Physiological: anxiety, nervousness, fatigue, coffee or strong tea, some drugs (such as bronchodilators, corticosteroids, statins, etc.) may cause hand tremor. 2. Pathological: such as idiopathic tremor, which can lead to involuntary tremor of the limbs, mouth, face, vocal cords, and the rest, such as Parkinson’s syndrome, cerebellar lesions, hepatomegaly, etc. may have symptoms of hand tremor, in addition to hyperthyroidism can also cause hand tremor.
