Hashimoto's Thyroiditis
Hashimoto's thyroiditis is the most common cause of hypothyroidism in the United States. The immune system produces antibodies that gradually damage thyroid cells, impairing hormone production over months to years. Thyroid function can fluctuate — patients may experience swings between low and transiently elevated thyroid hormone levels before settling into hypothyroidism.
When to Book
Book a visit if symptoms are new, persistent, getting worse, or affecting daily life. Early evaluation often prevents complications.
Symptoms
Fatigue, cold intolerance, weight changes, hair thinning, cognitive slowing, mood changes, palpitations during the inflammatory phase, and a mildly enlarged, non-tender thyroid. Many patients feel unwell even when TSH is in the normal range.
Causes & Risk Factors
Autoimmune predisposition combined with environmental triggers (iodine excess, selenium deficiency, viral infections, stress, pregnancy) drives the immune response. It is eight to ten times more common in women, peaks in the 30–50 age range, and clusters with other autoimmune conditions (celiac disease, type 1 diabetes, rheumatoid arthritis).
How We Evaluate
Anti-TPO antibodies are elevated in 90–95% of cases; anti-thyroglobulin antibodies in 60–80%. TSH and free T4 establish current thyroid function status. Ultrasound shows heterogeneous, hypoechoic texture with reduced vascularity.
Treatment Options
If TSH is elevated, levothyroxine is initiated. Selenium supplementation (200 mcg/day) has evidence for reducing antibody levels and may improve quality of life. Gluten elimination is reasonable in confirmed celiac disease. We monitor TSH and symptoms every six to twelve months, adjusting treatment as the disease evolves.
When It Is Urgent
Hashimoto's is rarely urgent. Seek prompt care for symptoms of rapidly worsening hypothyroidism — severe fatigue, extreme cold intolerance, or altered mental status — or for a quickly enlarging neck mass.
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.
