## Abstract

Hypothyroidism, also known as an underactive thyroid, is an endocrine condition in which the thyroid gland does not produce enough thyroid hormones to meet the body’s needs. Hypothyroidism can develop slowly over time and cause a variety of symptoms, including fatigue, muscle weakness and stiffness, cold intolerance, brain fog, anxiety, limb numbness or tingling sensation, and palpitations. The following case describes a 32-year-old female who presented with anxiety-like symptoms closely resembling the classic symptomatology of hypothyroidism. These symptoms led to a 10-month misdiagnosis of generalized anxiety disorder. The patient had never been tested for hypothyroidism, nor had she undergone a thyroid panel. Following additional assessments, the patient was diagnosed with hypothyroidism, which emphasizes the necessity of conducting a comprehensive evaluation of the endocrine system and potential root causes in individuals exhibiting anxiety-like symptoms. This case report highlights the importance of conducting thorough medical and endocrine evaluations in patients with anxiety-like symptoms to prevent misdiagnosis, avoid unnecessary treatments, and ensure proper care.
