What is a potential consequence of untreated hypothyroidism?

Untreated hypothyroidism can lead to various physiological changes in the body, primarily due to insufficient thyroid hormones, which play a crucial role in regulating metabolism. One of the hallmark consequences of this condition is weight gain and lethargy. The lack of thyroid hormones decreases metabolic rate, resulting in reduced energy production and accumulation of body fat. Consequently, individuals may experience an increase in body weight, accompanied by feelings of fatigue and lack of energy, making lethargy a common symptom.

In terms of metabolic functions, thyroid hormones influence numerous bodily processes, including how efficiently the body utilizes energy and metabolizes nutrients. When these hormones are deficient, the body's ability to perform these functions diminishes, leading to the clinical manifestations that include weight gain and a profound sense of tiredness or lethargy. Understanding these aspects helps in recognizing the importance of early diagnosis and treatment of hypothyroidism to mitigate these adverse outcomes.
