What is a common behavioral symptom associated with hypothyroidism?

Fatigue and depression are common behavioral symptoms associated with hypothyroidism due to the role of thyroid hormones in regulating metabolism and energy levels. When thyroid hormone production is low, individuals often experience a significant decrease in energy, leading to feelings of fatigue. Additionally, the imbalance in hormonal levels can affect mood and emotional well-being, frequently resulting in symptoms of depression.

Thyroid hormones influence neurotransmitter function and mood regulation, making this connection between hypothyroidism and depression well-documented. Individuals may also feel apathetic or find a reduced interest in activities they once enjoyed, further illustrating how hypothyroidism can impact mental health.

Other symptoms like sleep disturbances may be present but are not as directly linked to the behavioral aspect as fatigue and depression, which are more pronounced in those with low thyroid function. Hyperactivity and increased energy are characteristics more typically associated with hyperthyroidism rather than hypothyroidism.
