Fatigue and lethargy are common symptoms of hypothyroidism in older adults due to the role of thyroid hormones in regulating metabolism and energy levels. When there is an insufficient production of these hormones, individuals often experience a decrease in overall energy, leading to persistent tiredness and a general lack of motivation.

This symptom is particularly critical to recognize in older adults, as they may attribute fatigue to normal aging processes or other underlying health conditions. Identifying fatigue as a symptom can prompt further evaluation for hypothyroidism, allowing for timely intervention and management of the condition. The connection between reduced thyroid hormone levels and metabolic energy can explain why fatigue often stands out as a symptom among this demographic.
