What is a common clinical symptom of hypothyroidism?

A common clinical symptom of hypothyroidism is muscle cramps. In this condition, the thyroid gland does not produce enough thyroid hormones, which are crucial for various metabolic processes in the body, including regulating energy levels and muscle function. As a result, individuals may experience muscle weakness, stiffness, and cramps, particularly in the larger muscle groups. Muscle cramps can occur due to altered metabolism, decreased activity levels, and electrolyte imbalances that may accompany hypothyroidism.

The other options represent symptoms more typically associated with hyperthyroidism or other conditions. Weight loss, palpitations, and nervousness are generally linked to an overactive thyroid rather than an underactive one. Hypothyroidism usually presents with symptoms that include fatigue, weight gain, and decreased metabolism, along with muscle discomfort, making muscle cramps a notable symptom of this disorder.
