and treatment options.
Here’s a closer look at neck goiters and thyroid nodules, their causes, and the available treatment options. We’ll also discuss when it’s time to see an endocrinologist in West Hills for evaluation.
What Is a Goiter?
A goiter is an abnormal enlargement of the thyroid gland. The thyroid may swell to the point where it becomes visibly noticeable, creating a bulge at the front of the neck. It is also common for a goiter to be present without being obvious. There are several reasons a goiter develops. Not all causes are indicative of thyroid dysfunction. Goiters can be present in people with both underactive (hypothyroid) and overactive (hyperthyroid) thyroids, as well as in people with normal thyroid function (euthyroid).
What Causes Goiters?
Goiters can develop due to a variety of reasons. Some of the most common causes include:
- Iodine Deficiency: One of the most common global causes of goiters is a lack of iodine in the diet. Iodine is an essential nutrient that helps the thyroid produce hormones. When there’s not enough iodine, the thyroid swells to compensate and produce adequate hormone levels.
- Graves’ Disease: This autoimmune condition causes the thyroid to become overactive, leading to hyperthyroidism. The thyroid grows as it works overtime to produce excess thyroid hormones, which can result in a goiter.
- Hashimoto’s Thyroiditis: Another autoimmune disease, Hashimoto’s thyroiditis, is a leading cause of hypothyroidism (underactive thyroid). In this condition, the immune system mistakenly attacks the thyroid, causing inflammation and swelling that can lead to goiter formation.
- Thyroid Nodules: Sometimes, multiple small lumps (nodules) can form in the thyroid and cause the gland to enlarge, resulting in a condition called multinodular goiter.
- Pregnancy: During pregnancy, the body increases its production of certain hormones, which can cause the thyroid gland to enlarge.
Regardless of the cause, it’s imperative to see an endocrinologist in West Hills for a proper evaluation and treatment.
What Is a Thyroid Nodule?
A thyroid nodule is a solid or fluid-filled lump that forms within the thyroid gland. Nodules are usually detected during routine physical exams, medical imaging, or when the individual notices a lump in their neck. Most thyroid nodules are benign (non-cancerous). Still, in some cases, they can be cancerous, so it’s essential to see an endocrinologist in West Hills to monitor and evaluate them carefully.
Causes of Thyroid Nodules
- Iodine Deficiency: Just like with goiters, a lack of iodine in the diet can cause the thyroid to produce nodules as it tries to compensate for low hormone production.
- Overgrowth of Thyroid Tissue: Sometimes, the thyroid tissue itself can grow more than usual, forming a nodule. This is often benign and doesn’t typically lead to health problems unless the nodule becomes too large.
- Thyroid Cysts: Some thyroid nodules are filled with fluid or blood rather than solid tissue. These are known as thyroid cysts, and while they’re usually non-cancerous, they can sometimes become quite large and require treatment.
- Inflammation: Conditions that cause thyroid inflammation, such as Hashimoto’s thyroiditis or subacute thyroiditis, can lead to the development of nodules.
- Thyroid Cancer: Although rare, thyroid cancer can present as a nodule in the thyroid. This is why having any nodule evaluated by an endocrinologist in West Hills is essential, especially if it is growing rapidly or causing symptoms.

Key Differences Between Goiters and Thyroid Nodules
Although both goiters and thyroid nodules involve abnormalities in the thyroid gland, there are some key differences between them:
- Size and Shape: A goiter involves the entire thyroid gland becoming enlarged, while thyroid nodules are localized lumps within the gland.
- Causes: Goiters are often caused by iodine deficiency, autoimmune diseases, or pregnancy, whereas thyroid nodules can develop due to tissue overgrowth, cysts, or cancer.
- Function: A goiter doesn’t always indicate a change in thyroid function, but some nodules can affect the thyroid’s ability to produce hormones, leading to either hyperthyroidism or hypothyroidism.
Risk Factors for Goiters and Thyroid Nodules
Several risk factors can increase the likelihood of developing a goiter or thyroid nodule. These include:
- Age: Thyroid nodules and goiters are more common in older adults.
- Gender: Women are more likely to develop thyroid-related conditions than men.
- Family History: A family history of thyroid problems can increase the risk of developing either a goiter or thyroid nodules.
- Radiation Exposure: Radiation treatments to the head, neck, or chest, especially during childhood, increase the risk of thyroid nodules and goiters.
- Iodine Deficiency: Living in an area where iodine is deficient in the diet increases the risk of developing both goiters and nodules.
Diagnosis and Evaluation
If you notice a lump in your neck or experience symptoms like difficulty swallowing or breathing, it’s important to consult an endocrinologist in West Hills. Testing is necessary to determine thyroid health and function.
- Physical Exam: The doctor will feel your neck for any enlargements or lumps in the thyroid.
- Blood Tests: These tests measure the levels of thyroid hormones (T3 and T4) and thyroid-stimulating hormone (TSH) in the blood to determine how well the thyroid is functioning.
- Ultrasound: An ultrasound uses sound waves to create images of the thyroid, allowing the doctor to see if there are any nodules, cysts, or abnormalities.
- Biopsy: If a nodule appears suspicious, a fine-needle aspiration biopsy may be performed to collect a small sample of tissue for further testing.
Treatment Options
Treatment for goiters and thyroid nodules depends on the underlying cause and severity of the condition.
Goiter Treatment
- Iodine Supplementation: In cases of iodine deficiency, increasing iodine intake can help shrink the goiter. This can be done through diet (iodized salt, seafood, dairy) or supplements.
- Medications: If the goiter is caused by hypothyroidism or hyperthyroidism, medications can help regulate thyroid hormone levels and reduce the size of the goiter.
- Surgery: In cases where the goiter is very large and causing difficulty breathing or swallowing, surgery may be necessary to remove part or all of the thyroid gland.
Thyroid Nodule Treatment
- Observation: If the nodule is small and benign, the doctor may recommend regular monitoring to ensure it doesn’t grow or cause problems.
- Radioactive Iodine: In some cases, radioactive iodine can be used to shrink thyroid nodules.
- Surgery: If a nodule is cancerous or causing symptoms, surgery to remove part or all of the thyroid may be recommended.

When to See a Doctor
It’s important to seek medical attention from an endocrinologist in West Hills if you notice a lump in your neck, experience difficulty swallowing or breathing, or develop symptoms of thyroid dysfunction, such as weight changes, fatigue, or changes in heart rate. Early detection and proper treatment can help manage both goiters and thyroid nodules and prevent complications.
Conclusion
Goiters and thyroid nodules are common conditions that affect the thyroid gland in different ways. Understanding the causes, risk factors, and treatment options can help you make informed decisions about your thyroid health. If you suspect you have a goiter or thyroid nodule, contact C/V ENT Surgical Group for an appointment with an endocrinologist in Encino and West Hills for proper diagnosis and care.
