What are common symptoms associated with hyperthyroidism?

Hyperthyroidism is a condition where the thyroid gland is overactive, producing excessive thyroid hormones. This hormonal surplus accelerates the body's metabolic processes, leading to a characteristic set of symptoms.

Weight loss occurs because the increased metabolic rate causes the body to burn calories at a faster rate than normal. This results in unintended weight decrease, even if the individual’s appetite remains the same or increases. Alongside weight loss, palpitations are frequently reported due to heightened cardiovascular activity. The increased level of thyroid hormones stimulates the heart, leading to a racing heart or feelings of fluttering in the chest.

Common additional symptoms of hyperthyroidism include increased perspiration, anxiety, tremors, and sometimes difficulty sleeping. These symptoms arise as the body’s systems are pushed into overdrive by the excess thyroid hormones. The combination of weight loss and palpitations aligns well with the classical presentation of hyperthyroidism, making it the correct choice for identifying common symptoms associated with this condition.
