A 21 year old lady presented with history of tiredness, weight gain, depression and excessive somnolence. What will not be seen: March 2012
**Core Concept**
The question is testing the student's knowledge of the clinical presentation of hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormones. Thyroid hormones play a crucial role in regulating metabolism, energy production, and overall bodily functions.
**Why the Correct Answer is Right**
In hypothyroidism, the production of thyroid hormones is impaired, leading to a decrease in metabolic rate, weight gain, fatigue, depression, and excessive somnolence. The patient's symptoms are classic manifestations of hypothyroidism. The absence of a specific physical examination finding can help differentiate between hypothyroidism and other conditions that may present with similar symptoms.
**Why Each Wrong Option is Incorrect**
* **Option A:** **Goiter** is a common physical examination finding in hypothyroidism due to the enlargement of the thyroid gland. Therefore, it would be seen in this patient.
* **Option B:** **Bradycardia** is a possible finding in hypothyroidism due to the decreased metabolic rate and impaired cardiac function. Hence, it would be present in this patient.
* **Option C:** **Hirsutism** is not typically seen in hypothyroidism. Hirsutism is more commonly associated with hyperthyroidism or polycystic ovary syndrome (PCOS). This makes **Option C** the correct answer.
**Clinical Pearl / High-Yield Fact**
Hypothyroidism can mimic other conditions, such as depression, anemia, or even myxedema crisis, which is a life-threatening complication. A high index of suspicion and a thorough physical examination are essential in diagnosing hypothyroidism.
**Correct Answer:** C.
