What are common symptoms of hyperthyroidism?

Weight loss, fever, tachycardia, and sweating are common symptoms of hyperthyroidism due to the overproduction of thyroid hormones. In this condition, the metabolism accelerates, leading to unintentional weight loss as the body burns calories at a faster rate. Fever can occur as the increased metabolic rate generates more body heat. Tachycardia, or an increased heart rate, is another hallmark, as thyroid hormones stimulate the heart to pump faster. Sweating results from heightened metabolism and the body's efforts to cool down from increased heat production. These symptoms collectively reflect the body's overactive response to the excess thyroid hormone circulating in the system.
