Hyperthyroidism
Hyperthyroidism occurs when the thyroid, a butterfly-shaped gland in the neck, produces too much thyroxine. This hormone is responsible for the use of energy in the body. Thus, an excessive amount would increase metabolism, which eventually leads to anxiety, racing heartbeats, increased appetite, and night sweats. A blood test can help your doctor diagnose hyperthyroidism. Based on the result, he or she will suggest the use of beta-blockers or similar drugs to help you manage the symptoms. [6]
