Hand tremors, or uncontrollably shaky hands, can be a source of concern for many individuals. If you are reading this, chances are you are currently suffering, have suffered from, or know someone who suffers from shaky hands. So you must be aware that hand tremors can disrupt daily activities and cause emotional distress as well.
As per the National Institute Of Neurological Disorders and Stroke, hand tremors usually signify a mild degeneration of the part of the brain that controls movement coordination. To understand the science behind hand tremors, the team of OnlyMyHealth spoke to Dr Pankaj Agarwal, Senior Consultant Neurologist and Head, Department of Neurology, Global Hospitals, Parel, Mumbai.
Hand Tremors Causes
If you've ever wondered what causes hands to shake uncontrollably, it's important to understand that there can be various hidden factors. "Hand tremors themselves are not chronic diseases, but they are symptoms of underlying conditions that may be chronic," suggested Dr Agarwal.

"Severe hand tremor can be caused by various diseases including Essential tremor, Parkinson's disease, certain medications, or even just anxiety in some people," he added. Some common causes of hand tremors are:
- Essential Tremor: Essential tremors, also known as familial tremors, often run in families and usually affect the hands, but can also involve the head, voice, or other body parts. Essential tremors tend to worsen with movement and can be exacerbated by stress.
- Parkinson's Disease: Parkinson's disease degenerates your nervous system, and can cause hand tremors. These tremors typically start on one side of the body and may progress over time.
- Caffeine or Medication: Consuming excessive caffeine or certain medications, such as asthma drugs, amphetamines, or some antidepressants, can lead to hand tremors. Reducing caffeine intake or adjusting medication under medical supervision can help alleviate this type of tremor.
- Anxiety and Stress: Emotional factors like anxiety and stress can trigger temporary hand tremors. These tremors are often benign and improve with relaxation techniques, stress management, or counselling.
- Low Blood Sugar: Low blood sugar, often associated with diabetes, poor diet, or excessive insulin use, can cause hand tremors. Maintaining stable blood sugar levels through proper diet and medication management is crucial in managing this type of tremor.
- Alcohol Withdrawal: For individuals with a history of heavy alcohol consumption, withdrawals can lead to hand tremors. Medical assistance is essential during alcohol detox to manage withdrawal symptoms safely.
- Other Medical Conditions: Certain medical conditions, such as hyperthyroidism, multiple sclerosis, and certain autoimmune disorders, can lead to hand tremors as a secondary symptom.
When to Consult a Doctor?
"You should consider consulting a doctor for your hand tremors if they persist, worsen, or interfere with your daily activities. It's important to rule out underlying medical conditions or receive appropriate treatment," advised Dr Agarwal.
Depending on the diagnosis, treatment options may include medication, lifestyle changes, physical therapy, or surgery in severe cases.
In conclusion, hand tremors can have various causes, and it's crucial not to jump to conclusions without proper medical evaluation. Dr Agarwal recommended that timely medical evaluation and treatment can help manage hand tremors effectively. He further suggested that consulting a movement disorders specialist neurologist, who specialises in tremors and other movement disorders, is advisable for proper diagnosis and guidance. If you or someone you know is experiencing hand tremors, don't hesitate to seek medical advice for a comprehensive assessment and personalised treatment plan.
