Overview

Tremor is an unintentional trembling or shaking movements in one or more parts of the body. It can be a symptom of neurological disorder or a side effect of certain drugs but commonly it occurs in otherwise healthy people. The most common causes of tremor are anxiety, hyperthyroidism, hypoglycemia, and alcohol withdrawal.

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.

Common Causes

• Alcohol withdrawal
• Anxiety
• Caffeine
• Hyperthyroidism
• Hypoglycemia
• Nicotine
• Parkinson's disease
