Hyperthyroidism
Hyperthyroidism is a state of excess thyroid hormone that accelerates metabolism, strains the heart, and affects mood and bone density over time. Graves' disease (an autoimmune condition) is the most common cause in younger adults. Early recognition and treatment prevent complications including cardiac arrhythmia and bone loss.
When to Book
Book a visit if symptoms are new, persistent, getting worse, or affecting daily life. Early evaluation often prevents complications.
Symptoms
Palpitations or rapid heart rate, unexplained weight loss despite normal or increased appetite, heat intolerance, excessive sweating, tremor, anxiety, irritability, difficulty sleeping, frequent bowel movements, fatigue, muscle weakness, and — in Graves' disease — eye protrusion (proptosis).
Causes & Risk Factors
Graves' disease accounts for 70–80% of cases and involves antibodies stimulating the TSH receptor. Toxic multinodular goiter and a single autonomously functioning nodule are other common causes. Less frequently, thyroiditis, iodine excess (from contrast dye or amiodarone), or TSH-secreting pituitary adenoma is responsible.
How We Evaluate
Low TSH with elevated free T4 and/or free T3 confirms hyperthyroidism. TSH receptor antibodies (TRAb or TSI) distinguish Graves' disease. Thyroid ultrasound and, when needed, radioactive iodine uptake scan determine the cause and guide treatment choice.
Treatment Options
Antithyroid medications (methimazole, propylthiouracil) reduce hormone synthesis. Beta-blockers control symptoms quickly while awaiting hormone normalization. Definitive options — radioactive iodine ablation or thyroidectomy — are considered for Graves' disease that does not remit after 18–24 months or for toxic nodular disease.
When It Is Urgent
Seek emergency care for thyroid storm — fever above 104°F, rapid heart rate (above 140 bpm), confusion, or vomiting in a known or suspected hyperthyroid patient. This is a life-threatening emergency.
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.
