Thyrotoxicosis Patterns

Use this skill when a clinician suspects excess thyroid hormone as a unifying explanation for a symptom cluster.

Approach:

1. A combination of weight loss, tremor, heat intolerance, tachycardia, palpitations, anxiety, or frequent stools should raise concern for thyrotoxicosis.
2. Common etiologies include Graves disease, toxic multinodular goiter, toxic adenoma, and thyroiditis. Distinguish them with exam clues, duration, and targeted testing.
3. Focused next tests are TSH first, then free T4 and often total or free T3 if TSH is suppressed. Consider thyroid-stimulating immunoglobulins or receptor antibodies when Graves disease is likely.
4. If the case includes severe tachyarrhythmia, agitation, fever, heart failure, or altered mental status, note concern for thyroid storm and escalate.
5. When answering, give the likely syndrome, the top etiologies to separate, and the most useful next laboratory or imaging steps.

Avoid overstating the diagnosis when endocrine confirmation is still pending.
