From the Guidelines
Hyperthyroidism symptoms include weight loss, palpitations, heat intolerance, tremors, anxiety, and other symptoms of hypermetabolic activity, as noted in patients with thyrotoxicosis due to thyroiditis 1. These symptoms result from excessive thyroid hormone production, which accelerates the body's metabolism. The severity varies widely between individuals, with some experiencing mild symptoms while others have more pronounced effects.
- Common symptoms of hyperthyroidism include:
- Weight loss despite increased appetite
- Rapid or irregular heartbeat
- Anxiety, irritability, and tremors in the hands and fingers
- Heat sensitivity, fatigue, and difficulty sleeping
- Increased sweating
- Enlarged thyroid gland (goiter)
- Eye-related symptoms, such as bulging eyes, redness, and discomfort, particularly in Graves' disease
- Menstrual irregularities in women and erectile dysfunction or reduced libido in men According to the most recent evidence, thyrotoxicosis due to thyroiditis may present with these symptoms, although they may be masked if the patient is taking beta-blockers 1. It is essential to seek medical attention promptly if these symptoms occur, as untreated hyperthyroidism can lead to serious complications, including heart problems, osteoporosis, and a dangerous condition called thyroid storm, characterized by extremely high body temperature, rapid heartbeat, and potential heart failure.
