Hyperthyroidism occurs when the body produces excess thyroid hormone. Symptoms such as a fast heartbeat, palpitations, nervousness, sudden weight loss, sweating, or swelling in the neck should not be ignored.
Hyperthyroidism can have different causes, including temporary inflammation/infection or autoimmune disease, so proper evaluation and testing are important.
If you experience these symptoms, consult your doctor for appropriate tests and treatment.
