Thyroid Nodules
Thyroid nodules are discrete lesions within the thyroid gland that are detectable by ultrasound. They are extremely common — found in up to 67% of adults on ultrasound. The vast majority are benign. The primary clinical task is identifying the minority that require biopsy or active intervention based on size, ultrasound characteristics, and clinical context.
When to Book
Book a visit if symptoms are new, persistent, getting worse, or affecting daily life. Early evaluation often prevents complications.
Symptoms
Most nodules are asymptomatic and found incidentally on imaging done for other reasons. Larger nodules may cause a visible lump in the neck, a sensation of pressure or fullness, difficulty swallowing, or hoarseness if they compress surrounding structures.
Causes & Risk Factors
Iodine deficiency, radiation exposure to the head and neck, family history of thyroid cancer, and autoimmune thyroid disease increase nodule risk. Most benign nodules are colloid cysts or adenomas. Malignancy risk is higher in nodules with irregular margins, microcalcifications, taller-than-wide shape, or internal vascularity on ultrasound.
How We Evaluate
Thyroid ultrasound is the first step and stratifies nodules using the ACR-TIRADS system. TSH is measured to identify functional nodules. Fine-needle aspiration (FNA) biopsy is recommended for nodules meeting size and ultrasound criteria. Molecular testing of FNA samples reduces the number of unnecessary surgeries for indeterminate results.
Treatment Options
Most benign nodules require ultrasound surveillance at 6–24-month intervals. Symptomatic or growing nodules may be managed with radiofrequency ablation. Surgical resection is reserved for confirmed or highly suspicious malignancy, large compressive nodules, or autonomously functioning nodules causing hyperthyroidism.
When It Is Urgent
Seek prompt care for rapid growth of a neck mass, hoarseness, difficulty swallowing, or breathing difficulty — these symptoms may indicate aggressive thyroid cancer requiring urgent evaluation.
Frequently Asked Questions
Do I need a referral to see an endocrinology provider?
No referral is needed at Nomi Beach Health. You can book directly with our team for hormone, thyroid, metabolic, or weight-management concerns.
How long does it take to see results from treatment?
Timeline depends on the condition. Thyroid medication often improves symptoms within four to eight weeks. Weight-loss interventions show measurable changes in four to twelve weeks. Hormone therapy timelines vary by the specific condition and individual response.
Will I need labs before my first visit?
You can come in without prior labs — we order whatever is appropriate during or after your visit. If you have recent results, bring them so we can start the conversation right away.
Are these conditions managed long-term or treated once?
Most endocrine and metabolic conditions require ongoing management rather than a single treatment. We build a follow-up schedule around your specific diagnosis and goals.
Can I be seen for weight loss even if I do not have a hormone diagnosis?
Yes. We evaluate weight holistically — including metabolic markers, lifestyle factors, and, when appropriate, medication options such as GLP-1 agonists.
