Introduction

Intermittent trembling of the upper body in elderly individuals may be caused by physiological factors, or pathological conditions such as hypoglycemia and hyperthyroidism. These symptoms can be improved through general treatment and medication. Additionally, this condition could also result from upper respiratory tract infections, Parkinson's syndrome, or hepatolenticular degeneration (Wilson's disease).

Episodic trembling of the upper body in elderly individuals may be caused by physiological factors, or it could result from pathological conditions such as hypoglycemia or hyperthyroidism. Symptoms can be improved through general management or medication. The specific analysis is as follows:

1. Physiological Causes

If an elderly person is frightened, anxious, or under emotional stress, the sympathetic nervous system may become excessively activated, leading to the aforementioned symptoms. These typically gradually improve once emotions are calmed.

2. Pathological Causes

1) Hypoglycemia
During a hypoglycemic episode, low blood glucose levels may lead to insufficient oxygen supply to brain cells, resulting in the described symptoms. In such cases, prompt intake of sweets such as candy or chocolate is recommended.

2) Hyperthyroidism
Hyperthyroidism may be influenced by autoimmune disorders, dietary factors, and genetic predisposition. This condition can increase the excitability of nerve cells, causing tremors as described. Management may include medications such as methimazole tablets, propranolol hydrochloride tablets, or propylthiouracil tablets, taken as prescribed by a physician.

In addition, such symptoms may also be caused by upper respiratory tract infections, Parkinson’s syndrome, or Wilson’s disease (hepatolenticular degeneration). If symptoms persist or worsen, timely medical evaluation is essential to avoid delays in diagnosis and treatment.
