In simple words: Thyrotoxicosis with diffuse goiter is a condition where your thyroid gland produces too much thyroid hormone, causing it to swell up. This overproduction leads to a variety of symptoms, like a racing heart, weight loss, and nervousness.

Thyrotoxicosis with diffuse goiter is an autoimmune condition characterized by the overproduction of thyroid hormones (T3 and T4) and a diffusely enlarged thyroid gland.It's often caused by Graves' disease, where antibodies stimulate the thyroid to produce excess hormones. Symptoms include an enlarged thyroid gland, difficulty swallowing, protruding eyeballs, moist skin, anxiety, nervousness, rapid heart rate, fatigue, muscle weakness, heat intolerance, excessive sweating, tremors, and weight loss.

Example 1: A 35-year-old female presents with nervousness, weight loss despite increased appetite, and palpitations.Physical exam reveals an enlarged thyroid, rapid heart rate, and tremors.Lab results confirm elevated T3/T4 and suppressed TSH levels, leading to a diagnosis of thyrotoxicosis with diffuse goiter (Graves' disease)., A 45-year-old male with a history of goiter experiences sudden worsening of thyrotoxicosis symptoms, including high fever, delirium, and tachycardia.This acute exacerbation is diagnosed as a thyroid storm (E05.5) secondary to his underlying E05.0., A 28-year-old woman presents with palpitations and heat intolerance.She is found to have a diffusely enlarged thyroid gland.Blood tests show elevated free T4 and T3 and suppressed TSH, indicating thyrotoxicosis. She is diagnosed with E05.0, with further evaluation for Graves' disease.

Documentation should include the type and severity of thyrotoxicosis, presence or absence of goiter, presence of complications (e.g., ophthalmopathy, thyroid storm), results of thyroid function tests, imaging studies, and treatment plan.
