Why tremors occurs in hyperthyroidism?

Tremors in hyperthyroidism occur due to an increased level of thyroid hormones, particularly thyroxine (T4), which stimulates the nervous system. This heightened metabolic state leads to increased muscle activity and heightened sensitivity of the neuromuscular junctions, resulting in fine motor tremors. Additionally, the elevated levels of catecholamines, such as adrenaline, can further contribute to muscle tremors. Together, these factors disrupt normal muscle control, leading to the characteristic tremors associated with hyperthyroidism.
