What is the effect of hyperthyroidism on mood and hunger?

In hyperthyroidism, the excess production of thyroid hormones can lead to a variety of psychological and physiological effects. Contrary to the choice that states it is "not usually associated with mood changes," hyperthyroidism is more often linked with mood disturbances. The elevated levels of thyroid hormones can contribute to symptoms such as anxiety, irritability, and restlessness, which represent mood changes rather than a lack of association.

Additionally, hyperthyroidism also affects appetite. Patients commonly experience increased appetite due to heightened metabolism, but this can be accompanied by weight loss as the body's caloric needs often exceed intake. This complex interplay between mood and hunger in hyperthyroidism highlights significant changes rather than suggesting a neutral effect.

Therefore, while "not usually associated with mood changes" suggests a lack of mood-related symptoms, the reality is that hyperthyroidism typically leads to notable mood alterations and changes in hunger patterns.
