Which symptom is NOT typical of hypothyroidism?

In the context of hypothyroidism, increased appetite is not a typical symptom. Hypothyroidism is characterized by a deficiency in thyroid hormones, which leads to a slowing of the body's metabolism. This metabolic slowdown results in a variety of symptoms, including fatigue, cold intolerance, and decreased heart rate.

Individuals with hypothyroidism often experience fatigue due to the reduced metabolic rate, making them feel sluggish and tired. Cold intolerance arises because the body’s ability to generate heat is diminished, which is directly related to decreased metabolic activity. A decreased heart rate occurs as the body’s overall metabolism slows down, impacting cardiac function as well.

In contrast, increased appetite is commonly associated with hyperthyroidism, where excessive production of thyroid hormones boosts metabolic rates, often increasing hunger and leading to weight loss. Therefore, the correct answer to the question is that increased appetite is not typical of hypothyroidism.
